4.4 Connecting the condensate drain
The unit must be fitted with a condensate drain.
The condensate drain must be fitted as indicated in the drawings. The condensate drain outlets not in use must remain sealed. The
condensate drain line must include a trap and lead into a sanitary sewer. The trap must be permanently primed with water. After the
unit has been out of operation and then re-commissioned, the trap musts be checked for priming and unobstructed passage. The
condensate drain line must be connected in such a way so that handling the unit does not cause its damage. Before opening the
door of an RB5 ceiling-suspended unit, the condensate drain line(s) must be disconnected.
Everything is described in detail in a separate manual – Condensate drain installation.
General condensate drain arrangement in DUPLEX R5 units
The condensate drain line must include a trap and lead into a sanitary sewer. The trap must be permanently primed with water.
After the unit has been out of operation and then re-commissioned, the trap musts be checked for priming and unobstructed
passage. The dimension of the condensate drain line connection in all DUPLEX R5 units is 2× Ø16/Ø22.
