Be sure the power cord 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 also 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 to properly install it.

Ensure the receptacle is accessible after the

unit installation.

Do not run air conditioner without a side

protective cover.

This could result in mechanical damage within

the air conditioner.

The appliance shall be installed in accordance

with national wiring regulations.

Do not use an extension cord or an adapter

plug.

Power supply cord with 3-prong grounding plug

and current protection device

This unit has many features. The servicer must be familiar with these features in order to properly

Service the unit.

Operation of Current Device (optional)

The power supply cord contains a protection

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 RESET button, again you will notice a

Always make sure the RESET button is pushed in for proper 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 should be obtained from the manufacturer.

The power cord cannot be repaired. If the power cord is damaged, a new one should be obtained from

manufacturer or its service agent.

When 265V units are to be installed, the power supply must be done through permanent wiring.

Permanent wiring may be done through the accessory sub-base. An exposed cord connection on 265V

units is not permitted.

AIR CONDITIONER FEATURES

This unit has many features. The servicer must be familiar with these features in order to properly

service the unit.

Compressor Restart Delay

This feature extends the overall life of compressor by preventing the short-cycling of the air conditioner.

When the compressor restarts, the unit is designed to give a minimum of three minutes delay to

equalize the refrigerant pressures and optimize the cycling of unit.

Memory

The unit has a memory system .If power is lost, all the control settings (mode, fan speed, on/off and

Configuration) are saved. When power is restored, the unit starts in the same mode (and configuration)

it was in before the power was lost.

Automatic Evaporator Freeze Protection

To keep the evaporator from freezing, this feature activates automatically in which the compressor is

turned off and the indoor fan is turned on when the evaporator temperature gets too low.

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 the set heat is attained.

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 set point 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

NOTE: HEAT mode is for Cooling & Heating models only.

High Temperature Protection in Heating

Operation

The compressor and (or) electric heater will be switched off to prevent damage in high indoor blow air

temperature or error indoor temperature sensor.

CONTROL PANEL OPERATION

The control panel keypad will look like the following:

For some models with REMOTE SIGNAL RECEPTOR, the unit can be controlled by the control panel alone

or by the remote wall stat.

No REMOTE SIGNAL RECEPTOR.

Fig.1

POWER

- Press the POWER button to turn the unit on or off.

When the unit is on, the power indicator light will be green. When the unit is off, the light will go out.

MODE

- Push this button to cycle through the modes from COOL-HEAT-FAN-COOL. The indicator light beside

the "MODE" option will illuminate, displaying the mode selected.

- COOL: The range of set temperature is 17 C/62 F ~30 C/86 F. Cooling begins automatically when

the room temperature is above the set point, and stops when the room temperature is 2 C(4 F) below

the set point. But the compressor will run 5 minutes at least in COOL mode before stopping. The fan

runs in continuous mode.

- HEAT: The range of set temperature is 17 C/62 F ~29 C/84 F. For heat pump models, the unit can

alternate to run between in reverse cycle heat mode and electric heater mode according to the

difference between the setting temperature and the room temperature. The fan motor cycles on and off

with the compressor and electric heater.

NOTE: The reverse cycle and electric heater cannot be run at the same time.

- FAN: Fan operation only without heating and cooling.

UP/DOWN BUTTONS (+ / -)

- Push the UP (or DOWN) button to increase (or decrease) the set temperature of the unit in cooling or

heating mode. The temperature can be set by increments of 1 C (1 F).The setting temperature appears

in the display.

NOTE: Press and hold and buttons together for 3 seconds will alternate the temperature display

between C & F scale.

FAN (FAN SPEED)

- Every time you push this button, the fan speed cycles through the settings as follows HIGH-MED-LOW-

HIGH.

DISPLAYS:

- Shows the set temperature in C or F. While on Fan only mode, it shows the room temperature.

Control code (on some models):

LC-Pads on the control panel is not available. The unit can be set by using wire controller only.

LF-Pads on the control panel and wire controller are not available. The unit can be set by using

FRONT DESK CONTROL only.

Error codes:

AS-Room temperature sensor error;

ES-Evaporator temperature sensor error;

CS-Condenser temperature sensor error;

OS-Outside temperature sensor error;

HS-Exhaust temperature sensor error;

LE-Wire controller error;

NOTE: When the error occurs, unplug the unit and plug it again. If the error repeats, call for assistance.

Other codes:

LO-Room temperature is lower than 0 C/32 F;

HI-Room temperature is higher than 37 C/99 F.
