The unit will make different sounds based on its current operating
mode.
The unit may accumulate dust during extended periods of non-use,
which will be emitted when the unit is turned on. This can be mitiga-
ted by covering the unit during long periods of inactivity.
The unit may absorb odors from the environment (such as furniture,
cooking, cigarettes, etc.) which will be emitted during operations.
The unit's filters have become moldy and should be cleaned.
During operation, the fan speed is controlled to optimize product
operation.
lnterference from cell phone towers and remote boosters may cause
the unit to malfunction.
In this case, try the following:
• Disconnect the power, then reconnect.
• Press ON/OFF button on remote control to restart operation.
Possible Causes
Temperature setting may be higher
than ambient room temperature
The heat exchanger on the indoor
or outdoor unit is dirty
The air filter is dirty
The air inlet or outlet of either unit
is blocked
Doors and windows are open
Excessive heat is generated by
sunlight
Too many sources of heat in the
room (people, computers, electro-
nics, etc.)
Low refrigerant due to leak or
long-term use
SILENCE function is activated (opti-
onal function)
Solution
Lower the temperature setting
Clean the affected heat exchanger
Remove the filter and clean it ac-
cording to instructions
Turn the unit off, remove the ob-
struction and turn it back on
Make sure that all doors and win-
dows are closed while operating
the unit
Close windows and curtains during
periods of high heat or bright
sunshine
Reduce amount of heat sources
Check for leaks, re-seal if necessary
and top off refrigerant
SILENCE function can lower product
performance by reducing operating
frequency. Turn off SILENCE func-
tion.
