Electrical specifications
1. All wiring must comply with local and national
electrical codes and must be installed by a
!
Electric Shock Hazard
licenced electrician. If you have any questions
regarding the following instructions, contact a
licenced electrician.
If the air conditioner has a serial plate rating
of 115 volts and up to and including 7.5 amps,
the unit maybe on a fuse or circuit breaker
with other devices. However, the maximum
amps on all devices for that fuse or circuit
breaker can not exceed the amps of the fuse
for the circuit breaker.
2. Check available power supply and resolve any
wiring problems BEFORE installing and operating
this unit.
If the air conditioner has a serial plate rating
of 115 volts and greater than 7.5 amps it
must have its own fuse or circuit breaker,
and no other device or unit should be
operated on the fuse or circuit breaker.
3. For your safety and protection, this unit is
grounded through the power cord when
plugged into a matching wall outlet. If you are
not sure whether your wall outlet is properly
grounded, please consult a licenced
electrician.
If the air conditioner has a serial plate rating
of 230 volts, it must have its own fuse or
circuit breaker, and no other device or unit
should be operated on the fuse or circuit
breaker.
4. The wall outlet (3-pin) must match the plug
(3-pin) on the power cord supplied with the unit.
DO NOT use plug adapters or extension cords.
See (Table 1) for receptacle and fuse information.
5. The rating plate on the unit contains electrical
and other technical data. The rating plate is
located on the right side of the unit. Make sure
to use the correct power supply according to the
rating plate of your air conditioner.
To avoid the possibility of personal injury,
disconnect power to the unit before installing
or servicing.

Tips before installation
Your RoomAir Conditioner unit is designed to
be highly efficient and save energy. Follow these
!
!
CAUTION
To avoid installation/operating difficulties,
read the instructions thoroughly.
recommendations for greater efficiency.
1. Select thermostat setting that suits your
comfort needs and leave the thermostat at
that chosen setting.
NOTE:
Save the shipping carton and packing
materials for future storage or transport of the unit.
Please check the contents of the hardware kit against
the corresponding model check list, prior to
installation of the unit.
2. The air filter is very efficient in removing airborne
particles. Keep the air filter clean. Typically, the filter
should be cleaned once a month. More
frequent cleaning may be necessary depending
on outdoor and indoor air quality.
See lists below.(Fig.A)
3. Use drapes, curtains, or shades to keep
direct sunlight from heating your room, but
DO NOT obstruct the air conditioner.Allow air to
circulate around the unit without obstructions.

3/4"Screws (10)
Shutter Clamp(2)
1/4"Screws (23)
Washer(10)
4. Start your air conditioner before outdoor
air becomes hot/cold and uncomfortable. This
avoids an initial period of discomfort while
the unit is cooling or heating off the room.

5. When outdoor temperature is cool
enough, use HIGH or LOW FAN
only. This circulates indoor air, providing
some cooling comfort, and utilizes less
electricity than when operating on a
cooling setting.

Installation instructions
E. Be certain the proper electrical outlet is within reach
of the installation. Use only a single outlet circuit rated
at proper current (see table 1 on page 4). All wiring
should be in accordance with local and national
electrical codes.
!
!
CAUTION
Because the compressor is located on the
controls side of the unit (right side), this side
will be heavier and more awkward to manipulate.
Inadequate support on control side of the unit
can result in personal injury and damage to your
unit and property. Therefore, it is recommended
to have someone assist you during the installation
of this unit.
F. Your unit was designed to evaporate condensation
under normal conditions. However, under extreme
humidity conditions, excess condensation may cause
the basepan to overflow to the outside.
The unit should be installed where condensation
run-off cannot drip on pedestrians or neighboring
properties.
1. Select the Best Location
A. Your room air conditioner was designed to
fit easily into a single or double hung window. However,
since window designs vary, it may be necessary to
make some modifications for safe and proper
installation.

C. For maximum efficiency, install the air conditioner
on side of the house or building which favors more
shade than sunlight. If the unit is in direct sunlight,
it is advisable to provide an awning over the unit.

D. Provide sufficient clearance around the cabinet
to allow for ample air circulation through the unit.

Care and Maintenance
When servicing the air conditioner, be sure to
turn the mode switch to the "OFF" position and
disconnect the power cord from the electrical outlet.
!
!
CAUTION
DO NOT forget to install the air filter. If the air
conditioner is left to operate without the air filter,
dust is not removed from the room and may
cause your air conditioner to fail.
1. DO NOT use gasoline, benzine, thinner or
other chemicals on the air conditioner as these
substances may cause damage to the paint finish
and deformation of plastic parts.
When the air filter inlet grill and cabinet are dirty,
wipe with lukewarm water (below 40 C/104 F).
Use of mild detergent is recommended.
2. Never attempt to pour water directly in
front of the unit as this will cause deterioration of
the electrical insulation.
Cleaning of Air Filter
Cleaning the Air Filter
Removal of Air Filter
1. Remove dust clogged in the filter by
tapping it or vacuum clean it.
If the air filter becomes clogged with dust, air-flow
is obstructed and reduces efficiency. The air filter
should be cleaned once a month. More frequent
cleaning may be necessary depending on outdoor
and indoor air quality.
2. Wash the filter well with lukewarm water below
40 C (104 F) while rubbing lightly: To get better
results, wash it with soapy water or a neutral
cleaning agent.
3. Rinse the filter well using clean water then
dry completely.
Air Filter Removal:
The air filter on the above model is located
behind the air intake front grill.
End-of-Season Care
To remove the air filter, open the air inlet grille and
take the air filter .
1. Operate the fan alone for half a day to dry out
the inside of the unit.
To reinstall the air filter, reverse the above procedure.
2. Turn off power and remove plug from wall socket.
3. Clean filter.
4. Store in a dry location.

Replace drain plug.
Clean unit thoroughly.
Water dripping outside
Water dripping inside
Condensation run-off is normal Add flexible tubing to redirect water flow,
during hot and humid weather see (Fig.14 Page 10.)
U.nit is not properly angled to
allow water to drain outside.
Unit must be installed on an angle for proper
condensation run-off. Check the unit and
make adjustments.
