CAUTION
Insulate both gas and liquid
tubes.
● To insulate tubes
(1) Wrap the flare nuts with the supplied white insulating tape.
(2) Wrap the flare nuts with the supplied flare insulator.
(3) Fill the clearance between the union insulator and flare insulator
with black insulating tape. Fasten both ends of the flare insulator
with the supplied vinyl clamps.
3-29. Installing the Drain Piping
(1) When rear-side drain piping is required bend the drain hose
attached to the indoor unit by 90° . Connect a drain pipe (field
supply) to the drain hose through the rear tubing outlet in the
rear panel. Use a hard PVC pipe (VP20) for the drain piping.
(2) Ensure that the drain pipe has a downward gradient of 1/100 or
more and that there are no water traps.
(3) Provide insulation for the drain pipe.
(4) After the drain piping is completed, pour water into the drain pan
to check that the water drains smoothly.
(5) Remove any dust or debris in the drain pan so that the pipe is
not clogged.
3-30. Installing the Remote Controller
A remote controller (optional wired remote controller) can
be mounted in the indoor unit (floor-standing type).
(1) Remove the cover of the optional wired remote controller.
(Fig. 3-68)
(2) Remove the front panel. Remove the screws and fixture.
(Fig. 3-69)
(3) Place the remote controller into the space in the unit as shown in
Fig. 3-69. Assemble the lead wires of the remote controller to its
rear side center and route them to the lead wire guide.
(4) Secure the fixture using the supplied screws.
To remove the cover from the remote controller, insert a
screwdriver between the cover and the controller as shown
in the figure above, and pry off the cover.
CAUTION
Water leaks may occur if the drain
pipes are connected inadequately.
