Servicing And Maintenance
The design concept of the Condensing Unit is such that all servicing can be done from the front and side of the unit.
Upon removal of front and side 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.
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).
Make sure the air conditioner is properly grounded by checking the ground terminal.
MAINTENANCE
For superb performance and lasting durability, please do not forget to conduct proper and regular maintenance.
Cleaning The Outdoor Unit Heat Exchanger
If you use your air conditioner for prolonged period of time, the outdoor unit heat exchanger will become dirty
impairing its function and reducing the performance of the air conditioned. Consult your local dealer about the cleaning of
the heat exchanger.
