SHPAO6RP24CM Heat Pumps Arctic Split
Product Information: Heat Pump Arctic Split Series
The Centrometal Split Heat Pump is a heating and cooling system
that can be configured to run with or without an electric heater
and can also be used in conjunction with an auxiliary heat source
such as a boiler. It comes in three different configurations which
affect the size of the heat pump required for installation. The
outdoor unit has different capacities depending on the model and
power supply, ranging from 6kW to 16kW. The hydronic box also
varies in model and power supply and is compatible with the outdoor
unit models.
Product Usage Instructions
System Configuration
The first step in configuring the Centrometal Split Heat Pump is
to determine the total heat load by calculating the conditioned
surface area, selecting the heat emitters, and determining the
water temperature and heat load. Next, decide whether to include an
auxiliary heat source and set its switching temperature. Finally,
decide whether the backup electric heater is enabled or
disabled.
Outdoor Unit Selection
To select the appropriate outdoor unit, determine the required
total heat load on the unit and then set the capacity safety
factor. Finally, select the appropriate power supply.
Installation, Use, and Maintenance
For detailed instructions on how to install, use, and maintain
the Centrometal Split Heat Pump, refer to the technical manual
provided by Centrometal. The manual contains information on
engineering data, installation and field settings, system
configurations, unit capacities, nomenclature, and system design
and unit selection.

1 System Configura ons
Centrometal Split heat pumps can be configured to run with the electric heater
either enabled or disabled and can also be used in conjunc on with an
auxiliary heat source such as a boiler.
The chosen configura on affects the size of heat pump that is required. Three
typical configura ons are described below. Refer to Figure 1-1.
Configura on 1: Heat pump only § The heat pump covers the required capacity
and no extra hea ng capacity is necessary. § Requires selec on of larger
capacity heat pump and implies higher ini al investment. § Ideal for new
construc on in projects where energy efficiency is paramount.
Configura on 2: Heat pump and backup electric heater § Heat pump covers the
required capacity un l the ambient temperature drops below the point at which
the heat pump is able to provide sufficient capacity. When the ambient
temperature is below this equilibrium point (as shown in Figure 1-1), the
backup electric heater supplies the required addi onal hea ng capacity. § Best
balance between ini al investment and running costs, results in lowest
lifecycle cost. § Ideal for new construc on.
Configura on 3: Heat pump conjunc on with auxiliary heat source § Heat pump
covers the required capacity un l the ambient temperature drops below the
point at which the heat pump is able to provide sufficient capacity. When the
ambient temperature is below this equilibrium point (as shown in Figure 1-1),
depending on the system se ngs, either the auxiliary heat source supplies the
required addi onal hea ng capacity or the heat pump does not run and the
auxiliary heat source covers the required capacity. § Enables selec on of
lower capacity heat pump. § Ideal for refurbishments and upgrades.

Notes: 1. If the required water temperatures of the heat emi ers are not all
the same, the Centrometal heat pump Split’s outlet water temperature se ng
should be set at the highest of the heat emi er required water temperatures.
If the water outlet design temperature falls between two temperatures listed
in the outdoor unit’s capacity table, calculate the corrected capacity by
interpola on.
2. If the outdoor unit selec on is to be based on total hea ng load and total
cooling load, select Split units which sa sfy both total hea ng and cooling
load requirements.

4.2 Heat Pump Leaving Water Temperature (LWT) Selec on
The recommended design LTW ranges for different types of heat emi er are: §
For floor hea ng: 30 to 35C § For fan coil units: 30 to 45C § For low
temperature radiators: 40 to 50C
4.3 Op mizing System Design
To get the most comfort with the lowest energy consump on with heat pump, it
is important to take account of the following considera ons:
§ Choose heat emi ers that allow the heat pump system to operate at as low a
hot water temperature as possible whilst s ll providing sufficient hea ng.
§ Make sure the correct weather dependency curve is selected to match the
installa on environment (building structure, climate) as well as ender user’s
demands.
§ Connec ng room thermostats (field supplied) to the hydronic system helps
prevent excessive space hea ng by stopping the outdoor unit and circulator
pump when the room temperature is above the thermostat set point.

1.1 Notes for Installers Boxes
The informa on contained in this Technical manual may primarily be of use
during the system design stage of a Centrometal Split heat pump project. Addi
onal important informa on which may primarily be of use during field installa
on has been placed in boxes, such as the example below, tled “Notes for
installers”.
Notes for installers
@
§ Notes for installers boxes contain important informa on which may primarily be of use during field installa on, rather than during desk-based system design.
1.2 Defini ons
In this Technical manual, the term “applicable legisla on” refers to all na
onal, local and other laws, standards, codes, rules, regula ons and other
legisla on that apply in a given situa on.
1.3 Precau ons
All system installa on including installa on of refrigerant piping, water
piping and electrical works must only be carried out by competent and suitably
qualified, cer fied and accredited professionals and in accordance with all
applicable legisla on.

2.1 Acceptance and Unpacking
Notes for installers
@
§ When units are delivered check whether any damage occurred during shipment.
If there is damage to the
surface or outside of a unit, submit a wri en report to the shipping company.
§ Check that the model, specifica ons and quan ty of the units delivered are
as ordered. § Check that all accessories ordered have been included. Retain
manuals for future reference.
2.2 Hois ng
Notes for installers
@
§ Do not remove any packaging before hois ng. If units are not packaged or if
the packaging is damaged, use
suitable boards or packing material to protect the units. § Hoist one unit at
a me, using two ropes to ensure stability. § Keep units upright during hois ng
the outdoor unit, ensuring that the angle to the ver cal does not exceed 30°.

Part 3
2.3 Outdoor unit
2.3.1 Placement Considera ons Placement of the outdoor unit should take
account of the following considera ons:
Outdoor units should not be exposed to direct radia on from a high-temperature
heat source. Outdoor units should not be installed in posi ons where dust or
dirt may affect heat exchangers. Outdoor units should not be installed in loca
ons where exposure to oil or to corrosive or harmful gases, such as acidic or
alkaline gases, may occur. Outdoor units should not be installed in loca ons
where exposure to salinity may occur. Outdoor units should be installed in
well-drained, well-ven lated posi ons. Outdoor units should be installed in
loca ons where the noise from the unit will not disturb neighbors.
2.3.2 Strong Wind Installa on Wind of 5m/s or more blowing against an outdoor
unit’s air outlet blocks the flow of air through the unit, leading to
deteriora on in unit capacity, accelerated frost accumula on when in hea ng
mode or domes c hot water mode, and poten al Figure 3-2.1: Strong wind
installa on direc on disrup on to opera on due to increased pressure in the
refrigerant circuit. Exposure to very strong wind can also cause the fan to
rotate excessively fast, poten ally leading to damage to the fan. In loca ons
where exposure to high winds may occur should take account of the following
considera ons:
For installa on of the outdoor unit in a place where the wind direc on can be
foreseen. Set the outlet side at a right angle to the direc on of the wind,
refer to Figure 3-2.1. If turn the air outlet side toward the building’s wall,
fence or screen. Make sure there is enough room to do the installa on
2.3.3 Cold Climate Installa on In cold climate loca ons installa on should
take account of the following considera ons:
Never install the unit at a site where the suc on side may be exposed directly
to wind. To prevent exposure to wind, install a baffle plate on the air
discharge side of the unit. To prevent exposure to wind, install the unit with
its suc on side facing the wall. In areas of heavy snowfall, a canopy should
be installed to prevent snow entering the unit. Addi onally, the height of the
base structure should be increased so as to raise the unit further off the
ground. Refer to Figure 3-2.2.
Figure 3-2.2: Snow shielding
2.3.4 Hot Climate Installa on As the outdoor temperature is measured via the outdoor unit air thermistor, make sure to install the outdoor unit in the shade or a canopy should be constructed to avoid direct sunlight, so that it is not influenced by the sun’s heat, otherwise protec on may be possible to the unit.
2.3.5 Base Structure Outdoor unit base structure design should take account of
the following considera ons:
A solid base prevents excess vibra on and noise. Outdoor unit bases should be
constructed on solid ground or on structures of sufficient strength to support
the unit’s weight.
Technical manual Heat pumps – Split
37
Part 3
Bases should be at least 100mm high to provide sufficient drainage and to
prevent water ingress into the base of the unit. Either steel or concrete
bases may be suitable. Outdoor units should not be installed on suppor ng
structures that could be damaged by water build-in in the event of a blocked
drain. Fix the unit securely to founda on by means of the 10 expansion bolt.
It is best to screw in the founda on bolts un l their length is 20 mm from the
founda on surface.
Figure 3-2.3: Outdoor unit fixing
2.3.6 Drainage Drainage ditch should be provided to allow drainage of
condensate that may form on the air side heat exchanger when the unit is
running in hea ng mode or domes c hot water mode. The drainage should ensure
that condensate is directed away from roadways and footpaths, especially in
loca ons where the climate is such that condensate may freeze.

2.3.7 Transporta on support For 16kW model, there is a transporta on support
which is used to protect tubes from breaking during transporta on and this
support should be taken off before turning on the heat pump.

2.3.8 Spacing Single unit installa on Outdoor unit must be spaced such that
sufficient air may flow through each unit. Sufficient airflow across heat
exchangers is essen al for outdoor units to func on properly.

2.4 Hydronic box
2.4.1 Placement Considera ons Hydronic box should be installed in posi ons
that are as close as possible to the heat emi ers. Hydronic box should be
installed in posi ons that are sufficiently close to the desired posi on of
the wired controller that the controller’s wiring length limita on will not be
exceeded. In systems that are configured to heat domes c hot water, hydronic
box should be installed in posi ons that are sufficiently close to the domes c
hot water tank that the temperature sensor wiring length limita ons will not
be exceeded.
2.4.2 Moun ng the hydronic box
Fix the wall moun ng bracket to the wall using appropriate plugs and screws.
Figure 3-2.12: Wall bracket
Figure 3-2.13: Hydronic box backside
Make sure the wall moun ng bracket is completely level. When the unit is not
installed level, air might get trapped in the water circuit resul ng in
malfunc oning of the unit. Pay special a en on to this when installing the
hydronic box to prevent overflow of the drain pan. Hang the hydronic box on
the wall moun ng bracket. Fix the hydronic box at the bo om inside using
appropriate plugs and screws. The hydronic box is equipped with 2 holes at the

3.3 Procedure and Principles
3.3.1 Installa on procedure
Notes for installers
@
Installa on of the refrigerant piping system should proceed in the following order:
Pipe insula on
Pipe brazing and installa on
Pipe flushing
Gas ghtness test
Joint insula on
Part 3
Vacuum drying
Note: Pipe flushing should be performed once the brazed connec ons have been completed with the excep on of the final connec ons to the indoor units. That is, flushing should be performed once the outdoor units have been connected but before the indoor units are connected.
3.3.2 Three principles for refrigerant piping
Reasons
CLEAN DRY
Par cles such as oxide produced during brazing and/or building dust can lead
to compressor malfunc on
Moisture can lead to ice forma on or oxidiza on of internal components leading
to abnormal opera on or compressor damage
SEALED
Imperfect seals can lead to refrigerant leakage

3.4 Storing Copper Piping
3.4.1 Pipe delivery, storage and sealing
Notes for installers
@
§ Ensure that piping does not get bent or deformed during delivery or whilst
stored. § On construc on sites store piping in a designated loca on. § To
prevent dust or moisture entering , piping should be kept sealed whilst in
storage and un l it is about to be
connected. If piping is to be used soon, seal the openings with plugs or
adhesive tape. If piping is to be stored for a long me, charge the piping with
nitrogen at 0.2-0.5MPa and seal the openings by brazing. § Storing piping
directly on the ground risks dust or water ingress. Wooden supports can be
used to raise piping off the ground. § During installa on, ensure that piping
to be inserted through a hole in a wall is sealed to ensure dust and/or
fragments of wall do not enter. § Be sure to seal piping being installed
outdoors (especially if being installed ver cally) to prevent rain entering.
3.5 Manipula ng Copper Piping
3.5.1 De-oiling
Notes for installers
@
§ Lubrica on oil used during some copper pipe manufacturing processes can cause deposits to form in R32 refrigerant systems, causing system errors. Oil- free copper piping should therefore be selected. If ordinary (oily) copper piping is used, it must be cleaned with gauze dipped in tetrachloroethylene solu on prior to installa on.
Cau on § Never use carbon tetrachloride (CCl4) for pipe cleansing or flushing, as doing so will seriously damage the system.
3.5.2 Cu ng copper piping and removing burrs
Notes for installers
@
§ Use a pipe cu er rather than a saw or cu ng machine to cut piping. Rotate
the piping evenly and slowly, applying even force to ensure that the piping
does not become deformed during cu ng. Using a saw or cu ng machine to cut
piping runs the risk of copper shavings entering the piping. Copper shavings
are difficult to remove and pose a serious risk to the system if they enter
the compressor or block the thro ling unit.
§ A er cu ng using a pipe cu er, use a reamer/scraper to remove any burrs that
have formed at the opening, keeping the opening of the piping downwards to
avoid copper shavings from entering the piping.
§ Remove burrs carefully to avoid scratches, which may prevent a proper seal
being formed and lead to refrigerant leakage.

3.5.3 Expanding copper piping ends
Notes for installers
@
§ Ends of copper piping can be expanded so that another length of piping can
be inserted and the joint brazed. § Insert the expanding head of the pipe
expander into the pipe. A er comple ng pipe expansion, rotate the
copper pipe a few degrees to rec fy the straight line mark le by the expanding
head.
Cau on § Ensure that the expanded sec on of piping is smooth and even. Remove any burrs that remain a er cu ng.
Figure 3-3.2: Expanding copper piping ends
3.5.4 Flared joints Flared joints should be used where a screw thread connec on is required.
Notes for installers
@
§ Before flaring 1/2H (half hard) piping, anneal the end of the pipe to be
flared. § Remember to place the flare nut on the piping before flaring. §
Ensure the flared opening is not cracked, deformed or scratched, otherwise it
will not form a good seal and
refrigerant leakage may occur. § The diameter of the flared opening should be
within the ranges specified in Table 3-3.3. Refer to Figure 3-3.3.

3.5.5 Bending piping
Bending copper piping reduces the number of brazed joints required and can improve quality and save material.
Notes for installers
@
Piping bending methods § Hand bending is suitable for thin copper piping (6.
35mm – 12. 7mm). § Mechanical bending (using a bending spring, manual bending
machine or powered bending machine) is suitable
for a wide range of diameters (6. 35mm – 54.0mm).
Cau on § When using a spring bender, ensure that the bender is clean before inser ng it in the piping. § After bending a copper pipe, ensure that there are no wrinkles or deforma on on either side of the pipe. § Ensure that bend angles do not exceed 90°, otherwise wrinkles may appear on the inner side of the pipe, and the pipe may buckle or crack. Refer to Figure 3-3.4. § Do not use a pipe that has buckled during the bending process; ensure that the cross sec on at the bend is greater than 2/3 of the original area.
Figure 3-3.4: Pipe bending in excess of 90°
3.6 Refrigerant Piping Supports
When the air condi oning is running, the refrigerant piping will deform
(shrink, expand and droop). To avoid damage to piping, hangers or supports
should be spaced as per the criteria in the Table 3-3.4. In general, the gas
and liquid pipes should be suspended in parallel and the interval between
support points should be selected according to the diameter of the gas pipe.
Table 3-3.4: Refrigerant piping support spacings

Suitable insula on should be provided between the piping and the supports. If wooden dowels or blocks are to be used, use wood that has undergone preserva ve treatment.
Changes in refrigerant flow direc on and refrigerant temperature result in movement, expansion and shrinkage of the refrigerant piping. Piping should therefore not be fixed too ghtly, otherwise stress concentra ons may occur in the piping, with the poten al for rupturing.

3.7 Brazing
Care must be taken to prevent oxide forming on the inside of copper piping during brazing. The presence of oxide in a refrigerant system adversely affects the opera on of valves and compressors, poten ally leading to low efficiency or even compressor failure. To prevent oxida on, during brazing nitrogen should be flowed through the refrigerant piping.
Notes for installers
@
Warning § Never flow oxygen through piping as doing so aids oxida on and could
easily lead to explosion and as such is
extremely dangerous. § Take appropriate safety precau ons such as having a
fire ex nguisher to hand whilst brazing.
Flowing nitrogen during brazing § Use a pressure reducing valve to flow
nitrogen through copper piping at 0.02-0.03MPa during brazing. § Start the
flow before brazing starts and ensure that the nitrogen con nuously passes
through the sec on being
brazed un l the brazing is complete and the copper has cooled down completely.

§ When joining a shorter sec on of piping to a longer sec on, flow nitrogen
from the shorter side to allow be er displacement of air with nitrogen.
§ If the distance from the point where nitrogen enters the piping to the joint
to be brazed is long, ensure that the nitrogen is flowed for sufficient me to
discharge all the air from the sec on to be brazed before commencing brazing.

3.8 Pipe Flushing
3.8.1 Purpose To remove dust, other par cles and moisture, which could cause
compressor malfunc on if not flushed out before the system is run, the
refrigerant piping should be flushed using nitrogen. As described in Part 3,
3.3.1 “Installa on procedure”, pipe flushing should be performed once the
piping connec ons have been completed with the excep on of the final connec
ons to the hydronic box. That is, flushing should be performed once the
outdoor unit have been connected but before the hydronic box is connected.
3.8.2 Procedure
Notes for installers
@
Warning Only use nitrogen for flushing. Using carbon dioxide risks leaving condensa on in the piping. Oxygen, air, refrigerant, flammable gases and toxic gases must not be used for flushing. Use of such gases may result in fire or explosion.
Procedure The liquid and gas sides can be flushed simultaneously; alterna
vely, one side can be flushed first and then Steps 1 to 6 repeated, for the
other side. The flushing procedure is as follows:
1. A ach a pressure reducing valve to a nitrogen cylinder. 2. Connect the
pressure reducing valve outlet to the inlet on the liquid (or gas) side of the
outdoor unit. 3. Start to open the nitrogen cylinder valve and gradually
increase the pressure to 0.5MPa. 4. Allow me for nitrogen to flow as far as
the opening at hydronic box. 5. Flush the opening:
a) Using suitable material, such as a bag or cloth, press firmly against the
opening at hydronic box. b) When the pressure becomes too high to block with
your hand, suddenly remove your hand allowing gas to
rush out. c) Repeatedly flush in this manner un l no further dirt or moisture
is emi ed from the piping. Use a clean
cloth to check for dirt or moisture being emi ed. Seal the opening once it has
been flushed. 6. Once flushing is complete, seal the opening to prevent dust
and moisture from entering.

Part 3
3.9 Gas ghtness Test
3.9.1 Purpose To prevent faults caused by refrigerant leakage, a gas ghtness
test should be performed before system commissioning.
3.9.2 Procedure
Notes for installers
@
Warning Only dry nitrogen should be used for gas ghtness tes ng. Oxygen, air, flammable gases and toxic gases must not be used for gas ghtness tes ng. Use of such gases may result in fire or explosion.
Procedure The gas ghtness test procedure is as follows: Step 1
§ Once the piping system is complete and the hydronic box and outdoor unit
have been connected, vacuum the piping to -0.1MPa.
Step 2 § Charge the piping with nitrogen at 0.3MPa and leave for at least 3
minutes to check large leakage, then 1.5MPa leave for at least 3 minutes to
check small leakage, finally 4.3MPa leave for at least 24 hours to check micro
leakage. § A er the test period of at least 24 hours, observe the pressure in
the piping and assess whether or not the observed pressure indicates the
presence of a leak. Allow for any change in ambient temperature over the test
period by adjus ng the reference pressure by 0.01MPa per 1°C of temperature
difference. Adjusted reference pressure = Pressure at pressuriza on +
(temperature at observa on temperature at pressuriza on) x 0.01MPa. Compare
the observed pressure with the adjusted reference pressure. If they are the
same, the piping has passed the gas ghtness test. § If the observed pressure
is lower than the adjusted reference pressure, the piping has failed the test.
Refer to Part 3, 3.9.3 “Leak detec on”. Once the leak has been found and
fixed, the gas ghtness test should be repeated.
Step 3 § If not con nuing straight to vacuum drying (see Part 3, 3.10 “Vacuum
Drying”) once the gas ghtness test is complete, reduce the system pressure to
0.5-0.8MPa and leave the system pressurized un l ready to carry out the vacuum
drying procedure.

3.9.3 Leak detec on
Notes for installers
@
The general methods for iden fying the source of a leak are as follows: 1.
Audio detec on: rela vely large leaks are audible. 2. Touch detec on: place
your hand at joints to feel for escaping gas. 3. Soapy water detec on: small
leaks can be detected by the forma on of bubbles when soapy water is applied
to a joint.
Figure 3-3.11: Leak detec on
A: Liquid side stop valve B: Gas side stop valve C/D: Connect joints between
outdoor unit and hydronic box
4. Refrigerant leak detec on: for leaks that are difficult to detect, refrigerant leak detec on may be used as follows: a) Pressurize the piping with nitrogen at 0.3MPa. b) Add refrigerant into the piping un l the pressure reaches 0.5MPa. c) Use a halogen refrigerant detector to find the leak. d) If the leak source cannot be found, con nuing charging with refrigerant to a pressure of 4.3 MPa and then search again.
3.10 Vacuum Drying
3.10.1 Purpose Vacuum drying should be performed in order to remove moisture
and non-condensable gases from the system. Removing moisture prevents ice
forma on and oxidiza on of copper piping or other internal components. The
presence of ice par cles in the system would cause abnormal opera on, whilst
par cles of oxidized copper can cause compressor damage. The presence of non-
condensable gases in the system would lead to pressure fluctua ons and poor
heat exchange performance.
Vacuum drying also provides addi onal leak detec on (in addi on to the gas
ghtness test).
Technical manual Heat pumps – Split

Part 3
3.10.2 Procedure
Notes for installers
@
During vacuum drying, a vacuum pump is used to lower the pressure in the piping to the extent that any moisture present evaporates. At 5mmHg (755mmHg below typical atmospheric pressure) the boiling point of water is 0°C . Therefore a vacuum pump capable of maintaining a pressure of -755mmHg or lower should be used. Using a vacuum pump with a discharge in excess of 4L/s and a precision level of 0.02mmHg is recommended.
Cau on § Before performing vacuum drying, make sure that the outdoor unit stop valves are firmly closed. § Once the vacuum drying is complete and the vacuum pump is stopped, the low pressure in the piping could suck vacuum pump lubricant into the air condi oning system. The same could happen if the vacuum pump stops unexpectedly during the vacuum drying procedure. Mixing of pump lubricant with compressor oil could cause compressor malfunc on and a one-way valve should therefore be used to prevent vacuum pump lubricant seeping into the piping system.
Procedure The vacuum drying procedure is as follows: Step 1
§ Connect the blue (low pressure side) hose of a pressure gauge to the outdoor
unit gas pipe stop valve, the red (high pressure side) hose to the outdoor
unit liquid pipe stop valve and the yellow hose to the vacuum pump.
Step 2 § Start the vacuum pump and then open the pressure gauge valves to
start vacuum the system. § A er 30 minutes, close the pressure gauge valves. §
A er a further 5 to 10 minutes check the pressure gauge. If the gauge has
returned to zero, check for leakages in the refrigerant piping.
Step 3 § Re-open the pressure gauge valves and con nue vacuum drying for at
least 2 hours and un l a pressure difference of 756mmHg or more has been
achieved. Once the pressure difference of at least 756mmHg has been achieved,
con nue vacuum drying for 2 hours.
Step 4 § Close the pressure gauge valves and then stop the vacuum pump. § A er
1 hour, check the pressure gauge. If the pressure in the piping has not
increased, the procedure is finished. If the pressure has increased, check for
leakages. § A er vacuum drying, keep the blue and red hoses connected to the
pressure gauge and to the outdoor unit stop valves, in prepara on for
refrigerant charging (see Part 3, 3.11 “Charging Refrigerant”).

3.11.2 Adding refrigerant
Notes for installers
@
Cau on § Only charge refrigerant a er performing a gas ghtness test and vacuum
drying. § Never charge more refrigerant than required as doing so can lead to
liquid hammering. § Only use refrigerant R32 – charging with an unsuitable
substance may cause explosions or accidents. § Use tools and equipment
designed for use with R32 to ensure required pressure resistance and to
prevent
foreign materials from entering the system. § Refrigerant must be treated in
accordance with applicable legisla on. § Always use protec ve gloves and
protect your eyes when charging refrigerant. § Open refrigerant containers
slowly. § Keep the site well ven lated, no igni on source and fire ex nguisher
in hand for R32 is a flammable refrigerant.
Procedure The procedure for adding refrigerant is as follows: Step 1
§ Calculate addi onal refrigerant charge R (kg) (see Part 3, 3.11.1 “Calcula
ng Addi onal Refrigerant Charge”) Step 2
§ Place a tank of R32 refrigerant on a weighing scale. Turn the tank upside
down to ensure refrigerant is charged in a liquid state.
§ A er vacuum drying (see Part 3, 3.10 “Vacuum Drying”), the blue and red
pressure gauge hoses should s ll be connected to the pressure gauge and to the
outdoor unit stop valves.
§ Connect the yellow hose from the pressure gauge to the R32 refrigerant tank.
Step 3
§ Open the valve where the yellow hose meets the pressure gauge, and open the
refrigerant tank slightly to let the refrigerant eliminate the air. Cau on:
open the tank slowly to avoid freezing your hand.
§ Set the weighing scale to zero.

Step 4 · Open the three valves on the pressure gauge to begin charging
refrigerant. · When the amount charged reaches R (kg), close the three valves.
If the amount charged has not reached R (kg) but no addi onal refrigerant can
be charged, close the three valves on the pressure gauge, run the outdoor unit
in cooling mode, and then open the yellow and blue valves. Con nue charging un
l the full R (kg) of refrigerant has been charged, then close the yellow and
blue valves. Note: Before running the system, be sure to complete all test run
checks as listed in Part 3, 8.15 “TEST RUN” and be sure to open stop valves as
running the system with the stop valves closed would damage the compressor.

4 Water Pipework
4.1 Water Circuit Checks
Hydronic box are equipped with a water inlet and outlet for connec on to a
water circuit. Centrometal Split units should only be connected to closed
water circuits. Connec on to an open water circuit would lead to excessive
corrosion of the water piping. Only materials complying with all applicable
legisla on should be used. Before con nuing installa on of the unit, check the
following:
The maximum water pressure 3 bar. The maximum water temperature 70°C according
to safety device se ng. Always use materials that are compa ble with the water
used in the system and with the materials used in the unit. Ensure that
components installed in the field piping can withstand the water pressure and
temperature. Drain taps must be provided at all low points of the system to
permit complete drainage of the circuit during maintenance. Air vents must be
provided at all high points of the system. The vents should be located at
points that are easily accessible for service. An automa c air purge is
provided inside the unit. Check that this air purge valve is not
ghtened so that automa c release of air in the water circuit is possible.
4.2 Water volume and sizing expansion vessels
The units are equipped with an expansion vessel of 8L that has a default pre-
pressure of 1.5 bar. To assure proper opera on of the unit, the pre-pressure
of the expansion vessel might need to be adjusted.
Check that the total water volume in the installa on, excluding the internal
water volume of the unit, is at least 40L. Expansion vessel volume must fit
the total water system volume. To size the expansion for the hea ng and
cooling circuit. The expansion vessel volume can follow the figure below:
Figure 3-4.1: Expansion vessel volume
Notes:
In most applica ons this minimum water volume will be sa sfactory.
In cri cal processes or in rooms with a high heat load though, extra water might be required.
When circula on in each space hea ng loop is controlled by remotely controlled valves, it is important that this
minimum water volume is kept even if all the valves are closed.

Part 3
4.3 Water Circuit Connec on
Water connec ons must be made correctly in accordance with the labels on the
hydronic box, with respect to the water inlet and water outlet. If air,
moisture or dust gets in the water circuit, problems may occur. Therefore,
always take into account the following when connec ng the water circuit:
Use clean pipes only. Hold the pipe end downwards when removing burrs Cover
the pipe end when inser ng it through a wall to prevent dust and dirt
entering. Use a good thread sealant for sealing the connec ons. The sealing
must be able to withstand the pressures and temperatures of the system. When
using non-copper metallic piping, be sure to insulate the two kinds of
materials from each other to prevent galvanic corrosion. For copper is a so
material, use appropriate tools for connec ng the water circuit. Inappropriate
tools will cause damage to the pipes
4.4 Water Circuit An -freeze Protec on
Ice forma on can cause damage to the hydronic system. All internal hydronic
parts are insulated to reduce heat loss. Insula on must also be added to the
field piping.
The so ware contains special func ons using the heat pump to protect the en re
system against freezing. When the temperature of the water flow in the system
drops to a certain value, the unit will heat the water, either using the heat
pump, the electric hea ng tap, or the backup heater. The freeze protec on func
on will turn off only when the temperature increases to a certain value. In
event of a power failure, the above features would not protect the unit from
freezing. Since a power failure could happen when the unit is una ended, the
supplier recommends use an -freeze fluid to the water system. Depending on the
expected lowest outdoor temperature, make sure the water system is filled with
a concentra on of glycol as men oned in the table below. When glycol is added
to the system, the performance of the unit will be affected. The correc on
factor of the unit capacity, flow rate and pressure drop of the system is
listed in the table 3-4.1 and 3-4.2

process is accelerated by presence of copper and at higher temperatures. The
acidic uninhibited glycol a acks metal surfaces and forms galvanic corrosion
cells that cause severe damage to the system. It is of extreme importance:
That the water treatment is correctly executed by a qualified water
specialist. That a glycol with corrosion inhibitors is selected to counteract
acids formed by the oxida on of glycols. That in case of an installa on with a
domes c hot water tank, only the use of propylene glycol is allowed. In other
installa ons the use of ethylene glycol is fine. That no automo ve glycol is
used because their corrosion inhibitors have a limited life me and contain
silicates that can foul or plug the system; That galvanized piping is not used
in glycol systems since it may lead to the precipita on of certain elements in
the glycol’s corrosion inhibitor; To ensure that the glycol is compa ble with
the materials used in the system.
4.5 Water Flow Switch
Water may enter into the flow switch and cannot be drained out and may freeze
when the temperature is low enough. The flow switch should be removed and
dried, then can be reinstalled in the unit.
Figure 3-4.2: Water flow switch
Counterclockwise rota on, remove the water flow switch. Drying the water flow switch completely.
4.6 Adding Water
Connect the water supply to the fill valve and open the valve. Make sure the
automa c air purge valve is open (at least 2 turns). Fill with water un l the
manometer indicates a pressure of approximately 2.0 bars. Remove air in the
circuit as much as possible using the air purge valve. Air in the water
circuit could lead to malfunc on of the backup electric heater.
4.7 Water Piping Insula on
The complete water circuit including all piping, water piping must be
insulated to prevent condensa on during cooling opera on and reduc on of the
hea ng and cooling capacity as well as preven on of freezing of the outside
water piping during winter. The insula on material should at least of B1 fire
resistance ra ng and complies with all applicable legisla on. The thickness of
the sealing materials must be at least 13mm with thermal conduc vity 0.039W/mK
in order to prevent freezing on the outside water piping. If the outdoor
ambient temperature is higher than 30°C and the humidity is higher than RH
80%, the thickness of the sealing materials should be at least 20mm in order
to avoid condensa on on the surface of the seal.

5 Electrical Wiring
5.1 General
Notes for installers
@
Cau on § All installa on and wiring must be carried out by competent and suitably qualified, cer fied and accredited professionals and in accordance with all applicable legisla on. § Electrical systems should be grounded in accordance with all applicable legisla on. § Overcurrent circuit breakers and residual-current circuit breakers (ground fault circuit interrupters) should be used in accordance with all applicable legisla on. § Wiring pa erns shown in this data book are general connec on guides only and are not intended for, or to include all details for, any specific installa on. § The water piping, power wiring and communica on wiring are typically run in parallel. However the communica on wiring should not be bound together with power wiring. To prevent signal interference, the power wiring and communica on wiring should not be run in the same conduit. If the power supply is less than 10A, a separa on of at least 300mm between power wiring and communica on wiring conduits should be maintained; if the power supply is in the range 10A to 50A then a separa on of at least 500mm should be maintained.
5.2 Precau ons
Fix cables so that cables do not make contact with the pipes (especially on
the high pressure side). Secure the electrical wiring with cable es so that it
does not come in contact with the piping, par cularly on the high-pressure
side. Make sure no external pressure is applied to the terminal connectors.
When installing the ground fault circuit interrupter make sure that it is
compa ble with the inverter (resistant to high frequency electrical noise) to
avoid unnecessary opening of the ground fault circuit interrupter This unit is
equipped with an inverter. Installing a phase advancing capacitor not only
reduce the power factor improvement effect, but also may cause abnormal hea ng
of the capacitor due to high frequency waves. Never install a phase advancing
capacitor as it could lead to an accident.
5.3 Guidance
Most field wiring on the unit is to be made on the terminal block inside the
switch box. To gain access to the terminal block, remove the switch box
service panel. Fix all cables using cable es. A dedicated power circuit is
required for the backup electric heater. Installa on equipped with a domes c
hot water tank (field supplied) requires a dedicated power circuit for the
immersion heater.
Secure the wiring in the order shown below: Lay out the electrical wiring so
that the front cover does not rise up when doing wiring work and a ach the
front cover securely. Follow the electric wiring diagrams for electrical
wiring works. Refer to Figure 2-4:1 to Figure 2-4:5 in part 2, 4 “Wiring
Diagram”. Install the wires and fix the cover firmly so that the cover may be
fit in properly.

7 Internal Circula on Pump
The pump is controlled via a digital low-voltage pulse-width modula on signal
which means that the speed of rota on depends on the input signal. The speed
changes as a func on of the input profile. The rela onship between external
sta c pressure and water flow rate is described in Part 2, 7 “Hydronic
Performance”.
