NOTES FOR USAGE
The conditions under which unit cannot normally run
Within the temperature range provided in following table, the air conditioner may
top running and other anomalies may arise.
Cooling
Heating
Note: Unit 1 (T1) and Unit 3 (T3) refer to ISO 5151.
•
When the temperature is too high, the air conditioner may activate the
automatic protection device, so that the air conditioner could be shut down.
•
When the temperature is too low, the heat exchanger of the air conditioner
may freeze, leading to water dripping or other malfunction.
•
In long-term cooling or dehumidification with a relative humidity of above
80 % (doors and windows are open), there may be water condenses or
dripping near the air outlet.
Notes for heating
•
The fan of the indoor unit will not start running immediately after the heating
is started to avoid blowing out cool air.
•
When it is cold and wet outside, the outdoor unit will develop frost over
the heat exchanger which will increased the heating capacity. Then the air
conditioner will start defrost function.
•
During defrost, the air conditioner will stop heating for about 5–12 minutes.
•
Vapour may come out from the outdoor unit during defrost. This is not a
malfunction, but a result of fast defrost.
•
Heating will resume after defrost is complete.
Notes for turning off
•
When the air conditioner is turned off, the main controller will automatically
decide whether to stop immediately or after running for dozens of seconds
with lower frequency and lower air speed.
