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 pur-
chased 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 down-
ward direction as you remove burrs in order
to avoid to let burrs drop in the tubing.
Flaring work

shown below.
Firmly hold copper tube in a bar(or die) as in-
dicated dimension in the table above.
Check
- Compare the flared work with figure below.
- If flare is noted to be defective, cut off the
flared section and do flaring work again.
