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).

Curve D circuit breaker
Cable section
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).
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.
7) Ensure that the alarm signal ( ) does not light up red.
If necessary see the troubleshooting guide (see § 6.4).
