Evaporative coolers are only for dry climate
conditions or deserts. They cannot cool
as much as central air or air conditioners which have compressors and refrigerant. The mechanics are simple requiring a water
float valve, pump, spider (water distribution), aspen wood pads, blower, belt,
motor, and switch. The unit must have a water
supply to replenish the system due to evaporation. Your system may have a float
valve which you need to adjust to shut off when the water pan is full. Floats
can be adjusted by loosening the pivot screw and moving the float up and down
to adjust the turn off level or by turning the float to extend or retract the
length changing the water shutoff position. You do not want the water to be so
high it flows out the over flow tube but the water should cover pump base. Plug
in the unit and turn the switch to pump if you have that option on your
unit. This will engage the pump to force water from the pan up to the spider to
saturate the pads with water. After a few minutes turn the switch from pump to
low or high cool. New aspen pads will have an distinct smell which will go away
after a few days of usage. If you do not have a pump setting turn the switch to
low or high cool which will blow warm air at first then start to cool down. You
may also have a fan setting which will blow outside air without any additional
cooling if the outside air is humid. Occasional maintenance is to make sure the
pump is pumping water and the filter basket is clean and all the spiders are
working with water flowing freely. You can use a flexible wire to force it in a
spider tube to clean it if it is clogged. You may want to change the water
after a month to keep the system cleaner from slime and calcium. At the end of
the season disconnect the water supply and drain the water pan blowing out the
water line if the winter is below freezing. Replace the pads if they have
calcium build up or dry. Flush the water pan out and clean the Add some oil to the pillow blocks which are
the bearings at each end for the blower. Check the belt and pulley for
excessive wear. Cover the unit with canvas to prevent cold air from coming in
during the winter. Next summer season all you have to do is uncover the unit
and hook up the water supply.
