2. Pull the feeler bulb from the well which is usually located on the coil or header and pull the lead
wires off the control terminals.
If the temperature control is within the first year warranty and is to be returned for credit, be sure to
coil the tubing neatly and do not kink it or damage the control in any way. No credit can be issued for
any parts that arrive in a damaged condition.
3. Replace the control with an exact factory replacement or one equal to the original specifications. Be
sure the feeler bulb is in the proper well and tight. Do not allow the tubing connecting the feeler bulb
to the body of the control to touch the coil U bends.
Time clocks
In the cabinets which have bottom-mounted condensing units, the time clock will be located along the
side of the unit. It will be readily visible when the motor cover is removed. The timer is set at the factory
for two defrost periods with a fail safe of 40 minutes for both single and multiple door cabinets. (For SAV
models the timer is set at the factory for four (4) defrost periods of 30 minutes.) Tests have shown that the
factory setting is satisfactory for most applications. However, changes can be made after a sufficient trial
period if necessary.
The fail safe is controlled by the small copper pointer on the inner dial. To reset the timer, grasp the
knurled knob and turn it counterclockwise until the pointer is at the correct time. As soon as the power is
turned on, if the temperature control is in the “on” position, the time clock and condensing unit will start.
