4.5. Confirming the Position of Main Unit
and Tightening the Suspension Bolts
Using the gauge attached to the grilles, ensure that the bottom of the
main unit is properly aligned against the opening on ceiling. Be sure to
confirm this, otherwise the dripping of condensation due to leakage of
wind and etc occur.
Confirm that the main unit is horizontally levelled, using a level or a
vinyl tube filled with water.
After ascertaining the position of main unit, securely tighten the nuts of
suspension bolts to fasten the main unit.
Installation template attached to the crating materials can be used as
a protection sheet to prevent the dust from entering into the main unit
when the grilles are to be left without fitting to the unit for a while or in
case that the ceiling materials are to be lined after finishing the instal-
lation of the unit.
As for the details of fitting, refer to the instructions given on the Instal-

A Make the embedding deep
B M10 (3/8") bolt
C Fasten with bolt
D Make wide
2 Bolt pitch for side-by-side arrangement of units:
H 500 mm
I Min. 380 mm
E Installation base
F Max. 25
G Length of foundation bolts
J Min. 10 mm
K 330 mm
