1. PREFACE

This SERVICE MANUAL provides various service information, including the mechanical and electrical parts etc. This room air conditioner was manufactured and assembled under a strict quality control system. The refrigerant is charged at the factory. Be sure to read the safety precautions prior to servicing the unit.

1.1 SAFETY PRECAUTIONS

1.When servicing, turn the unit Off and unplug the power cord.

2.Observe the original lead dress.

If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.

3.After servicing, make an insulation resistance test to prevent the customer from being exposed to shock hazards.

1.2 INSULATION RESISTANCE TEST

1.Unplug the power cord and connect a jumper between 2 pins (black and white).

2.The grounding conductor (green or green and yellow) is to be

.open.

3.Measure the resistance value with an ohm meter between the

.jumpered lead and each exposed metallic part on the equipment at each working status.

4.The value should be over 1 MΩ.

POWER BUTTON

To turn the air conditioner ON. To turn the air conditioner OFF, push the button again. This button takes priority over any other buttons.

TEMPERATURE SETTING BUTTON

This button can automatically control temperature of the room. The temperature can be set within a range of 60'F to 86'F by 1'F.

OPERATION MODE SELECTION BUTTON

Every time you push this button, it will shift operation between COOL, ENERGY SAVER, FAN and DRY modes.

- Money Saver: If Money Save mode is selected, the fan stops when the compressor stops cooling.

Approximately every 3 minutes the fan will turn on and check the room air to determine if cooling is needed.

FAN SPEED SELECTOR

Every time you push this button, it will shift fan speeds, as follows. (Hi Low Med Hi Low ...)

ON/OFF TIMER BUTTON

ON - When the air conditioner is off,it can be set to automatically come on in 1 to12 hours from its previous setting. Each touch will increase the timer by 1 hour.

OFF - When the air conditioner is on, it can be set to automatically turn off in 1 to 12 hours. Each touch will increase the timer by 1 hour. After the timer has been on for 30min, the temperature will automatically rise 2F, and after another another 30min, it will rise 2F again. The temperature will stay the same until the timer goes off.

To cancel the timer, press the timer pad until the display time disappears.
