• Clean the basin strainer and re-install.
• Cover the fan discharge to keep out dirt and debris.
• Lubricate the fan shaft bearings, motor base, and motor base adjusting screw.
• Apply RUST VETO
®
to steel shafts.
• Inspect the protective finish on the unit. Clean and refinish as required. Refer to
“Corrosion Protection” on
page 22
for more details.
• Lockout the fan motor starting device in the “OFF” position to ensure personal safety
in case of future inspection or service.
Prolonged Outdoor Storage
Storage Preparation
• Conduct the “Extended Shutdown” procedure on
page 6
if the unit is installed.
• Ensure the cold water basin is fully drained and the drain is open.
• For storage prior to installation, all components and accessories, which sometimes
ship inside the tower and are not a permanent fixture in the basin, should be removed
and stored indoors.
• Remove the drain plug from the optional EASY CONNECT
®
Piping Arrangement. The
drain should remain open throughout prolonged storage period. Retain the drain plug
for future installation
• Remove and store fan belts
(if supplied) at room temperature. Tag belts appropriately
for future identification.
• Apply a weather-resistant lubricant or heavy grease such as Anti-Seize (BAC Part #
160069) to all exposed threaded or flanged connections and adjustable motor base
threaded rod.
• Insert desiccant bags into the control panel (if supplied) to absorb moisture. Seal the
control panel for storage.
• Spray coat electrical component housings (if supplied) with a suitable protective
coating, such as Cosmoline
®
Weathershed, and individually cover them with plastic
taking care to leave openings for free air circulation.
• Inspect the protective finish on the unit. Clean and refinish as required. Refer to
“Corrosion Protection” on
page 22
for more details.
Motor Recommendations
BAC standard motors are designed for storage at ambient temperatures of -20ºF to 104ºF
(-28.9ºC to 40ºC). Prolonged periods of exposure above or below these specified conditions
could degrade components of the motor and cause malfunction or premature failure.
• Motors should be removed and stored inside whenever possible. When indoor storage
is not possible the motors must be covered with a tarpaulin. Do not use plastic or
plastic film. This cover should extend below the motor and be secured; however, it
should not tightly wrap the motor. This will allow the captive air space to breathe,
minimizing formation of condensation.
• Care must also be taken to protect the motor from flooding or from harmful chemical
vapors.

ATTENTION:
Covering the unit with
a clear plastic tarpaulin during
storage can trap heat inside the
unit and cause damage to the
PVC components. If units must be
covered during storage, an opaque,
reflective tarp should be used.
DANGER:
Do not perform any
service on or near the fans, motors
and drives, or inside the unit
without first ensuring that the
fans and pumps are disconnected,
locked out and tagged out.
