Refrigerant piping work

Tightening flare connection part

ffCheck that the flaring is properly made.

ffAlign the center of the piping and sufficiently tighten the flare nut with fingers. Then, tighten the flare nut with torque wrench until the wrench clicks. When tightening the flare nut with torque wrench, ensure the direction for tightening follows the arrow on the wrench.

ffMake sure to use ester oil to coat the flare connection part.

• Blowing nitrogen gas should be done when brazing the pipe. CAUTION • Make sure to use the provided flare nut

•Make sure that there are no cracks when bending the pipe.

•Do not fasten the flare nut with excessive strength.

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

ffConnect the drain hose by inserting the extension drain hose to the drain connection port tightly. ffInsulated the extension drain hose, then fix it with a cable tie or a tape.
