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
room temperature rises
above, cooling resumes. This
results in efficient use of power and economical cooling.
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.
The vertical louvers may be
stopped at any position
(during oscillation) when the
AUTO LOUVER / AUTO
SWING switch is turned OFF .
Manual Vertical Air Flow
Adjustment : To adjust vertical
air flow direction, adjust any
one of the horizontal louver
blades. When turning the
blades upwards
downwards, always keep the
top or bottom blades
horizontal. This can effectively
prevent condensation of water
on the front panel of the unit.
OPERATION DETAILS
HEATING MODELS)
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)
or
(COOLING & ELECTRIC
model that you have purchased. While some differences
may be there in the appearance, the functions of the various
components are the same.
1
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.
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
reduced. When it is set at
HIGH COOL fast cooling is
achieved. At LOW COOL the
cooling is relatively low.
At HIGH HEAT, rapid heating
takes place. At low heat, the
rate of heating is relatively
lower. At OFF, the
conditioner remains switched
off. On FAN, only the fan runs
with no cooling or heating.
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.
During cooling operation, if the thermostat knob has
been turned in the direction from '12' to '1', be sure to
wait at least three minutes before turning the knob back
toward '12'. Immediate turning of the knob may result in
a blown fuse
