3. Make sure the two O-rings (3) have been placed
into the circular recesses located in the back of
the new terminal plate (4). Place the terminal
plate over the gasket (2) and fasten it securely
to the wall box with the five screws (5) provided.
The new plate is slightly longer than the old. Do
not cut the insulation; it will compress when the
plate is fastened.
4. The wall plate provided with the thermostat is
not used in this installation.
5. Carefully plug the thermostat into the terminal
plate (4). Wet or moisten the thermostat supply
and return ports to faciliate plugging the
thermostat into the O-rings located in the
terminal plate. This will lubricate the O-rings and
allow the thermostat ports to slip through them
more easily.
6. Insert two screws (6) through the thermostat.
Place two spacers (13) over the ends of the
screws (6). Seat the spacers into the recesses
located in the base of the thermostat. Secure the
thermostat to the wall box. When tightening the
screws, make sure the lock washers are not fully
compressed.
CAUTION:
Over-tightening the screws can cause a
shift in the calibration.
7. Set the thermostat to the desired setting.

8. Remove the screw and nut holding the aspirator
plate (9) to the back of the new cover (11). Insert
the aspirator nozzle (8) through the aspirator
plate and reattach it. Tighten until finger tight.
Align holes on the aspirator plate (9) and cover
(11) and fasten securely.
9. If the distance from the back of the wall box
(inside) to the mounting surface exceeds
1-9/16 inch (14 mm), the cover mounting screws
(12) will be too short. Use two 6-32 hex 1/2”
spacer posts (Grainger 6NZWS, Keystone
No. 1952) to correct this problem.
10. Connect the tubing on the terminal plate to the
nozzle fitting (8). A wire coil, which will help
prevent kinking, is provided inside the tubing.
Slide the tubing retainer (7) over the fitting to
secure the connection.
11. If there is a sealing gasket on the surface
around the wall box, remove and discard it.
Make sure the surface is clean. Three new seal
gaskets (10) are already attached to the back of
the new cover.
12. Position the cover (11) over the wall box. Be
sure the tubing does not press against the
thermostat bimetal. Tighten the two socket head
cover screws (12) with a 5/64-inch (2 mm) hex
Allen wrench until the seal gaskets are
compressed and the cover is tight against the
mounting surface.
CAUTION:
There must be a tight seal between the
cover and the wall box to have proper air
flow over the bimetal sensor.
