Prolonged Outdoor Storage
TrilliumSeries™ Adiabatic Products are shipped wrapped. If the unit is going to remain in
outdoor storage in excess of three months prior to installation, remove the strech-wrap and
tarp and follow the storage recommendations below.
Storage Preparation
• Ensure the sump is fully drained. Remove any leaves or debris that may have
accumulated in the sump and gutters.
• For extended shutdown periods after start-up, coils should be charged with nitrogen
at 15 psig in the field and capped by adding a threaded connection or a welded cap.
Upon start-up, the coil connections will require cutting.
• Insert desiccant bags into the EcoFlex™ Control panel to absorb moisture. Seal the
control panel for storage.
• Inspect the protective finish on the unit. Clean as required.
Motor Recommendations
TrilliumSeries™ Adiabatic Product motors are designed for storage at ambient
temperatures of -40ºF to 176ºF (-40ºC to 80ºC). Prolonged periods of exposure above
or below these specified conditions could degrade components of the motor and cause
malfunction or premature failure.
• 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
damage.
• Keep stored motor(s) dry and protected from weather.
• Rotate the fan once per month.
Preparation After Prolonged Storage
Keep in mind that start-up procedures after long periods of storage are just as important as
pre-shutdown procedures. Follow the instructions in the rest of this manual after prolonged
storage. Be especially thorough for cleaning and inspection prior to start-up. Also, check
the battery of the EcoFlex™ Control Panel.
NOTICE: BAC units are typically
installed immediately after
shipment and many operate year
round. However, if the unit is to
be stored for a prolonged period
of time either before or after
installation, certain precautions
should be observed.
