General

1.1 General Terms of Delivery
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 damage 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 confirm 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.
1.2 Safety instructions
WARNING : Please read carefully the safety instructions before using the equipment.
The following instructions are essential for safety so please strictly comply with them.
During installation and servicing
Only a qualified 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 specifications.
Under no circumstances install the equipment close to a source of heat, combustible materials or a building’s air intake.
If installation is not in a location with restricted access, a heat pump protective grille must be fitted.
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.
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 flow rate every month and clean the filter 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 qualified welder.
When replacing a defective refrigerant component, use only parts certified 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 fire 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.
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 metering 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.

Installation

The heat pump is very easy to install, only water and power need to be connected during installation.
3.1 Location
The heat pump should be located at least 2.5 meter away from the swimming pool. 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 floor. Ensure that the floor is sufficiently stable and can support the weight of the unit.

3. 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 sufficient space around the unit for servicing and maintenance operations.

4. The unit must not be installed in an area exposed to oil, flammable gases, corrosive products, sulfurous compounds or close to high frequency equipment.

5. To prevent mud splashes, do not install the unit near a road or track.

6. 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.

7. Keep the unit as much as possible out of the reach of children.

Place nothing less than 1,50 m in front of the heat pump.
Leave 30 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!
3.2 Installation layout The filter 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 clogging in the filter.
3.3 Hydraulic connection Step 1
Screw the connectors to the heat pump
Step 2
Connect the water outlet pipe and the water intake pipe
3.4 Electrical connection
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 filter pump should function at the same time as the heat pump. Therefore, you need to connect them to the same electrical circuit.

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.
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.

Maintenance and servicing

6.1 Maintenance, servicing and winter storage
WARNING: Before undertaking maintenance work on the unit, ensure that you have disconnected the electrical power supply.
Cleaning
The heat pump’s casing must be cleaned with a damp cloth. The use of detergents or other household products could damage the surface of the casing and affect its properties.
The evaporator at the rear of the heat pump must be carefully cleaned with a vacuum cleaner and soft brush attachment.
Annual maintenance
The following operations must be undertaken by a qualified person at least once a year.”
Carry out safety checks.
Check the integrity of the electrical wiring.
Check the earthing connections.
Monitor the state of the pressure gauge and the presence of refrigerant.
Winter storage
Your heat pump is designed to operate in rainy weather conditions and withstand frost using a specially created anti-frost technology. However it is not recommended to leave it outside for long periods of time (eg over winter). After draining down the pool for the winter, store the heat pump in a dry place.

Repairs

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.
7.1 Breakdowns and faults
