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.

Amust be within the range of 15/32 – 43/64 in.

If not within this range, malfunction or other trouble may result.
