Refrigerant Piping Connection

Note on Pipe Length

The length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominal efficiency is tested on units
with a pipe length of 5 meters (16.5ft).
Refer to the table below for specifications on the maximum length and drop height of piping.

Step 1: Cut pipes
When preparing refrigerant pipes, take extra care to cut and
flare them properly. This will ensure efficient operation and
minimize the need for future maintenance.
1. Measure the distance between the indoor and outdoor units.

2. Using a pipe cutter, cut the pipe a little longer than the
measured distance.
3. Make sure that the pipe is cut at a perfect 90° angle. Refer to
Fig. 6.1 for bad cut examples.
