All equipment, even if shipped ‘free of carriage and packing’, is dispatched at the consignee’s own risk.
The person responsible for receiving the equipment must carry out a visual inspection to identify any dam-
age to the heat pump during transport (refrigerant system, body panels, electrical control box, frame). He/
she must note down on the carrier’s delivery note any remarks concerning damage caused during transport
and conrm them to the carrier by registered letter within 48 hours.
The equipment must always be stored and transported vertically on a pallet and in its original packaging. If
it is stored or transported horizontally, wait at least 24 hours before switching it on.
During installation and servicing
Only a qualied person may undertake installation, start-up, servicing and repairs, in compliance with
current standards.
Before operating or undertaking any work on the equipment (installation, commissioning, usage, servicing),
the person responsible must be aware of all the instructions in the heat pump’s installation manual as well
as the technical specications.
Under no circumstances install the equipment close to a source of heat, combustible materials or a build-
ing’s air intake.
If installation is not in a location with restricted access, a heat pump protective grille must be tted.
To avoid severe burns, do not walk on pipework during installation, repairs or maintenance.
To avoid severe burns, prior to any work on the refrigerant system, turn off the heat pump and wait several
minutes before placing temperature and pressure sensors.
Check the refrigerant level when servicing the heat pump.
Check that the high and low pressure switches are correctly connected to the refrigerant system and that
they turn off the electrical circuit if tripped during the equipment’s annual leakage inspection.
Check that there is no trace of corrosion or oil stains around the refrigerant components.
1.2 Safety instructions
1.1 General Terms of Delivery
WARNING : Please read carefully the safety instructions before using the equipment.
The following instructions are essential for safety so please strictly comply with them.
1. General

1.3 Water treatment
Poolex heat pumps for swimming pools can be used with all types of water treatment systems.
Nevertheless, it is essential that the treatment system (chlorine, pH, bromine and/or salt chlorinator meter-
ing pumps) is installed after the heat pump in the hydraulic circuit.
To avoid any deterioration to the heat pump, the water’s pH must be maintained between 6.9 and
8.0.
1. General
During use
To avoid serious injuries, never touch the fan when it is operating.
Keep the heat pump out of the reach of children to avoid serious injuries caused by the heat exchanger’s
blades.
Never start the equipment if there is no water in the pool or if the circulating pump is stopped.
Check the water ow rate every month and clean the lter if necessary.
During cleaning
Switch off the equipment’s electricity supply.
Close the water inlet and outlet valves.
Do not insert anything into the air or water intakes or outlets.
Do not rinse the equipment with water.
During repairs
Carry out work on the refrigerant system in accordance with current safety regulations.
Brazing should be performed by a qualied welder.
When replacing a defective refrigerant component, use only parts certied by our technical department.
When replacing pipework, only copper pipes conforming to Standard NF EN12735-1 may be used for
repairs.
When pressure-testing to detect leaks:
To avoid the risks of re or explosion, never use oxygen or dry air.
Use dehydrated nitrogen or a mixture of nitrogen and refrigerant.
The low and high side test pressure must not exceed 42 bar.

The heat pump should be located at least 2.5 meter away from the swimming pool.
Pool
3.1 Location
Please comply with the following rules concerning the choice of heat pump location.
1. The unit’s future location must be easily accessible for convenient operation and maintenance.
2. It must be installed on the ground, laid ideally on a level concrete oor. Ensure that the oor is sufciently
stable and can support the weight of the unit.
3. A water drainage device must be provided close to the unit in order to protect the area where it is installed.
4. Check that the unit is properly ventilated, that the air outlet is not facing the windows of neighboring
buildings and that the exhaust air cannot return. In addition, provide sufcient space around the unit for
servicing and maintenance operations.
5. The unit must not be installed in an area exposed to oil, ammable gases, corrosive products, sulfurous
compounds or close to high frequency equipment.
6. To prevent mud splashes, do not install the unit near a road or track.
7. To avoid causing nuisance to neighbors, make sure the unit is installed so that it is positioned towards the
area that is least sensitive to noise.
8. Keep the unit as much as possible out of the reach of children.
3. Installation
The heat pump is very easy to install, only water and power need to be connected during
installation.
Place nothing less than 1,50 m in front of the heat pump.
Leave 30 cm cm of empty space around the sides and rear of the heat pump.
Do not leave any obstacle above or in front of the unit!

3.3 Connecting the condensation draining kit
While operating, the heat pump is subject to condensation. This will result in a more or less large run-off
of water, depending on the degree of humidity. To channel this ow, we recommend that you install the
condensation drainage kit.
3. Installation
3.2 Installation layout
The lter located upstream of the heat pump must be regularly cleared so that the water in
the system is clean, thus avoiding the operational problems associated with dirt or clog-
ging in the lter.

3. Installation
The heat pump electrical plug integrates a 10mA differential circuit breaker.
Before connecting your heat pump, please ensure that the plug is connected to the ground.
The lter pump should function at the same time as the heat pump. Therefore, you need to connect them to
the same electrical circuit.

Useful information about how the heating mode operates
When the incoming water temperature is less than or equal to the required temperature (setpoint tempera-
ture) -X°C, the heat pump will switch to heating mode. The compressor will stop when the temperature of
the incoming water is greater than or equal to the required temperature (setpoint temperature).
Indicators for adjustment range X and Y
X : adjustable parameter from 1° to 15°C, default setting is 3°C. (Parameter N°6)
Step 1 : Press to switch on your pump.
Step 2 : Using buttons and select the required temperature.
EXAMPLE:

5. Operation
5.1 Operation
Conditions of use
For the heat pump to operate normally, the ambient air temperature must be between 7°C and 43°C.
Recommendations prior to start-up
Before activating the heat pump, please:
✔Check that the unit is stable.
✔Check that the gauge indicates a pressure greater than 80 psi.
✔Control the proper functioning of your electrical installation.
✔Check that the hydraulic connections are tight and that there is no leakage of water.
✔Remove any unnecessary object or tool from around the unit.
Operation
1. Connect the unit power plug.
2. Activate the circulating pump.
3. Activate the unit’s power supply protection (differential switch and circuit-breaker).
4. Activate the heat pump by pressing once on .
5. Select the required temperature.
6. The heat pump’s compressor will start up after a few moments.
All you have to do now is wait until the required temperature is reached.
WARNING: Under normal conditions, a suitable heat pump can heat the water in a swimming
pool by 1°C to 2°C per day. It is therefore quite normal to not feel any temperature difference in
the system when the heat pump is working.
A heated pool must be covered to avoid any loss of heat.
5. Operation
