2. Allpersonnelin charge of maintenance and people which work inthe surrounding area must be instructed on the type work they are going to carry out.

3. The zone MUST be checked with a specific refrigerating liquids detector before and during work, so that the technician is aware of potentially flammable atmospheres. Make sure the detection device of the leaks is suitable for use with flammable refrigerants, then that it does not produce sparks and that is adequately sealed or intrinsically safe.

4. The leaks electronic detectors may need calibration.
   If necessary, calibrate them in a zone free of refrigerant.

5. Make sure the detector is not a potential source of combustion and that it is suitable for the refrigerant used. The device for detection must be set at a percentage of the refrigerant LFL and must be calibrated for the used refrigerant; the appropriate percentage of gas (maximum 25 %) must be confirmed.
   5a. Fluids for the detection of losses are suitable for most part of the refrigerants.
   Detergents containing chlorine MUST be avoided.
   Danger of corrosion of copper pipes.

6. If the presence of a leak is suspected, all open flames must be removed.
   If a fluid leak which requires brazing is encountered, all refrigerant must be collected from the system or insulated (by means of shut off valves) in a part of the system away from the leak. Then, bleed nitrogen without oxygen (OFN) through the system both before and after the brazing process.

7. Incaseitis necessary to carry outa hot work onthe appliance, IT IS NECESSARY to have a powder or CO, fire extinguisher available.

8. To carry out a work which includes exposition of pipes which contain or contained a flammable refrigerant, DO NOT use sources of combustion. RISK OF FIRE OR EXPLOSION!

9. All sources of combustion (even a lit cigarette) should be kept away from the place in which all operations during which the flammable refrigerant may be released in the surrounding space must be carried out.

10. Make sure the area is adequately ventilated before intervening inside the system; a continuous degree of ventilation must be present.

11. DO NOT use means different from those recommended by the manufacturer in order to speed up the defrosting process or for cleaning.

12. Before any operation, always check that:

• the condensers are unloaded.
  The operation must be carried out safely to avoid the risk of producing sparks;

• there are no live electrical components and that the cables are not exposed while loading, recovering or bleeding the system;

• there is continuity in the ground connection. 13. All electrical power supplies must be disconnected from the appliance on which you are working.
  If it is absolutely necessary that the appliance has electrical power supply, it is necessary to place a leak detector permanently operational in the most critical point.

  14. Make sure the seals and sealing materials have not deteriorated.
      Possible development of flammable atmospheres.

  15. Do not apply any net inductive or capacity load to the circuit without making sure that this operation won’t make you exceed the voltage and current permitted for the appliance in use.

      The test device must be set with the correct conditions. The components must be replaced ONLY with parts of the manufacturer. Danger of loss of refrigerant in the atmosphere, risk of explosion.

  16. Periodically check that the cables are not subject to wear, corrosion, excessive pressure, vibrations, sharp edges or any other hostile environmental situation.

  17. When intervening inside the refrigerating circuit to carry out repairs or for any other reason, the conventional procedures must be followed:

• remove the refrigerant;

• bleed the circuit with an inert gas;

• evacuate;

• bleed again with an inert gas;

• open the circuit by cutting or by means of brazing. 18. The load of refrigerant must be stored in the specific custody cylinders.
  The system must “cleaned” with OFN to make the unit safe.
  It may be necessary to repeat this process several times.
  DO NOT use compressed air or oxygen for this operation.
  18a.Make sure that, while recharging the system THERE IS no contamination of the various elements. The pipes or conducts MUST be as short as possible to minimize the content of refrigerant inside them.

  19. The cylinders must be kept in vertical position.
      Only use cylinders suitable for collection of refrigerants.
      The cylinders must be complete of a pressure-relief valve and switch off valves in good conditions.
      A set of calibrated weighing scales must also be available.

  20. The pipes must be equipped with couplings for disconnection and must NOT present leaks.
      Before using the collection machine, check that it underwent correct maintenance and that the possible associated electric components are sealed, to prevent switching on in case of leak of refrigerant.

  21. Make sure the refrigerating system is earthed before proceeding with reloading of the system with refrigerant.
      Label the system when reloading is complete.
      Pay particular attention not to overload the refrigerating system.

  22. Before proceeding with reloading, the system must undergo the pressure : test with OFN and the tightness test at the end of reloading, but before commissioning.
      It is necessary to carry out an additional tightness test before leaving the site.
      22a. Remove the refrigerant safely. Move the refrigerant in the cylinders suitable for recovery. Make sure there is a correct number of cylinders to contain the charge entirely. All cylinders are labelled for this type of refrigerant (special cylinders for refrigerant recovery).
      The cylinders must be complete of a pressure relief valve and of and of the corresponding closure valve in good conditions. Empty cylinders are evacuated and, if possible, cooled down before recovery.
      22b.Equipment for recovery must be within the range of the technician, in good conditions, with a series of instructions and must be suitable for recovery of all the refrigerants (even flammable ones). A series of calibrates scales must be available and in good conditions. Check that the pipes are in good conditions and complete of disconnection joints without losses.
      22c.Before using the machine for recovery, check that it is in good operating conditions, that it has been adequately maintained and that all the associated electric components are sealed to prevent switching-in in case of release of refrigerant. In case of doubt, please contact the manufacturer.

  23. Collected refrigerant must be returned to the fluid supplier in the appropriate collection cylinder, compiling the corresponding Transfer Note of Scraps. DO NOT mix the refrigerants in the collection units and, in particular, in the cylinders.

  24. If the compressors or their oils must be removed, make sure they have been emptied at an acceptable level to be sure that the flammable refrigerant does not remain in the lubricant.
      This process must be carried out before the compressor retums to the suppliers. Only use electric heating on the compressor body to speed up this process.

  25. Make sure that contamination between different refrigerants does not occur when a reloading equipment is used.
      The flexible pipes or ducts must be as short as possible to reduce the quantity of refrigerant inside them to a minimum.

• Install anti-vibration blocks and a compliant power supply near the external unit.

See the manual of the external unit for more detailed information on installation.

2.4 – OPERATIONAL LIMITS
The charts define water temperature (LWT) and external air (ODT) limits within which the heat pump can work in the two cooling modes, heating and domestic water production (DHW). The parts highlighted in grey show the moment in which the electric heaters intervene in addition to the main circuit.

CONNECTIONS

3.1 – REFRIGERANT CONNECTIONS
To define the refrigerant connection lines between the internal and external units, refer to the table below.

| Sherpa S3 E
---|---
4-6 kW| 8-10-12-14-16 kW
Maximum length of the connection pipes (m)| 30| 30
Minimum length of the connection pipes (m)| 2| 2
Elevation difference limit between the two units if the external unit is positioned higher (m)| 20| 20
Elevation difference limit between the two units if the external unit is positioned lower (m)| 15| 15
Additional load of refrigerant per metre beyond 15 metres of pipes (g/m)| 20| 38

Exclusively use pipes with diameters which respect the required dimensions.
The maximum length of the connection lines to the internal unit MUST be compliant with the table in paragraph “3.1” topping up the load of R32 as envisaged (see par.3.1.2). Do not install the units beyond the maximum allowed difference in level between internal and external unit.
Complete the refrigerant circuit by connecting the internal unit with the external unit by means of the insulated copper pipes.

• Exclusively use insulated copper pipes specific for refrigeration; they must be clean and sealed at their ends.
• For models SHERPA S3 E (4-6 kW), use a reducer for the liquid pipe from 3/8” to 1/4”.

The refrigerant connections of the internal unit are behind the electric panel, the ones of the external units are on the right side and, in order to access them, it is necessary to remove the guard. (fig.9-10a-10b)

U1. Internal unit 5/8” gas line.
U2. Internal unit 3/8” liquid line.
U3. External unit 5/8” gas line valve.
U4. 1/4” liquid line valve for U.E. SHERPA S3 E (4-6 kW); 3/8” for U.E. SHERPA S3 E (8-10-12-14-16 kW).

• Identify the path of the pipes in order to reduce length and bends of the pipes as much as possible and to obtain maximum performance of the system.
• Insert the refrigerant lines in a cable gland duct (possibly with internal separator) of the appropriate dimensions fixed to the wall through which the pipes and the electric cables will pass.
• Cut the pipe sections abounding of approximately 3-4 cm on length.

Cut exclusively using a wheel pipe cutter while tightening at small intervals in order not to crush the pipe.

• Remove possible burrs using the specific tool.
• Insert the fixing nut in the pipe before flaring (fig.11).
• Flare the ends of the pipes using the specific tool flawlessly without breakages, cracks or cleavage (fig.11).
• Manually screw the nut of the pipe on the coupling thread.
• Screw completely using a fork wrench to keep the threaded part of the coupling stationary. On the nut, use a torque wrench calibrated with the following values based on the dimensions of the pipes to avoid deformations:
• Diameter 3/8’’ 34 N.m < tightening torque < 42 N.m
• Diameter 5/8’’ 68 N.m < tightening torque < 82 N.m

3.1.1 – Tests and checks

Once the connections are complete, check for perfect sealing of the refrigerant system.

To carry out the operations described below it is necessary to use a manometer unit specific for R32 and a vacuum pump with minimum flow rate of 40 l/min:

a.  Unscrew the caps of the service valves stems, both of the gas and of the liquid (fig. 13).

b.  Connect the vacuum pump and manometer unit by means of the flexible pipes with 5/16” coupling  to the service connection of the gas line (fig.14).

c.  Switch on the pump and open the taps of the manometer unit.

d.  Lower pressure up to -101kPa (-755mmHg, -1bar).

e.  Maintain underpressure for at least 1 hour.

f.  Close the taps of the manometer unit and switch off the pump.

g.  After 5 minutes, only if pressure remained at -101kPa (-755mmHg, -1bar), pass to the operation at  step “h”.

 If pressure inside the circuit raised to a value higher than -101kPa (-755mmHg, – 1bar), it is neces- sary to proceed with the search for the leak (by means of soap solution with refrigerant circuit under nitrogen pressure ~ 30 bar).

 Once the leak has been detected and repaired, it is necessary to restart from step “c”.

h.  Use a 4 mm hexagonal wrench to completely open the stem of the liquid valve.

i.  Use a 5 mm hexagonal wrench to completely open the stem of the gas valve.

l.  Remove the load flexible pipe connected to the service connection of the gas pipe.

m. Reposition the cap of the service connection of the gas pipe and fix it with a fork or normal wrench.

n.  Reposition the caps of the service valves stems, both of the gas and liquid, then secure them.

3.1.2 – Loading of additional refrigerant

• If the length of the pipes is higher than 15 m, top up the refrigerant as indicated in the table in paragraph “REFRIGERANT CONNECTIONS”.
• Indicate the data of the external unit load (1), of the additional refrigerant quantity (2) and the total load of the system (1+2) on the supplied label (fig.15).

3.2 – HYDRAULIC CONNECTIONS

• The choice and installation of the components is delegated, due to competence, to the installer which will have to work according to good practice regulations and the Law in force.
• Before connecting the pipes, make sure that they do not contain rocks, sand, rust, dregs or, in any case, foreign bodies which may damage the system.
• It is appropriate to carry out a by-pass in the system in order to be able to perform washing of the plate exchanger without disconnecting the appliance. The connection pipes must be supported so that they do not weigh on the appliance with their weight.

3.2.1 – Hydraulic circuit
The hydraulic scheme shows the main parts of the internal unit and a typical hydraulic circuit.

Install a sieve filter with 0,4 mm meshes on the water return pipes from the system.

3.2.2 – Characteristics of the system
The hydraulic couplings are positioned in the lower part of the unit.

Figure 17-17a:

– 5/8”G)
---|---

The hydraulic connections must be complete by installing (fig.5):

• air breather valves aria in the highest points of the pipes;

• please refer to “fig.5” for the position of the hydraulic and refrigerant connections. Heights are indicative, it is recommended to use flexible elastic junctions between the system pipes and the hydraulic connections of the unit;

• stop valves (on the drinkable water inlet, on the DHW outlet, on the system water return pipe, necessary to ease maintenance operations);

• sieve water filter with 0.4 mm meshes on the drinkable water inlet and on the return pipe from the system to intercept possible particles in the hydraulic system. Install in an easily accessible position during cleaning operations;

• thermally insulate all the components and the hydraulic pipes.

• In case of installation with hydraulic connections upwards (“A”), leftwards (“C”) or rightwards (“B”), it is necessary to remove from the cover the precut metal sheet part on the pipes output side.
  Use a hacksaw to remove the precut metal sheet.

• In case of installation with hydraulic connections leftwards (“C”), rightwards (“B”) or towards the rear part of the machine, use 90° sharp bends (two 1” and two 3/4”).

• Install a non-return valve on the drinkable water inlet (see paragraph “Hydraulic circuit” – rif.18).

The minimum nominal diameter of the hydraulic connection pipes must be 1”.
To allow for maintenance or repair operations, it is essential that each hydraulic connection is equipped with the corresponding manual shut-off valves.

  The charts in fig.18-18a-18b show the prevalence of the circulator for each speed of the hydraulic circulator and the load losses inside the machine from which the residual prevalence at the connections of the machine must be obtained, expendable on the system.

The circulation of the minimum content of the conditioning system be ensured even if the valves in the system are closed.

3.2.3 – Circulation pumps (fig.18-18a)
The pumps are controlled through PWM, so as to set the fixed number of revolutions for pump operation.
Sherpa Tower is equipped with one high-efficiency circulation pump.
The pumps with permanent magnet wet rotor have an electronic adjustment module with integrated frequency converter.
On the adjustment module is present a control knob.

• Check that load losses of the system ensure the required water flow rate (see par. 4.2).
• If higher prevalences should be necessary due to high load losses of the system, it’ll be necessary to add a hydraulic separator and an external reactivation pump.
• Check if the system has the minimum required content of water to ensure good op- eration of the system; if it is insufficient, add such accumulation so that the required content is reached.
• The water distribution pipelines will have to be insulated adequately with polyethylene foam or similar materials. The non-return valves, the bends and the various fittings shall also be insulated adequately.
• To avoid air pockets inside the circuit, insert the automatic or manual vent devices in all the points (highest pipelines, siphons etc.) where air may accumulate.
  To set the speed pump, please see paragraph 5.8.9

3.3 – SYSTEM WATER REFERENCE VALUES

• pH: ………………………….. 6,5 ÷ 7,8
• Electrical conductivity: .. included between 250 and 800 µS/cm
• Total hardness: …………. included between 5 and 20 °F
• Total iron: …………………. lower than 0,2 ppm
• Manganese: ……………… lower than 0,05 ppm
• Chlorides: ………………… lower than 250 ppm
• Sulphur ions: ……………. absent
• Ammonia ions: ………….. absent

If total hardness is higher than 20°F or if some reference values of make-up water do not respect the indicated limits, please contact our pre-sale service to determine the treatments to be implemented.
Well or aquifer water not coming from an aqueduct must always be carefully analysed and, if necessary, treated with opportune treating systems. In case of installation of a softener, in addition to following the prescriptions of the manufacturer, adjust outlet water hardness not below 5°F (also carrying out pH and salinity tests) and check the concentration of outlet chlorides after resins regeneration.

In case water of the system is subject to dirtying phenomenons, such as the production of muds, the installation of an appropriate de-mudding system and an appropriate water treatment are required. The water of the system must always be maintained with the indicated reference values and must not show suspended substances. POSSIBLE ANOMALIES MAY COMPROMISE THE FUNCTIONALITIES OF THE MACHINE IRREVERSIBLY.
In case of danger of frost, empty the system and insert antifreeze liquid in a percentage compliant with the minimum reachable temperatures.
Water and ethylene glycol solutions used as heat carrier fluid in place of water cause a reduction of the unit performances. Add water with a maximum percentage of 35% of ethylene glycol (equal to a protection up to -20°C).

3.4 – HYDRAULIC SYSTEM FILLING
Once the hydraulic connections have been completed, it is necessary to proceed with filling of the system. Simultaneously, it is necessary to vent the air inside the pipes and of the appliance by beans of the air vents on the circuit and on the appliance.
Initially, with the water circuit empty, the machine must not be connected to the mains power supply.
The machine must be powered and the circulation pump started only in the final filling phases of the hydraulic circuit. It is advised to activate the temporary forcing function of the circulation pump for 15 minutes.
If an external auxiliary pump is used, the latter must also be started only in the final filling phases of the circuit.
The operating pressure of the system must not exceed 1,5 BAR when the pump is off.
In any case, to check for possible leaks of the system during test phase, it is advised to increase the test pressure (maximum pressure of 3 bar) and then to release it to reach operating pressure.

3.5 – CIRCULATION PUMP ALARM
If, during first start-up, error E06 appears on the display of the control panel after the start of the circulator E06:
a. Check that the valves of the system are open.
b. Check that at least one utility with circuit open is present.
c. Check that the external sieve filter is not clogged.
d. Check that there are no air pockets inside the circuit.
e. Check that water pressure of the system is correct.
f. Check that the circulator is not blocked.
To delete the pump alarm and restore operation, press the Reset icon on the display and confirm.

3.6 – ELECTRICAL CONNECTIONS
Before carrying out any intervention, make sure that all the power supplies are disconnected.

• These operations are only allowed for specialized personnel.

• Tightening of all the electrical connections has been performed correctly.
• The section of the power cables is suitable for the absorption of the appliance and for the length of the performed connection.
• Every object has been removed, in particular shavings, bits of wire and screws.
• Check that all cables are connected and that all electrical connections are solid.
• Both the service valve of the gas pipe and the one of the liquid pipe (fig. 14 – rif.34) are open.
• Ask the customer to be present at the operational testing.
• Show the contents of the instruction manual to the customer.
• Hand the instruction manual and the warranty certificate over to the customer.

4.2 – CHECKS DURING AND AFTER FIRST COMMISSIONING
Once start-up has been performed, check that:

• The current absorbed by the compressor is lower than the maximum one indicated in the plate data (see table in paragraph 3.6).
• During operation of the compressor, electrical voltage corresponds to the rated value +/-10%.
• The three-phase power supply has a maximum unbalance of 3% between the phases.
• The noise level of the three-phase compressor is not abnormal.
• The appliance works within the advised operating conditions (see paragraph “2.4”).
• The hydraulic circuit is completely de-aerated.
• The air-water heat pump stops and then reactivates.
• The difference between inlet water temperature and outlet water temperature of the conditioning system must be included between 4 and 7°C.
• If the difference between inlet water temperature and outlet water temperature should be lower than 4°C, set a lower speed of the circulator.
• If, on the contrary, it should be higher than 7°C, check for the opening of all the valves on the system and set, if possible, a higher speed of the circulator or insert an inertial accumulation (which acts as hydraulic separator) between the unit and the system and add an external pump which feeds the system.

Verification of outlet water temperature must be carried out when domestic water reaches the temperature set on the electronic control (set point reached).
Temperature must be checked annually to make sure that the valve adjustment is correct.

MANAGEMENT AND CONTROLS

6.1 – INTERNAL UNIT ADDITIONAL ELECTRIC HEATERS MANAGEMENT
The internal unit is equipped with two electric heaters. The electric heaters are enabled to integrate power in heating mode, domestic water production mode, during the execution of the Anti-Legionella cycles or for start-up of the system in case of low temperatures or in building sites for screed drying.
Parameter “ADDR217”
0 = not enabled
1 = one heater enabled for backup
2 = two heaters enabled for backup
3 = one heater enabled for low-temperature start
4 = two heaters enabled for low-temperature start

6.1.1 – Backup
The first electric heater EH1 activates if:

• The heat pump has been in heating mode or domestic hot water production mode for at least ADDR235 minutes.
• The external ambient temperature is lower than ADDR227 degrees Centigrade.
• The delta on water is at least 4°K with respect to the setpoint.

After further 15 minutes from the activation of the first electric heater, if these conditions persist, the second electric heater activates.
The backup function with electric heaters is not active if the external heat source ADDR226 is enabled (ON).

6.1.2 – Low-temperature start
The heaters intervene to ensure start-up even in conditions of low temperature of the hydraulic circuit water (conditions which occur occasionally as, for instance, before start-up of the system or when it is necessary to dry the screed).
Once the hydraulic circuit water reaches a temperature of approximately 12°C, the heaters switch off and normal operation of the heat pump is restored.

6.1.3 – Legionella prevention function
The Legionella prevention function is governed by the parameters from ADDR228 to ADDR233 and ADDR217.
The parameter ADDR229 differentiates three macro modes:
ADDR229=0
The Legionella prevention function is obtained by means of the combination of the main heat pump and of an optional electric heater (output K5).
The production of domestic hot water is managed with a temperature probe T3 ADDR228=2 and the Le- gionella prevention function is enabled (ADDR230>0), then the machine works as follows:

• It starts at the time ADDR231 and every ADDR230 days starts water heating until temperature ADDR232 is reached.
• When the machine reaches temperature ADDR232, it maintains it within 2°C for a time equal to ADDR233; if temperature ADDR232 is not reached within 7 hours from start-up, once 24 hours have elapsed, the machine tries again and the alarm E08 appears at the second failure.

ADDR229=1
The Legionella prevention function is obtained by means of the sole optional electric heater (output K5) and maintains the same modes described in the parameter ADDR229=0.
ADDR229=2
The Legionella prevention function is obtained by means of the two electric heaters EH1 EH2.
The production of domestic hot water is managed with a temperature probe T3 ADDR228=2 and the Legionella prevention function is enabled (ADDR230>0), then the machine works as follows:

• It starts at the time ADDR231 and every ADDR230 days stops any other heating or cooling function in progress using the sole electric heaters (to be enabled with parameter ADDR217).
• It maintains the same modes described in the parameter ADDR229=0.

Output K5 cannot be connected directly to the heater, add an external relay with appropriate electrical specifications.

6.2 – REMOTE CONTROL
It is possible to control some functions of the appliance remotely.
Parameter “ADDR220”
0 = remote control disabled
1 = remote control through serial
2 = remote control through free contacts

6.2.1 – Serial
The control from serial is only possible through SIOS CONTROL domotic.
If control from serial is enabled, some functions on the main screen are disabled (mode of operation, timer).

6.2.2 – Free contacts
The connections of the contacts must be carried out on the terminal box of the internal unit electronic board.
The contacts must be closed on terminal L. If control from contacts is enabled, some functions on the main screen are disabled (mode of operation).

domestic hot water production. If ADDR228=1, the production of domestic hot water is disabled with contact open, enabled with contact closed.
TA terminal| TA input can be connected to a free contact of a chronothermostat or to the contacts in parallel chiller/boiler of the electronic controls of the fan coils BI2 and BI2+. When the contact is closed, all cooling, heating and domestic water production functions are enabled. When the contact is open, only domestic water production remains active.
terminal 8| Input from SMART GRID or photovoltaic FTV1
terminal 9| Input from SMART GRID or photovoltaic FTV2

Relationship between mode of operation and the main contact inputs:

6.3 – ENERGY ACCUMULATION FUNCTIONS (PHOTOVOLTAIC AND SMART GRID)
The internal unit UI is equipped with two inputs to increase the accumulation of energy.
Parameter “ADDR341”
0 = disabled 1 = enabled 2 = Smart Grid abilitato

6.3.1 – Photovoltaic function
ADDR341 = 1
When one or both of the (EVU and SG) inputs are closed, it is possible to automatically force the accumulation of energy by requesting the internal unit to heat more (if in heating mode or in domestic water production) or to cool more (if in cooling mode).
Parameter “ADDR347” cooling water delta
Parameter “ADDR348” heating water delta
Parameter “ADDR349” domestic water delta

6.3.2 – Smart Grid function
ADDR341 = 2
It is possible to use the Smart Grid function through the parameter “ADDR341”; this function divides into 4 modes selectable through the opening and/or closure of the 2 contacts.
The different modes are explained below:

Normal operation:
The heat pump works normally.
Forced shutdown:
The heat pump switches off, autonomously, for a maximum of 2 hours during the day.
It is possible to display the switch-off time through the “Counters”.
The counter resets at midnight.
Mode 1:
In this mode the set point of the ACS is increased thus allowing to have a higher thermal energy stocked into the boiler.
Also works on the system water hysteresis on heating phase, cooling phase and on the ACS.
Mode 2:
In this mode the set point of the ACS is increased thus allowing to have a higher thermal energy stocked into the boiler.
In the same way, the set point is increased during heating phase, even without the request from the system terminals; the set point is decreased during cooling phase, even without the request from the system terminals.
Also works on the system water hysteresis on heating phase, cooling phase and on the ACS.

6.4 – CHECK OF THE CIRCULATION PUMPS
During installation, the operation of the circulation pump can be forced for 15 minutes from the window on the control display “Pumps”; in that way, air bleeding is eased in the final filling phase of water in the system. The circulation pump can work in different modes depending on the needs of the system:

• Continuous operation of the pump (parameter ADDR221=OFF=0)
• Switching off upon reaching the desired temperature (parameter ADDR221=ON=1) and sampling every ADDR237 minutes for one minute (parameter ADDR237=10 minutes, the pump will activate for one minute every ten minutes).

When the system is in stand-by or with fulfilled set point, the anti block function of the system and DHW circuit pumps is present; setting the parameter ADDR221=ON=1, the pump is activated every ADDR222 hours for a time equal to ADDR223 seconds).
The parameters above can be set in the window Service.

6.5 – AUXILIARY EXTERNAL HEAT SOURCE MANAGEMENT
In heating or domestic water production mode, set the parameter ADDR226=ON=1 and, if external ambient temperature is lower than ADDR227 degrees centigrade, the control will provide for the replacement of the heat pump with the activation of an output for enabling of an external heat source.

USE

7.1 – PRODUCTION OF DOMESTIC HOT WATER
During the production of domestic hot water with the main heat pump, the system produces as much power as possible to quickly meet the request for domestic hot water.
The request for domestic water can occur in the follow manners:

• Through DHW/L contact and setting parameter ADDR228=1; in this case, set the external thermostat at a temperature lower than 70°C.
• Through a temperature sensor inserted in the domestic hot water reservoir setting parameter ADDR228=2; in this case, the set point is determined by parameter ADDR210.

With parameter ADDR228=0, the production of domestic hot water is disabled.
With parameter ADDR238 it is possible to change the hysteresis cycle of the domestic water temperature check.
The temperature sensor T3 supplied in the internal module must always be inserted in and connected to the domestic hot water reservoir.

7.2 – ANTIFREEZE PROTECTIONS
The brazed plate exchanger of the main circuit and the evaporator of the heat pump for domestic hot water production at high temperature in the internal unit are protected against breaking in case of frost by a flow switch which stops the operation of the system when water flow rate is insufficient and by the temperature sensors on the exchanger.
7.3 – DEACTIVATION AND SWITCHING OFF FOR LONG PERIODS
To deactivate the heat pump, proceed as follows:

• Press the icon Stand by on the display.
• Cut off power to the external unit.

This way, the anti-blocking function of the circulation pump remains active.
The non-use of the heat pump for a long period of time entails that the following operations must be carried out:

• Press the icon Stand by on the display.
• Disconnect all power supplies of the internal unit through the main switches.
• Disconnect all power supplies of the external unit through the main switches.

To restart the air-water heat pump after a long period of inactivity of the heat pump, it is advised to rely on the Technical Assistance Service.

MAINTENANCE AND CLEANING

8.1 – CLEANING
Before proceeding with any maintenance and cleaning intervention, it is essential to disconnect all the power circuits and/or disconnect all the main switches.

• Cleaning of the sheet steel panels must be carried out only with cloths dampened with water and soap.
• In case of tenacious stains, damp the cloth with a 50% mixture of water and denatured alcohol or with specific products.
• Once cleaning is complete, dry the surfaces with care.

Do not use a chemically treated or antistatic cloth to clean the appliance.
Do not use gasoline, solvent, polish or similar solvents.
These products could cause the breakage or deformation of the plastic surface.

8.2 – PERIODIC MAINTENANCE
Periodic maintenance is essential in order to maintain the heat pump always efficient, safe and reliable over time. Maintenance can be carried out periodically by the Technical Assistance Service, which is technically authorized and prepared and also has, if necessary, original spare parts available.

The maintenance plan that OLIMPIA SPLENDID’s Technical Assistance Service or the maintenance technician must respect, with annual periodicity, includes the following operations and checks:

• Expansion vessels pressure check (check pressure on the label of the expansion vessel).
• Water circuit filling.
• Presence of air in the water circuit.
• Efficiency of safety devices.
• Electrical power voltage.
• Electrical absorption.
• Electrical connections tightening.
• Cleaning of fans grilles and external unit battery fins.
• Check for presence of dirt on the metallic net filters.
• Check of the sacrificial anode.

8.2.1 – Check of the domestic hot water reservoir magnesium anode
The magnesium anode is a sacrificial anode which depletes during the use of the domestic hot water reservoir.
The magnesium anode must be subject to visual check at least every two years (ref. standard DIN 4753).
The DHW reservoir of Sherpa Tower is equipped with a tester (fig.4 – rif.16) for check of the state of wear of the anode.
For wear check (fig.3-4):

• Remove the front panel (P) of Sherpa Tower
• Press the button located on the tester anode (D)

Check the position of the needle, if the needle of the tester positions in the green zone, it is not necessary to replace the magnesium anode.
If it positions in the red zone, it is necessary to replace the anode.
Proceed with the replacement of the anode as described below (Fig.4):
a. Undo the fixing nut (E) by releasing the terminal of the cable + of the tester anode with a 14mm wrench.
b. Unscrew the magnesium anode (C) with a 26mm wrench.
c. Insert the magnesium anode (C) in its seat by closing it hermetically during assembly with a suitable sealant (for example: hemp or PTFE tape) avoiding that the bar enters in contact with oil or grease.
Keep maximum cleaning during the operations inside the domestic hot water reservoir.
d. Check the seal of the reservoir during filling phase with water.
