3.1. Scope of this manual
This manual describes the procedures for handling, installing and connecting 1U71~180 units.
3.2 Precautions
CAUTION
Since maximum working pressure is 4.3 MPa or 43.0 bar, pipes of larger wall thickness may be required. Refer to paragraph “6.2. Selection of piping material” on page 14.
NOTICE: Insulation resistance of the compressor
If, after installation, refrigerant accumulates in the compressor, the insulation resistance can drop, but if it is at least 1 , then the machine will not break down. Turn the power on and leave it on for six hours. Then, check if the insulation resistance of the comressor has risen or not.
The compressor will heat up and evaporate any refrigerant in the compressor.
Check the following if the ground-fault circuit interrupter is triggered:
Make sure that the interrupter is compatible with high frequencies.
This unit has an inverter, so an interrupter capable of handling high frequencies is needed to prevent malfunction of the interrupter itself.

3.3. Precautions for R32
◾ The refrigerant requires strict cautions for keeping the system clean, dry and tight.
– Clean and dry Foreign materials (including mineral oils or moisture) should be prevented from getting mixed into the system.
– Tight Read “9. Precautions on refrigerant piping” on page 10 carefully and follow these procedures correctly.
◾ Since R32 is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state.(If the refrigerant is in state of gas, its composition changes and the system will not work properly).
The connected indoor units must be indoor units designed exclusively for R32.

3.4. Installation
◾ For installation of the indoor unit(s), refer to the indoor unit installation manual.
◾ Illustrations show 1U125S2SP5FA outdoor unit type.

6.2. Piping Materials
6.2 Types of Copper Pipes (Reference)

• Use pipes that meet the local standards.

Piping MaterialslRadial Thickness
Use pipes made of phosphorus deoxidized copper.
Since the operation pressure of the units that use R32 is higher than that of the units for use with R22, use pipes with at least the radial thickness specified in the chart below. (Pipes with a radial thickness of 0.7mm or less may not be used.)

• Although it was possible to use type-O for pipes with a size of up to Φ19.05(3/4″) with conventional refrigerants, use type- 1/2H pipes for units that use R32. (Type-O pipes may be used if the pipe size is Φ19.05 and the radial thickness is 1.2t.)
• The table shows the standards in Japan. Using this table as a reference, choose pipes that meet the local standards.

Flare Machining (type-O and OL only)
The flare machining dimensions for units that use R32 is larger than those for units that use R22 in order to increase air tightness.
Flare Machining Dimension(mm)

If a clutch type flare tool is used to machine flares on units that use R410A, make the protruding part of the pipe between 1.0and 1.5mm. Copper pipe gauge for adjusting the length of pipe protrusion is useful.
Flare Nut
Type-2 flare nuts instead of type-1 nuts are used to increase the strength. The size of some of the flare nuts have also been changed.
Flare nut dimension(mm)

Using this table as a reference, choose pipes that meet the local standards.

◾ For new installations, use the standard pipe sizes.
When using existiong pipes, size-up is allowed as mentioned in the table above.
Additional restrictions towards allowable pipe lengths, as mentioned in the table 7.3 on page 13, must be taken into account.
Not using the standard lpipe size may result in capacity decrease. The installer must acknowledge this and judge this very carefully in function of the complete installation.
◾ Existing or pre-installed piping can be used

1. Piping must comply with the criteria below.
   • Piping diameter must comply with the limitations as indicated in paragraph “7.2. Refrigerant pipe size “.
   • Piping length must be within limits of the allowable piping length as in paragraph “7.3. Allowable pipe length and height difference”.
   • Piping must be designed for R32. See paragraph “6.2. Selection of piping material”.

2. Piping can be reused without cleaning when:
   • Total 1-way piping length: ≤ 50m.
   • No compressor breakdown has occurred in the history of the unit to be replaced.
   • A correct pump down operation can be executed:
   – Operate the unit continuously for 30minutes in cooling mode.

Precautions for refrigerant piping
◾ Do not twist or crush piping.
◾ Be sure that no dust is mixed in piping.
◾ Bend piping with as wide angle as possible.
◾ Keep insulating both gas and liquid piping.
◾ Check flare-connected area for gas leakage.
7.4. Piping connection method
◾ Apply refrigerant oil to the joint and the flange.
◾ To bend a pipe, give the roundness as possible not to crush the pipe.
◾ When connecting pipe, hold the pipe centre to centre and then screw nut on by hand, refer to Fig.
◾ Be careful not to let foreign matters, such as sands enter the pipe

◾ Field pipes can be installed in four directions (A, B, C, D, E).

B: Sideways
C: Backward
D: Downward
E: Power supply cable outdoor and indoor connection cable
◾ Cutting out the two slits makes it possible to install as shown in the figure “Field pipes in 4 directions”. (Use a metal saw to cut out the slits.)
◾ To install the connecting pipe to the unit in a downward direction, make a knock-out hole by penetrating the centre area around the knockout hole using a Ø6 mm drill (4x).
◾ After knocking out the knock-out hole, it is recommended to apply repair paint to the edge and the surrounding end surfaces to prevent rusting.
◾ When passing electrical wiring through the knock-out holes, remove any burrs from the know-out holes and wrap the wiring with protective tape to prevent damage.

7.5. Preventing foreign objects from entering
Plug the pipe through-holes with putty or insulating material (procured locally) to stop up all gaps, as shown in the figure.

If there is any possibility that small animals enter the system through the knock-out holes, plug the holes with packing materials (field supplied).
Insects or samall animals entering the outdoor unit may cause a short circuit in teh electrical box.
Seal knock-out holes to avoid snow and humidity entering.
7.6. Preventing foreign objects from entering
◾ Be careful not to let the indoor and outdoor piping come into contact with the compressor terminal cover.
If the liquid-side piping insulation might come into contact with it, adjust the height as shown in the figure below. Also, make sure the field piping does not touch the bolts or outer panels of the compressor.
◾ When the outdoor unit is installed above the indoor unit the following can occur:
The condensed water on the stop valve can move to the indoor unit. To avoid this, please cover the stop valve with sealing material.
◾ If the temperature is higher than 30and the humidity is higher than RH 80, then thickness of the sealing materials should be at least 20mm in ouder to avoid condensation on the surface of the sealing.
◾ Be sure to insulate the liquid and gas-side field piping.
NOTICE
Any exposed piping may cause condensation.
(The highest temperature that the gas-side piping can reach is around 120°C, so be sure to use insulating material which is very resistant.)
DANGER
No not touch piping and internal parts.
7.7. Cautions for necessity of a trap
To avoid the the risk of oil held inside the riser piping flowing back into the compressor when stopped and causing liquid compression phenomenon, or cases of deterioration of oil return, it will be necessary to provide a trap at each difference in height of 10m in the riser gas piping.
◾  A trap is not necessary when the outdoor unit is installed at higher position than the indoor unit.

Leak test and vacuum drying

When all piping work is complete and the outdoor unit is connected to the indoor unit, it is necessary to :
◾ check for any leakages in the refrigerant piping
◾ to perform vacuum drying to remove all moisture in the refrigerant piping.
If there is a possibility of moisture being present in the refrigerant piping (for example, rainwater may have entered the piping), first carry out the vacuum drying procedure below until all moisture has been removed.
8.1. General guidelines
◾ All piping inside the unit has been factory tested for leaks.
◾ Use a 2-stage vacuum pump with a non-return valve which can evacuate to a gauge pressure of- 100.7kPa(5 Torr absolute,-755mm Hg).
◾ Connect the vacuum pump to both the service port of the gas stop valve and the liquid stop valve to increase efficiency.
NOTICE
◾ Do not purge the air with refrigerants. Use a vacuum pump to evacuate the installation. No additional refrigerant is provided for air purging.
Make sure that the gas stop valve and liquid stop valve are firmly closed before performing the leak test or vacuum drying.
8.2. Leak test
The leak test must satisfy specification EN378-2.

1. Vacuum leak test
   1.1 Evacuate the system from the liquid and gas piping to -100.7 kPa(5 Torr).
   1.2 Once reached, turn off the vacuum pump and check that the pressure does not rise for at least 1 minute.
   1.3 Should the pressure rise, the system may either contain moisture (refer to the paragraph ” Vacuum drying “) or have leaks.

2. Pressure leak test
   2.1 Break the vacuum by pressurizing with nitrogen gas to a minimum gauge pressure of 0.2 MPa (2 bar). Never set the gauge pressure higher than  the maximum operation pressure of the unit, i.e. 4.0MPa (40bar).
   2.2 Test for leaks by applying a bubble test solution to all piping connections.

NOTICE
Make sure to use a recommended bubble test solution from your wholesaler.
Do not use soap water, which may cause cracking of falre nuts (soap water may contain salt, which absorbs moisture that will freeze when the piping gets cold). and/or lead to corrosion of flared joints (soap water may contain ammonia which causes a corrosive effect between the brass flare nut and the copper flare).

8.3. Vacuum drying
To remove all mositure from the system, proceed as follows:

1. Evacuate the system for at least 2 hours to a target vacuum of -100.7 kPa(=-1.007 bar).
2. Check that, with the vacuum pump turned off, the target vacuum is maintained for at least 1 hour.
3. Should you fail to reach the target vacuum within 2 hours or maintain the vacuum for 1 hour, the system may contain too much moisture.
4. In that case, break the vacuum by pressurizing with nigrogen gas to a gauge pressure of 0.05 MPa (0.5bar) and repeat steps 1 to 3 unit all moisture has been removed.
5. The stop valves can now be opened, and/or additional refrigerant can be charged.

INFORMATION
After opening the stop valve, it is possible that the pressure in the refrigerant piping does not rise. This migeh be caused by e.g. the closed state of the expansion valve in the outdoor unit circuit, but does not present any problem for correct operation of the unit.

Charging refrigerant

9.1 Important information regarding the refrigerant used

• This product contains fluorinated greenhouse gases covered by the Kyoto Protocol. Do not vent gases into the atmopsphere.
• Evacuate Indoor Unit and interconnecting pipework to a vacuum pressure of 500 microns and hold for 15 minutes.
• The Outdoor unit is supplied with refrigerant HFC32 (R32) sufficient for 30m line length. Calculate additional refrigerant to suit your line length; refer supplied Specification Sheet.
• Open the service valve at the Outdoor unit to allow refrigerant to flow throughout the system.
• For long line lengths, oil (of the correct type) should be added to the refrigerant system at the rate shown in the Specification Date table.(see paragraph 9.5)
• Leak check all brazed and fitted joints.

9.2. Precautions and general guidelines

◾ When servicing the unit requires the refrigerant system to be opened, treatment and evacuation of refrigerant must be done in accordance with applicable legislation. Refrigerant can not be charged until field wiring has been completed.
◾ Refrigerant may only be charged after performing the leak test and vacuum drying.
CAUTION
When charging a system, care shall be taken that its maximum permissible charge is never exceeded, in view of the danger of liquid hammer.
WARNING
◾ Refrigerant cylinders shall be opened shlowly.
◾ Always use protective gloves and protect your eyes when charging refrigerant.
DANGER
◾ When the power is on, please close the front panel when leaving the unit unattended.
Charging with an unsuitable substance may cause explosions and accidents, so always ensuren that the appropriate refrigerant (R32) is charged.
◾ This unit requires additional charging of refrigerant according to the length of refrigerant piping connected at the site.
◾ Make sure to charge the refrigerant in liquid state to the liquid pipe. Since R32 is a mixed refrigerant, its composition changes if charged in its gaseous state and normal system operation would then no longer be assured.
◾ Before charging, checkwhetherthe refrigerant cylinder has a suphon attached or not and position the cylinder accordingly.
Fill using a cylinder with a siphon attached Charge the liquid refrigerant with the cylinder in upright position. Fill using a cylinder with a siphon attached Charge the liquid refrigerant with the cylinder in upside- down position.
On this model it is not necessary to charge additionally if the piping length≤30m.
9.3. Complete recharging
NOTICE
Berore recharging, make sure to execute vacuum drying of the intermal piping of the unit as well.
To do so, use the internal service port of the unit.
Do not use the service ports located on the stop valve, since vacuum drying can not be performed properly from these ports.
Outdoor units have 1 port on the piping. It is between the heat exchanger and the 4-way valve.
In case complete recharging is required (aftera leak, etc.), refer to teh information below to determine the necessary amount of refrigerant.
WARNING
Some sections ofthe refrigerant circuit may be isolated from other sections caused by components with specificfunctions (e.g. valves).
The refrigerant circuit therefore features additional service ports for vacuuming, pressure relief or pressurizing the circuit. In case it is required to perform brazing on the unit, ensure that there is no pressure remaining inside the unit. Internal pressures need to be released with ALL the service ports indicated on the figures below opened. The location is depending on mode type.  9.4 Total charging weight of the refrigerant (after a leak, etc.)
The total charging amounts relate to the refrigerant piping length.

Electrical wiring work

WARNING
◾ All wiring must be performed by an authorized electrician.
All components procured on the side and all elecrtic construction shall comply with the applicable legislation.

DANGER: HIGH VOLTAGE.
To avoid electrical shock, make sure to disconnect the power supply 1 minute or more before servicing the electrical parts. Even after 1 minute, always measure the voltage at the terminals of main circuit capacitors or electrical parts and, before touching , make sure that those voltages are 50VDC or less.
NOTICE
To persons in charge of electrical wiring work:
Do not oerate the unit until the refrigerant piping is complete. (Running it before the piping is ready will break the compressor.)

10.1. Precautions on electrical wiring work
◾ When servicing the unit requires the refrigerant system to be opened, treatment and evacuation of refrigerant must be done in accordance with applicable legislation. Refrigerant can not be charged until field wiring has been completed.
Refrigerant may only be charged after performing the leak test and vacuum drying.
