ROOM AIR CONDITIONERS
THERMOSTAT
The thermostat automatically
starts and stops the running of
the compressor in the air
conditioner in order to control
and maintain a comfortable
room temperature. When the
room temperature reaches the
desired setting, cooling will
automatically stop. When the
temperature
rises

results in efficient use of power and economical cooling.
model that you have purchased. While some differences
may be there in the appearance, the functions of the various
components are the same.

The operation is as follows : As the knob is turned towards
the right, the thermostat is set for a ‘COOLER’ temperature.
If the temperature becomes too cold, turn the knob towards
the left to set thermostat for warmer temperatures.
Note : TEST RUN is used to test the compressor and
make sure unit is working properly. When the knob is
rotated to this position, the unit is kept in cooling mode
and automatic temperature control is cut off. Do not use
this position for regular operation.
During the cooling operation of the unit, when the cooler
temperatures are required, wait at least three minutes,
otherwise the fuse may blow due to an overload of the
unit.
AUTO LOUVRE / AUTO SWING
Automatic horizontal air flow
adjustment : When the AUTO
LOUVER / AUTO SWING
switch is turned to ON
position, the vertical louvers
automatically oscillate left and
right sweeping the cold air
across the room to obtain
comfortable cooling.
CAUTION
When the switch is set to HIGH FAN or LOW FAN, the
air conditioner only blows air, without cooling or heating.
Knob should be turned slowly from LOW COOL or LOW
HEAT to HIGH COOL or HIGH HEAT.
When room temperature drops below 21°C and the unit
is in cooling operation, frost may form on the evaporator.
If this occurs, operate the air conditioner on the FAN
setting to defrost.
&
ELECTRIC
The operating panel will like on of the figures given below.
The design of the operation panel is based on the particular
IOM # 036 - 3007 TP (0206)
The function selection knob
controls fan speed and the
cooling speed. When it is set
to HIGH FAN a large volume of
air is discharged. When it is
set to LOW FAN, the volume if
air being discharged is
reduced. When it is set at
HIGH COOL fast cooling is
achieved. At LOW COOL the
cooling is relatively low.
!
Manual Vertical Air Flow
Adjustment : To adjust vertical
air flow direction, adjust any
one of the horizontal louver
blades. When turning the
blades
upwards
or
downwards, always keep the
top
or
bottom
blades
horizontal. This can effectively
prevent condensation of water
on the front panel of the unit.
(COOLING
Power indicator (selected models only) : This indicator
light remains on when the unit is on and goes off when the
SELECTOR is on OFF position.
At HIGH HEAT, rapid heating
takes place. At low heat, the
rate of heating is relatively
lower. At OFF, the air
conditioner remains switched
off. On FAN, only the fan runs
with no cooling or heating.
The vertical louvers may be
stopped at any position
(during oscillation) when the
AUTO LOUVER / AUTO
SWING switch is turned OFF .

OPERATIONAL
CAUTION
TO AVOID THE POSSIBILITY OF INJURY, BE SURE
TO DISCONNECT POWER SUPPLY TO THE UNIT
BEFORE SERVICING AND / OR CLEANING.
Do
Not
use
gasoline,
benzene, thinner or any other
chemicals, or insecticide to
clean the air conditioner, as
these substances may cause
flaking off of the paint, and
cracking or deformation of
plastic parts.
Never attempt to clean the
unit by pouring water directly
over any of the surface areas,
as this will cause deterioration
of electrical components and
wiring insulation and it may
cause a short circuit or
electrocution.
CLEANING THE AIR FILTER
If the air filter becomes clogged with dust, air flow is
obstructed which reduces the cooling efficiency. The air filter
should be cleaned every two weeks.
IOM # 036 - 3007 TP (0206)
Remove Air Filter (See
Installation Instructions,
Step 1, on Page 7).

TROUBLE
SHOOTING
Problem : Unit is working, but cooling is not sufficient.
Possible Cause : It is quite
possible that the supply or
exhaust grill is blocked. This
prevents the unit from efficient
cooling.
Remove
any
obstructions.
Possible Cause : The outdoor
temperature
may
be
abnormally high due to the
unit being exposed to an
external source of heat.
