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
Specification Table.)
CAUTION:
Never plug in cooler until installation is
complete and unit has been tested for rigidity.

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 2973 CFM, model 4000 SM requires 6 square
feet (856 square inches) of opening (2973/1000 * 2 = 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 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 dis-
charge 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.

WATER CONNECTION
•
Install overflow assembly.
Remove nut and place nipple
through the hole in the pan, with the rubber washer between
the pan and the head of the drain nipple (Fig. 5). Screw on
nut and draw up tight against bot-
tom of pan. Insert overflow pipe in
nipple to retain water. Overflow
pipe may be removed to drain pan
when necessary. A garden hose
may be screwed on the drain
nipple to drain water away from
your unit.
