## Refrigerant Lines Removal Note

### Nut joint type

1. Loosen the nut using two spanners, then remove the cooler pipe or hose.

### Block joint type

1. Disconnect the block joint type pipes by grasping female side of the block with pliers or similar tool and holding firmly, then remove the connection bolt or nut.

### Spring-lock coupling type

1. Set the SST.

2. While looking through the inspection hole of the SST, insert the protruding part of the SST until it makes contact with the cage section.

3. Use the SST to disconnect the male pipe or hose from the female by pulling the male pipe or hose.

  Note

  • The male pipe or hose can be disconnected easily from the female pipe by pulling from the male pipe or hose while maintaining the pressure of the protruding part of the SST.

## Refrigerant Lines Installation Note

1. When installing a new cooler pipe No.4 or cooler hose (LO), add a supplemental amount of ATMOS GU10 compressor oil into the refrigeration cycle.

Supplemental amount (approx. quantity)

  5 ml {5 cc, 0.2 fl oz}: Cooler pipe No.4
  10 ml {10 cc, 0.3 fl oz}: Cooler hose (LO)

2. Apply compressor oil to the O-rings and connect the joints.

3. Tighten the joints.

### Nut or block joint type

1. Tighten the nut or bolt of joint by hand.

2. Tighten the joint to the specified torque. If it is a nut joint, tighten the nut with a spanner and torque wrench.

3. Connect the block joint type pipes by grasping the female side of the block with pliers or similar tool and holding firmly, then tighten the connection bolt or nut with a torque wrench.

### Spring-lock coupling type

1. Connect the male pipe or hose by twisting it onto female pipe until the garter spring at the male pipe or hose is over the flared end of female pipe.

  Note
