Refrigerant piping work
Pipe bending
1 Perform bending of the pipe using the bender which has a
specified bending radius.
2 Be sure to take full care to perform bending of the pipe
successfully at one time. Bending and unbending the pipe
more than twice makes the bending work increasingly
difficult.
3 You may use the spring inserted into the gas pipe instead
of the bender to bend the pipe.
4 When you bend the pipe using the spring, hold the pipe
with both hands to prevent any distortion, and secure a
minimum bending radius over 100mm.
Connecting the drain hose
