- Use the piping kit accessory 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 in a
downward direction as you remove burrs in
order to avoid dropping burrs into the tubing.

outdoor unit, then put them on pipe/tube
having completed burr removal.

work)
