7.2. How to Operate
Fig. 1
(1) Open the Control Panel Cover.
Fig. 2
(2) Power Supply
Switch off the breaker and set the Main Control Knob to the
OFF position before plugging the power plug into an
electrical outlet.
Fig. 3
(3) Main Control Knob
Set to LOW COOLING or HIGH COOLING and LOW
HEATING or HIGH HEATING as desired. (FAN setting
operates the fan only.)
Caution: If the Main Control Knob is turned off or
changed to a fan setting from a cooling operation
setting,WAIT at least 3 minutes before resetting to
cooling operation.
Fig.4
(4) Thermostat Control Knob.
• If the room temperature is not as desired after a
reasonable period, turn the thermostat control knob
clockwise to make the room cooler or counter clockwise
to make the room warmer.
• When the thermostat control knob is set to 10, moisture
may freeze onto the evaporator fins and prevent
effective cooling. If this happens, turn the main control
knob to FAN and the thermostat control knob counter
clockwise. This will quickly defrost the evaporator fins so
that normal cooling can be resumed.
NOTE: Usually 4-5 is the recommended setting for heating
and 6-7 is the recommended setting for cooling.

(5) Air Swing Switch.
(Airflow direction adjustment side-to-side)
To obtain a fix airflow direction, set the Air Swing Switch to
“ON” for the vanes to swing from side to side until the
desired flow direction is reached, then switch it to “OFF”.
For continuous side-to-side air circulation, set the Air Swing
Switch to “ON”.

8.3.1. Installation Procedures
• Remove the screws from the rear cabinet.
• Slide the chassis out from the cabinet.
• Place cabinet into the installation hole.
8 Installation Instructions
8.1. Choosing the Installation Location
• When installing, use the nearest power outlet. Make sure the power outlet is easy to reach so you can quickly disconnect your
air conditioner in case of emergency.
• Ensure that the air conditioner is well supported, securely fastened, easily reachable and not obstructed.
• Avoid locations with: salty or sulphurous air, draughts, dampness and flammable gas.
• If you install the drainage system, be sure to channel the condensed water to a suitable location
• Covers, obstructions and unsteady support may cause excessive operating noise and vibration.
• The rear end of the air conditioner is splash proof. You need not shield or cover it.
8.2. Preparation for Installation
DIMENSION
• There should not be any obstacles surrounding the unit.
• Prepare an installation hole slightly bigger than the cabinet size.
• Left and right sides of the unit should be at least 15cm away from the wall
8.3. Installation Procedure

• Slide the chassis into the cabinet.
• Reinstall the cabinet screws. Secure the cabinet to chassis
by using screws (from rear cabinet).
Depending upon the location of the AC outlet, route the AC
cord to either the left or right side while installing the front grille.
• Place the front grille on the cabinet first. Secure the front
grille to the main chassis using screw provided.
• Attach the air filter to the front grille.
• Slide the front intake grille slightly to the right to reattach the
tabs and then push it down to close tight

8.3.2. Remove the Front Grille.
• Remove the front intake grille
Pull up the front intake grille about 90° and slide it slightly to
the left to unhook the tabs.
Caution: Do not raise the front intake grille anyhigher than
90°to the unit or damage to the tabs may occur.
• Remove the air filter.
Tilt up and pull out the air filter by holder.
• Remove the front grille.
1. At bottom right side of the front grille, press inward on
cabinet near the power cord, and pull the grille outward
to the right until right tab releases.
2. At bottom left side, push inward on cabinet and pull the
grille outward to the left to release the left tab. Do not
pull the bottom edge toward you more than 7.62cm to
prevent two top tabs from damage.
3. Slide the front grille upwards to free the two top tabs
from slots at the top of the cabinet.
8.3.3. Condensed water drainage
In order to drain off the condensed water, it is recommended
that you install a drain pan using the following procedure.
• Slide the chassis out from the cabinet.
• Install the drain pan.
Install the drain pan at the left corner of the cabinet using 2
screws.
• Connect a drain hose. Fit the drain hose to the drain pan.
NOTE: Drain hose or tubing can be purchased locally to satisfy
your particular needs.
• Slide the chassis back into the cabinet. Reinstall the cabinet
to the chassis by using screws.

8.4. Electric Work
• Always use at the rated voltage and with a specific air
conditioning circuit.
• Some installation locations may require the installation of a
short-circuit breaker.
• A 16 Ampere time delay fuse or circuit breaker is required.
• Nominal cross sectional area of power supply wire must be
3 core x 1.0 mm2or above.
• The power supply must be from an independent circuit.
• All electrical installations must be made in accordance with
local wiring and safety regulations wherever applicable.
• There must be a double pole switch with a minimum of 3
mm contact gap in the fixed installation circuit.
• Please engage an authorized dealer or specialist for the
installation work.
8.5. Noise Consideration
• Select an installation location that can support the weight of
the air conditioner and one that will not cause increased
operating noise and vibration.
• Ensure that airflow and noise from the rear side of the unit
(outdoor) when installed do not disturb neighboring
residents.
• Obstacles placed in front of the air outlet on the rear side of
the unit (outdoor), or covers placed over it will cause
excessive noise and deterioration in performance.
8.6. Transferring
• Repositioning or transfer of the air conditioner due to
renovation or moving requires an additional service charge.
Please consult your dealer before moving.
9 Care and Maintenance
Caution:
Always turn off the air conditioner and the main power supply before clean the unit.
Switch off the power supply if the unit is not going to be used for a long period of time.
• Clean the cabinet, front grille with a mild soap or detergent and lukewarm water.
• The front intake grille can be easily removed for cleaning purposes (refer to Remove the front intake grille procedures). Gently
wash it with water and a sponge.
• The filter can be easily cleaned using a vacuum cleaner. Vacuum the front of the filter and then wash the rear with water. If it
is badly soiled, wash with a mild household detergent.
• Do not clean with benzene, thinner, scouring powder or cloth soaked in caustic chemicals.
• If the unit is extremely dirty, heat transfer is less efficient and the unit may not cool effectively. Contact your nearest service
centre for an annual check. (Annual check is not covered under warranty)
• If the air filter becomes clogged with dust, the cooling or heating capacity will drop, and 6% of the electricity used to operate the
air conditioner will be wasted.
NOTE
Do not dry the front panel or the air filter in direct sunlight. (Exposure to direct sunlight may discolor or deform the panel.)
