Equipment description
The device is particularly suited for flexible operation, but can also be mounted in a stationary installation. The local air conditioning unit is comprised
of an indoor unit for setting up on the floor indoors
and an outdoor unit for wall or ground installation
outdoors. In "cooling" mode, the output produced
by the compressor precisely matches itself to
requirements, and thereby regulates the nominal
temperature with minimal temperature deviations.
This "inverter-technology" results in energy savings
over conventional split systems and also reduces
noise emissions to a particularly low level. The
flexible connection pipe serves to transport the
heat outdoors. The outdoor unit discharges the
absorbed heat to the outdoor air by means of a
heat exchanger (condenser). The condensate collected during cooling operation is transported to
the outdoor unit by means of a condensate pump
integrated into the indoor unit and evaporates via
the heat exchanger. The device filters and dehumidifies the air and thereby creates a comfortable
room climate. It works fully automatically and offers
numerous additional options thanks to its microprocessor control system. The device can be conveniently operated by means of the infrared remote
control unit included.

The connecting line is connected to the indoor unit
with quick-release couplings. This provides the
facility to disconnect the connecting line from the
indoor unit for assembly purposes without losing
refrigerant.
Connecting line
DANGER!
The unit must be disconnected from the mains
supply during the entire process! It may only be
switched back on when all of the connections
have been made and checked. The fastenings
and all of the covers must be attached beforehand.
DANGER!
Suitable protective gear must be worn when
connecting or disconnecting the connection
pipe.
Instructions for disconnecting the connecting
line:
n Disconnect the units only immediately before
assembly and only leave the units disconnected for as long as is absolutely necessary.
n Before the pipes are reconnected, it is to be
ensured that there is no dirt, moisture or other
foreign bodies in the quick release couplings
which could impair their function.
n Always mount the cable strap as soon as the
pipelines are connected.
n The pipelines may only be disconnected and
connected by authorised specialist engineers.
NOTICE!
The escape of refrigerant contributes to climatic change. In the event of escape, refrigerant with a low greenhouse potential has a
lesser impact on global warming than those
with a high greenhouse potential. This device
contains refrigerant with a greenhouse potential of 1975. That means the escape of 1 kg of
this refrigerant has an effect on global warming
that is 1975 times greater than 1 kg CO2,
based on 100 years. Do not conduct any work
on the refrigerant circuit or dismantle the
device - always enlist the help of qualified
experts.
