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).
Models

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.
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.
