• When brazing, must be cool the pipe by wet cloths after removing the insulation
tube and the cover plate.
• When 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 rom the heat
generated by brazing.
• When brazing, be careful not to heat the electrical component box.
Doing so may cause the unit to be damaged.
• The type 200 indoor unit comes with a connection tubing 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.

• 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.
Installing the Drain Piping
1. Before Performing the Installation Drain Piping
(1) Prepare standard hard PVC pipe (O.D. 32 mm) for the drain and use the supplied drain bsocket to prevent water leaks.
The PVC pipe must be purchased separately.
When doing this, apply adhesive for the PVC pipe at the connection point.
See section "2. Installing the Drain Pipe"on page 1-12-2-1-6.
(2) Limitations of Drain Hose Connection
CAUTION
Do not make a trap in the middle of the supplied drain pipe.
Doing so will cause abnormal sound.
(3) Ensure the drain pipe has a downward slant (1/100 or more).
Correct
(4) The drain pipe with a trap should be installed away from the indoor unit.
(5) Do not attach any air purge equipment.
If attached, drain water may result in splashing out of the drain pipe.
(6) 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.
(7) 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.
(8) 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.
Consequently, the water comes out of the drain pan and it can lead to water leakage.
