2.1 I Operang principle

2.1.1 General operaon

Your heat pump uses the calories (heat) in the air to heat up your pool's water. The process to heat your pool's water to the temperature you want may take a few days as it depends on the weather condions, your heat pump's power and the dierence between the water temperature and the temperature you want. The warmer and damper the air, the beer your heat pump will perform. The outdoor parameters for opmum operaon are an air temperature of 27°C, a water temperature of 27°C and 80% relave humidity. Tip: improve your pool's temperature rise and maintenance

• Ancipate the commissioning of your pool far enough in advance before you use it.

• For the temperature rise, set the water circulaon to connuous operaon (24/24).

• To maintain the temperature throughout the season, run "automac" circulaon for at least 12 hours/ day (the longer this me the longer the heat pump will have enough operang range to heat up).

• Cover the pool with a sheet (bubble canopy, canvas, etc.) to prevent heat loss.

• The heat pump will be even more ecient if it operates during the warmest hours of the day.

• Keep the evaporator clean.

• Set the temperature you want and let the heat pump run (adjusng the setpoint to maximum will not heat the water more quickly).

• Connect the "Heang priority"; the ltraon pump and heat pump operang me will be set according to requirements.

2.1.2 Operang modes (default sengs)

: External air temperature : Heat pump shutdown, outside of operang range : Forced "Boost" mode : Possibility of selecng the "Boost" or "Silence" operang mode : Forced "Silence" mode

• Even though the appliance can be used all year round, certain precauons must be taken to avoid damaging the condenser (for the precauons specic to winterising, refer to § 3.1).

• If the heat pump is subjected to extended exposure to negave outdoor temperatures (excluding winterising period), you must: - Acvate the ‘‘Heang Priority’’ opon: the ltraon pump will operate while the pool’s temperature is below the heat pump’s setpoint temperature. If the setpoint is reached, the pump will operate for 5 minutes every 2 hours. - Make sure that the pool’s ltraon pump is acvated at least every 4 hours if the ‘‘Heang Priority’’ opon is not acvated on the heat pump.12

Electrical component check

• Repair and maintenance to electrical components shall include inial safety checks and component inspecon procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit unl it is sasfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to connue operaon, an adequate temporary soluon shall be used. This shall be reported to the owner of the equipment so all pares are advised.

• Inial safety checks shall include: - that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking; - that no live electrical components and wiring are exposed while charging, recovering or purging the system; - that there is connuity of earth bonding. Repair of insulated components

• During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operang form of leak detecon shall be located at the most crical point to warn of a potenally hazardous situaon.

• Parcular aenon shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protecon is aected. This shall include damage to cables, excessive number of connecons, terminals not made to original specicaon, damage to seals, incorrect ng of glands, etc.

• Ensure that the apparatus is mounted securely.

• Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose of prevenng the ingress of ammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specicaons. Repair of intrinsically safe components

• Do not apply any permanent inducve or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permied for the equipment in use.

• Intrinsically safe components are the only types that can be worked on while live in the presence of a ammable atmosphere. The test apparatus shall be at the correct rang.

• Replace components only with parts specied by the manufacturer. Other parts may result in the ignion of refrigerant in the atmosphere from a leak. Wiring

• Check that cabling will not be subject to wear, corrosion, excessive pressure, vibraon, sharp edges or any other adverse environmental eects. The check shall also take into account the eects of aging or connual vibraon from sources such as compressors or fans. Detecon of ammable refrigerant

• Under no circumstances shall potenal sources of ignion be used in the searching for or detecon of refrigerant leaks. A halide torch (or any other detector using a naked ame) shall not be used.

• The following leak detecon methods are deemed acceptable for all refrigerant systems.

• Electronic leak detectors may be used to detect refrigerant leaks but, in the ease of ammable refrigerants, the sensivity may not be adequate, or may need re-calibraon. (Detecon equipment shall be calibrated in a refrigerant- tree area.) Ensure that the detector is not a potenal source of ignion and is suitable for the refrigerant used. Leak detecon equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed, and the appropriate percentage of gas (25% maximum} is conrmed.

• Leak detecon uids are also suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.

• If a leak is suspected, all naked names shall be removed/exnguished.

• If a leakage of refrigerant is found which requires brazing. all of the refrigerant shall be recovered from the system. or isolated (by means of shut o valves} in a part of the system remote from the leak. Removal and discharge

• When breaking into the refrigerant circuit to make repairs - or for any other purpose - convenonal procedures shall be used. However, for ammable refrigerants it is important that best pracce is followed since ammability Is a consideraon. The following procedure shall be adhered to: - remove refrigerant; - purge the circuit with inert gas (oponal for A2L);18 - evacuate (oponal for A2L); - purge with inert gas (oponal for A2L); - open the circuit by cung or brazing.

• The refrigerant charge shall be recovered into the correct recovery cylinders. For appliances containing ammable refrigerants other than A2L refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance safe for ammable refrigerants. This process may need to be repeated several mes. Compressed air or oxygen shall not be used for purging refrigerant systems. Loading procedures

• Ensure that the outlet tor the vacuum pump is not close to any potenal ignion sources and that venlaon is available.

• In addion to convenonal charging procedures, the following requirements shall be followed. - Ensure that contaminaon of dierent refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them. - Cylinders shall be kept in an appropriate posion according to the instrucons. - Ensure that the refrigerang system is earthed prior to charging the system with refrigerant. - Label the system when charging is complete (if not already). - Extreme care shall be taken not to overll the refrigerang system.

• Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak- tested on compleon of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site. Dismantling

• Before carrying out this procedure, it is essenal that the technician is completely familiar with the equipment and all its detail. It is recommended good pracce that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of recovered refrigerant. It is essenal that electrical power is available before the task is commenced.

1. Become familiar with the equipment and its operaon.

2. Isolate system electrically.

3. Before aempng the procedure, ensure that:

- mechanical handling equipment is available. if required. for handling refrigerant cylinders; - all personal protecve equipment is available and being used correctly: - the recovery process is supervised at all mes by a competent person; - recovery equipment and cylinders conform to the appropriate standards.

4. Pump down refrigerant system, if possible.

5. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system

6. Make sure that cylinder is situated on the scales before recovery takes place.

7. Start the recovery machine and operate in accordance with instrucons.

8. Do not overll cylinders (no more than 80 % volume liquid charge).

9. Do not exceed the maximum working pressure of the cylinder, even temporarily.

10. When the cylinders have been lled correctly and the process completed, make sure that the cylinders and the

equipment are removed from site promptly and alt isolaon valves on the equipment are closed o.

11. Recovered refrigerant shall not be charged into another refrigerang system unless it has been cleaned and checked.

3.2.2 User maintenance

• Make sure that the venlaon grid is not blocked by any foreign bodies.

• Clean the evaporator (for locaon see § ‘’5.3 I Dimensions and marking’’) using a so brush and a fresh water spray (disconnect the power cable); do not fold over the metal wings, then clean the condensate drainage line to remove any impuries that may be blocking it.

• Do not use a high pressure jet. Do not spray with rain water, salt water or water which is full of minerals.

• Clean the outside of the appliance using a solvent-free product; a specic «PAC NET» cleaning kit is available as an accessory in the Zodiac catalogue for this purpose (see § ‘’5.1 I Descripon’’).

3.2.3 Maintenance to be carried out by a qualied technician

• Please read the safety instrucons before performing any of the maintenance operaons described below, see ‘’3.2.1 Safety instrucons concerning appliances containing R32 refrigerant’’

• Check that the control system is operang correctly.

• Check that the condensates ow correctly when the appliance is in operaon.

• Check the safety mechanisms.

• Check the connecon of the metal masses to the earth.

• Check that the electrical cables are correctly ghtened and connected and that the switch box is clean. EN19 ❹ Troubleshoong

• If a problem occurs, before you contact your retailer, please carry out these few simple checks using the following tables.

: Acons to be performed by a qualied technician only

4.1 I Appliance behaviour

The appliance does not start heang straight away

• When the setpoint temperature is reached, the heat pump stops heang: the water temperature is higher than or equal to the setpoint temperature.

• When the water ow rate is zero or is not enough, the heat pump stops: check that the water is circulang correctly in the heat pump (see § ‘’2.2 I User interface presentaon’’) and that the hydraulic connecons are correct.

• The heat pump stops when the outdoor temperature falls below -12 °C.

• It may be that the heat pump has detected an operang fault (see § ‘’4.2 I Error code display’’).

• If you have checked these points and the problem persists: contact your retailer. The appliance is discharging water

• Oen called condensates. This water is the moisture contained in the air which condenses on contact with certain cold mechanisms in the heat pump, especially on the evaporator. The damper the air, the more condensates your heat pump will produce (your appliance may drain several litres of water per day). This water is retrieved by the base of the heat pump and drained by the condensate drainage elbow (see § ‘’1.2 I Hydraulic connecons’’).

• To check that the water is not coming from a leak in the pool circuit on the heat pump, shut down the heat pump and run the ltraon pump for the water to circulate in the heat pump. If the water connues to ow through the condensate drainage lines, there is a water leak in the heat pump; contact your retailer. The evaporator is iced over

• Your heat pump will soon switch to its defrost cycle to melt the ice.

• If your heat pump cannot manage to defrost its evaporator, it will stop itself; this means that the outdoor temperature is too low (below -12 °C). The appliance is "smoking"

• The machine has come to the end of the defrost cycle; water has changed to gaseous state and passes through the grid.

• If your heat pump is not in its defrost cycle, this is not normal. Switch o and disconnect the heat pump immediately and contact your retailer. The appliance is not working

If there is no display, check the supply voltage and the F2 fuse.

• When the setpoint temperature is reached, the heat pump stops heang: the water temperature is higher than or equal to the setpoint temperature.

• When the water ow rate is zero or is not enough, the heat pump stops: check that the water is circulang correctly in the heat pump (see § ‘’2.2 I User interface presentaon’’).

• The heat pump stops when the outdoor temperature falls below -12 °C or rises above +40 °C.

• It may be that the heat pump has detected an operang fault (see § ‘’4.2 I Error code display’’). The appliance is working but the water temperature does not increase

• Check that the automac water lling controller (see diagram in § «2.3 I Operaon») is not stuck in the open posion: this will keep supplying cold water into the pool and will prevent the temperature from rising.

• There is too much heat loss. Install a heat insulated cover on your pool.

• The heat pump is unable to capture enough calories as its evaporator is clogged with dirt. Clean it to restore its performances (see § ‘’3.2 I Maintenance’’).

• Check that the external environment is not hindering the heat pump (see § ‘’❶ Installaon’’).

Check that the heat pump is the right size for this pool and its environment. The fan is running but the compressor stops from me to me with no error message

• If the outdoor temperature is low, the heat pump performs defrost cycles under normal operaon.

• The heat pump is unable to capture enough calories as its evaporator is clogged with dirt. Clean it to restore its performances (see § ‘’3.2 I Maintenance’’). The appliance trips the circuit breaker

Check that the circuit breaker is correctly dimensioned and that the cable secon used is appropriate (see § ‘’5.2 I Technical specicaons’’).

The supply voltage is too low: contact your electricity supplier.20
