VENTILATION THE RIGHT WAY
V E N T I L A T I O N & H E A T R E C O V E R Y
2.2.3 Installation in wet areas
The following rules from DIN VDE 0100-701/702 (IEC 60364-7-701) apply to installation
of M-WRG-II ventilation units in wet areas:
— Protection zone 0: The unit must NOT be installed in this area.
— Protection zone 1: The unit must only be installed with the “integrated into wall” U
2
variant. The extract and supply air valves must be installed in the top part of the wall
or in the ceiling.
— Protection zone 2 and other zone: The unit may be installed in this area.
Country-specific standards/regulations on observing the protection zones for installation
in rooms with bathtub or shower must also be followed.
2.2.4 Condensate drain
The heat recovery process in our ventilation units causes condensation. This condensa-
tion is dissipated via the exhaust air pipe.
— If M-WRG-II P ventilation units are used, a condensate connection should be provided
(see section 8.14 on page 33).
—
With M-WRG-II E ventilation units (with enthalpy heat exchanger) there is no conden
-
sation if the following requirements are fulfilled:
—
The ventilation unit is operated as described in “Intended use” (see section 2.5 on
page 10) and the “Rules for correct usage” chapter of the operating instructions.
— There is no exceptional loading due to very high atmospheric humidity.
2.2.5 Starting and using the ventilation unit
— Do not start up the ventilation unit until it is fully installed.
— Always make sure that the cover is closed and locked in place before using the venti-
lation unit.
— Please note that the ventilation unit must not be used without the outer wall terminal
for safety reasons.
