Thermometer adjustment

The thermometer was accurately calibrated

at the factory and should only need adjustment

if it was 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 the

thermometer of known accuracy.

Allow at least five minutes for the cover

thermometer to sense the area temperature,

then compare the readings. Be careful not to

touch the thermometer 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.

Replace thermostat cover and put the

system into operation.
