Thermometer Adjustment

The thermometer was accurately calibrated at

the factory and should only need adjustment if it
has been dropped or mishandled.

If the setpoint 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 a

thermometer of known accuracy.

Allow at least five minutes for cover thermom-

eter to sense area temperature; then compare
the readings. Be careful not to touch the ther-
mometer or breathe on it.

If the readings are the same, replace the

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.
