MAINTENANCE
OUTDOOR UNIT
1. Ensure power is off before cleaning.
2. It may be necessary to wash the outdoor coil more frequently if it is
exposed to substances which are corrosive or which block airflow
across the coil (e.g., pet urine, cottonwood seeds, fertilizers, fluids
that may contain high levels of corrosive chemicals such as salts).
3. Outdoor Coil (Sea Coast) - Moist air in ocean locations can carry
salt, which is corrosive to most metal. Units that are located near
the ocean require frequent inspections and maintenance. These
inspections will determine the need to wash the unit including the
outdoor coil. Consult your installing contractor for proper intervals/
procedures for your geographic area or service contract.
4. Outdoor unit fan motor is pre-lubricated and sealed. No further
lubrication is needed.
5. Visually inspect all connecting lines, joints and coils for evidence of
oil leaks.
6. Check all wiring for loose connections.
7. Check for correct voltage at unit (unit operating)

TROUBLESHOOTING
Whenever there is a problem with the system, an error code will be dis-
played on the front cover of the indoor unit. If more than one error has
occurred, the codes will alternate so that all codes are shown. Make
note of the code (E4, F6, H4, etc.), then reset the display by pressing
the ON/OFF button on the wireless remote. Press the ON/OFF button a
second time to reapply power to system. If code is still displayed, dis-
connect and restore power at the unit disconnect switch or circuit
breaker. If the problem was temporary, the code will not reappear. If the
error code reappears after power has been restored, contact your
HVAC contractor.
If one of the following situations occur, please unplug the unit and con-
tact your HVAC contractor immediately:
• There is very loud sound during operation
• The strong odor coming from the indoor unit during operation
• Water is leaking into the room
• Circuit breaker trips frequently
• Water or other liquid has been splashed into the indoor unit

calling your HVAC contractor.
