Storage & Extended
Shutdown
2
Prolonged Outdoor Storage
• Conduct the “Extended Shutdown” procedure on
page 19
if the unit is installed.
• For storage prior to installation, all components and accessories that ship loose should
be removed and stored indoors.
• Ensure the spray water basin is fully drained and the drain is open.
• If the manifold is constructed of carbon steel, then the hCore
®
Heat Transfer
Technology should be capped and charged with nitrogen at 15 psig in the field and
capped.
• Insert desiccant bags into the control panel(s) to absorb moisture. Seal the control
panel for storage.
• Inspect the protective finish on the unit. Clean and refinish as required. Refer to
“Corrosion Protection” on
page 30
for more details.
Motor Recommendation
BAC standard motors are designed for storage at ambient temperatures of -13ºF 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.
• EC Fan System should be removed
and stored inside whenever possible. When indoor
storage is not possible the motor must be covered with a loose fitting tarpaulin. Do
not use plastic/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.
• The storage area should be free from ambient vibration. Excessive vibration can cause
bearing damage. Motors that must be stored in areas with high ambient vibration,
such as from heavy construction equipment or other sources, must have the fan
secured to prevent any movement.
• Precautions should be taken to prevent rodents, snakes, birds, or other small animals
from nesting inside the unit. In areas where they are prevalent, precautions must also
be taken to prevent insects from gaining access to the interior of the unit.
NOTICE:
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:
Rotating equipment
will cause severe personal injury
or death to persons who come in
contact. Do not perform any service
on or near the fans or motors
or inside the unit without first
ensuring that the fans and pump
motors are disconnected, locked
out, and tagged out.
