1) Fan
Since the fan kit operates 24 hours every day continuously, any unusual
airflow obstruction must be cleared in time to avoid the damage to the
cooling system and other system components caused by reduced air
volume.
2) Drain pipe
Inspect water pan periodically for normal operation of the drain pipe. Ensure
that no foreign matter or leakage exits in the drain pipe.
3. Outdoor unit maintenance
1) Refrigeration system
The components of the refrigerant system should be inspected monthly for
finding abnormal operation phenomenon in time. Refrigerant pipes must be
properly fixed and not allowed to vibrate against wall, floor or the unit frame.
Inspect all refrigerant pipes every six months for signs of wear.
2) Air-cooled condenser
When the airflow through the outdoor unit is restricted, use compressed air
or fin cleaner (alkalescence) to clean the condenser off the dust and debris
that inhibit airflow. The compressed air should be blown at the reversed
airflow direction. In winter, do not let snow to accumulate around the side or
underneath the condenser. Check for bent or damaged fins and simply
repair them if necessary. Check all refrigerant pipes and capillaries for
vibration and support them if necessary. Carefully inspect all refrigerant
pipes for signs of oil leakage, thus determining the leakage position.
3) Compressor
The compressor fault is generally classified into two types:
Motor fault (such as winding burnout, insulation failure, short-circuit between
coils and so on).
Mechanical fault (such as compressing failure, relief valve fault, therm-o-disc
fault and so on).
If the operation pressure is not established, it indicates that the compressor
has failed. It can be confirmed if the suction pressure and discharge
pressure are balanced and the motor does not rotate reversely.
The controller has powerful alarm and protection functions to ensure safe
operation of the compressor. The maintenance personnel should record the
high pressure and low pressure and find out the cause of an alarm protection
during periodical maintenance and inspection.
