INSTALLATION
MOTOR PULLEY ADJUSTMENT
NOTE: ALL DUCT CONNECTED COOLERS MUST
BE ADJUSTED.
Long or small air ducts have excessive air resistance
which decreases air output and motor amperage. You may
compensate for this by adjusting the motor pulley. Use a
clamp type ampmeter to check the motor amperage.
1. Check amperage at the white lead in the wiring box.
2. If the amperage is less than the motor nameplate
amperage, loosen the pulley pitch adjustment screw,
turn in the pulley 1/2 turn, tighten the screw and
recheck the amperes. Repeat as necessary to bring
the amperage to the nameplate rating.
3. If the amperage is too high, turn out the pulley as
required.

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 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
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.
