[Features of Heating Operations]
Basic principles and performances
O
The machines absorb heat from the outdoor air and transfer it indoors so as to heat the room air. The heating capabilities
through this principle of heat pump go up/down with the increase/decrease of the temperatures of the outdoor air.
O
It only needs a fairly short time for such hot air circulation system to raise the room temperature.
0
When the outdoor air temperature is very low, the system can be used together with other heating devices. But good
ventilation should be maintained to ensure safety and prevent accidents.
Defrosting
When the outdoor air temperature is very low and humidity is very high, frosting will occur to the heat exchanger of the outdoor
unit, which has negative impacts upon the efficiency of the heating performance. In such case, the automatic defrosting function
will come into play. The heating operation will be stopped for 5-10 minutes to do the defrosting.
O The fans of both the outdoor and indoor units are stopped. During the defrosting operation, the run light will flash
slowly.
0
During the defrosting, the outdoor unit might generate some steam. It is caused by fast defrosting, which is not a
performance failure.
0
Upon the completion of the defrosting process, the heating operation is resumed.
[Methods of Maintenance]
The air conditioner must be turned off power before the maintenance is to be carried
out.
Before the season of operation

if the screen is very dirty, please use lukewarm water (about
86°F or 30'C) to clean it. Air it dry after the cleaning.
Check if the machine is
properly grounded.
Note:
• Do not use boiling water to clean the screen.
• Do not bake the screen dry over a fire.
• Do not exert too much force in pulling and stretching the screen.
Install the air filter screen.
Check if the air filter is clean.
To operate the air conditioner without the air filter screen on will cause the interior of the
machine dirty which might lead to poor performances or damages to the units.
Connect to the power source.
Clean the air conditioner
Put batteries in the remote controller.
• Use a soft and dry cloth to rub the air conditioner,
or use a vacuum cleaner to dean it.
• If the air conditioner is very dirty, use a piece of
cloth and soak it with neutral home-use detergent
to do the cleaning.
