Mounting The Housing; Power Unit Installation - NuTone QuieTTest QT200 Installation Instructions Manual

MOUNTING THE HOUSING

NOTE: These ventilators are designed for installation between
16" O.C. ceiling joists with no framing necessary. If the
building structure has 24" O.C. joists construction, framing
will be required.
1. Position housing between ceiling joists and adjust height to
finished ceiling. Loosen two hex nuts for each mounting bracket
from inside the housing and make the adjustment. Tighten the
four hex nuts.
NOTE: There are four additional mounting slots in the
housing for mounting or relocating the mounting brackets.
2. Refer to Figure 4. Screw housing to joists using holes
in mounting brackets and four screws (included).
3. Install standard 3¼" x 10" ductwork from damper section
to outside wall or through roof and mount appropriate wall or
roof cap (not included). Refer to the instructions provided with
the caps.
IMPORTANT: Ensure there are no obstructions at the
discharge of the ventilator. Ensure insulation does not get
into the ductwork or into the blower.
WIRING
NOTE: All wiring connections must comply with local codes,
ordinances and the National Electrical Code and the ventilator
must be properly grounded. Disconnect power at circuit
breaker before making wire connections.
1. Refer to Figure 5. Loosen screws and remove junction box.
2. Run 120 VAC supply wiring with ground through switch box to
knockout in ventilator housing and secure with box connector.
3. Refer to Figure 6. Connect supply wires to ventilator wires:
BLACK to BLACK, WHITE to WHITE. Connect ground wire to
GREEN ground lead.
4. Reinstall junction box and tighten screws.
5. Connect supply wire to switch.
NOTE: Switch must be purchased separately. Refer to
NuTone's catalog.

POWER UNIT INSTALLATION

1. Refer to Figure 7. The power unit mounts with two hanger rods
to the mounting brackets. Start threading wing nuts (included)
onto hanger rods. Insert the hanger rods through the holes in
the mounting bracket hooking them from the inside to the
outside.
2. Position the power unit so that its discharge opening is in line
with the installed ductwork. Hold the power unit in position
between the mounting brackets and swing the hanger rods into
the slots on the power unit and securely tighten the wing nuts.
3. Plug the three wire connectors from the junction box into the
wire receptacle connector from the power unit making sure the
plug is properly aligned.
