SET UP & USE
REFRIGERANT PIPING
CONNECTION
When connecting refrigerant piping, do not
let substances or gases other than the
specified refrigerant enter the unit. The
presence of other gases or substances will
lower the unit's capacity and can cause
abnormally high pressure in the refrigeration
cycle. This can cause explosion and injury.
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 16.5 feet (5 meters)
North America, the standard pipe length is 25'
(7.5m). A minimum pipe run of 10' (3 meters)
is required to minimize vibration & excessive
noise.

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.
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.

Step 2: Remove burrs
Burrs can affect the air-tight seal of
refrigerant piping connection. They must
be completely removed.
1. Hold the pipe at a downward angle to
prevent burrs from falling into the pipe.
2. Using a reamer or deburring tool,
remove all burrs from the cut section of
the pipe.
Step 3: Flare pipe ends
Proper flaring is essential to achieve an
airtight seal.
1. After removing burrs from cut pipe,
seal the ends with PVC tape to prevent
foreign materials from entering the
pipe.
2. Sheath the pipe with insulating
material.
3. Place flare nuts on both ends of pipe.
Make sure they are facing in the right
direction, because you can't put them
on or change their direction after
flaring.
