Connecting Pipes to the Indoor Unit

Connecting Pipes to the Indoor Unit

Preparation of Piping

Main cause of gas leakage is defect in flaring
work. Carry out correct flaring work in the
following procedure.

Cut the pipes and the cable.

• Use the accessory piping kit or the pipes

purchased locally.

• Measure the distance between the indoor and

the outdoor unit.

• Cut the pipes a little longer than measured

distance.

• Cut the cable 1.5m longer than the pipe length.

Burrs removal

• Completely remove all burrs from the cut cross

section of pipe/tube.

• Put the end of the copper tube/pipe to

downward direction as you remove burrs in
order to avoid to let burrs drop in the tubing.

Putting nut on

• Remove flare nuts attached to indoor and

outdoor units, than put them on pipe/tube
having completed burr removal.
(Not possible to put them on after flaring work)

Flaring work

• Carry out flaring work using flaring tool as

shown below.

Firmly hold copper tube in a bar(or die) as
indicated dimension in the table above.

Check

• Compare the flared work with figure.

• If flare is noted to be defective, cut off the

flared section and do flaring work again.
