The thermometer has been accurately calibrated at the factory and should only need adjust-
ment if it has been dropped or mishandled.
If the set point lever and the thermometer reading do not agree, follow the procedure below.
Remove thermostat cover and open the flip-up cover.
Set the thermostat cover on a table near thermometer of known accuracy.
Allow at least five minutes for cover ther-
mometer to sense area temperature, then
compare the readings. Be careful not to touch
thermometer or breathe on it.
If the readings are the same, replace cover
and put the system into operation.
If the readings are different, insert a small
screwdriver in the thermometer slot, shown
in Fig. 7, and turn it until both thermometers
read the same.
Replace thermostat cover and put the
system into operation.
