INSTALLATION
Location of the mobile air conditioner
Remove the mobile air conditioner from the packaging and make sure you
have removed all parts and accessories. We recommend that two adults
remove the air conditioner from the packaging.
Locate the mobile air conditioner on an even, dry and stable surface and
within reach of agrounded power socket. Do not locate it on unstable or
inclined surface from which the mobile air conditioner could slide, fall,
become damaged or cause injury.
The mobile air conditioner must be located so that it is not exposed to the
direct sunshine.
Make sure there are no heat sources (e.g., heating, portable heaters, stove,
etc.) near where the mobile air conditioner will be located.
For easier handling, the mobile air conditioner is equipped with castors.
Do not use the castors when you need to move the air conditioner over
carpets or similar surfaces. Avoid riding over objects.

computer servers, etc. are located. Installation, adjustment,
maintenance and repairs must only be performed by
aqualified person.
Installing the flexible hose on to the mobile air conditioner
The flexible hose must be connected to the mobile air conditioner and
installed into awindow in accordance with the operating modes that
you wish to set. Install the flexible hose when you wish to select the
operating modes: cooling, heating, dehumidification, or sleep mode. It
is not necessary to install the flexible hose when you wish to select the
fan mode.
1. Extend the flexible hose to the required length.
2. Attach the adapter for connection to air outlet to one end of the
flexible hose and screw counter clockwise. Attach the window
connection adapter to the other end of the flexible hose and screw
counter clockwise – see the figure F1.
3. Place the flexible hose above the air outlet and move it downwards
to fix it – see the figure F2.
Do not excessively bend or deform the flexible hose.

sliding windows (vertical and horizontal). Nevertheless, for certain types
of slide windows it may be necessary to modify the installation procedure
described below.
1. Slide the panel Ainto the panel B to the window width/length – see
the figure G1. It is important that the holes in the top part of the
window insert are aligned.
2. Make sure the dimension is correct and there are no gaps or air
pockets.
3. Insert ascrew into the hole in the top part of the window insert and
tighten it – see the figure G2. This ensures that the panels will not
move.
4. Open the slide window and place the window insert into the space.
5. Carefully close the slide window. Hold the window insert with one
hand to keep it in the place.
6. Install the flexible hose with the attached adapter into the hole in the

CONDENSATE DRAINAGE
The mobile air conditioner is equipped with two drain outlets where
each draining condensate from adifferent part of the air conditioner. In
the case of afrequent use of the mobile air conditioner, it is necessary to
regularly check the quantity of condensate and drain it. If you choose the
dehumidification mode, we recommend draining the condensate using
adrain hose that you connect to the upper drain hole.
Note:
In cooling and fan operating mode (provided low humidity
in the room), it may not be necessary to drain the
condensate. The mobile air conditioner is designed to
increase the efficiency with asmall amount of water in the
condensate tank.
Condensate drainage from the bottom drain hole
When the water level in the tank reaches the preset level, the operation
of the mobile air conditioner will stop, abeep will sound, and the display
will show “Ft” (full tank). To drain the condensate from the air conditioner,
proceed as follows:
1. Disconnect the power plug from the power socket.
2. Carefully re-locate the mobile air conditioner to alocation where the
water may be drained.
3. Underneath the drain outlet, place acontainer into which the
condensate will flow. Carefully remove the plug of the drain outlet–
see the figure H1. Connect the drain hose – see the figure H2;
and allow the condensate to flow out. You may tilt the mobile air
conditioner slightly backwards while draining the condensate.
4. Once the water tank is empty (condensate has stopped flowing),
disconnect the drain hose and put the plug back into the drain
outlet. Before turning on the mobile air conditioner again, make
sure that plug of the drain outlet is correctly inserted, and seals will.
Otherwise, condensate could leak during the operation, and it could
damage the floor or carpet.
5. Insert the power plug into apower socket and turn on the mobile air
conditioner.
Condensate drainage from the top drain hole
The top drain hole is used for continuous draining.
1. Disconnect the power plug from the power socket.
2. Remove the plug of the drain outlet – see the figure H3. Connect
the drain hose – see the figure H4. If the length of the drain hose
is insufficient, then it is necessary to purchase alonger hose of
the same type. Never extend the length of the drain hose using
extensions.
3. Connect the end of the drain hose to the waste water drain.
4. Insert the power plug into apower socket and turn on the mobile air
conditioner.
Note:
The drain hose should be installed at the same height or
lower than the top drain outlet – see the figures H5 and
H6. Otherwise, the condensate will not be properly drained
from the water tank.

COMPRESSOR PROTECTION
The compressor is equipped with time protection against damage when it is
switched on again, lasting 3minutes. If the mobile air conditioner is switched
on shortly after it has been switched off, the compressor will only start
running after 3minutes.
