MAINTENANCE WORK
n
For Indoor Unit and Outdoor Unit
1. Fan and Fan Motor
Lubrication: All fan motors are pre-lubricated and
sealed at the factory. Therefore, no lubricating
maintenance is required.
Sound and Vibration: Inspect for abnormal sound and
vibration
Rotation: Inspect for clockwise rotation and rotating
speed.
Insulation: Inspect for electrical insulation resistance.
2. Heat Exchanger
Clog: Inspect and remove any accumulated dirt and
dust from the heat exchanger at regular intervals. As
for outdoor unit, other obstacles such as growing
grass and pieces of paper, which might restrict air
flow, should also be removed.
3. Piping Connection
Leakage: Inspect for refrigerant leakage at piping
connection.
4. Cabinet
Stain and Lubrication: Inspect and remove any stain
and lubrication.
Fixing Screw: Inspect and fix loosened or lost screws.
Insulation: Inspect and repair peeled thermal
insulation material on cabinet.
5. Electrical Equipment
Activation: Inspect for abnormal activation of the
magnetic contactor, auxiliary relay, PCB and etc.
Line Condition: Pay attention to working voltage,
amperage and phase balance. Inspect for faulty
contact caused by loosened terminal connections,
oxidized contacts, foreign matter, and other items.
Inspect for electrical insulation resistance.
6. Control and Protective Devices
Setting: Do not readjust the setting in the field unless
the setting is maintained at a point other than the
point listed in "9.6. SAFETY AND CONTROL DEVICE
SETTING" of "TC"
n
For Indoor Unit
1. Air Filter
Cleaning: Inspect and remove any accumulated dirt
and dust according to "18.2 Filter Cleaning" of "TC".
2. Drain Pan, Drain - up Mechanism and Drain Pipe
Drain Line: Inspect and clean the condensate drain
line at least twice a year.
Drain-up Mechanism: Inspect for activation of drain-up
mechanism.
3. Float Switch
Activation: Inspect for activation of float switch.
n
For Outdoor Unit
1. Compressor
Sound and Vibration: Inspect for abnormal sound and
vibration.
Activation: Inspect for that the voltage drop of power
supply line is within 15% at start and within 2% during
operation.
2. Reverse Valve
Activation: Inspect for any abnormal activating sound.
3. Strainer
Clog: Inspect for that no temperature difference
between both ends.
4. Earth Wire
Earth Line: Inspect for continuity to the earth.
5. Oil Heater
Activation: The oil heater should be activated at least
12 hours before start- up, by switching ON the main
power source.
