3.2 Heat pump
Place the heat pump outdoors and away from any enclosed technical space. Choose a location that is preferably sunlit and sheltered from dominant winds. The device must be perfectly accessible for later installation and maintenance work. Placed under a shelter, the minimum required distances mentioned below must be respected in order to avoid any risk of air recirculation and a deficiency in the unit’s overall performance.

3. INSTALLATION AND CONNECTION (continued)
Do not position the device directly on the floor because this could cause problems. Favour positioning on the ground on anti-vibration studs. A wall bracket must not be used in conditions that can transmit vibrations. Do not install the heat pump on a support that risks intensifying the unit’s vibrations. Do not install the heat pump anywhere liable to amplify its noise level or anywhere where its noise could disturb neighbours. Do not use adhesives: the latter are not considered to be a reliable means of fastening.
Preferably, install the heat pump on a flat and dissociated cement block. Set up the unit on the supplied rubber bushing (fastenings and washers supplied). Fasten the device, in compliance with the tightening indicated to avoid any risk of accident or damage to equipment and persons. Another possibility: install the heat pump on rubber floor supports using suitable fastenings (not supplied).
5-7 N.m
x 4
The maximum installation distance between the unit and the swimming pool is 15 metres. The total length of the piping to and from the unit is 30 metres. Insulate both the above ground and buried hydraulic piping. The heat pump must be installed at a minimum distance from the pool in compliance with NF C 15-100 (3.5 m from the water for France) or in compliance with installation standards applicable in other countries. Do not install the heat pump close to a heat source. For installation in snowy regions we recommend sheltering the machine to avoid snow accumulating on the evaporator.

3. INSTALLATION AND CONNECTION (continued)
3.3 Hydraulic connection
The unit is supplied with two 50 mm Ø union connections. Connect the water inlet to the heat pump coming from the filtration group then connect the water outlet to the heat pump at the water conduit going to the pool (see diagram below).
Water outlet 50 mm Water inlet 50 mm
Install a by-pass valve between the heat pump entrance and exit. If an automatic distributor or an electrolyser is used, it should be installed imperatively after the heat pump with the goal of protecting the titanium condenser against an elevated concentration of chemicals. Be sure to install the by-pass valve and the supplied union connections at the water inlet and outlet level in order to simplify purging during the winter period and to facilitate access when disassembling for maintenance.

The cables sections are given for a maximum length of 25 m. They must however be checked and adjusted according to the installation conditions.
Always shut down the main power supply before opening the electrical control box.

3.5 Initial start-up

Start-up procedure – After installation is complete, follow these steps:

1. Rotate the fans by hand to verify that they can turn freely by hand, and that the turbine is correctly affixed to the motor shaft.

2. Ensure that the unit is connected correctly to the main power supply (see the wiring diagram in the appendix).

3. Activate the filtration pump.

4. Verify that all water valves are open and that the water flows toward the unit before switching on the heating or cooling mode.

5. Verify that the drainage hose is correctly affixed and that it causes no obstructions.

6. Activate the unit power supply, then press the On/Off button control panel.

on the

7. Ensure that no ALARM code is displayed when the unit is ON (see troubleshooting guide).

3. INSTALLATION AND CONNECTION (continued)
8) Set the water flow using the by-pass valve (see § 3.6 and 2.1), as provided for by each model, to obtain an Entry/Exit temperature of 2°C.
9) After running for several minutes, verify that the air exiting the unit is cool (between 5 and 10°).
10) With the unit operating, turn off the filter pump. The unit should automatically turn off and display error code E03.
11) Allow the unit and the pool pump to run 24 hours per day until the desired water temperature has been reached. When the set water inlet temperature is reached, the unit will turn off. It will automatically restart (as long as the pool pump is running) if the pool temperature is at least 0.5°C below the set temperature.
Water flow switch – The unit is equipped with a flow switch that turns on the heat pump when the pool filtration pump is running, and deactivates it when the filtration pump is out of order. If the water is low, the E03 alarm code will appear on the regulator (See § 6.4).
Time delay – The unit is equipped with a time delay of 3 minutes in order to protect the control circuit components, to eliminate restart cycling and contactor chatter. Thanks to this time delay, the unit automatically restarts approximately 3 minutes after each control circuit interruption. Even a brief power interruption will activate the restart time delay.
Phase switch – The Triphasic units include a phase switch to ensure that the compressor is rotating in the correct direction. If the unit does not start, check the condition of the phase switch located in the electrical box.

3. INSTALLATION AND CONNECTION (continued)
3.6 Water flow setting
With the water entry and exit valves being open, adjust the by-pass valve in order to obtain a difference of 2°C between the inflow and outflow temperature (see principle diagram § 3.1). You can verify the switch by seeing the entry/ exit temperatures directly on the control panel.

Water outlet temperature
Note: Opening the by-pass valve creates a weaker flow, which leads to an increase in T. Closing the by-pass valve creates a stronger flow, which leads to a decrease in T.

6.6 End of life of the device
The symbol of the crossed-out dustbin concerning the treatment and the reclamation of electrical and electronic waste means that the products must not be disposed of with household waste, bulky items or in a landfill under no circumstances. At the end of life, the device must undergo selective collection so that it can be recycled or reclaimed. A specific circuit for recovering this type of products is set up in the countries of the European Union and in Norway. Contact the installer or the local representative to have this device collected, dismantled and recycled. Retreating the refrigerant, oil and other parts has to be carried out by a qualified accredited professional in accordance with current local and national legislation. If the product contains batteries that bear this symbol, this means that the batteries can contain harmful or polluting substances.
