10 Slope of the condensation line
at least
2% slope
The condensation hose is designed
to be installed on the left side
(viewed from the front).
All electrical installation
work is to be performed
by specialty companies.
Disconnect the voltage supply
when connecting the electrical
terminals.
ATTENTION
Monitoring for leaks
Once all the connections have
been established, the pressure
gauge station is attached as
follows to the Schrader valve (if
fitted):
red = small valve
= injection pressure
blue = large valve
= suction pressure
Once connected, perform a leak
test using dry nitrogen.
The tightness test involves
spraying a leak detection spray
onto the connections. If bubbles
are visible, the connections have
not been properly made. Tighten
the connection or prepare a new
flange.
If the leak test is successful,
depressurise the refrigerant lines
and start a vacuum pump with an
absolute final partial pressure of
min. 10 mbar to create a vacuum
in the lines. Any moisture present
in the pipes will also be removed.
A vacuum of min. 20 mbar
must be created!
ATTENTION
The time required to generate
the vacuum is dependent on the
pipework volume
of the indoor unit and the length
of the refrigerant lines. The
process will always take at least
60 minutes
.
Once any foreign gases and
moisture have been completely
extracted from the system, the
valves on the pressure gauge
station will be closed and the
valves on the outdoor component
will be opened as described in the
chapter on "Commissioning".
Condensate connection
Due to undercutting of the
dew point at the vaporiser,
condensation forms during
cooling
and in the condenser
duringheating.
Below the vaporiser is a collection
tray, which must be connected to
a drain.
The lower section of the outdoor
component's housing is designed
to serve as a collection tray. The
condensate connection included
in the scope of delivery is to be
attached here.
■
The condensation line is to
be installed with a minimum
slope of 2 %. (figure 10).
If necessary, fit vapour diffusion
tight insulation.
■
Lead the condensation line
freely to the run-off line. 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
+4 °C, make sure to route
the condensation to prevent
freezing. The lower part of the
housing is also to be kept frost
free by the user, in order to
ensure permanent draining of
the condensate.
If necessary, fit supplementary
pipe heating.
■
After completed installation,
check for unobstructed
condensation run off and
ensure that a permanent seal is
provided.
Electrical connection
A mains cable must be installed as
voltage supply to the Indoor unit
and a control cable to the outdoor
unit, with appropriate safeguards.
■
We recommend that a mains/
repair switch be installed near
the outdoor component.
■
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.
■
Control cables should be
screened if laid in areas exposed
to strong magnetic fields.
■
Electrical protection
is provided in accordance with
the technical data.
