Condensation Connection
Condensation forms on the evaporator during cooling
operation because temperatures below the dew point
are reached. The collection tray of the indoor unit is
equipped with a condensation hose. The transport
height of the condensation pump is a max. of 250 mm
above the upper edge of the unit.
The condensation pump switches on after a brief delay
following the start of the unit. During cooling mode, it is
in continuous operation. After the unit is switched off,
the pump continues to run for approx. 7 minutes.
To ensure that the condensation can flow freely, the
condensation hose must be laid at an incline of at least
2 % to a drain or to the outside.
à
Hose extensions can be purchased as accessories.
à
If the condensation is being guided to a drainage
line, please install a siphon-like hose guideway which
acts as an odour seal.
à
To keep water from dripping, the condensation line
should be equipped with heat insulation.
à
If the unit is being operated at outside temperatures
below 0°C, the lines must be placed in such a way
that they are protected from frost.
à
If the drains or the collection trays are more than 250
mm from the mounted cassette, a second condensa-
tion pump purchased as an accessory should be
used.
à
After the hose has been laid, check to make sure
that condensation can drain freely.
Electric Connection
The electrical connections may only be made by author-
ised service personnel. Prior to installing the electrical
connections on the indoor unit, the system must be cur-
rent-free.
The electrical connections of the indoor unit and the ter-
minals of the control line to the outdoor part are located
on the regulating panel. The regulating panel is hidden
behind the grating on the indoor unit.
The complete unit control is located in the regulating
panel. The power supply is only connected to the out-
door part. The indoor unit is supplied with power from
the outdoor part via the control line.
1. Open the cover of the regulating panel by removing
the 3 screws and taking off the cover.
2. Guide the line through the edge protection rings on
the fresh air connections sides into the unit and lock
into place in the line clamp.
3. Begin wiring by connecting the protective conductor
and connect the contacts of the control, neutral and
external conductors.
