• Incorrect installation and/or use may cause serious damage to property or serious injuries (possibly resulting in death).
• Any equipment, even carriage and packing paid, travels at the consignee's risk. The consignee should enter any reservations in
writing on the carrier’s delivery note, if there is any evidence of transport damage (and confirm them by recorded delivery letter
to the carrier within 48 hours). In the event of a device containing coolant fluid that has been tipped over, issue your reservations
to the carrier in writing.
• If the appliance suffers a malfunction, do not try to repair it yourself; contact a qualified technician.
• Refer to the warranty conditions for details of the permitted water balance values for operating the appliance.
• Eliminating or shunting one of the safety devices automatically voids the warranty, as does the replacement of parts using parts
not manufactured by ourselves.
• Do not spray insecticide or any other chemical (inflammable or non-inflammable) in the direction of the appliance, as this may
damage the body and cause a fire.
• Heat pump, filtration pump and filter appliances are compatible with all types of water treatment.
• Do not touch the fan and/or moving parts or insert a rod or your fingers in the vicinity of the moving parts while the appliance is
in operation. The moving parts may cause severe injury, including death.
• The electrical supply to the appliance must be protected by a dedicated 30 mA differential residual current protection device,
complying with the standards and regulations in force in the country where it is installed.
• Do not use an extension cord to plug the appliance into; plug it directly into a proper wall socket or outlet.
• Before carrying out any operations, check that:
- The voltage indicated on the maker's plate of the appliance corresponds to the mains voltage,
- The power grid is adapted to the power requirements of the appliance, and is properly grounded.
- The plug (where applicable) is suitable for the socket.
• In the event of abnormal function or the release of odours from the appliance, turn it of immediately, unplug it from its power
supply and contact a professional.
• Before any access to the appliance for any required service or maintenance, ensure that it is switched off and disconnected from

is deactivated.
• Do not disconnect and reconnect the appliance to the power supply when in operation.
• Do not pull on the power cord to disconnect it from the power supply.
• Do not attempt to carry out any service or maintenance with wet hands or while the appliance is wet.
• Clean the terminal board or the power supply socket before connection.
• For any component or sub-assembly containing a battery: do not recharge or dismantle the battery, or throw it into a fire. Do not
expose it to high temperatures or direct sunlight.
• In stormy weather, unplug the appliance to prevent it from suffering lightning damage.
• Do not immerse the appliance in water (with the exception of cleaners) or mud.
• Do not discharge R410A or R407C fluid into the atmosphere. These are fluorinated greenhouse effect gases, covered by the Kyoto
Protocol, with a Global Warming Potential (GWP) = 2088 for R410A (Directive EC 842/2006).
• According to French decree No. 2015-1790, if the appliance has more than 5teq CO2 of refrigerant gas (refer to manufacturer
specifications), the cooling circuit must be checked for leakage at least once a year. This operation must be carried out by a certified
cooling appliance specialist.
EN
The heat pumps comply with Directive 2014/68/EU (PED) via Annex III, Module D1, and certified as such by the third-party,
independent Notified Body, ICIM No. 0425.
Additional considerations in relation to this Directive
Installation and maintenance
The unit may not be installed close to combustible materials, or the air duct inlet of an adjacent building .
With some devices, it is essential to fit protection grids if the unit is installed in an area with uncontrolled access.
During installation, troubleshooting and maintenance, pipes may not be used as steps: the pipe could break under the weight, spilling
refrigerant and possibly causing serious burns.
When servicing the appliance, the composition and state of heat carrying fluid must be checked, as well as the absence of any
refrigerant.
During the annual unit sealing test in accordance with applicable legislation, the high and low pressure switches must be checked to
ensure that they are securely fastened to the coolant circuit and that they cut-off the electrical circuit when tripped.
During maintenance work, ensure there are no traces of corrosion or oil around cooling components.
Before beginning work on the cooling circuit, stop the device and wait for a few minutes before fitting the temperature and pressure
sensors. Some elements such as the compressor and piping may reach temperatures in excess of 100°C and high pressures with the
consequent risk of severe scalding.
Troubleshooting
All soldering work must be carried out by a someone qualified to do so.
Replacement pipes must always be made of copper in compliance with standard NF EN 12735-1.
Leak detection, pressure test:
- never use oxygen or dry air, risk of fire or explosion,
- use dry nitrogen or the mixture of nitrogen and refrigerant indicated on the information plate,
- the test pressure for both the high and low pressure circuits must not exceed 42 bar (for R410A) in the case the device is
equipped with the optional pressure gauge.
The high pressure circuit pipes are made of copper and have a diameter equal to or greater than 1’’5/8. A certificate as indicated in
§2.1 in compliance with standard NF EN 10204 will be requested from the supplier and filed in the facility's technical documentation.
Technical data relative to the safety requirements of the various applicable directives must be indicated on the information plate.
All this information must be recorded in the unit's installation manual, which must be kept in the technical file of the unit: model,
code, serial number, maximum and minimum OT, OP, year of manufacture, EC label, manufacturer’s address, refrigerant and weight,
electrical parameters, thermo-dynamic and acoustic performances.

❷ Use
2.1 I Operating principle
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.
Tip: improve your pool's temperature rise and maintenance
• Anticipate and plan the use of your pool well 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 an appropriate pool cover (bubble canopy, canvas, etc.) to prevent heat loss.
• Take advantage of a period with mild outdoor temperatures (on average > 10°C at night); it will be even
more effective if it runs 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).

❸ Maintenance
3.1 I Winterising
• Winterising is recommended if the device is not used for a long period.
• If only the heat pump is wintered, the device may be kept frost-free thanks to the resistances
on the condensers and the compressor(s); in this case, keep it powered with electricity. There
will be no need to drain the condensers.
• To avoid damaging the equipment due to condensation, do not fully cover it.
•
•
•
•
•
Disconnect the electrical 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 condensers (risk of freezing) by unscrewing the two water inlet and outlet connectors on
the back of the heat pump,
• In the case of full wintering for the pool (complete shutdown of the filtration system, bleed the filtration circuit or
even pool drainage): insert the two plugs provided and, where necessary, tighten the two connectors by one turn to
prevent any foreign body from penetrating the condenser,
• In the case of wintering for the heat pump only (shutdown of the heating only, but the filtration keeps running): do
not tighten the connectors but instead add 2 caps (provided) on the condensers water inlets and outlets.
3.2 I Servicing
• It is recommended that the equipment is fully serviced at least once a year to ensure proper
operation, maintain performance levels and possibly prevent potential failures.
• Depending on the legislation in the country where the device is installed, regular cooling
system checks may be required. Contact your technician.
• These operations are carried out at the user's expense and some must be carried out by a
qualified technician, as detailed below.
3.2.1 User maintenance
• Make sure that the ventilation grates are not blocked in any way.
• 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.
• 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 device; do not use any solvent-based products. Zodiac can provide you with a specific cleaning
kit as an option: the PAC NET, see § “5.1 I Description”.

Make sure that the electrical cables are correctly tightened and connected and that the electrical unit is clean.
❹ Troubleshooting
• Before you contact your reseller, please carry out these few simple checks using the following
tables if a problem occurs.
• If the problem continues contact your reseller.
•
: Actions only to be carried out by a qualified technician
4.1 I Device behaviour
The device does
not start heating
straight away
• On start-up, the device remains "paused" for 1 at 6 minutes before it starts operating; the
compressor number(s) flash.
• When the setpoint temperature is reached, the heat pump stops heating: the water
temperature.
• It may be that the heat pump has detected an operating fault (see § “4.2 I Displays”).
• If you have checked these points and the problem persists: contact your reseller.
The device is
draining water
• Often called condensation. 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
more damp the air, the more condensation your heat pump will produce (your device may
drain several litres of water per day).
• 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 condensation drains after half an hour, there is a water
leak in the heat pump; contact your reseller.
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 deice its evaporator, it will stop itself; this means that the
outdoor temperature is too low (below -12 °C).
The device is
"smoking"
• This may occur when it is in a defrost cycle and the water is converted to gas.
The device is not
