IMPORTANT SAFETY INSTRUCTIONS

Be sure the electrical service is adequate for the model you have
chosen. This information can be found on the serial plate, which
is located on the side of the cabinet and behind the grille.
Be sure the air conditioner is properly grounded. To minimize
shock and fire hazards, proper grounding is important. The power
cord is equipped with a three-prong grounding plug for protection
against shock hazards.
Your air conditioner must be used in a properly grounded wall
receptacle. If the wall receptacle you intend to use is not adequately
grounded or protected by a time delay fuse or circuit breaker,
have a qualified electrician install the proper receptacle.
Ensure the receptacle is accessible after the unit installation.
Do not run air conditioner without side protective cover in place.
This could result in mechanical damage within the air conditioner.

Do not use an extension cord or an adapter plug.

WARNING

For you r safety

Do not store or use gasoline or other flammable vapors and liquids in
the vicinity of this or any other appliance.
Avoid fire hazard or electric shock. Do not use an extension cord or an
adaptor plug. Do not remove any prong from the power cord.

WARNING

Ele ctrica l Infor mation

NOTE The power supply cord with

this air conditioner contains a current
detection device designed to reduce
the risk of fire.
Please refer to the section Operation
of Current Device for details.
In the event that the power supply
cord is damaged, it cannot be
repaired-it must be replaced with a
cord from the Product Manufacturer.

,

,

Do not, under any
circumstances, cut,
remove, or bypass
the grounding prong.

INSTALLATION

HOW TO INSTALL THE UNIT

- For existing sleeve,you should measure the wall
sleeve dimensions.

- Install the new air conditioner according to these
installation instructions to achieve the best performance.
All wall sleeves used to mount the new air conditioner
must be in good structural condition and have a rear
grille that securely attaches to the sleeve or the flange
of the sleeve to secure the new air conditioner.

- To avoid vibration and noise,make sure the unit is
installed securely and firmly.

- When installing the sleeve,make certain there is
nothing within 20 of the back that would interfere
with heat radiation and exhaust air flow. (See Fig.2)

!

CAUTION

There are sharp edges that can cause serious cuts.
When lifting the air conditioner,it is HEAVY.Use 2
people to lift.

NOTE:When vent control lever set at CLOSE,only
the air inside the room is circulated and filtered.
When set at OPEN,some outdoor air will be drawn
into room.This will reduce heating or cooling
efficiency.

!

CAUTION

Do not put obstacles around air-inlet or
inside of air-outlet of the unit, such as window
curtain etc.

Always insert the filter securely, clean filter once
every two weeks as required.

CARE AND CLEANING

FRONT PANEL AND CASE

- Turn unit off and disconnect power supply.To clean,
use water and a mild detergent.DO NOT use bleach
and abrasivers.Some commercial cleaners may
damage the plastic parts.

- Removing Air Filter

Fig.9

OUTDOOR COIL

- Coil on outdoor side of unit should be checked
regularly.Unit will need to be removed to inspect
dirt build-up that will occur on the inside of the coil.
If clogged with dirt and soot ,coil should be
professionally cleaned.Clean inside and outside of
outdoor coils regularly.
NOTE: Never use a high-pressure spray on coil.

!

CAUTION

Failure to follow this caution may result in
equipment damge or improper operation.
Airflow restriction may cause damage to the unit.

UNIT DAMAGE HAZARD

AIR FILTERS
IMPORTANT:TURN UNIT OFF BEFORE
CLEANING.

- The most important thing you can do to maintain
unit efficiency is to clean the filters once every
two weeks as required.
Clogged filters reduce cooling,heating and airflow.

!

CAUTION

Failure to follow this caution may result in
equipment damge or improper operation.
Do not operate unit without filters in place.If a filter
becomes torn or damaged,it should be replaced
immediately.
Operating without filters in place or with damaged
filter will allow dirt and dust to reach indoor coil and
reduce cooling,heating,airflow and efficiency of unit.
Airflow restriction may cause damage to unit.

UNIT DAMAGE HAZARD

- Keeping filters clean will:
Decrease cost of operation.
Save energy.
Prevent clogged indoor coil.
Reduce risk of premature component failure.

- To Clean Air Filters:
Vacuum off heavy soil.
Run water through filter.
Dry thoroughly before replacing.

TROUBLESHOOTING

SOLUTONSPOSSIBLE CAUSES

UNIT DOES NOT START

Unit may have become unplugged
Fuse may have blown
Circuit breaker may have been tripped
Unit may be off
Unit may be in a protection mode.

Check that plug is plugged securely in wall receptacle.
Note:Plug has a test/reset button on it.Make sure that the plug has
not tripped.
Replace the fuse.See Note 1.
Reset circuit breaker.See Note 1.
Turn unit on (bottom right button on keypad).

UNIT NOT COOLING/HEATING ROOM

Unit air discharge section is blocked
Temperature setting is not high or low
enough
Note:Setpoint limits may not allow the
unit to heat or cool the room to the
temperature desired.Check section on
dipswitch settings.
Unit air filters are dirty.
Room is excessively hot or cold when
unit is started.
Vent door left open.
Unit may be in a protection mode.
Compressor is in time delay.

Make sure that curtains,blinds or furniture are not restricting or
blocking unit airflow.
Reset to a lower or higher temperature setting.
Remove and clean filters.
Allow sufficient amount of time for unit to heat or cool the room.Start
heating or cooling early before outdoor temperature,cooking heat or
gatherings of people make room uncomfortable.
Close vent door.
Check dipswitch settings for desired comfort.
Wait approximately 3 minutes for compressor to start.

DISPLAY HAS STRANGE NUMBERS/
CHARACTERS ON IT

The unit may be in a protection mode.

O O

The unit may be set for C (instead of F).

UNIT MAKING NOISES

Clicking,gurging and whooshing noises are normal during operation
of unit.

WATER DRIPPING OUTSIDE

If a drain kit has not been installed,condensation runoff during very
hot and humid weather is normal.See Note 2.If a drain kit has been
installed and is connected to a drain system,check gaskets and
fittings around drain for leaks and plugs.

WATER DRIPPING INSIDE

Wall sleeve is not installed level

Wall sleeve must be installed level for proper drainage of
condensation .Check that installation is level and make any
necessary adjustments.

ICE OR FROST FORMS ON INDOOR
COIL

Low outdoor temperature
Dirty filters

When outdoor temperature is approximately 55OF or below,frost
may form on the indoor coil when unit is in Cooling mode.Switch unit
to FAN operation until ice or frost melts.
Remove and clean filters.

COMPRESSOR PROTECTION

Power may have cycled,so compressor
is in a restart protection.

Random Compressor restart-Whenever the unit is plugged in,or
power has been restarted,a random compressor restart will occur.
After a power outage,the compressor will restart after approximately
3 minutes.
Compressor Protection-To prevent short cycling of the compressor,
there is a random startup delay of 3 minutes and a minimum
compressor run time of 3 minutes.

NOTES:

1.If circuit breaker is tripped or fuse is blown more than once,contact a qualified electrician.

2.If unit is installed where condensation drainage could drip in an undesirable location,an accessory drain kit
should be installed and connected to drain system.
