Main cause for gas leakage is due to defect in flaring work. Carry out the correct flaring work by
using the following procedures.

1. Use the piping kit accessory or the pipes

purchased locally.

2. Measure the distance between the indoor and

the outdoor unit.

3. Cut the pipes a little longer than measured

distance.

4. Cut the cable 1.5 m (5.0 ft) longer than the pipe

length.

1. Completely remove all burrs from the cut cross

section of pipe/tube.

2. Put the end of the copper tube/pipe in a

downward direction as you remove burrs in
order to avoid dropping burrs into the tubing.

1. Remove flare nuts attached to indoor and

outdoor unit, then put them on pipe/tube having
completed burr removal.
(not possible to put them on after flaring work)

1. Carry out flaring work using flaring tool as

shown below.

2. Firmly hold copper pipe in a bar in the

dimension shown in the table below.
