Changing medium connection side
The connection side of the heat exchanger and the
condensate drainage line are installed at the fac-
tory on the left-hand side of the unit. It is possible
to change this to the right-hand side.
1.
Dismantle the condensate tray by removing
the four self-tapping screws from the tray
bracket
2.
Remove the screws from the heat exchanger
mounting on the side housing frame

3.
Pull the heat exchanger out of the unit's
mounting. Be careful as it is easy to be cut by
the fins. Do not bend any fins and do not
damage the insulation
4.
Cut the insulation of the side stay plate to
accommodate the brass connections on the
new connection side
5.
Feed the connections through the newly cre-
ated holes up to the stop

6.
Place the tear-resistant plastic film on the
pipe bend side between the stay plate insula-
tion and the heat exchanger mounting. The
film protects the insulation of the stay plate
against damage
7.
Let the heat exchanger slide into the retainer
(keep the same air duct) and after installing
the heat exchanger remove the film and
screw the unit back together in reverse order
Installation variants - Wall/ceiling unit for
installation between partition walls and ceilings
Installation on a wall:
The unit is secured to the wall by the unit housing.
The air inlet is, for example, at floor level or, for
example, via a duct elbow etc. The air outlet is
guided by a short duct system.
Installation beneath the ceiling:
The unit is secured beneath the ceiling or within
the suspended ceiling by the unit housing. The air
inlet is, for example, freely via a shadow gap on
the ceiling or e.g. via a duct angle, etc., the air
outlet is guided by a short duct system.
