WARNING
CAUTION
WARNING
Incorrect handling can result in death or serious injury.
Incorrect handling can result in bodily injury and/or structure damage.
❈
See the Installation Manual that came with the outdoor unit for installation instructions.
CAUTION
Only a dealer or qualified technician should
perform installation.
¡Improper installation may result in refrigerant gas leakage
and equipment damage.
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.
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.
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.
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.

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 field-
supplied 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.)
