Introduction
The following instructions apply to the installation of the electric
fan. The sump temperature switch is provided as a standard
feature.
The sump temperature switch features dual settings for two
independent single-pole, double-throw circuits. Only one
circuit is used to control the fan. The remaining circuit may be
used to control a warning light, an alarm, or a motor shutdown
switch if the temperature setting is exceeded. The sump
temperature switch wiring diagram is given in Figure 1.
Refer to Figure 2 for electric fan, temperature switch and bulb
well standard mounting locations. The bulb well houses the
sump temperature probe. These mounting locations are based
on drive mounting position.
Assembly Instructions
WARNING:
Consult applicable local and national safety
codes for proper guarding of rotating members.
Lock out power source and remove all external loads from
drive before servicing drive or accessories.
1. Drain oil from the drive.

ELECTRIC FAN PANEL REWORK —
The holes in the
electric fan panel must be enlarged to accommodate the
fasteners used to mount the electric fan to the shroud. Align
the fan panel to the shroud. Locate and drill four 0.4375”
(12 mm) diameter clearance holes in line with the pre-drilled
holes in the shroud.
3. Insert four 1.25” (32 mm) cap screws through the fan
mounting holes in the shroud with the threaded portion of
the cap screw away from the drive. Secure the cap screws to
the shroud with flat washer (2 washers for 4407) and nut,
see Figure 3.
4. Secure the sump temperature switch to the switch mounting
bracket. Attach the switch and mounting bracket to the fan
shroud, refer to Figure 2 for location.
5. Install the temperature probe bulb well in the designated
drain hole as shown in Figure 4. Refer to Figure 2 for bulb
well location.
CAUTION:
Sump temperature probe must be located below
oil level.
