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.)
