HOW YOUR COOLER WORKS
Your cooler evaporates water to cool air. Evaporative
air cooling is the same natural cooling that happens
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.
If the output air is too cool you may switch this cooler
from “Maximum Cool” to “Minimum Cool” (when used
with ESSICK ECR-7 7-position wall switch). Then only
one pad will turn, reducing the cooling effect. You may
also run the cooler in “Vent” when you want fresh air and
no cooling.
COOLING YOUR HOME
Your cooler and windows 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.
You must have window, door, or vent openings to let
air out when the cooler runs. The total opening
areas you need are shown below:
