Installation Procedure
Nitrogen flushing welding
• When welding the refrigerant pipes, flush them with nitrogen
gas as shown in the picture.
• If you do not perform nitrogen flushing when welding the
pipes, oxide may form inside the pipe. It can cause the damage
of the important parts such as compressor and valves etc.
• Adjust the flow rate of the nitrogen flushing with a pressure
regulator to maintain 0.05 m²/h (0.54ft²/h) or less.

Direction of the pipe when welding
• Direction of the pipe should be headed downward or in a
sideways when welding.
• Avoid welding the pipe with pipe direction heading upward.
CAUTION
• When you test gas leakage after welding the pipes, use a
designated solution for gas leakage detection. If you use the
detection solution that includes sulfuric ingredient, it may
cause corrosion to the pipes.
Cutting or flaring the pipes
1 Make sure that you prepared the required tools.
– Pipe cutter, Deburring tool, flaring tool and pipe holder, etc.
2 If you want to shorten the pipe, cut it with a pipe cutter
ensuring that the cut edge remains at 90° with the side of the
pipe.
– Refer to below illustrations for correct and incorrect
examples of cut edges.

3 To prevent a gas leak, remove all burrs at the cut edge of the
pipe using a Deburring tool.
4 Carry out flaring work using flaring tool as shown below.

CAUTION
• If foreign matters or burrs are not removed after cutting pipe,
refrigerant gas may leak.
• If foreign matters enter inside the pipe, important interior
parts of the unit may get damaged or product efficiency will be
reduced. So, the direction of pipe should be downward during
pipe cutting or flaring.
