To fasten the flare nuts, apply specified torque.
• W hen brazing, must be cool the pipe by wet cloths after removing the insulation tube and the cover plate.
• W hen brazing the gas tubing, cool the tubing with dampened shopcloths as you work, as shown in the
figure below, to protect the unit’s thermistor from the heat generated by brazing.

• The Type 200 indoor unit comes with a tube connector
that is for liquid tubing.
Configure as shown in the illustration and connect it.
When flaring the tube, put the flare nut onto it first and then
flare it.
Remove the ø12.7 flare nut
from the liquid tubing of the
indoor unit and use it.

• Pipe insulation must be made after leak detection for tubing connection area was performed.
• Be sure to insulate both the gas tubing and liquid tubing.
In addition, wrap the supplied insulation material around the tubing joints, and fasten in place
with vinyl tape or other means.
Failure to insulate the tubing may result in water leakage from condensation.
• Plug all gaps at tube through-holes in the unit with insulation or a similar substance to prevent
air leakage.
9-4. Installing the Drain Piping
(1) Prepare standard hard PVC pipe (O.D. 32 mm) for the drain and
use the supplied drain socket to prevent water leaks.
The PVC pipe must be purchased separately.
When doing this, apply adhesive for the PVC pipe at the
connection point.
(2) If connecting a drain socket (supplied) to the threaded drain port,
first wrap the drain port threads with sealing tape, then connect
the joint. (Fig. 1-27)
(3) Ensure the drain pipe has a downward slant (1/100 or more).
(See the Fig. 1-28)
(4) The drain pipe with a trap should be installed away from the
indoor unit.
(5) Do not forcibly install the drain pipe to the indoor unit tubing.
If forcibly installed, it may result in water leakage.
(6) The drain pipe should be fixed at the nearest of the indoor unit.
Failure to do so may result in water leakage.
(7) Do not attach any air purge equipment.
If attached, drain water may result in splashing out of the drain
pipe.
(8) When the drain piping is completed, perform the water leak test
and check for a water leak.
If detected, it may result in water leakage or condensation.
(9) When the drain piping is completed, perform the drainage test
if the water drains smoothly.
If not draining smoothly, it may result in water leakage or
condensation.
(10) When the drain piping work is finished securely, wrap the
insulation material around the indoor side drain pipe.
At this time, do not wrap together with the refrigerant tubing.
If wraped together, the drain pipe is lifted and water drainage will
not be operated.
Coincidentally, the water comes out of the drain pan and it can
lead to water leakage.

Note:
Since the drain trap area easily accumulates
the dust inside the drain pipe, necessarily
install the plug in order to clean out the drain
trap.
