NOTE:
If outdoors, apply Duct
Seal inside the pipe portion of the
back box to prevent moisture or
cold air inside the mount from en-
tering the unit and causing conden-
sation on the dome. Make sure no
moisture has condensed inside the
unit before installing the lower
dome. Duct Seal can be purchased
through local electrical supply
houses.

4.0 INSTALLATION FOR PENDANT MODELS

4.1 PENDANT-MOUNT INSTALLATION

1. Install the pendant dome mount. Refer to the instructions supplied with the
mount. If the mount is outdoors, make sure it is properly sealed to keep mois-
ture out.
2. Bring the wiring for the dome through the mount. Refer to Section 3.2, WIR-
ING.
3. Refer to Figure 9. Loosen the thumbscrew inside the back box and open the
hinged door.
4. Screw the back box into the mount and bring the wiring into the back box. If
outdoors, apply the provided pipe sealant to the threads on the back box.
5. Attach the wiring to the back box. Refer to Section 3.4, BACK BOX CONNEC-
TIONS.
6. Install the dome drive. Refer to Section 3.5, DOME DRIVE.
7. Remove the O-ring and O-ring lubricant from the parts bag. Apply lubricant to
the O-ring. Install the O-ring in the groove on the trim ring of the lower dome.
8. Refer to Figure 14. Hanging down from the back box is a short cable (the trim
ring leash). Hold up the lower dome near the back box so that the trim ring
leash touches the lower dome. Line up the two screw holes in the trim ring of
the lower dome with the two screw holes in the back box. Place a finger on the
edge of the trim ring where the leash touches the lower dome.
