Replacement Door for 1F90 & 1F97
Comfort-Set II Digital Thermostats
Before installing the new door onto your digital thermo-
stat, you will need to attach one of the two operating
instruction labels to the new door.
1. Determine the type of thermostat you have. If the two
buttons on the far right of the thermostat look like
fig.1, you will use the label numbered 153-2324 (for
the 1F97).
If the two buttons on the far right of your thermostat
look like fig.2, you will use the label numbered 153-
2325 (for the 1F90).
2. Place the thermostat door on a table and position it so
that the recessed area is facing up, and the door is
positioned as shown in fig. 3.
3. Peel the backing off the label you will use. Working
from the upper edge, lay the label in place on the
door. Gently wipe the label down to remove any air
bubbles.
4. To install the door, insert the extruded dimples into
the recesses located on the lower right and left edges
of the thermostat (it may be necessary to bend the
door slightly to fit it into place).
