REMKO RXW 261 - Manual (Page 19)

Condensation connection
Due to the dew point shortfall,
condensation forms on the
vaporiser during the cooling
operation on the indoor unit.
Below the vaporiser is a collection
tray, which must be connected to
a drain.
■
The condensation pipe should
have a fall of min. 2 %. (Fig. 5).
If necessary, fit vapour diffusion
proof insulation.
■
The condensation pipe from
the unit should run freely
into the drainage pipe. If the
condensation runs directly into
a sewer pipe, install a trap to
prevent any unpleasant odors.
■
When operating the unit at
outdoor temperatures below
+4 °C, ensure the condensation
pipe is laid to protect it against
frost. If necessary, install a pipe
heater.
■
After completed routing, check
for unobstructed condensation
discharge and ensure that
a permanent seal is provided.
The condensation hose is designed
to be installed on the left side
(view from front).
Electrical connection
A protected power supply cable
and asix-core (RXS) or a 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
■
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.
Make the connection as follows:
1. Open the air intake grill.
2. Unfasten the cover on the right
side and at the bottom right
rear. (Fig. 6).
3. Connect the unit to the
control cable from the outdoor
component. See electrical
connection diagram. For series
RXW 681 IT, the terminal block
for the power supply as well
as for the control contacts is
behind the front cover.
4. Re-assemble the unit.
■
We recommend to install
a main / repair switch on the
building near the indoor unit.
■
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.
