Condensation
connection
If the temperature falls below the
dew point, condensation will form
on the cooling fins during cooling
mode.
A collection tray together with
a condensation pump and float
switch are fitted as standard below
the cooling fins. Should the float
switch trip a protective shutdown
due to inadequate removal of
the condensation, the pump will
switch on immediately and run on
for approx. three minutes.
■ The condensation pipe should
have a fall of min. 2 %.
This is the responsibility of
the customer. If necessary,
fit vapour diffusion tight
insulation.
■ If the level of the condensation
pipe on the unit is above
that of the outlet, route the
pipe vertically upwards (max.
1000 mm from the bottom
edge of the unit) and then with
a fall to the drain.
■ The condensation pipe from
the unit should run freely
into the drainage pipe. If the

condensation runs directly
into a sewer pipe, fit a trap to
prevent any unpleasant odours.
■ When operating the unit at
outdoor temperatures below
0 °C, ensure the condensation
pipe is laid to protect it against
frost.
If necessary, fit supplementary
pipe heating.
■ Once the pipe has been laid,
check the condensation drains
off and permanently seal it.
Electrical connection
A protected mains supply cable
and six-core (RXS) or four-core
(RXM) control cable should
be connected to the outdoor
component and indoor unit
respectively.
All electrical installation
work should be performed
by specialist contractors.
Isolate the voltage supply
when connecting the electrical
terminals.
CAUTION
■
We recommend that customers
install a main/repair switch
in the vicinity of the outdoor
component.
■
The terminal blocks for making
the connections are located at
the rear of the unit. When the
unit is installed, measurements
can be made from the front by
removing the cover.
■
If an optional condensation
pump is used in conjunction
with the unit, it may be
necessary to install an
additional relay with a higher
contact rating after the switch-
off contact on the pump to
switch off the compressor.
