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-
lation template.
A Main unit
B Ceiling panel
C Installation template (attached to the crating materials)
D 4-screw with the washers (Accessory)
Caution:
•
It is best to transport the unit in its original packaging to the in-
stallation site.
•
Since the centre of gravity of the unit is off-centre, caution is nec-
essary when lifting the unit using a rope, etc.
•
The outdoor unit should not be tilted by more than 45
porting. (Do not stock them sideways.)
1 Prepare the concrete foundation
Always anchor outdoor unit legs by means of bolts. (Procure anchor bolts
locally.)
Secure firmly to prevent overturning by earthquakes or gusts of wind.
Keep the length of foundation bolts up to 25 mm from the bottom side
installation base.
A Make the embedding deep
B M10 (3/8") bolt
C Fasten with bolt
D Make wide
