Featuresofyournewairconditioner

• CoolSummerOffer

On those hot sweltering summer days and long restless nights, there is no better escape from the heat than the cool comforts of home. Your new air conditioner brings an end to exhausting hot summer days and lets you rest. This summer, beat the heat with your own

air conditioner.

• CostEfficientSystem

Your new air conditioner not only provides maximum cooling power in the summer, but can also be an efficient heating method in the winter with the advanced“Heat pump”system. This technology is up to 300% more efficient than electrical heating, so you can further reduce its running cost. Now, meet year-round needs with one air conditioner.

• Flexibleinstallation

Duct type air conditioner is designed to be slimmer and offers different solutions for any shape room allowing for specific air flow requirements. Also, the air intake can be set up on either the bottom or rear of the unit, so there is more flexibility in installation.

For easy future reference, write the model and serial number down. You will find your model number on the bottom right side of the air conditioner.

Here are some tips that you would follow when using your air conditioner.

TOPIC	RECOMMENDATION
Cooling	• Ifcurrentoutsidetemperaturesaremuchhigherthantheselectedindoor
	temperature, it may take time to bring the inner temperature to the desired coolness.
	• Avoiddrasticallyturningdownthetemperature.
	Energy is wasted and the room does not cool faster.
Heating	• Sincetheairconditionerheatstheroombytakingheatenergyfromoutdoorair,the
	heating capacity may decrease when outdoor temperatures are extremely low. If you
	feel the air conditioner insufficiently heats, using an additional heating appliance in
	combination with the air conditioner is recommended.
Frost&De-ice	• WhentheairconditionerrunsinHeatmode,duetotemperaturedifferencebetween
	the unit and the outside air, frost will form.
	If this happens:
	- The air conditioner stops heating.
	- The air conditioner will operate automatically in De-ice mode for
	10 minutes.
	- The steam produced on the outdoor unit in De-ice mode is safe.
	No intervention is required; after about 10 minutes, the air conditioner operates again
	normally.
	The unit will not operate when it starts to de-ice.
Fan	• Fanmaynotoperateforabout3~5minutesatthebeginningtopreventanycold
	blasts while the air conditioner is warming up.
Highindoor/outdoor	• Ifbothindoorandoutdoortemperaturesarehighandtheairconditionerisrunningin
temperatures	Heat mode, the outdoor unit’s fan and compressor may stop at times. This is normal; wait
	until the air conditioner turns on again.
Powerfailure	• Ifapowerfailureoccursduringtheoperationoftheairconditioner,theoperating
	immediately stops and unit will be off. When power returns, the air conditioner will run
	automatically.
Protectionmechanism	• Iftheairconditionerhasjustbeenturnedonafteroperationstopsorbeingplugged
