Install New Thermostat
1. Feed tubes through large adapter plate hole
(see Fig. 4).
2. Match adapter plate holes to wall screw holes.
3. Mount adapter plate using screws retained from
old mounting plate removal. Do not over-tighten
screws.
NOTE: If any wall screw holes coincide with
noncoded adapter plate holes (see
Fig. 4), proceed as follows. (If not,
continue with Step 4.):
a. With adapter plate away from the wall,
ream out or strip threaded holes by
tightening screws retained when
removing the old mounting plate.
Tighten with enough force so that the
screws move freely.
b. Remove and retain screws. If wall
screw holes are larger than #6,
enlarge adapter plate holes to allow
enough clearance for screws.
c. After removing temporary plug, push
tubes onto thermostat backplate (main
tube has air blowing out and must be
connected to the M barb connection on
backplate rear).
d. To remove thermostat cover, slowly
drive screws clockwise until cover is
free. To remove thermostat from
backplate, spread retaining clips and
separate (see Fig. 5).
e. Align and attach backplate and adapter
plate to mounting screw holes using
screws retained from stripping adapter
plate threads.
f. Proceed to Step 7.
NOTE: When adapting to a Johnson thermostat,
if wall holes are out of alignment with
adapter plate holes, use any available
hole for an additional wall anchor.
