MOTOR DRAIN PLUGS
CAUTION: The fan must be mounted with a condensation drain fitting located at the lowest point of the motor. Damage
resulting from failure to follow these instructions will void the warranty.
Naturally occurring condensation from thermal activity will accumulate within the motor and must be allowed to drain.
Your Schaefer washdown duty fan is assembled with the drain fitting(s) installed in the motor opposite of the yoke mount bracket.
Recommended fan installation has the motor oriented with the yoke bracket up. You must relocate the drain fitting(s) to the lowest
point of the motor if your installation is different than described here.
Condensation drain fittings are installed where indicated below. Quantity, type, and location vary based on motor design.
