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 your 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 rem ove any prong from the power cord.
WARNING El ectrical 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 , und er a ny
cir cum s tan ces , cut ,
rem ove, or bypass
the grounding p rong.

Operation of Cu rrent D evice
The power supply cord contains a current device that senses damage to the power cord. To test your power
supply cord do the following:
1. Plug in the Air Conditioner.
2. The power supply cord will have TWO buttons on the plug head.
Press the TEST button, you will notice a click as the RESET
button pops out.
3. Press the RESE T button, again you will notice a click as the button
engages.
4. The power supply cord is now supplying electricity to the unit.
(On some products this it also indicated by a light on the plug head.)
Do not use this device to turn the unit on or off.
Always make sure the RESET button is pushed in for correct operation.
The power supply must be replaced if it fails reset when either the TEST button is pushed, or it cannot be
reset. A new one can be obtained from the product manufacturer.
If power supply cord is damaged, it cannot be repaired. It MUST be replaced by one

This unit has many featrues.The servicer must be
familiar with these features in order to properly
service the unit.
AIR CONDITIONER FEATURES
Compressor Restart Delay
This feature extends the overall life of compre-
ssor by preventing the short-cycling of the air
conditioner.When the compressor restarts,the
unit is designed to give a minimum of three
minutes to have a time of equalizing the refrig-
erant pressures for optimizing cycling.
Memory
The unit has memory .If power is lost,all of the
control settings(mode,fan speed,on/off and
configuration) are remembered.So when power
is restored,the unit will start back up in the mode
(and configuration) it was in,when power was
lost.
Automatic Evaporator Freeze Protection
Automatically to keep the evaporator from
freezing,the compressor is tuuned off and the
indoor fan is turned on when the evaporator
temperature is too lower.If the evaporator
temperature is not too lower this function is off.
Automatic Defrost Protection (for heat pump
models only)
When the outdoor tube temperature gets too
cold the unit will automatically switch to electric
heating and the compressor will be off. The unit
will then heat with electric heat until the outside
temperature rises enough,so the compressor
can be used again.
Automatic Quick Warm-up (for heat pump
models only)
If the room temperature falls to 4.5 C/8 F
below the set point temperature,the reverse
cycle heat is shut off and the electric strip heat
is turned on for one cycle,until heating is
satisfied.
O O
LED Indicators and Buttons
The touch pad has buttons for MODE,FAN,
POWER,SETPOINT UP and SETPOINT DOWN.
It also has LEDs that correspond to the mode,
fan speed,power and setpoint operation,to
indicate the unit s status.LEDs for HIGH,MED
and LOW indicate the fan speed that is selected.
LEDs for FAN,COOL and HEAT indicate what
operating mode is active.LED for POWER is the
unit ON/OFF status LED.If the unit is in ON mode,
the LED will be green.If the unit is OFF,the LED
will be off.
,
Unit Configuration
NO TE: HEAT mode is for Cooling & Heating models only.

F or C
The unit can display in either F or C.

High Temperature Protection In Heating
Operation
The compressor and(or) electric heater will be
switched off to prevent damage in high indoor
blow air temper ature or error indoor temperature

INSTALLATION
HOW TO INSTALL THE UNIT
- For existing sleeve,you shou ld measure the wall
sleeve dimensions.
- Install the new air cond itioner according to these
installation instructions to achieve the best performan ce.
All wall sleeves used to mount the ne w air conditioner
mu st be in goo d structural con dition and have a rear
grille that securely attaches to the sleeve or the flange
of the sleeve to secure the new air condition er.

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 edg es that can cause serious cuts.
When lifting the air cond itioner,it is HEAVY.Use 2
peo ple to lift.
