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 floor-
standing 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 flex-
ible 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 con-
denser 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:
nAfter unpacking the unit let it sit on its transport
rollers for at least 5 minutes before you switch
it on.
nSet 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!
There must be a minimum clearance of 20 cm
between the rear of the unit and the wall.
nAll extensions to the power supply must be of a
sufficient cable size and must only be used
fully rolled out.
Fig. 6: Power supply
11

nCheck whether the stopper in the condensate
drain is present and correctly installed. There is
a risk of uncontrolled condensate leakage after
commissioning.

Fig. 8: Air inlet filter
1: Recirculated air filter
nEnsure 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.
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 neces-
sary to plug the exhaust air hose into the outlet
opening on the rear of the unit.
nEnsure 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. 9: Latch the hose into place
nThe exhaust air of the unit contains a certain
amount of moisture. For this reason it is advis-
able 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 dif-
ferent 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). Like-
wise the flat nozzle can be hung in a tilted window
(Fig. 11).
REMKO MKT
12

Via a wall pass-through
The hose supplied is firmly attached to a wall pass-
through. 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 per-
formance of the unit then arrange for the pres-
sure to be equalised (provide ventilation if nec-
essary on-site).

10 Shutdown
NOTICE!
Never switch off the equipment by pulling out
the mains plug.
Temporary shutdown
If it is planned to shut down the unit for longer
periods e.g. during the winter, proceed as follows:
1. Let the unit run in recirculating operation for
ca. 2 hours in order to dry the surfaces of the
evaporator fins. This will transport the
remaining moisture out of the unit and this
will avoid unpleasant odours when the unit is
re-commissioned.
2. Switch the unit off with the "POWER" key,
pull out the power plug and wind up the
power supply. Ensure that the wiring is not
kinked or too severely bent.
3. Place a suitable container underneath the
condensate drain of the internal reservoir.
The condensate drain is located on the lower
rear side of the unit.
4. Pull out the stopper from the condensate
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.
