CONDENSATES
DRAINAGE
The
MD indoors unit
is equipped with a factory-fitted condensates lift pump
with a drainage lift height of 600 mm.
To ensure effective condensates drainage the downward slope should be 2 cm
per metre without any restrictions or rising pipe sections (See Fig. 1).
Moreover, a siphon with a height of at least 50 mm must be integrated in the
pipe to ensure that no unpleasant odours infiltrate the room.
To avoid condensation accumulating on the drainage pipe it must be insulated
with insulating material with a thickness of between 5 to 10 mm, such as
polyurethane, propylene or neoprene, in compliance with current regulations.
