Safety Precautions
¡Thoroughly read the following “Safety Precautions” to ensure proper installation. ¡Observe the following important safety precautions at all times.
¡Hazards that can occur from incorrect handling are classified by the symbols below:
WARNING Incorrect handling can result in death or serious injury.
CAUTION Incorrect handling can result in bodily injury and/or structure damage.
WARNING
Only a dealer or qualified technician should perform installation.
¡Improper installation may result in refrigerant gas leakage and equipment damage.
Properly install all parts according to the instructions in the Installation Manual.
¡If the wrong twinning pipe or wrong size connecting pipe is used, air conditioning performance will suffer.
Do not make any modifications or alterations. Consult your dealer for repair.
¡Improper installation may result in water leakage, electric shock, or fire.
In the event of a refrigerant leak, thoroughly ventilate the room.
¡If refrigerant leaks and comes in contact with an open flame, toxic gases will be generated.
When installing or relocating the unit, check that no substance other than the specified refrigerant (R410A) enters the refrigerant circuit.
¡Any presence of foreign substance or air can cause abnormal pressure rise or explosion.
After installation, check for a refrigerant leak.
¡If leaked refrigerant comes in contact with a heat source, such as a fan heater, stove, or electric grill, toxic gases will be generated.
CAUTION
Properly dispose of packing materials.
¡Plastic bags can pose suffocation and choking hazards: keep them out of the reach of children. Tear the plastics bags before disposing of them.
Do not touch the refrigerant pipes and refrigerant circuit components with bare hands during and immediately after operation.
¡During or immediately after operation, certain parts of the unit such as pipes and compressor may be either very cold or hot, depending on the state of the refrigerant in the unit at the time. To reduce the risk of frostbites and burns, do not touch these parts with bare hands.
See the Installation Manual that came with the outdoor unit for installation instructions.

2.Selecting the Correct Size Refrigerant Pipes and Using the Twinning Kit
(1)Pipe size
1 Field-supply the pipes to be connected to the kit. 2 Choose the correct size pipe using the table
below. Connect the fieldsupplied pipe to the twinning kit for the sizes in the table that are marked with an asterisk (*).
3 If the pipe was cut with a pipe cutter, remove the burrs and eliminate foreign materials before connecting.
On the low-pressure side, the twinning kit connects to the field-supplied pipes inside the outdoor unit.
The distributor on the low-pressure side must be placed in the outdoor unit that has a larger capacity index of the two, regardless of the relative positions of the outdoor units or their addresses.
If the distributor is placed in the outdoor unit that has a smaller capacity, refrigerant will not be properly distributed and compressor failure may result.
( If outdoor units that have the same capacity are used in combination, the distributor can be placed in either outdoor unit.)
