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.
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 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 on the
control panel.
7) Make sure the alarm or lock symbols are not displayed. If need be, see
the trouble-shooting guide (see § 6.4).
3. INSTALLATION AND CONNECTION (continued)
Never use an electrical plug for the power supply.
The electrical power supply must have, in a suitable manner, an
omnipolar protection device of the D-curve circuit breaker type as well
as a 30mA protection differential circuit breaker (see following table).
Use an RO 2V/R 2V or equivalent power cord.
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.
After a cut-off of the power supply, wait 10 minutes before accessing
the active internal parts of the equipment (power stored in the
capacitors).

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 (See § 6.4).
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.
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.
3. INSTALLATION AND CONNECTION (continued)
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.
