7. A temperature switch is provided to control oil sump
temperature. See Figure 2 for proposed wiring.
There are two separate circuits in the temperature
switch. The low circuit is to operate the electric fan.
It is recommended the fan motor be operated by
the temperature switch through a motor starter relay
(consult applicable local and national electrical codes).
The high circuit is provided to operate either a high
temperature alarm or main motor shutdown.

8. Connect power to the motor using an approved wiring
method. See Figure 1 for connection diagrams.
9. Before starting the fan, double check to ensure there
are no obstructions that could interfere with proper
fan operation and airflow. Verify proper fan rotation,
resulting in air flow directed at the adjacent face of the
gear drive.
10. Remove proper condensation plug. See Figure 3
below. Do not discard. Plug is to be used during
cleaning.
NOTES
:
AIR SUPPLY AND TEMPERATURE
— Sufficient air supply
over the motor must be assured in all circumstances.
Limits of operating ambient temperature are 14°F to 113°F
(–10°C to 45°C).
