OPERATION

Set automatic thermostat to meet your requirements. The ther- mostat has an adjustable range from 60º to 120º and operates on a 15º differential. For example, factory setting is 100º. At this set- ting, as soon as temperature reaches 115º, thermostat will close and start ventilator. When temperature has been reduced to 100º, thermostat will open and ventilator will stop. Dial pointer may be set at temperature that is best for local conditions.

NOTE: Remember the 15º differential. If dial point is set on 120º, ventilator will start at 135º and operate until temperature has been reduced to 120º, a difference of 15º. (See Figure 8.)

WARNING: MOTORS ARE THERMALLY PROTECTED AND AUTOMATICALLY TEMPERATURE CON- TROLLED AND MAY START WITHOUT WARNING. THEREFORE, MAKE CERTAIN THAT POWER SOURCE IS DISCONNECTED BEFORE ANY ATTEMPT TO SER- VICE OR DISASSEMBLE ANY COMPONENTS! IF POWER DISCONNECT IS OUT-OF-SIGHT, LOCK IT IN THE OPEN POSITION AND TAG TO PREVENT APPLI- CATION OF POWER.

Lubricate motor every 6 months using SAE 20 non-detergent oil. Insert 2-3 drops of oil in the oiling hole on the back plate of the motor.
