Prolonged Outdoor Storage
Storage Preparation
• Conduct the “Extended Shutdown” procedure on page 5 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 unit and are not a permanent xture
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, keeping
matched belts together. Tag belts appropriately for future identication.
Precautions for RCF Closed Circuit Cooling Towers
- RCF Storage Prior to Installation - The unit’s coil connections
should remain capped for the duration of storage.
- RCF Installed and Piped but not Filled - This unit does not
require additional precautions.
- RCF Unit Installed and Operated - This unit should remain lled.
If the unit is stored in a freezing climate, the coil must be
protected from freezing. For protection against coil freeze-up,
use of an inhibited glycol solution is recommended. If protecting
the coils with glycol is not possible, the galvanized steel coils
should be drained completely and capped once as much water
and moisture is removed from the coil as possible.
Precautions for RCC Evaporative Condensers
- RCC Storage Prior to Installation - The coils are charged with
nitrogen at 100kPa at the factory.
- RCC Extended Shutdown Periods after Start-Up - The coils
should be charged with nitrogen at 100kPa in the eld and
capped by adding a threaded connection or a welded cap. Upon
start-up, the coil connections will require cutting and bevelling.
• Apply a weather-resistant lubricant or heavy grease such as Anti-Seize
(BAC Part # 160069) to all exposed threaded or anged 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 nish on the unit. Clean and renish as required.
Refer to “Corrosion Protection” on page 24 for more details.
