3-23. Removing and Installing the Grille

Basically, these models can be installed and wired without
removing the grille. If access to any internal part is needed,
follow the steps as given below.
How to remove the grille
(1) Open the front panel until it is nearly horizontal, grasp the
sections near the front panel arms on both sides, and then
remove the panel by pushing the arms towards the outside
while pulling the panel towards you.
If the front panel is difficult to remove, grasp both ends of
it and lift it up slightly. Move it to the left and disengage the
left arm, then move it to the right and disengage the right
arm. (Fig. 3-82)
(2) Lift the anti-mold filter up slightly to disengage it from the
protrusions on the unit, and then pull downward to remove
the filter from the unit. (Fig. 3-82)
(3) Remove the 3 screws from the front of the unit and remove
the screw covers on the bottom surface. Then remove the
2 screws. (Fig. 3-83)
(4) Remove the screw on the right side cover plate and
remove the cover. (Fig. 3-83)
(5) Remove the lower flap by disengaging 4 pins of the lower
flap in order. (Figs. 3-84 and 3-85)
(The flap is so flexible that it can be easily removed.)
(6) Lift up the grille in the direction shown by the arrow and
pull the grille towards you to remove it. (Fig. 3-86)
How to replace the grille
(1) While aligning the top edge of the grille with the frame,
move the grille horizontally and insert the top and bottom
into the frame.
(2) Press the grille firmly with your hand to ensure no gap
exists between the frame and grille.
(3) Tighten the 6 screws. And fix the removed covers in place.
(4) Grasp the sections near the front panel arms on both
sides, and hold the front panel so that it is nearly
horizontal. Push the arm shafts towards the outside so that
they come into contact with the top of the indentations on
the right and left sides of the air conditioner. Then push
firmly until the arm shafts click into place. (Fig. 3-87)
(5) Remount the lower flap.
(In remounting the flap, it cannot be turned end for end
because the right and left pins of the flap differ in form.
(Fig. 3-85))
(6) Insert the top of the anti-mold filter, and then secure the
bottom of the filter with the protrusions on the unit.
(7) When closing the front panel, push the central part of the
front panel first and then press the bottom right and left
corners in place until you feel a click. (Fig. 3-88)

3-24. Shape the Indoor Side Tubing

(1) Arrangement of tubing by direction
a) Right or left tubing
Cut out the corner of the right/left frame with a hacksaw
or the like. (Figs. 3-89 and 3-90)
b) Right-rear or left-rear tubing
In this case, the corner of the frame need not be cut.
(2) To mount the indoor unit on the rear panel:
Hang the 3 mounting slots of the unit on the upper tabs
of the rear panel. (Fig. 3-91)

3-25. Wiring Instructions

General precautions on wiring
(1) Before wiring, confirm the rated voltage of the unit as
shown on its nameplate, then carry out the wiring closely
following the wiring diagram.
(2) Provide a power outlet to be used exclusively for each
unit, with a power supply disconnect and circuit breaker for
overcurrent protection provided in the exclusive line.
(3) To prevent possible hazards due to insulation failure, the
unit must be grounded.
(4) Each wiring connection must be done tightly and in
accordance with the wiring system diagram. Wrong wiring
may cause the unit to misoperate or become damaged.
(5) Do not allow wiring to touch the refrigerant tubing,
compressor, or any moving parts of the fan.
(6) Unauthorized changes in the internal wiring can be very
dangerous. The manufacturer will accept no responsibility
for any damage or misoperation that occurs as a result of
such unauthorized changes.
