Resetting the Thermal Overloads
Model 505.20 - 505.30 SilentFlo™ HPU Operation 45
A tripped thermal overload or a blown fuse indicates a potential short circuit, too
much heat in the electrical box, or a component failure (mechanical or electrical).
To reset the thermal overload switches or replace the fuses:
1. Turn the main disconnect switch counterclockwise to remove power from
the electrical control box.
2. Loosen the two bolts securing the door of the electrical enclosure and open
the door.
3. Locate the thermal overload switch. Press the Reset button to clear the
switch. If thermal overload switch trips again, wait until it cools.
