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).
For special tropical area, the maximum length of refrigerant pipe should not exceed 10 meters(32.8ft)
and no refrigerant can be added(For R290 refrigerant models).

Refrigerant 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. The pipe connection points
must be placed outside of room.
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. 5.1 for bad cut examples.
