REFRIGERANT TUBE CONNECTION
Placement of outdoor unit
Anchor the outdoor unit with bolts and
nuts on a concrete or rigid mount.
.
Drain Joint Installation
If a drain elbow is used, the unit should be
placed on a stand which is taller
than 1.5”.
Fit the seal into the drain elbow, then insert the
drain joint into the base pan hole of the outdoor
unit, rotate 90 degrees to securely assemble.
Connect the drain joint with the extension drain
hose (locally purchased), to allow the water to
drain from the outdoor unit during heating
mode.

Refrigerant Tube Connection
1. Flaring work
Main cause for refrigerant leakage
is due to defect in the flaring work.
Carry out correct flaring work
using the following procedure:
A: Cut the pipes and the cable.
1. Use the piping kit accessory or pipes
purchased locally.
2. Measure the distance between the indoor
and the outdoor unit.
3. Cut the pipes a little longer than the
measured distance.
4. Cut the
cable 60” longer than the pipe
length.
B: Burr removal
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.
