Condensate drain on the exhaust air pipe
If M-WRG-II P ventilation units are used, a condensate drain should be provided. The
M-WRG-II LR 50-KA set, part no. 735200, with the following components may be used for
this purpose:
—
Outdoor air pipe, DN 100, 0.5 m (item 1 in Fig. 32)
—
Exhaust air pipe, DN 100, 0.5 m (item 2 in Fig. 32), with 1/2” male thread connection
(item 3 in Fig. 32) and barrier (item 4 in Fig. 32) for retaining the condensate
The condensate drain is not needed for M-WRG-II E units under the following conditions:
—
The ventilation unit is operated as described in “Intended use” (see section 2.5 on
page 9) and the “Rules for correct usage” chapter of the operating instructions.
— There is no exceptional loading due to very high atmospheric humidity.
NOTICE
Note the following points when creating the condensate connection:
— The condensate drain is to be created by the customer.
— Prevent odour transfer by installing an odour trap.
— If possible, connect the condensate drain to a grey water or rainwater discharge.
—
In cold regions, protect the condensate drain pipe (item 5 in Fig. 32) against frost,
e.g. by running it behind the facade insulation.
