❷ Use

  
2.1 I  Operating principle

2.1.1 General operation

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 conditions, your heat pump's power and 
the difference between the water temperature and the temperature you want. 
The warmer and damper the air, the better your heat pump will perform. The outdoor parameters for optimum operation 
are an air temperature of 27°C, a water temperature of 27°C and 80% relative humidity.

Tip: improve your pool's temperature rise and maintenance

•	 Anticipate the commissioning of your pool far enough in advance before you use it. 
•	 For the temperature rise, set the water circulation to continuous operation (24/24).
•	 To maintain the temperature throughout the season, run "automatic" circulation for at least 12 hours/
day (the longer this time the longer the heat pump will have enough operating 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 efficient 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 (adjusting the setpoint to maximum will not 
heat the water more quickly).
•	 Connect the "Heating priority"; the filtration pump and heat pump operating time will be set according 
to requirements.

2.1.2 Operating modes (default settings)

: External air temperature

: Heat pump shutdown, outside of operating range

: Forced "Boost" mode

: Possibility of selecting the "Boost" or "Silence" operating mode

: Forced "Silence" mode

* depending on model, see § «5.2 I Technical specifications» page 26.

2.1.3 Precautions

•	 Even though the appliance can be used all year round, certain precautions must be taken to 
avoid damaging the condenser (for the precautions specific to winterising, refer to § 3.1).
•	 If the heat pump is subjected to extended exposure to negative outdoor temperatures 
(excluding winterising period), you must:

	- Activate the ‘‘Heating Priority’’ option: the filtration 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 filtration pump is activated at least every 4 hours if the ‘‘Heating 

Priority’’ option is not activated on the heat pump.

❸ Maintenance

  
3.1 I  Winterizing

•	 Although the device may be used year around, in the event that it will not be used during the 
winter months, proper winterizing is necessary in order to prevent damage to the condenser. 
Damage due to failure to properly winterize the unit when it is not use is not covered by the 
warranty.
•	 To prevent condensation from damaging the appliance: cover the appliance with the 
winterising cover supplied (do not hermetically-seal the appliance inside a cover).

•	 Set the regulator to "standby" mode by pressing and holding 
 for 2 seconds and disconnect the power supply, 
•	 Open valve B,
•	 Close valves A and C and open valves D and E (if present), 
•	 Make sure that there is no water circulating in the heat pump, 
•	 Drain the water from the condenser (risk of freezing) by unscrewing the two water inlet and outlet connectors on the 
back of the heat pump, 
•	 In the case of full winterizing for the pool (complete shutdown of the filtration system, bleed the filtration circuit 
or even pool drainage): tighten the two connectors by one turn to prevent any foreign bodies from getting into the 
condenser, 
•	 In the case of winterizing for the heat pump only (shutdown of the heating only, the filtration keeps running): to not 
tighten the connectors but add 2 caps (provided) on the condenser's water inlets and outlets.
•	 We recommend that you put the aired winterizing micro cover (provided) on the heat pump.

  
3.2 I  Maintenance

•	 Before performing any maintenance operation on the appliance, you must cut the electricity 
supply as there is a risk of electric shock which may cause material damage, serious injury or 
even death.
•	 It is recommended that the appliance undergo general servicing at least on a yearly basis 
to ensure proper operation, maintain performance levels and potentially prevent certain 
failures. These operations are carried out at the user's expense by a qualified technician.

3.2.1 Safety instructions concerning appliances containing R32 refrigerant

Area check
•	 Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the 
risk of ignition is minimised.
Work procedure
•	 Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being 
present while the work is being performed.
General work area
•	 AIl maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. 
Work in confined spaces shall be avoided.

Check for the presence of refrigerant
•	 The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician 
is aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is 
suitable for use with all applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
Check for the presence of a fire extinguisher
•	 If any work involving heat is to be conducted on the refrigerating equipment or any associated parts, appropriate 
fire extinguishing equipment shall be available to hand. Have a dry powder or CO2, fire extinguisher adjacent to the 
charging area.
No source of ignition
•	 No person carrying out work in relation to a refrigerating system which involves exposing any pipe work shall use 
any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, 
including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and 
disposal, during which refrigerant can possibly be released to the surrounding space. Prior to work taking place, the 
area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. «No 
Smoking» signs shall be displayed.
Area ventilation

EN

16

Sayfa 19

•	 Prior to penetrating the unit in any way to perform any required service, ensure that the area is open and adequately 
ventilated. Proper ventilation, to allow for safe dispersion of any refrigerant which may be inadvertently released to 
the atmosphere, should be maintained while service is being performed on the unit.
Refrigeration equipment check
•	 The manufacturer’s service and maintenance guidelines must be followed at all times.  When replacing any electrical 
components, be sure to use only components which are of the same type and rating and which are recommended/
approved by the manufacturer.  If in doubt, consult the manufacturer’s technical department for assistance.
•	 The following checks shall be applied to installations using flammable refrigerants:
	- if an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
	- Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
	- refrigerating pipe or components are installed in a position where they are unlikely to be exposed to any substance 

which may corrode refrigerant containing components, unless the components are constructed of materials which 
are inherently resistant to being corroded or are suitably protected against being so corroded.
Electrical component check
•	 Repair and maintenance to electrical components shall include initial safety checks and component inspection 
procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit 
until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, 
an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties 
are advised.
•	 Initial 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 continuity 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 operating form of leak detection shall be located at the most critical point to 
warn of a potentially hazardous situation.
•	 Particular attention 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 protection is affected. This shall include damage to cables, excessive 
number of connections, terminals not made to original specification, damage to seals, incorrect fitting 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 
preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s 
specifications.
Repair of intrinsically safe components
•	 Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed 
the permissible voltage and current permitted for the equipment in use.
•	 Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable 
atmosphere. The test apparatus shall be at the correct rating.
•	 Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant 
in the atmosphere from a leak.
Wiring
•	 Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other 
adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from 
sources such as compressors or fans.
Detection of flammable refrigerant
•	 Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant 
leaks. A halide torch (or any other detector using a naked flame) shall not be used.
•	 The following leak detection methods are deemed acceptable for all refrigerant systems.
•	 Electronic leak detectors may be used to detect refrigerant leaks but, in the ease of flammable refrigerants, the 
sensitivity may not be adequate, or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-
tree area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak 
detection 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 confirmed.
•	 Leak detection fluids 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/extinguished.
•	 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 off 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 - conventional procedures shall 
be used. However, for flammable refrigerants it is important that best practice is followed since flammability Is a 
consideration. The following procedure shall be adhered to:

	- remove refrigerant;
	- purge the circuit with inert gas (optional for A2L);

17

Sayfa 20

	- evacuate (optional for A2L);
	- purge with inert gas (optional for A2L);
	- open the circuit by cutting or brazing.
•	 The refrigerant charge shall be recovered into the correct recovery cylinders. For appliances containing flammable 
refrigerants other than A2L refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance 
safe for flammable refrigerants. This process may need to be repeated several times. 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 potential ignition sources and that ventilation is 
available.
•	 In addition to conventional charging procedures, the following requirements shall be followed.
	- Ensure that contamination of different 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 position according to the instructions.
	- Ensure that the refrigerating 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 overfill the refrigerating system.
•	 Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak-
tested on completion 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 essential that the technician is completely familiar with the equipment and 
all its detail. It is recommended good practice 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 essential that electrical power is available before the task is commenced.
1.	Become familiar with the equipment and its operation.
2.	Isolate system electrically.
3.	Before attempting the procedure, ensure that:
	- mechanical handling equipment is available. if required. for handling refrigerant cylinders;
	- all personal protective equipment is available and being used correctly:
	- the recovery process is supervised at all times 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 instructions.
8.	Do not overfill 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 filled correctly and the process completed, make sure that the cylinders and the 
equipment are removed from site promptly and alt isolation valves on the equipment are closed off.
11.	Recovered refrigerant shall not be charged into another refrigerating system unless it has been cleaned and checked.

3.2.2 User maintenance

•	 Make sure that the ventilation grid is not blocked by any foreign bodies.
•	 Clean the evaporator (for location see § ‘’5.3 I  Dimensions and marking’’) using a soft 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 impurities 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 specific «PAC NET» cleaning kit is available as an 
accessory in the Zodiac catalogue for this purpose (see § ‘’5.1 I  Description’’).

3.2.3 Maintenance to be carried out by a qualified technician

❹ Troubleshooting

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

•	
: Actions to be performed by a qualified technician only

  
4.1 I  Appliance behaviour

•	 When the setpoint temperature is reached, the heat pump stops heating: the water temperature 
is higher than or equal to the setpoint temperature.
•	 When the water flow rate is zero or is not enough, the heat pump stops: check that the water is 
circulating correctly in the heat pump (see § ‘’2.2 I  User interface presentation’’) and that the 
hydraulic connections are correct.
•	 The heat pump stops when the outdoor temperature falls below -12 °C.
•	 It may be that the heat pump has detected an operating fault (see § ‘’4.2 I  Error code display’’). 
•	 If you have checked these points and the problem persists: contact your retailer.

The appliance 
does not start 
heating straight 
away

•	 Often 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 connections’’). 
•	 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 filtration pump for the water to circulate in the heat pump. If 
the water continues to flow through the condensate drainage lines, there is a water leak in the 
heat pump; contact your retailer.

The appliance 
is discharging 
water 

•	 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 evaporator is 
iced over

•	 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 off and disconnect the 
heat pump immediately and contact your retailer.

The appliance is 
"smoking"

•	
 If there is no display, check the supply voltage and the F2 fuse.
•	 When the setpoint temperature is reached, the heat pump stops heating: the water temperature 
is higher than or equal to the setpoint temperature.
•	 When the water flow rate is zero or is not enough, the heat pump stops: check that the water is 
circulating correctly in the heat pump (see § ‘’2.2 I  User interface presentation’’).
•	 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 operating fault (see § ‘’4.2 I  Error code display’’). 

The appliance is 
not working

•	 Check that the automatic water filling controller (see diagram in § «2.3 I Operation») is not 
stuck in the open position: 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 Installation’’).

The appliance 
is working 
but the water 
temperature 
does not increase

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

•	 If the outdoor temperature is low, the heat pump performs defrost cycles under normal 
operation.
•	 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 section used is 
appropriate (see § ‘’5.2 I  Technical specifications’’).

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