Before Operation - Hisense 12K Care, Use And Installation Instructions

Before Operation

●Supply electrical power to system for approximately 12 hours before start-up after long 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 higher than 50℃, it will cause damage to plastic parts.
●When the system is started after a shutdown longer than approximately 3 months, it is recommended that the
system be checked by your service contractor.
●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.
1.Special remarks
●
3 minutes protect after compressor stop
For protect compressor, there are at lest 3 minutes stopping after compressor stop.
●
5 minutes protect
Compressor must run 5 minutes at least once running. In the 5 minutes, compressor will not stop even the
room temperature reach the setting point unless you use remoter to turn off the unit(all indoor unit be turned
off by user).
●
Cooling operation
The fan of the indoor unit will never stop running. It remains running even if the compressor stops working.
●
Heating operation
Since the air conditioner carries out the heating operation by drawing on the heat of the outside air (through
heating pump), the heating capacity may decrease if the temperature outside the room is too low. If the heating
effect is not so satisfying, use some other heating device together.
●
A nti-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.
●
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 high enough temperature. That is because cold air prevention system
is operating.
●
Defrosting
When the outdoor temperature is too low, frost or ice may form in 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),a few minutes later, the
defrosting is over, and the heating operation restarts.
●
Blow out the survival heating air
When stop the air conditioner in normal operation, the fan motor would run in low speed for a while to blown
out the survival heating air.
●
Self Recovery of Power Break
When the power supply is recovered after break, all preset are still effective and the air-conditioner can run
according to the original setting.
