6. Indoor unit installation
• Hook the indoor unit onto the upper portion of
installation plate. (Engage the two hooks of the rear
top of the indoor unit with the upper edge of the
installation plate.)
Ensure the hooks are properly seated on the
installation plate by moving it left and right.
7. Connecting the pipings to the indoor unit.
• Align the center of the pipings and sufficiently tighten
the flare nut with fingers.
• Finally, tighten the flare nut with torque wrench until
the wrench clicks.
When tightening the flare nut with torque wrench,
ensure the direction for tightening follows the arrow
on the wrench.
8. Wrap the insulation material around the
connecting portion.
CAUTION: Take care to arrange the pipings, drain
hose and cables as the picture on page 25
for inserting it into the indoor unit and
refixing the tubing holder easily.
9. Insulation of connecting tubing
• Because capillary tubing is installed in the outdoor
unit, both the liquid and gas side tubes of this air
conditioner become cold or hot(Heat pump model).
Therefore, to prevent heat loss and wet floors due to
dripping of condensation water, both tubes must be
well insulated with proper insulation material.
The thickness of the insulation material should be a
Min. 8mm(5/16").
