COOLING
Choose the cooling comfort setting desired, low or
high cool.
FAN
Set the master control to low or high position, and
the fan will operate to circulate room air without
cooling.
When switching to the fan only setting, allow a few
minutes before switching unit back to the cooling
operation.
OFF
Turn the master control knob to OFF, and all func-
tions will stop.
EXHAUST CONTROL
Your unit is equipped with an exhaust air system.
This function expels stale, smoky odor laden air
from the room to the outside. To operate slide the
exhaust lever to the open position, and turn the
master control to a low or high fan setting.
NOTE:The lever should be in the “CLOSED” posi-
tion in order to maintain the best cooling effect
when air ventilation is not desired.
THERMOSTAT
Maintains room temperature automatically. To
determine your desired temperature setting, turn
the thermostat towards COOLER for lower temper-
ature control, or towards WARMER if a higher tem-
per-ature setting is desired. Cooling operation auto-
matically starts when the room temperature rises
above your desired thermostat setting, and stops
when the room temperature reaches your desired
setting.
NOTE:The fan will operate continuously to main
tain optimum temperature control.
AIR DIRECTION CONTROL
140 Casing
The up/down direction air louvers are controlled by
fingertip pressure on the louvers.
They regulate air discharge upward, downward, or
straight ahead.
Two separate banks, of side to side air direction
louvers have separate tabs to let you direct dis-
charged air to the right, to the left, of straight ahead.
150 Casing
When the AUTO AIR SWEEP switch is set to on (l),
the vertical air deflector moves slowly left and right
and distributes air around room.
Vertical blades may be stopped at any position
when the switch is off (O).
The horizontal air deflectors are adjusted manually.

Select the thermostat setting that suits your comfort
needs and leave thermostat at that chosen setting.
Keep unit's filter clean. Normally filter should be
cleaned every 30 days. The filter is very efficient in
removing airborne particles.
More frequent cleaning may be necessary depend-
ing on the air quality.
How to remove filter:
Remove the air filter by pulling it rightward.
How to clean the air filter:
Wash away dust from the air filter with clean water
or vacuum the filter with an electric house hold vac-
uum cleaner.
Use drapes, curtains, shades, to keep direct sun-
light from heating the room.
Do not obstruct the front of the unit.
REMEMBER:Maximum cooling efficiency is
achieved when exhaust system is off. Check to
make sure exhaust control is not on while unit is
cooling.
Start your air conditioner before outside temper-
atures, cooking heat or gatherings of people make
room hot and uncomfortable. This avoids initial
period of discomfort while unit is cooling off room.
Even without above tips, your room air conditioner
is designed to be highly efficient in energy savings.

WARNING
INSTALLATION INSTRUCTIONS
Step 1 –Determine Window Location.
Determine a suitable location.
The window where the Air Conditioner is
to be installed should have enough
strength to bear the weight of the
Air Conditioner.
Step 2 –Measure unit's dimensions.
Step 3 –Install the Mounting Angle at the Proper
Location
Install the Air Conditioner using the Mounting Angle
or other Mounting Hardware where you want. The
Mounting Angle or other Hardware to be installed
as shown in Fig. 3
For proper drainage, Rear side of the Unit should be
inclined about 10 mm lower.

WINDOW INSTALLATION
Mounting Angle Installation.
Fig. 3
Two people must work together to avoid personal
injury.
Step 5 – Finish opening
Close up the gap between unit and
window using the sponge or tape for
insulation as shown in Fig. 3.
Through-the-wall installation can be made in
wood framing or masonry walls with or without
field-supplied wall sleeve. The casing or sleeve
must be installed level so that built-in pitch to out-
side aids in draining condensate. The installation
should be weather-proof outside and finished
inside.
Installations in wood framed or masonry walls can
be made using the casing as a sleeve. Fasten the
casing directly to masonry or studding using field-
supplied masonry or wood screws.
Minimum Louver Clearance

CAUTION

OWNER’S GUIDE - 6
If wall thickness overlaps the side louvers in unit
casing, make wall opening wider, as shown in Fig.
4. Also, make provisions for condensate drainage
from basepan. If wall projects beyond back of unit,
use baffles on rear corners of casing. Fig. 4 shows
location of baffles (*a).
The Operating and Maintenance Instructions are in
the Owner’s Handbook supplied with the air condi-
tioner.
The installer must be sure that the user receives a
