(1) Connect the refrigerant pipes (
1
and
2
) to field
refrigerant pipe.
(2) Wrap the accessory pipe insulation (
3
and
4
)
around the flare connection.
(3) Apply sealing material (field-supplied) at the
refrigerant pipe hole to prevent air leakage
If air leakage occurs, it may cause decreasing
performance or condensation.
Perform the piping work with the accessory L-shaped condensate pipe in order to adequately drain water. Do
not create an upper-slope or rise for the condensate piping since drain water can flow back to the indoor unit
and leakage into the room will occur. Especially, pay attention to the position of the cable band and applying
adhesive.
(1) Determine the drain-up height. The height can be adjusted according to the following figure.
(2) Connect the condensate hose (
2
), L-shaped condensate pipe (
3
) to the drain-up mechanism (
1
) by
hose band (
4
).
(Tightening Torque: 1.8 to 2.5 lbf-ft (2.5 to 3.4 N-m))
(3) Connect the field condensate pipe to the L-shaped condensate pipe (
3
) with a hose band (
5
).
(Tightening Torque: 1.8 to 2.5 lbf-ft (2.5 to 3.4 N-m))
(4) Insulate around the condensate pipe using pipe insulation (
7
) and insulations (
8
and
9
) as
follows. For the pipe insulation (
7
), wrap the vinyl tape (field-supplied) around it in order to prevent
condensation.
Additionally, perform the insulation work for the field condensate pipe.
(5) Cover the gap around the cap by insulation (
10
) after the L-shaped condensate pipe (
3
) runs through
the cap.
Be sure to apply the PVC (Polyvinyl chloride) adhesive (field-supplied) completely around the PVC pipe
connection. Securely connect the pipes at the following
A
and
B
in order to prevent water leakage. (Securely
fix the pipe connection at
C
using the cable band. Do NOT use adhesive.) Create 1/25 ~ 1/100 of a down-slope
ratio for the PVC piping.

Fix the upper-most part of L-shaped
condensate pipe so as not to apply
excessive force to condensate hose.
Otherwise, the condensate hose
may deform causing water leakage.
