Preparing for Shutdown

August 2, 2018

 

 

While the summer heat is sticking around for now, before long, it will be time to close down your evaporative cooler until next season.  While the steps to shut down your cooler are less intensive than spring start-up requirements, they’re still important.  Here’s a refresher so you can prepare for what’s to come!

 

Before beginning any cooler maintenance, it is important to remember to turn off all electrical power to the cooler and to unplug it.  Also, disconnect the motor.  This will lessen the chance of injury while servicing your cooler.

 

First, shut off the water, unplug the pump, and disconnect the water line from your cooler.  Drain the line and blow out the extra water.  If possible, store the line for winter.  Otherwise, leave the water line disconnected from the source to ensure that no water leaks into the line.

 

Once the water line is prepared, remove the belt and store it in a cool, dry place.  Connect a garden hose to the overflow assembly or drain plug.  Drain the water from the base of the cooler by removing the overflow pipe.  Point the other end of the hose away from the lawn and other landscaped areas because the water can contain mineral buildup that is rough on soil and plants.  Sponging out the excess water may be necessary.  Be thorough to prevent rust. 

 

Sweep any remaining sediment toward the drain hole.  Scrub the interior and exterior of the louvers/panels and water tray.  Be cautious not to damage the paint.  Once this is complete, rinse the debris away from the cooler.

 

Examine the cooler for spots of bare metal.  Pay close attention to the louvers/panels and the bottom pan.  Should rust be found, scrub it with steel wool to remove it.  Let it dry, then spray the bare metal with paint primer.  Once dry, repaint the areas with outdoor rust preventative.

 

The next step in cooler winterization is optional, as it can either be performed at shutdown or spring start-up.  Whenever you decide to do it, make sure that it is done, as it is an imperative step in cooler maintenance: clean or replace the cooler pads or media.  Aspen pads should be discarded at the end of each cooler season, but rigid media lasts much longer.  Clean it to remove any mineral deposits.  Be careful not to damage it, and never use a pressure washer.  Allow rigid media to dry completely before reinstalling in your evaporative cooler.

 

Finally, use a heavy-grade canvas cover to keep dust, dirt, and cold air out of the cooler during the winter.  The cover also provides insulation and protects against heat from escaping.  Never use a plastic cover for a cooler because the condensation could cause rust or early deterioration.  Lastly, close off the cooler vents, and you’re all done!
