11-6-1 Cleaning
There is no need for routine condenser cleaning in normal Home operating environments. If the environment is
particularly greasy or dusty, or there is significant pet traffic in the home, the condenser should be cleaned
every 2 to 3 months to ensure maximum efficiency.
If you need to clean the condenser:
Remove the mechanical cover.
Use a vacuum cleaner with a soft brush to clean the grille, the open areas behind the grille and the front
surface area of the condenser.
Replace the mechanical cover.

REMARKS
• Refrigerant level is low due
to a leak.
• Normal cooling is possible by
restoring the normal amount
of refrigerant and repairing
the leak.
• No discharging of
Refrigerant.
• Normal cooling is possible by
restoring the normal amount
of refrigerant and repairing
the leak.
• Normal discharging of the
refrigerant.
• The capillary tube is faulty.
• Normal discharging of the
Refrigerant.
• Cooling operation restarts
when heating the inlet of the
capillary tube.
• Low pressure at high side of
compressor due to low
refrigerant level.
• No pressure in the high
pressure part of the
compressor.
