Connection to electricity supply

The air-conditioning unit must be wired by a trained, qualified electrician in
accordance with the applicable regulations (VDE, local power utility, etc.).
If the intake fan or discharge fan is switched off or fails, all control valves
must close automatically and the hot-water/cold-water and washer pumps
must shut down.
Install only control valves which are closed when de-energized and a frost-
protection thermostat without restart disabler.
Install a lockable repair switch for each drive motor to ensure that the air-
conditioning unit can be reliably shut down.
Completion of the electrical wiring work must be followed by a safety inspection
of the installation in accordance with VDE 0701 Part 1 and VDE 0700 Part 500 or
comparable national safety codes.
Caution Use only electric motors designed to drive fans.
Always comply with the wiring diagram in the terminal box.
Use a thermistor-type trigger for a motor with PTC thermistor, an interlock
contactor for a motor with thermo-contacts, or a thermal overcurrent relay for a
motor without PTC thermistor or therm-contacts.
