PREPARATION BEFORE USE

Before using the air conditioner, be sure to check and preset the following.

• Remote Control presetting

The remote control is NOT preset as Cooling Only Air Conditioner or Heat Pump by manufacturer.
Each time the remote control batteries are replaced, the Cooling indicator and Heating indicator will flash
alternately on the remote control LCD.
The user can preset the remote control depending on the air conditioner type purchased as follows:
Pressing any button when flashes, Heat Pump is set.
Pressing any button when flashes, Cooling Only is set.
If you don’t press any button within 12 seconds, the remote control is preset as Heat Pump automatically.

Note:
If the air conditioner you purchased is a Cooling Only one, but you preset the remote control as Heat
Pump, it doesn’t matter. But if the air conditioner you purchased is a Heat Pump one, and you preset the
remote control as Cooling Only, then you CANNOT preset the Heating operation with the remote

control.

• Back-light function (optional)

Pressing any button of the remote control for about 2 seconds, the back-light turns on. Once the button is released,
it automatically turns off after 10 seconds.

Note: Back-light is an optional function.

• Auto Restart Presetting

The Auto restart function is not preset by the manufacturer. To set the auto restart function, press the Emergency
button (ON/OFF) on the indoor unit for at least 5 seconds. A buzz sound will signal that the auto restart function is

To cancel the auto restart function, press the Emergency button (ON/OFF) on the indoor unit for at least 5 seconds.
A buzz sound will signal that the auto restart function is cancelled and the air conditioner is in standby.

SAFETY PRECAUTIONS

Be sure not to do the following.

•

It is harmful to your health if the cool air reaches you for a long time. It is
advisable to let the air flow be deflected to all the room.

•

Prevent the air flow from reaching the gas burners and stove.

•

Do not touch the operation buttons when your hands are wet.

Pay attention to such a situation.

•

Do not repair the appliance by yourself. If this is done incorrectly, it may
cause an electric shock, etc.

Be sure to follow this instruction.

•

Do not put any objects on the outdoor unit.

Earthing is essential.

•

It is the user’s responsibility to have the appliance be earthed according to
local laws by a qualified technician.

Warning: Incorrect handling could cause a serious hazard, such as
death, serious injury, etc.

•

Use correct power supply in accordance with the rating plate
requirement. Don't use any extension cord for power supply. Otherwise,
serious faults or hazard may occur or a fire may break out.

•

Keep the power supply circuit breaker or plug from dirt. Connect the
power supply cord to it firmly and correctly, lest an electric shock or a fire
break out due to insufficient contact.

•

Do not use the power supply circuit breaker or pull off the plug to turn it
off during operation. This may cause a fire due to spark, etc.

•

Do not twist, pull or press the power supply cord, lest the power supply
cord be broken. An electric shock or fire is probably caused by a broken
power supply cord.

•

Never insert a stick or similar obstacle in the unit. Since the fan rotates at
high speed, this may cause an injury.

•

Turn off the appliance with remote control first before cutting off power
supply if malfunction occurs.

How to Purge Air Tubes

•

Unscrew and remove caps from 2 and 3-way valves.

•

Unscrew and remove cap from service valve.

•

Connect vacuum pump flexible hose to the service valve.

•

Start the vacuum pump for 10-15 minutes until it reaches an absolute vacuum of 10 mm Hg.

•

With the vacuum pump still running close the low pressure knob on the vacuum pump manifold. Then stop the
vacuum pump.

•

Open the 2-way valve ¼ turn, then close it after 10 seconds. Check tightness of all joints using liquid soap or an
electronic leak detector.

•

Turn the 2 and 3-way valves stem. Disconnect the vacuum pump flexible hose.

•

Replace and tighten all valve caps.

NOTES:

•

Please read this manual before installing and using the appliance.

•

Do not let air enter the refrigerating system or discharge refrigerant when moving the air conditioner.

•

When charging refrigerant into the system, make sure to charge in liquid state. Otherwise, chemical composition of
refrigerant (R410A) inside the system may change and thus affect performance of the air conditioner.

•

Test run the air conditioner after finishing installation and record details of operation.

•

Type of fuse used on indoor unit control for 7 K, 9 K, 12 K is 50 T, with rating 2.5 A,T,250 V.

•

For 18 K, 22 K, 24 K models use 5 A, T, 250 V.

•

The fuse for the whole unit is to be provided by the user according to the current at maximum power input or use
another over-current protective device instead.

•

Only the air conditioner can be connected to the power line.

•

The power connection for the air conditioner has to be done at the main power distribution which has to be of a low
impedance.

•

In order to ensure the suitability of the equipment for connection, the user should consult with the supply authority,
if necessary, that the service current capacity at the interface point is sufficient for the equipment.

•

Refer to the rating plate of the equipment for power consumption details.

•

If the supply cord is damaged, it must be replaced by the manufacturers After-Sales Service or a qualified tecnician
in order to avoid a hazard.

•

Accessibility to the plug must be guaranteed even after the installation of the appliance to disconnect it if necessary.
If this is not possible, connect the appliance to a double-pole switching device with contact distance of at least 3 mm
placed in an accessible position even after installation.

•

Please pay more attention to the details of 2-way and 3-way valve. Service valve: 7/16 inch for R410A model; and 1/
4 inch for R22 and R407C. Diameter of hexagon (inward): 4mm for R410A model; 5mm for R407C and R22.
