3-6. How to Install the Ceiling Panel
3-6-1. Before Installing the Ceiling Panel
Checking the unit position
(1) Check that the ceiling hole is within this range:
33-55/64 × 33-55/64 to 35-53/64 × 35-53/64 in.
(2) Use the full-scale installation diagram (from the
packaging) that was supplied with the unit to
determine the positioning of the unit on the ceiling
surface. If the positions of the ceiling surface and
unit do not match, air leakage, water leakage, flap
operation failure, or other problems may result.
CAUTION
● Never place the panel face-down. Either hang
it vertically or place it on top of a projecting
object. Placing it face-down will damage the
surface.
● Do not touch the flap or apply force to it.
(This may cause flap malfunction.)
must be within the range of 15/32 – 43/64 in.
If not within this range, malfunction or other trouble may result.
