Apply refrigerant oli at both inside and outsid of !tiare nut. Tighten it band tight 3-4 tums then tighten it.
lise torque specified in Table 1. (Too much force may damage flare nut, causing gas leakage).
Check piping joints for gas leakage. 'mutate piping as shown in Fig. below.
Cover joint of gas piping and insulator (7) with seal.

INSTALLATION OF WATER
DRAINAGE
PIPE
(1) install
water drainage pipe
Pipe dia, shall be equal or larger than
that
of unit piping.(pipe of polyethylent; size: 25mm; 0.D:32mm)
Drain pipe should be short, with a downward slope at least 1/100 to prevent air bag from happening.
If downward slope can't be made, take other measures to lift it up.
Keep a distance of 1-1.5m between suspending brackets, to make water hose straight.
1-1.5m

-
Siepe over 1/100
o
Use the self-provided stiff pipe and clamp
with unit. Insert water pipe into water plug until it reaches the white
tape. Tighten the clip until head of the screw is less than 4mm from hose.
Wind the drain hose to the clip using seal pad
.
Insulate drain hose in the room.
