Before Operation
●
Supply electrical power to system for approximately 12 hours before start-up after long time shutdown.
●
Do
not
start
the
system immediately after power supply, it may cause a compressor failure, because the
compressor is not heated well.
●
Make sure that the outdoor unit is not covered with snow or ice. If covered, remove it by using hot water
(approximately 50
℃).
If the water temperature is more than 50
℃
, it will damage the plastic parts.
●
When the system is started after a long time shutdown of more than 3 months, it is recommended that the
system be checked by your service dealer.
●
Turn OFF the main switch when the system is stopped for a long period of time. If the main switch is not
turned OFF, electricity is consumed because the oil heater is always energized during compressor stopping.
Heating capacity depends on external factors like outdoor unit temperature. Heating capacity might decrease if outdoor ambient
temperature is too low.
●
Cold air prevention
In several minutes after the heating mode is started, the fan of the indoor unit will not run until the heat exchanger of the indoor
unit reaches a certain temperature to prevent cold draft.
●
When the outdoor temperature is too low, frost or ice may form on the outdoor heat exchanger, reducing
heating performance. When this happens, a defrosting system of the air conditioner will operate. At the same time the fan
in the indoor unit stops (or runs at a very low speed in some cases), to prevent cold draft. After defrosting is over, the heating
operation and fan speed restarts.
●
●
1. Special Remarks
●
To protect compressor, it will be continue to be off for at least 3 minutes once it has stopped.
●
5 minutes protection
Compressor must run
running. In this 5 minutes, compressor will not stop even if the room
at least for 5 minutes once it starts
temperature reaches the setting temperature point unless you use remote controller to turn off the unit (all indoor unit can be
turned off by user).
●
Cooling operation
The fan of the indoor unit will never stop running during the cooling operation. It remains running even if the compressor stops
working.
Anti-freezing function during cooling
When the temperature of the air from the indoor outlet is too low, the unit will run for some time under the fan mode, to avoid
frost or ice forming in the indoor heat exchanger.
Defrosting
Blowing out the residual heating air
Auto restart from Power Break
When the power supply is recovered after power break, all presets are still effective and the air-conditioner will run according to
the previous setting.
For more details, please refer to the Manual of Remote Controller.
2. Setting of Automatic Swing Louver
Do not adjust the air louver by hand, to avoid damage to the louver mechanism
.
Before Operation
●
Heating
operation
●
When
normal operation, the fan motor would run with low speed for a while to blow out
air conditioner is stopped during
residual
3 minutes protection after compressor stop
heating air.
