Condensate drainage
connection
As the temperature on the heat
exchanger is below the dew point,
condensate is formed during
cooling mode.
Below the heat exchanger is a
collection tray which must be
connected to a drain.
■
The condensate drainage line
provided by the customer
should be installed with an
incline of at least 2 %. If
necessary, fit vapour-diffusion-
proof insulation.
■
Route the condensate drainage
line of the unit into the drain
line without any obstruction.
If the condensate runs directly
into a sewer pipe, fit a trap to
prevent any unpleasant odours.
■
When operating the unit at
outside temperatures below
0°C, ensure the condensate
drainage line is laid in such a
manner to protect it against
frost.
If necessary, fit a pipe heater.
■
Following installation, check
that the condensate drain is
unobstructed and ensure that
the line is permanently leak
tight.
Vertical mounting
The condensate drainage line
can be connected at the funnel
nozzle. The position of the nozzle
can be selected to be on the left
or right. The condensate drainage
connection of the condensate
tray which is not used must be
permanently sealed.
If a valve assembly is used, the
connection must be made to the
additional condensate tray.
Horizontal mounting
The condensate drainage line
can be connected directly to
the condensate tray. If a valve
assembly is used, the condensate is
conveyed to the unit's pan and is
drained from there.
The condensate drainage connection
of the condensate tray which is not
used must be permanently sealed
(a cap or similar).

Electrical wiring
All electrical installation work
is to be performed by specialist
companies. Disconnect the
power supply when connecting
the electrical terminals.
CAUTION
■
We recommend installing
a master / repair switch
provided by the customer close
to the indoor unit.
■
The power supply is made to
the indoor unit; a control line
to the chiller/heat pump is not
necessary.
■
If a condensate pump, which
is available as an accessory, is
used in conjunction with the
unit, the pump switching-off
contact switches off the power
supply or the valve if necessary.
■
The terminal block for making
the connections and the plug
are located behind the unit's
cover on the right side of the
unit.
Possible accessories
Room temperature controller
■
The room temperature controller
operates the unit. The controller
can be wall-mounted or
installed in the unit, as required.
Follow the separate Installation
Instructions.
Switch relay for 4 units, if appropriate
■
If several units are to be
controlled together in a group,
a switch relay is necessary if a
room temperature controller is
used.
Follow the separate Installation
Instructions.
Safety valve
Safety valves limit excess operating
pressure due to excess warming
or overfilling of the operating
medium. The valve outlet requires
unobstructed draining into a drain
line. Applicable local disposal
ordinances must be observed if
glycol is used.
No moisture can condense in
the nitrogen filler.
