Using the four bolts provided, secure the ceiling assembly frame to the roof top unit. The four mounting bolts are
to be applied up through the bottom of the ceiling assembly frame and into the bottom of the roof top unit.
Mounting bolts should be tightened evenly. A rotating tightening procedure is essential for proper gasket
compression. The bolt tightening procedure is complete when the gasket under the roof top unit has been
evenly compressed to 60%.
* CAUTION (for low profile)
If your ceiling depth is thinner than 2", you should use shorter bolts(5" long) at the front side.(2ea)

Attached to the electrical circuitry of the ceiling
assembly frame is a low temperature sensor. The
low temperature sensor exits from the ceiling as-
sembly frame electrical box. The freeze circuit ther-
mistor probe (See Figure 8) installs by inserting it
straight in the center area of evaporator coil, then
raising the back of the probe and continuing at a
45°angle until the probe is fully inserted.
To gain access to the fins of the evaporator coil,
reach up through the return air opening in the
bottom of the roof top unit. See Figure 8.
The sharp edges of evaporator coil may cause personal damage. Put on gloves when installing the thermistor
probe. See Figure 8.
