Before Operation
Before Operation
ACAUTION
• Supply electrical power to system for approximately 6 hours before start-up after long time shutdown.
• Do not start the system immediately after power supply, it may cause a compressor tailure, because the
compressor is not heated well.
• Make sure that the outdoor unit is not covered with snow or ice. lt covered, remove it by using hot water
(approximately 50
º
C). lt the water temperature is more than 50
º
C, it will damage the plastic parts.
• When the system is started after a long time shutdown ot 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 ot time. lt the main switch is not turned
OFF, electricity is consumed because the oil heater is always energized during compressor stopping.
1.Special remarks
• 3 minutes protection after compressor stop
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 at least for 5 minutes once it starts running. In this 5 minutes, compressor will not stop
even it the room 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 tan of the indoor unit will never stop running during the cooling operation. lt remains running even if the
compressor stops working.
• Heating operation
Heating capacity depends on externa! factors like outdoor unit temperature. Heating capacity might decrease if
outdoor ambient temperature is too low.
• Anti-freezing tunction during cooling
When the temperature of the air from the indoor outlet is too low, the unit will run for sorne time under the tan
mode, to avoid frost or ice forming in the indoor heat exchanger.
• Cold air prevention
In several minutes after the heating mode is started, the tan ot the indoor unit will not run until the heat
exchanger of the indoor unit reaches a certain temperature to prevent cold draft.
• Defrosting
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 sametime the
tan in the indoor unit stops (or runs at a very low speed in sorne cases), to prevent cold draft. After defrosting
is over, the heating operation and tan speed restarts.
• Blowing out the residual heating air
When air conditioner is stopped during normal operation, the tan motor would run with low speed for a while to
blow out 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.
