Prolonged Outdoor Storage
Storage Preparation
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 with vents should be used.
•
Conduct the Extended Shutdown procedure on Page 15 if the unit is installed.
•
Ensure the basin is fully drained and the drain is open.
•
For storage prior to installation, all components and accessories, which sometimes ship inside the unit and are not a
permanent fixture in the basin, should be removed and stored indoors.
•
Remove the bottom drain plug to the spray pump(s). Put the plug(s) in a marked plastic bag and attach to the spray
pump(s) for future use.
•
Remove and store fan belts (if supplied) at room temperature. Tag belts appropriately for future identification.
•
During storage, the coils should be charged with inert gas and capped. Note that coils with steel connections are charged
with 15 psig nitrogen at the factory prior to shipment.
•
If the condenser is removed from the system, charge the coil with 15 psig of inert gas and cap the connections to reduce
the risk of internal corrosion.
•
Apply a weather-resistant lubricant or heavy grease such as Anti-Seize (BAC Part # 160069) to all exposed threaded or
flanged connections and the 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 section 5. Corrosion Protection on Page
29 for more details.
