Winterizing Your Swamp Cooler

• There are things that you should do to winterize
  your Swamp Cooler. Winterizing your swamp cooler
  will save you extra money for cooler maintenance.
  Winterizing will also help make your swamp cooler
  last several years longer. Below are some simple
  steps that you should do to winterize your swamp
  cooler during fall season

3

• Be sure to turn off the power supply before
  doing anything on your swamp cooler. When
  winterizing your cooler, you should power off
  your unit. It is recommended to disconnect the
  unit or any appliance from the power source
  before testing and working on it.

• Switch off the regulator that supplies water to
  your cooler. You must also drain the water line
  to avoid freezing throughout the winter.
  Unplugging the water line at the swamp cooler and
  the supply valve can do draining water. Be sure
  that the water line is in sloping position to
  drain the water by itself. To drive the water out
  of the water line, you must go to the uppermost
  end and blow past the line.

5

• All swamp cooler are designed with a drain in the
  water pan. The water pan must be emptied before
  winter and the drain must left open to let
  rainwater to seepage in the duration of the
  winter. After draining the pan, you will find
  mineral sediment and dirt in the base of the
  water pan. The pan must always be washed and
  cleaned out.

6

• The water in your swamp cooler has been
  evaporating during summer time while the minerals
  and sediments continue to develop in the pan of
  your cooler. You can use a vacuum to get rid of
  the minerals and the dirt. Hose out the cooler
  pan with water while the drain remains open. It
  will completely remove the sediments and minerals
  out of the water pan and will help prevent the
  metal pan from rusting throughout the winter.

7

• It is recommended to change the cooler pads of
  your unit when winterizing. You should change the
  pads in the fall and not during spring. Always
  remember that old cooler pads have had dirt and
  minerals developing in them all throughout the
  summer. Louver panels can sometimes speed up the
  rusting of the pads because they are pressed
  against the metal louvers. To avoid rusting
  throughout the winter, you should install fresh
  new pads in the fall.

8

• Last but not the least is the cooler cover
  installation. Installing a cooler cover will stop
  the rainwater from rusting your unit. More
  importantly, the cooler cover installation will
  prevent the outside air from getting into the
  building or home being brought by the swamp
  cooler.

9

• Many home coolers include a damper, which can be
  opened and closed. This damper can stop the air
  from getting into the ducts and entering the
  building. A cooler cover is required if you dont
  have a damper. You will also need a cover if the
  damper cannot effectively stop outside air from
  leaking in.
