HOW TO USE YOUR COOLER
HOW YOUR COOLER WORKS
Your cooler evaporates water to cool air.
Evaporative air cooling is the same natural
cooling that happens when a breezesprings 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 cooling
Relative humidity affects the cooling capacity
of any cooler. See chart to determine the
maximum amount of cooling possible at your
outside temperature and outside humidity
(Figure 15)
COOLING 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
