.2 Installation of the Main Body
Existing ceiling (which must be level)
1. Drill a 910 mm × 910 mm square hole into the ceiling based on the layout of the installation board (see
Figures 1, 2, and 3).
a. The center of the ceiling opening should match that of the unit.
b. Determine the length and outlets of the connecting pipes, water
discharge piping and the electrical wiring.
c. To keep the ceiling level and prevent vibrations, reinforce the strength of the ceiling when necessary.
2. Install the hooks in four corners based on the layout for the hooks outlined in the installation board.
a. Drill four holes with a diameter of 12 mm and a depth of 50–55 mm
in the ceiling. Then, insert and fix the expansion hook anchors.
b. During the installation of the hooks, make sure that the concave
portion of the hanger corresponds to that of the expansion hook
anchors. Determine the appropriate hook length for installation based
on the ceiling's height. Remove any excess.
c. Use M10 or W3/8 bolts for the screws of the mounting hooks.
d. Take approximately 1/2 of the screw length for the installed hooks
as the excess length L, as shown in Figure 5.
3. Use the hex nuts on the four mounting hooks to evenly adjust and make sure that the unit is level.
a. If the water discharge pipe is slanted, it may cause the water level
switch to malfunction, and water may leak.
b. Adjust the position of the unit, and make sure that the gap with the
ceiling is evenly spaced on all four sides of the unit, and the base of
the unit is 10–12 mm into the base of the ceiling (see Figure 5).
c. Once the position and level of the unit is adjusted, use the nuts on
◼
the mounting hooks to secure the air conditioner (see Figure 6).
New room and ceiling
1. Install the unit according to the above description. Pre-bury the hooks in the new ceiling, and make sure
that they are strong enough to bear the weight of the IDU, and that the unit will not become loose when the
concrete shrinks.
2. After lifting the unit, use M6×12 screws (accessory) to secure the installation board on the main body of the
air conditioner to pre-determine the size and position of the opening in the ceiling (see Figure 1).
