10 Incline of the condensate line
minimum
2% incline
The condensate hose is designed
to be connected on the left-hand
side (as viewed from the front).
All electrical installation
work should be performed
by specialist contractors.
Disconnect the power supply
when connecting the electrical
terminals.
! ATTENTION
Leak testing
Pumping down to
vacuum
Once all the connections have
been made, the pressure gauge
station is attached to the Schrader
valve as follows (if fitted):
red = small valve
= injection pressure
blue = large valve
= suction pressure
Following connection of the quick-
release couplings, the connections
are checked using leak detection
spray and suitable devices for leak-
tightness. If leaks are found, the
connections have not been made
properly. Tighten the connection
or, if necessary, remove the quick-
release coupling and check for
contamination or damage.
A vacuum of min. 20 mbar
must be created!
! ATTENTION
The time required to generate the
vacuum is dependent on the
pipe volume of the indoor unit
and the length of the refrigerant
pipes. This always takes at least
60 minutes
.
Once any foreign gases and
humidity have been completely
extracted from the system, the
valves on the pressure gauge
station are closed and the valves
on the outdoor component
are opened as described in the
"Commissioning" section.
Electrical connection
A mains cable must be installed
as voltage supply and a control
cable to the indoor unit. The air
conditioning unit should be fused
in accordance with the technical
data. The pre-installed control
cable on the indoor unit must be
laid to the outdoor component.
■
We recommend installing
a main / repair switch on the
building close to the indoor
unit.
■
If an optionally available
condensation pump is used
on the unit, then an additional
relay for the shut-off contact
of the pump will be needed
to increase the switching power
to shut off the compressor.
Both units are pre-filled with
refrigerant. Pumping down to
vacuum is not required before
first commissioning.
! ATTENTION
Condensate draining and
ensured discharge
Condensate connection
If the temperature falls below the
dew point, condensation will form
on the finned condenser during
heating operation.
A condensate drip pan should be
installed on the underside of the
unit to drain any condensate.
■ The condensate drain pipe to
be installed on-site must be in-
stalled with a in cline of at least
2 % for good drainage.
If necessary, fit vapour density
insulation.
■ When operating the system at
outdoor temperatures below
4 °C, care must be taken that
the condensate line is frost
protected. The lower part of the
housing and condensate pan
are to be kept frost free in order
to ensure permanent drainage
of the condensate.
If necessary, fit supplementary
pipe heating.
■ After completed installation,
check that the condensate
drainage is unobstructed and
ensure that the line is leak tight.
Ensured discharge in the event of
leakage
Local regulations or environmen-
tal laws, for example the German
Water Resource Law (WHG), can
require suitable precautions to pro-
tect against uncontrolled draining
in case of leakage to provide for
safe disposal of escaping refrigera-
tor oil or hazardous media.
