7.2. Checks before setting in place
• Before installing the front panel, make sure the indoor unit is square with the
ceiling opening (or parallel to the angle between the wall and the ceiling).
• Check that the 4 points where the front panel will be secured are in contact with
the ceiling surface (see Fig. 7-2).
• Check that the insulation for the refrigerant pipes, drainage pipes, etc. is in place
and that wiring connections and arrangements are complete.
7.3. Installing the grille
• Open the intake grille by pressing on the place marked Push, and remove the air
filter.
• Remove the screw cover in the middle of the blower.
• Open the upper and lower flaps on the indoor unit completely.
• Hook the temporary holding tabs on the front panel to the hooks on the indoor unit
(see Fig. 7-3).
• Adjust the front panel so that it fits properly in the angle between the ceiling and the
wall, and install the securing bolts
and right, leaving them slightly loose.
• Next tighten the securing bolts
• Finally tighten the securing bolts
• At this point, make sure there are no gaps between the indoor unit and the front
panel, and between the front panel and the ceiling surface. If there are gaps, the
wind may come in and it may cause water to drip (see Fig. 7-4).
* Tighten the securing bolts
Caution:
When tightening the securing screws 2 and 3 , tighten them at a torque of
2.7 N•m (2.0 ft•lbs) or less. Never use an impact screwdriver.
• It may result in parts damage.
• Replace the air filter and screw cover, and press the intake grille on the place
marked Push until you hear it snap into place.
7.4. Checks after installing (Fig. 7-4)
• Check that there are no gaps between the indoor unit and the front panel, and
between the front panel and the ceiling surface. If there are gaps, the wind may
come in and condensation may result.
• Check that the air filter is in place.
