6. Environmental conditions and
operating limits
● Maximum permitted temperature of the air
40 °C.
● The domestic air supply must be set up so
that virtually no air can flow into the living
areas from the kitchen, bathroom and WC.
● A room from which the air has to be ex-
tracted must be fitted with a non-closable,
free supply air cross section of at least
150 cm²,
e.g. with Maico door ventilation
grille MLK.
● VZ, F, KVZ and KF units: Resistance to
interference according to EN 55014-2
depending on pulse shape and energy
component 1000 to 4000 V. If operating
with fluorescent tubes, extra interference
suppression measures are needed (L or
C components or RC modules, protection
diodes, varistors) because these values
may be exceeded.
● Storage: Store unit exclusively in a dry
location (-20 to +50 °C).

8.1 Wall
The prescribed minimum distances
between the wall and the ceiling
shown in figure A must be observed.
1. Make sure the housing has a level base.
2. Fit wall breakthrough or drill core hole.
Minimum diameter, 120 mm.
Recommendation: Fit wall sleeve
WH 120. Fit wall breakthrough with
minimum diameter 136 mm.
3. Lay the power cable as shown in Fig. A up
to place of installation (surface-mounted
AP or recessed-mounted UP). Observe
spacing. Observe ducting length within
the housing.
