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 | 1.2 INSULATION RESISTANCE TEST |
1.When servicing the unit, turn off the air conditioner 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 the unit, make an insulation resistance test to protect the customer from being exposed to shock hazards.
1.Unplug the power cord and connect a jumper between 2 pins (black and white).
2.The grounding conductor (green or green & 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.
4.The value should be over 1M .
