2.10 Locate the corner on the shutter where the outer flange
meets the vertical tie bar. Measure ½" to the left of this

drill bit (see figure 5).
2.11 Hook one end of the return spring into the hole you just
drilled and hook the other end around the hole located
by the second louvre from the top (see figure 6).
2.12 Insert an S-hook into the first available hole below the
return spring on the tie bar (see figure 6), and attach
another S-hook to the motor arm (see figure 7). Trim the
excess chain.
Note: Connect the chain between these two S-hooks
so that there is just a slight amount of slack.
2.13 Plug the power cord into the grounded outlet on the
thermostat cord.
STEP 3: INSTALLING THE THERMOSTAT
3.1 Mount the thermostat onto your tunnel wall using
#14 X 1" Tek screws or #12 X 1½" Woodmate screws.
Note:
The thermostat should be placed at a convenient
height for operation.
3.2 Plug the power cord into the grounded outlet that meets
national, regional, and local codes.
Note: Be sure to create a drip loop with the electrical
cord, to prevent water from entering the thermostat
housing.
