6.1 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). A minimum pipe run of 3 metres is
required to minimise vibration & excessive noise.
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).
Refer to the table below for specifications on the maximum length and drop height of piping.

6.2 CONNECTION INSTRUCTIONS – 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. For R32/R290 refrigerant models, 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.
