3 Design and function
Unit description
The local air conditioning unit is particularly well
suited to flexible use.
The local room air conditioner comprises a floorstanding unit for the indoor area and an exhaust air
hose to conduct the heat away. The indoor unit
extracts the heat from the room to be cooled by
means of an evaporator (heat exchanger) and
transfers it to the internal cooling cycle. This
releases the heat back to the outside via another
heat exchanger (condenser) by means of the flexible exhaust air hose.
The condensate arising during cooling mode is
continually drained off via the condenser by means
of a condensate pump located in the unit - the condenser evaporates the condensate and discharges
it to the outside via the exhaust air hose.
The unit filters and dehumidifies the air thereby
creating a comfortable room climate. It works fully
automatically and offers numerous additional
options thanks to its microprocessor controller. The
unit can be conveniently operated by means of the
infrared remote controller included.

5 Assembly and
installation
Assembly and unit installation instructions
The unit is positioned at the desired location with
the discharge side pointing into the room. When
positioning, observe the following instructions:
n After unpacking the unit let it sit on its transport
rollers for at least 5 minutes before you switch
it on.
n Set the unit down in a stable position on a level
and firm floor. If the floor is uneven then this
can lead to vibrations and disturbing noises.
Fig. 5: Unit installation
NOTICE!
You will achieve a pleasant room temperature
if you set the desired target temperature max.
4 to 7 °C below the outside temperature.
Help save on energy consumption in stand-by
mode! If the device, system or component is
not in use, we recommend disconnecting the
power supply. Components with a safety function is excluded from our recommendation!
NOTICE!
There must be a minimum clearance of 20 cm
between the rear of the unit and the wall.
n All extensions to the power supply must be of a
sufficient cable size and must only be used
fully rolled out.

n Check whether the stopper in the condensate
drain is present and correctly installed. There is
a risk of uncontrolled condensate leakage after
commissioning.
Fig. 7: Condensate drain
1: Condensate drainage with stopper
n Never operate the unit without the air inlet filter.
Otherwise, the fins of the heat exchanger can
become dirty and the unit loses performance.
Conduct the warm exhaust air away
NOTICE!
The exhaust air hose should always be laid
rising in the direction of air flow and must not
be extended!
In cooling mode the unit creates warm moist
exhaust air, which must be conducted away from
the room to be cooled. For this reason it is necessary to plug the exhaust air hose into the outlet
opening on the rear of the unit.
n Ensure that the catches for the exhaust air
hose latch securely into the two openings of
the connection aperture. In order to be sure of
effective operation, do not lay the flexible
exhaust air hose with tight bends and do not
kink it and to prevent damage resulting to avoid
air carrying components!
Fig. 8: Air inlet filter
1: Recirculated air filter
n Ensure that persons and sensitive objects,
such as plants, are not placed directly in the air
flow emerging from the unit.
In addition, with direct solar radiation close the
curtains and blinds and keep the windows and
doors closed during operation.
Fig. 9: Latch the hose into place
n The exhaust air of the unit contains a certain
amount of moisture. For this reason it is advisable to feed the exhaust air to the outdoor area
or to outdoors.
Exhaust air routing variants
You can route the exhaust air out of the building as
follows:
Via a flat nozzle
The flat nozzle supplied can be used in various different ways. It is possible to feed the flat nozzle
through an open window and fasten it by means of
Velcro and a window suction cup (Fig. 10). Likewise the flat nozzle can be hung in a tilted window
(Fig. 11).
12
Via a wall pass-through
The hose supplied is firmly attached to a wall passthrough. A suitable wall pass-through is available
as an accessory (Fig. 12
Fig. 10: Exhaust air with open window
).
Fig. 11: Exhaust air with tilted window
Fig. 12: Wall pass-though
NOTICE!
In some circumstances routing the exhaust air
via a firmly attached exhaust air hose, e.g.
through closed doors or windows, can lead to
negative pressure in the room in which the unit
is being used. If this should reduce the performance of the unit then arrange for the pressure to be equalised (provide ventilation if necessary on-site).

drain and collect the condensate that drains
out.
5. Then insert the stopper once again. A
missing stopper or an incorrectly inserted
stopper will result in condensate leaking out
after re-commissioning.
6. Store the unit in an upright position in a cool,
dry and dust-free location protected from
direct sunlight. Cover the unit with a synthetic
cover to protect it against dust if desired.
Permanent shutdown
The entire system should only be dismantled by a
specialist firm familiar with all environmental
aspects involved. REMKO GmbH & Co. KG or your
sales partner will be pleased to provide details of
refrigerant specialists in your area.
