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)
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).
Install a by-pass valve between the heat pump entrance and exit.
of the filter Ø 50 ENTRY H2O
to the pool Ø 50 EXIT H2O
It is advised to install the unit on a dissociated cement block or a
mounting bracket designed for this use and to set up the unit on the
supplied rubber bushing (fastenings and washers not supplied).
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.
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.

3.5 Initial start-up
Start-up procedure - After installation is complete, follow these steps:
1) Rotate the fan by hand to verify that it can turn freely, 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 on the
control panel.
7) Ensure that no ALARM code is displayed when the unit is ON (see
troubleshooting guide).
3. INSTALLATION AND CONNECTION (continued)
The electrical power supply must have, when appropriate, a fuse
protection device like a feed motor (aM) or D curve circuit breaker as
well as a differential circuit breaker 30mA (see following table).
Always shut down the main power supply before opening the electrical
control box.

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.

3.6 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.

5. MAINTENANCE AND WINTERISING
5.1 Maintenance
These maintenance operations must be carried out once per year in order to
guarantee the longevity and the good working condition of the heat pump.
• Clean the coil with the help of a soft brush or jet of air or water (Warning,
never use a high pressure cleaner).
• Verify that the drains flow well.
• Verify the tightening of the hydraulic and electrical connections
• Verify the hydraulic sealing of the condenser.
Before any maintenance operation, the heating pump must be
disconnected from any electrical current source. The maintenance
operations must only be carried out by personnel that is qualified and
authorised to handle liquid refrigerants.
Any damage caused by poor winterising maintenance will lead to
cancellation of the warranty.
5.2 Winterising
• Put the heat pump in “OFF” mode.
• Cut the power supply to the heat pump.
• Empty the condenser with the help of the drain to avoid any risk of
deterioration. (high risk of freezing).
• Close the by-pass valve and unscrew the entry/exit connection unions.
• Eliminate the maximum amount of residual stagnant water from the
condenser with the help of an air gun.
• Close the water entry and exit areas of the heating pump to avoid
introducing foreign bodies.
• Cover the heating pump with a dedicated winterising case.
