The following events may occur during normal operation.
1. Compressor Protection
The compressor will not restart for 3 to 4 minutes after it turns off. This prevents rapid cycling of the compressor.
2. Indoor Fan Operation
The unit is designed not to reduce the possibility of blowing cold air in the HEAT mode during one of the three
conditions and the set temperature has not been reached.
a) Initial start up - indoor coil temperature is too low.
b) Defrost function..
c) Indoor coil temperature is too low.
Defrost function:
Frost may be generated on the outdoor unit during the heat cycle if the outdoor temperature is low and humidity
is high. When this occurs the heat pump will stop the heating operation and start defrosting automatically.
The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of
frost buildup on the outdoor unit.
3. Mist blowing from the indoor unit
A mist may be generated, in a high humidity environment, due to a large temperature difference between air Inlet
and air outlet while in the COOL mode. It may be necessary to raise the set temperature to reduce this condition.
4. Low noise (Indoor Unit)
You may hear a low hissing sound when the compressor is running or has just stopped running. This sound is
the sound of the refrigerant flowing or stopping. You may also hear a low noise sound when the compressor is
running or has just stopped. This is caused by expansion and contraction of the plastic parts in the unit during
temperature changes.
A noise may be heard due to the louver returning to its original position when the unit is first turned on.
5. Dust blowing from the indoor unit.
This is a normal condition when the air conditioner has not been used for a long time or initial start up.
6. Fan cycling - HEAT or COOL modes.
In the cooling mode, indoor fan runs continuously at the selected speed: High, Medium, Low or Auto.
In the heating mode, the indoor fan will continue to run until the indoor coil temperature and the room
temperatures are satisfied.
If the compressor stops because the room temperature is satisfied, the indoor fan will continue to run for
approximately 2 minutes.
This High Efficiency unit is designed to maintain the selected room temperature by slowing the compressor and
refrigerant flow to the indoor unit to reduce the energy consumed by starting the compressor.
7. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity (higher
than 80%). Adjust the horizontal louver to the maximum air flow and select the HIGH fan speed.
8. Heating mode
The heat pump produces heat from the outdoor unit and releases it via the indoor units coil during the heating
operation. When the outdoor temperature falls, heat drawn in by the heat pump decreases accordingly.
At the same time, the heat load increases due to a larger difference between indoor and outdoor temperatures.
If a comfortable temperature can't be achieved by this unit during colder outdoor temperatures, we suggest you
use a supplemental heating device.
9. This unit is not intended as a primary heating source. The air conditioning mode provides area cooling.
10. Auto-restart function
After a power outage and the power is restored, the unit restarts automatically at all previous settings.
11. Lightning or a car wireless telephone operating nearby may cause a malfunction.
Turn the unit off with the remote and at the breaker. Wait 3 minutes and turn the power on and restart using the
remote.
12. To read room temperature set mode to fan.
