NOTE
● 12 hours preheating is imperative after turn on the power
switch. Please do not shut down the power when the unit is
supposed to stop running in 24h or shorter time. (This is to
warm the crankcase heat box to avoid compulsive start of
condenser.)
● Pay attention not to block the air inlet and outlet. Blocks may
decrease the e󰀩ciency of the unit or startup the protector,
which will stop running.
● Operate the switches and push buttons with an insulated stick
(such as a closed ball-point pen) to avoid touching of live
parts.
3. OPERATION RANGE
Use the system in the following temperature for safe and e󰀨ective
operation. The Max operation temperature for the air conditioner.

NOTE
1. If the above operating conditions cannot be met, the safety
protection function may be triggered and the air conditioner
may malfunction.
2. When the unit operates in "cooling" mode in a relatively
humid environment (relative humidity higher than 80%),
condensation may occur on the surface of the IDU and water
may drip. In this case, turn the air guide to the maximum air
outlet position and set the fan speed to "High".
4. OPERATION AND PERFORMANCE
4.1 Protection Equipment
This Protection Equipment will enable the Air Conditioner to stop
when the Air Conditioner is to be directed running compulsively.
When the Protection Equipment is activated, the Operation Indicator
still lights while the Air Conditioner is not running. But the Check
Indicatior Lights.
The protection equipment may be activated in following conditions:
■ Cooling Operation
● The air inlet or air outlet of outdoor unit is blocked.
● Strong wind is Continuously blowing to the air outlet of the
outdoor unit.
■ Heating Operation
● Too much dust and rubbish adhere to the dust lter in the
indoor unit
● The air outlet of indoor unit is choked
NOTE
When the protection equipment starts, please shut down the
manual power switch, and restart operation after problem is
solved.
4.2 About power cut
● If power is cut during operation, stop all the operation immediately.
● Power comes again. The lamp on the display panel of indoor unit
ashes. And then unit will auto-restart.
● Mishandling in operation:
If mishandling happens because of lighting or mobile wireless,
please shut o󰀨 the manual power switch, and turn on again, then
push the ON/OFF button.
4.3 Heating capacity
● The heating operation is a heat-pump process that heat will
be absorbed from outdoor air and released in doors. Once the
outdoor temperature is decreased, heating capacity decreased
corredpindingly.
● Other heating equipment is suggested to be used together when
outdoor temperature is too low.
● In some extreme cold upland that buy another inddoor unit
equipped electrical heater will obtain better performance. (Refer to
indoor unit owner’s manual for details)
NOTE
1. The motor in Indoor Unit will continue running for 20~30 seconds
for to remove residual heat when the Indoor Unit recoeiving OFF
command during heating operation.
2. If the air conditioner malfunction occurs because of disturb,
pleasereconnect the air conditioner to power, then turn on it again.
4.4 Three-minute protection feature
● A protection feature prevents the air conditioner from being
activated for approximately 3 minuites when it restarts
immediately after operation.
