SQ-2
Electronic VAV Diffuser
Step 1 The units should be shipped assembled except for the backpan. The thermal T
3
SQ is shipped with
additional packaging to protect the actuator assembly. Remove all packaging from the components.
If the unit is not assembled, follow the steps below before proceeding (see Figure 1):
1. Insert the control disc guide into the control disc.
2. Screw the bottom of the actuator / control disc assembly into the mounting channel.
Place the back pan into ceiling grid. Connect duct work to back
pan. Insert the supply air temperature sensor into the supply
duct. If the unit has an optional inlet heater, the supply air
sensor must be positioned above the heater in the supply duct.
Installation is completed by lining up the hooks on the face
plaque assembly with the corresponding slot. Attach the ribbon
cable on actuator / control disc assembly through wiring conduit.
The hooks are inserted and the face plaque assembly is rotated
clockwise, and lowered so that each hook is firmly in place. (See
Figure 2)
Plug the ribbon cable on actuator / control disc assembly into
any ribbon cable connection on the wiring interface box on the
backpan.
