6.   Place flaring tool onto the form.
7.   Turn the handle of the flaring tool clockwise 

until the pipe is fully flared.

8.   Remove the flaring tool and flare form, then 

inspect the end of the pipe for cracks and 
even flaring.

Step 4: Connect pipes

When connecting refrigerant pipes, be careful 
not to use excessive torque or to deform the 
piping in any way. You should first connect the 
low-pressure pipe, then the high-pressure pipe.

MINIMUM BEND RADIUS

When bending connective refrigerant piping, 
the minimum bending radius is 10cm. See

 DO NOT USE EXCESSIVE TORQUE

Excessive force can break the nut or damage the refrigerant piping. You must not exceed torque 
requirements shown in the table above.

Instructions for Connecting Piping to 

Indoor Unit

1.   Align the center of the two pipes that you will 

connect. See 

Fig. 5.7

.

Indoor unit tubing

Flare nut

Pipe

2.   Tighten the flare nut as tightly as possible by 

hand.

3.   Using a spanner, grip the nut on the unit 

tubing.

4.   While firmly gripping the nut on the unit 

tubing, use a torque wrench to tighten the 
flare nut according to the torque values in the 

Torque Requirements

 table below. Loosen 

the flaring nut slightly, then tighten again.
