Features of your new air conditioner

• Cool Summer Offer

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.

• Cost Efficient System

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.

• Flexible installation

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.

Using your air conditioner

TIPS ON USING AIR CONDITIONER

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

TOPIC	RECOMMENDATION
Cooling	• If current outside temperatures are much higher than the selected indoor
	temperature, it may take time to bring the inner temperature to the desired
	coolness.
	• Avoid drastically turning down the temperature.
	Energy is wasted and the room does not cool faster.
Heating	• Since the air conditioner heats the room by taking heat energy from
	outdoor air, 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	• When the air conditioner runs in Heat mode, due to temperature difference
	between 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	• Fan may not operate for about 3~5 minutes at the beginning to prevent any
	cold blasts while the air conditioner is warming up.
High indoor/outdoor	• If both indoor and outdoor temperatures are high and the air conditioner is
temperatures	running in Heat mode, the outdoor unit’s fan and compressor may stop at
	times. This is normal; wait until the air conditioner turns on again.
Power failure	• If a power failure occurs during the operation of the air conditioner, the
	operating immediately stops and unit will be off. When power returns, the
	air conditioner will run automatically.
Protection	• If the air conditioner has just been turned on after operation stops or being
mechanism	plugged in, cool/warm air does not come out for 3 minutes to protect the
	compressor of the outdoor unit.

Cleaning the air conditioner

For the best performance from your air conditioner, clean it periodically. When cleaning, make sure to unplug from the unit for user’s safety.

MAINTAINING YOUR AIR CONDITIONER

If the air conditioner will not be used for an extended period of time, dry the air conditioner to maintain it in best condition.

1.Dry the air conditioner thoroughly by operating in Fan mode for 3 to 4 hours and disconnect the power plug. There may be internal damage if moisture is left in components.

2.Before using the air conditioner again, dry the inner components of the air conditioner again by running in Fan mode for 3 to 4 hours. This helps remove odors which may have generated from dampness.

Periodical checks

Refer to the following chart to maintain the air conditioner properly.

The checks and maintenance operations described are essential to guarantee the efficiency of the air conditioner. The frequency of these operations varies according to the characteristics of the area, the amount of dust, etc.

(1)The described operations should be performed more frequently if the area of installation is very dusty.

(2)These operations must always be performed by qualified personnel. For more detailed information, see the Installation Manual.

MAINTAINING YOUR AIR CONDITIONER

Internal protections via the unit control system

This internal protection operates if an internal fault occurs in the air conditioner.

Type	Description
Against cold air	The internal fan will be off to against cold air when the heat pump is heating.
De-ice cycle	The internal fan will be off to against cold air when the heat pump is heating.
Anti-protection of	The compressor will be off to protect internal battery when the air conditioner

Protect	The air conditioner does not start operating immediately to protect the com-
compressor	pressor of the outdoor unit after it has been started.

If the heat pump is operating in Heat mode, De-ice cycle is actuated to remove frost from an outdoor unit that may have deposited at low temperatures.

The internal fan is switched off automatically and restarted only after the de-ice cycle is completed.
