also be taken to prevent insects from gaining access to the interior of the motor.
• If not stored indoors in a controlled environment, some form of heating must be
utilized to prevent condensation from accumulating in the motor. This heating should
maintain the winding temperature at a minimum of 9ºF (5ºC) above the ambient
temperature of the surrounding environment, keeping it from dropping below the dew
point where condensation could form inside the motor. If space heaters are supplied,
they should be energized. Request the required voltage and transformer capacity from
your local BAC Representative. A third option is to use an auxiliary heat source and
keep the winding warm by either convection or blowing warm air into the motor.
• Lubricate the fan shaft bearings at shutdown. Rotate the motor shaft monthly to
redistribute bearing grease.
• Remove and store fan belts at room temperature, keeping matched belts together. Tag
belts appropriately for future identification. Failure to remove the belts from the unit
for storage can result in severe degradation of the belt life.
• Coat steel sheaves with RUST VETO®, especially where the belt rides, to protect the
sheaves from corrosion. RUST VETO® can be removed with mineral spirits and must
be removed from the grooves of the sheaves before start-up.
Controls (If Ordered)
• Insert desiccant bags into the control panel to absorb moisture. Seal the control panel
for storage.
• Spray coat electrical component housings with a suitable protective coating such as
Cosmoline® Weathershed, and individually cover them with plastic, taking care to
leave openings for free air circulation.
Miscellaneous
• Apply a weather-resistant lubricant or heavy grease such as Anti-Seize (BAC part #
160069) to all exposed threaded or flanged connections as well as the sliding motor
base and motor base adjusting screws if applicable.
• For storage prior to installation, all components and accessories which are not
permanent fixtures in the basin but are shipped inside the unit, should be removed
and stored indoors to protect the components from exposure during storage.
• Verify combined inlet shield retainers are compressed to engage the combined inlet
shields (CIS). This will prevent the CIS from separating from the unit during high
winds.
• Inspect the protective finish on the unit. Clean and refinish as required. Refer to
“Corrosion Protection” on
page 18

will cause severe personal injury
or death to persons who come in
contact. Do not perform any service,
maintenance or inspection on or
near the fans, motors, and drives,
or inside the unit without first
ensuring that the fan and pump
motors are disconnected, locked
out, and tagged out.
