m
Danger to life!
The unit must be fully isolated from the mains power supply before all maintenance and installation work and
opening the terminal compartment!
Danger of electric shock, moving parts (fan) and hot surfaces .
m
Risk of injury due to high unit weight!
Heat exchangers are very heavy and can contain condensate water.
Two people are required for dismantling the unit (AIR1 RH 1500, 2000).
