5
C. IMPORTANT SAFETY INSTRUCTIONS
 Always place the unit on an even, level surface.
 An opening in a window (in portable version only) or wall is required to
accommodate the exhaust hose to expel the hot air.
 Ensure the unit is connected to an earthed power supply of the correct
rating. (Refer to the rating label located at the back of the unit).
 The unit will cool when the room temperature is between 18°C~32°C
depending on the thermostat setting.
 DO NOT use this unit for functions other than those described in this
instruction manual.
 DO NOT tilt the unit.
 DO NOT cover or obstruct the appliance’s inlet and outlet grilles.
 Your air conditioner has been designed to be used only in the home, office
and similar conditions and should not be used for any other purpose.
 This unit is for indoor use only.
 Never unplug the air conditioner while it is working, this could damage the
electronic circuits.
 DO NOT use the appliance in a wet room, such as a bathroom or laundry
room to avoid the risk of electrical shocks.
 DO NOT bend or crush the warm air exhaust hose. (in portable version
only)
 DO NOT sit or place articles on the appliance.
 DO NOT use the appliance with wet or damp hands.
 DO NOT let chemical substances come into contact with the appliance.
 DO NOT use the appliance in the presence of flammable substances or
vapours such as alcohol, insecticides, petrol, etc.
 DO NOT use the plug to start and stop the appliance. ALWAYS use the
intended control panel to start and stop the unit.
 ALWAYS turn off the appliance when it is not in use and remove the mains
plug from the socket outlet.
 ALWAYS turn the unit off and remove the mains plug before cleaning,
carrying out maintenance or moving location.
 Do not pull the electrical cable or place it near a source of heat: always
unroll it completely to avoid dangerous overheating. If the power cord
becomes damaged, the service agent or a similarly qualified person must
replace it, in order to avoid a hazard.
 The filter must be used with the product at all times, when removing it for
clearing always turn the unit off and unplug the mains plug from the
socket.
 Do not operate the unit with a damaged power cord or plug, after it
malfunctions, has been dropped or damaged. If the power cord is
damaged it must be replaced by the manufacturer or a qualified service
engineer to avoid a hazard.
 Closely supervise any children and pets when unit is in use

6
Energy Saving Tips
 Blocking of the filter reduces the efficiency of the air and increases its
power consumption by up to 6%.
 Avoid opening doors frequently.
 Each person present in a room provides between 100 Watts and 150
Watts of heat. Consequently, the more people there are in a room, the less
effective the unit will be in cooling.
 To ensure the optimal efficiency of the unit, we advise you to keep doors
and windows closed, and to take into account the surface of the walls and
windows exposed to the sun.
 Avoid the use of adapter plugs, multiple sockets and /or extension leads. If
their use is necessary, ensure they conform to current safety standards.
 Before starting the appliance, check that it is correctly earthed, according
the legislation in force in the country concerned.

BROWN - LIVE
GREEN AND YELLOW - EARTH
As the colours of the wires in the mains lead of this appliance may not
correspond with the coloured markings identifying the terminals in your plug,
proceed as follows:
1. The BLUE wire is the NEUTRAL and must be connected to the terminal,
which is marked with the letter Nor coloured BLACK.
2. The BROWN wire is the LIVE and must be connected to the terminal, which
is marked with the letter Lor coloured RED.
3. The GREEN/YELLOW is the EARTH and must be connected to the
terminal which is marked with the letter Eor or coloured GREEN OR
GREEN/YELLOW.
4. Always ensure that the cord grip is positioned and fastened correctly.

F. WALL MOUNTING INSTALLATION INSTRUCTIONS
1. Positioning the air conditioner
 To obtain maximum performance
from your unit, it must be
correctly positioned. Please
following the guidelines and
instructions below in full, as
failure to do so could cause
potential installation problems:
 The air conditioner must be
installed on an exterior wall that
has access to the outside and a
minimum of 2 meters free
clearance to allow good airflow
 The unit must be fitted
following the template, with
space to the top, bottom and
sides of the unit.
 The wall on which the unit is
installed must be sturdy and able to withstand the weight of the unit.
After determining the best place for installation as described above,
please check to ensure that the wall can be drilled without causing
damage to the fabric of the building. If necessary obtain professional
advice to ensure that no damage is done to power supply or water pipes.
Please also ensure that there are no obstacles on the outside of the wall
which may interfere with the performance of the unit.

2. Template
Fasten the template to the wall once the following guidelines have been
thoroughly checked.
 Do not drill any holes until you are 100% confident that there are no
obstacles in the area you wish to drill and there are no obstructions, which
could be hidden by the construction of the wall, for example: Electrical
wiring, water &gas pipes or supporting lintels or beams.
 Ensure that a spirit level is used, as the unit must be level.
 Follow the installation instructions & measurements in full.

12
3. Drilling the Wall
Please note: If you are drilling the hole above ground floor level, please
ensure that the outside area is supervised until drilling has been
completed.
INTAKE AND OUTLET HOLES
 This operation should be
carried out using the proper
tools (diamond tip or core bit
drills with high twisting torque
and adjustable rotation speed)
 Fasten the template to the wall
taking care to check the
distance from the floor and or
ceiling and keep horizontal by
using a spirit level.
 Use a pilot drill to mark the
centre of each core hole to be drilled. Use a core boring head having a
diameter of 135mm to drill the two holes for intake and outlet air
 It is recommended that the holes must have a slight downward inclination of
3-5 degrees to prevent any backflow of water from the pipes.
Drainage
The unit produces condensate that has to be extracted to enable the unit to
operate correctly. It is necessary to drill a hole through the wall measuring
30mm in diameter in the position shown in the template. Drainage occurs by
gravity. For this season, it is essential for the drain line to have a minimum
downward inclination of at least 3% throughout its length.
3. Fastening the bracket
 Drill the holes for
anchoring the fastening
bracket to the wall using
the 6 holes showed in
black on the template. If
the wall is not sturdy
enough it is advisable to use extra anchor bolts using the holes showed in
grey on the template
 The anchor bolts provided require 8mm holes; the wall should be inspected
to determine if provided bolts are sufficient. No liability can bee accepted by
the manufacturer or his agent in case of underestimation of the structural
consistency of the anchorage made at the time of installation.

13
4. Installation of vent tubes
 After drilling the holes, the plastic pipes supplied with the air conditioner
need to be fitted through them.
 The pipe with a diameter 130mm (hot air discharge) has to be fitted in the
right hole. The length of the pipes should be matches to the thickness of the
wall..
 Fit the plastic pipe into the hole and fasten the flange with 2* M4 screws on
the wall. Please use the same instructions to fit the left hand tube (air intake
pipe) using the supplied pipe with a diameter of 120mm.
 The tube diameter is slightly smaller than that carried out using the 135mm
nominal diameter core drill. Please centre the pipe into the hole in the wall
and insulate and seal using polyurethane foam to prevent air and humidity
penetration.
 Fit the drainage pipe into the pre-drilled hole and seal as above. A further
extension pipe can be fitted if necessary.
5. Remove the screws on the filter
Please remove the 2 screws before
fastening the unit on the bracket.

14
6. Fitting the unit on bracket
After checking again that the fastening bracket is securely fastened to the wall,
and that any necessary preparations for electric connection and condensate
drainage have been made, tilt the unit slightly towards you to aid the operation
of fastening the unit onto the bracket. Fit the drainage pipe that protrudes from
the l back of the unit, which is then inserted in the drainage hole.
The air conditioner can now be pushed firmly against the wall. Carefully inspect
the installation to ensure that the insulating back panel fits firmly against the
wall and there are no gaps at the back of the air conditioner.
