CAUTION
When using toggle wing nuts
●
The 2 toggle wing nuts are used as a temporary
measure when suspending the unit. Observe the
tolerances shown at right. The unit cannot be
installed correctly if there is more than 5 mm
clearance between the end of the suspension bolt
and the bottom of the toggle wing nut, as noted in
the illustration. (Fig. 3-69)
●
After suspending the unit to the correct level, the
toggle wing nuts must be removed and permanently
replaced with the supplied special washers and
hexagonal nuts.
b)
Lift the indoor unit and position it so that the
toggle wing nuts (mounted diagonally as
shown in Fig. 3-70) slip through the suspen-
sion holes of the unit. The wings will pop
out and the unit is temporarily secured.
c)
Check that no wiring is caught or crushed
between the toggle wing nuts and the
indoor unit. Then attach the 2 sets of
special washers and hexagonal nuts to the
remaining 2 suspension bolts. Thread on
the hexagonal nuts enough so that the
weight of the unit is removed from the 2
temporary toggle wing nuts.
d)
Remove and replace the 2 toggle wing nuts
with the remaining 2 sets of special wash-
ers and hex nuts. Use only 1 hexagonal nut
for each bolt until final adjustment (next
step).
e)
Adjust all 4 sets of washers and hexagonal
nuts so that the indoor unit is evenly
suspended.
f )
Finish the suspension by adding 1 addi-
tional hexagonal nut to each suspension
bolt. Tighten these nuts tightly to prevent
the upper nuts from loosening. (Fig. 3-70)
The ceiling surface is not always level. So that the
installation is correct, leave a clearance of 1 cm
between the ceiling panel and the ceiling surface and
fill the gap with an appropriate insulation or filler
material.
(7)
If the tubing and wiring are to go towards the rear
of the unit, make holes in the wall.
(Fig. 3-71)
(8)
Measure the thickness of the wall from the inside
to the outside and cut the PVC pipe at a slight
angle to fit. Insert the PVC pipe in the wall.
(Fig. 3-72)
NOTE
The hole should be made at a slight downward slant to
the outside.
