Condensation connection
Because the temperature on the
register is below the dew point,
condensation is formed during
heating.
The lower housing cover on the
outdoor unit takes the form of a
collector. The condensation con- The condensation con-The condensation con-
nection supplied is to be fitted
here.
The on-site condensation pipe
must be laid with a gradient of
at least 2%.
If necessary, fit insulation that is
resistant to vapour diffusion.
When operating the unit at an
external temperature of less
than 0°C, the condensation
pipe must be laid with frost
protection. The customer must The customer mustThe customer must
keep the lower housing cover
free of frost to guarantee con-
stant drainage of the condensa-
tion. If necessary, auxiliary pipe
heating should be fitted.
After laying the pipes, free
drainage of the condensation
must be tested and permanent
impermeability ensured.
Electrical connection
The connections on the outdoor
unit are located inside the unit
above the connecting valves.
The conductor cross-section of
the power supply depends on the
structural conditions and the con-
nected load of the unit.
Connecting the outdoor unit
Before starting the connection,
observe the following instructions:
Connecting the RXW 350
wall unit
A power supply to the indoor unit
and a 5-wire control line from the
outdoor unit to the indoor unit
must be installed.
Connecting the RXW 480
wall unit
A power supply to the indoor unit
and a 6-wire control line from the
outdoor unit to the indoor unit
must be installed.
The power supply comes from
the connecting terminals on the
RXW indoor unit.
We recommend using a master
switch and a repair switch.
If the lines are installed in areas
with strong magnetic fields, the
control lines should be shielded.
The outdoor unit is actuated
by the connecting line from the
indoor unit.
The system is fused as set out
in the technical data.
Connecting the RXD
ceiling cassette
A power supply to the outdoor
unit and a 6-wire control line from
the outdoor unit to the indoor unit
must be installed.
The customer must install the
connecting box close to the
outdoor unit.
We recommend using a master
switch and a repair switch.
If the lines are installed in areas
with strong magnetic fields, the
control lines should be shielded.
The power supply to the indoor
unit comes from the connecting
