owing noise of refrigerant in the refrigerating cycle.

(2) Slight rubbing noise from the fan casing which is cooled and then

gradually warmed as operation stops.

to reduce the odor.

inspections. Inform your agent of the model of your unit, production number, date of installation. Please also
inform him regarding the fault.
