Installation procedure

CAUTION

Unit Leveling!

All unit panels and filters must be in place prior to unit start-up. Failure to have panels and filters in place may cause motor overload.

Note: The trim ring assembly cannot accomodate unlevel ceilings.

Note: On sizes 8, 10, & 12 center installa- tion position and use 2 or 3.5-inch bolts, whichever is best suited for installation. Also, install two safety chains assemblies on these sizes.

Note: Expansion collar is furnished with fan-coil with bottom return only. The collar is not necessary for Force Flo units.
