DO NOT DEFORM PIPE

WHILE CUTTING

Be extra careful not to damage, dent, or

deform the pipe while cutting. This will

drastically reduce the heating efficiency

of the unit.

Step 2: Remove burrs

Burrs can affect the air-tight seal of refrigerant

piping connection. They must be completely

removed.

Hold the pipe at a downward angle to prevent

burrs from falling into the pipe.

Using a reamer or deburring tool, remove all

burrs from the cut section of the pipe.

Step 3: Flare pipe ends

Proper ﬂaring is essential to achieve an airtight

seal.

After removing burrs from cut pipe, seal

the ends with PVC tape to prevent foreign

materials from entering the pipe.

Sheath the pipe with insulating material.

Place flare nuts on both ends of pipe. Make

sure they are facing in the right direction,

because you can’t put them on or change

their direction after flaring. See

Fig. 5.3.

Remove PVC tape from ends of pipe when

ready to perform flaring work.

Clamp flare form on the end of the pipe.

The end of the pipe must extend beyond the

edge of the flare form in accordance with the

dimensions shown in the table below.

Place flaring tool onto the form.

Turn the handle of the flaring tool clockwise

until the pipe is fully flared.

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

Fig.5.6.

TORQUE REQUIREMENTS

Instructions for Connecting Piping

to Indoor Unit

Align the center of the two pipes that you will

connect. See Fig. 5.7

Indoor unit tubing Flare nut Pipe

Tighten the flare nut as tightly as possible by

hand.

Using a spanner, grip the nut on the unit

tubing.

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.

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.
