A proper interior temperature in summer is 5 - 6° C (10 -

Operate the air conditioner from twenty - thirty minutes a
week to circulate the refrigerant in the system.

The blower switch must be on "LO" speed.
NOTE:
The filter must be cleaned out every 500 hours and
replaced with a new one every 1,000 hours.
NOTE:
In the event that the unit is being operated in a dusty
environment, the cleaning and replacement must be
performed more frequently.
If operating the air conditioner or heater for a long time,
operate the ventilation switch, and when smoking, vent the
air to the outside to prevent irritation to eyes.
