Connection scheme for electric heater
In case of dehumidification wheel downstream of electric heater, it is ensured that control rotates
the wheel while electric heater is on (additional enabling contact).
7.5 Frost protection for plate heat exchanger
At low temperatures and high air speeds, the condensate in the plate heat exchanger can freeze
and cause its icing.
For devices supplied by EUROCLIMA with control, this is prevented by a pressure monitoring of the
plate heat exchanger and the temporary adjustment of the supply air volume flow.
7.6 Lighting
Depending on the number of delivered (optional) lamps, the assignment of the switches and junction
boxes can be found below:
1 Lamp
1 switch
> 1 <= 4 Lamp
1 switch, 1 junction box
> 4 <= 8 Lamp
1 switch, 2 junction box
> 8 <= 12 Lamp
1 switch, 3 junction box
The lamps are mounted and supplied with one side connected and one side loose cables, with a
sufficient length to be routed to the nearest junction box or the next switch.
The AHU will be delivered in parts, and for this reason the lights have to be connected on site in full
responsibility of the client.
If the AHU will be equipped on site with lights, it is to make sure that wet sections (and air down-
stream), such as

sections with condensate, such as cooling sections
Lighting with an at least protection of IP55 were used.
