Service and Maintenance

Service & Maintenance

The design concept of the rooftop unit is such that all servicing can be done from the side and back of the

unit.
Upon removal of side and back panel, all the electrical “terminal box”, fan and motor assembly and

compressor are easily accessible.
Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil

surfaces once quarterly. However, if a unit is installed in area subjected to much oil, mist and dust, the

coil must be regularly cleaned by qualified Air Conditioner Service Technicians to ensure sufficient heat

exchange and proper operation. Otherwise, the systems life span might be shortened.

Note: Avoid direct contact of any coil treatment material on the plastic part. This may

cause plastic part to deform as a result of chemical reaction.

CAUTION

When the compressor is to be stopped for a long time, the crankcase heater should be

energized for at least 6 hours before start of operation.

Do not charge

OXYGEN, ACETYLENE OR OTHER FLAMMABLE

and poisonous gases into

the refrigeration cycle when performing a leakage test or an airtight test. These types of gases

are extremely dangerous, because explosion can occur.

It is recommended that nitrogen or refrigerant be charged for these types of tests.

CAUTION FOR USE

Bear the following points in mind to safeguard against malfunction and breakdown.

Do not stick rods or other objects through the air outlet during operation since this may result to damage or

injury

The air conditioner must not re-start within 3 minutes after shutdown. (These models are equipped with a

crankcase heater with the compressor).

SHUTDOWN

OPERATION

3 minutes

Make sure the air conditioner is properly grounded by checking the ground terminal.
