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 pipes field-
supplied 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.)
