HOW TO USE YOUR COOLER
HOW YOUR COOLER WORKS
Your cooler evaporates water to cool air.
Evaporative air cooiing is the same natural
cooling that happerts when
a breeze springs up
after a summer shower. You feel cool because
the rain water evaporates and carries away
heat-
Your new cooler has a motor (1) driven blower
(2) which draws outside air through pads (3)
which are turned by drive motors (4) The pads
turn through water in trays (5) filled by the
water float valve (6) and water crossover pipe
(7) Air passes through the pads, is cooled by
water evaporation, and is sent into your home.
(Figure 14)
You may also run the cooler in “Vent" when
you want fresh air and no cooiing
Relative humidity affects the cooiing capacity
of any cooler See chart to determine the
maximum amount of cooiing possible at your
outside
temperature and outside humidity
(Figure 15)
COOLINO YOUR HOME
Your cooler and window or vents are the two
parts of your air cooling system. Outside air is
filtered and cooled, goes through your home,
and carries away heat and household odors
You control the air cooling flow to your rooms
by opening doors, windows, or vents. (Figure
16)
You must have window, door, or vent openings
to let air out when the cooler runs The total
opening areas you need ate shown below:
