Electrical Installation
WARNING: Disconnect all electrical service that will be used
for this unit before you begin the installation.
Cooler Installation
CAUTION: Make sure that the mounting surface is strong
enough to support the operating weight of the cooler when in use.
(For operating weight, see Specifi cation Table.)
CAUTION: Never plug in cooler until installation is complete
and unit has been tested for rigidity.
CAUTION: Do not screw or drill within 5 inches of the bottom
of the wet module. You could puncture the reservoir.
CAUTION: If the unit is supported with legs at each corner,
the middle of the unit where the two sec-
tions join must be supported as well.
NOTE: You can separate the wet module
from the blower module by removing the 4
bolts from the wet module side (Fig. 1) On
some models you will also need to remove
2 bolts which secure the bottom pan of each
section together.
Motor Installation
• Install motor cord. For typical 120V installation, connect motor
cord to motor using the following color code: Black - Hi, Red - Low,
White - Com., Green - Ground.
• Mount motor. Install blower motor in the motor mount yokes,
adjusting the yoke if necessary. Fasten with the provided mounting
clips (see Fig. 2). NOTE: Adjustable yoke will have to be reversed
for 1 H.P. motors.
• Install pulley. Install the adjustable motor pulley so that it aligns
with the blower drive pulley (see Fig. 3) and tighten set screw.

Open Windows To Exhaust Air
An often misunderstood concept of evaporative cooling is the amount
of air that should be exhausted. How much should you open your
windows? The fact is that most people do not open their windows
enough. The following two methods will help you determine the
amount to open your windows.
First Method
You should allow an opening of at least 2 square feet (288 square
inches) for each 1000 CFM rating of your unit. Example: At 3320
CFM, model ADA 51 (1/2 hp) requires 6.6 square feet (950 square
inches) of opening (3320/1000 * 2 = 6.6). Multiply the number of
windows by window width in inches and divide this into the number
of square inches required for your size unit. This will give you the
height to open windows. In this example, four 36 inch wide windows
should be opened 6.6 inches each.
Champion Air Balancing Method
1. Take a piece of tissue paper and cut it lengthwise into 3 equal
strips.
2. Turn your cooler on high cool.
3. Open one window at least six inches wide in each room that you
want to cool.
4. Take the piece of tissue paper and put it up against the screen of
the open window furthest from the cooler discharge opening. Let
go of it. It will do one of three things.
IF It falls down.
THEN CLOSE all of the windows one inch and try step 4 again.
IF It plasters itself to the screen.
THEN OPEN all of the windows one inch and try step 4 again.
IF It stays on the screen lightly.
THEN PERFECT. You are done. Enjoy your cooler.
NOTES:
• When switching to low cool, you must rebalance your home. Repeat
step 4.
• Once you balance your home you can cool some areas more than
others by opening those windows more and closing the others by
the same amount. Repeat step 4 to make sure your home is still air
balanced.

Operation
To eliminate the delivery of hot air when starting the cooler, start the
pump only for the fi rst few minutes, then turn on the blower motor.
These coolers may be used without water for ventilation purposes.
When outside air is cool (for example, at night) or when humidity is
high the water pump can be turned off.
A cooler can also be installed with a thermostat and attic exhaust
dampers to provide completely automatic operation.
• Remove junction box. The electrical junction box is located in
the upper inside of the left center post. Remove the two screws
and pull box out from panel for access to plug wiring (Fig. 4).
