Evaporative Cooling
Evaporative cooling is nature’s way of cooling. When air is moved over
a wet surface, water is evaporated and heat is absorbed. When stepping
out of swimming pool with the wind blowing, evaporative cooling makes
you feel cool, even though the air may be warm.
This unit works on the same principle. Air is drawn across wet lter pads
where the air is cooled by evaporation and then circulated throughout
the building. It is this combination of cooled air and the movement of
air over the skin which makes it feel cool.
Unlike refrigeration systems which recirculate the air, an evaporative
cooler continually brings in fresh air while exhausting old air. You are
completely replacing the air every 2 to 4 minutes by opening windows or
doors or a combination of both. The air is always fresh, not stale, laden
with smoke and odors as happens with refrigerated air conditioning.
Operation
To eliminate the delivery of hot air when starting the cooler, start the
pump only for the 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.

Electrical Installation
WARNING: Disconnect all electrical service that will be used
for this unit before you begin the installation.
Remove junction box. The elec-
trical 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).
Hook up electrical. Electrical
hook up should be done by a
quali ed electrician, so that all electrical wiring will conform to your
local standards. This unit is suppled with a 120V pump. For 240V
pump operation, a 240V pump must be purchased. The fan and pump
receptacles will support both 120V and 240V installations. See the
wiring diagrams for 120V and 240V installations on the following
page.
IMPORTANT: When a single speed motor is used, do not use the
red lead on the receptacle and motor plug wiring. Tape off end of
both of the red leads.
CAUTION: Pump receptacle is for grounded evaporative cooler
pump only. Do not plug anything else into receptacle.
W ARNING: Make sur e that cooler cabinet is properly grounded
to a suitable ground connection for maximum safety.
Mount motor . Install blower motor in the motor mount yokes, adjust-
ing 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.
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 Speci 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 sections
join must be supported as well.
NOTE: You can separate the wet module
from the blower module by removing the 4
bolts (2 bolts in ADA35 and ASA35) from the
wet module side (Fig. 1)
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.

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
Y ou 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.

ow pipe in nipple to retain water. The
over ow 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.
Connect water supply line. Install
a sillcock and water valve on faucet
as shown by gure 6. Place the nut
and ferrule on the tubing and tighten
the nut until water tight. NOTE: Do
not connect the water supply to any
soft water applications.

will protect you from someone turning on
unit while you are working inside. This
should be done for your safety. Adjust
pulley to a larger diameter and readjust belt
tension, plug motor in, install inspection
panels, and retest amperage draw. Repeat
this process until correct amperage draw is
attained. Increasing motor pulley diameter
increases amperage draw. Decreasing motor pulley diameter decreases
amperage draw (see Fig. 9).
CAUTION: Do not operate cooler with larger amperage draw
than speci ed on motor plate.
NOTE: No attempt should be made to completely install this unit
without the aid of an electrician or someone familiar with testing
amperage draw. Failure to comply with these instructions may void
your warranty.
Bleed-Off
Installation of the bleed-off kit is recommended to increase the life of
the cooler. A bleed-off system is designed to prevent scale build up by
continually removing a small percent of the water in the pan.
Install Bleeder Tee and Tub-
ing. Refer to gure 8. Cut the
pump hose and insert the barbed
ends of the bleeder tee into each
cut end. Insert one end of the
bleeder tubing onto the bleeder
tee and run the other end out of
the cooler through the over ow
pipe. Note: A restrictor clamp is
provided which, if desired, may be installed onto the bleeder tubing
to restrict the amount of water being bleed off. The amount of water
to bleed off depends on the quality of the water in your area. Start
with 1-2 gal/hr and increase if needed.

Maintenance
WARNING: Before doing any maintenance be sure power
is off. At the time you remove either inspection panel be sure to
unplug motor and pump. This is for your safety.
Spring Start-Up
Clean pads. A clean pad is more absorbent, ef cient and will give
more cool air. Annually, or when required, using a garden hose with
nozzle, back wash to clean out the openings, then clean off the inlet
face any scale or other obstruction to the passages. Slight scraping
may be required to remove hardened scale.
Change pads if necessary . The pads should be replaced after 5 years
or if necessary. To change pads, remove top access panel, remove
grill, and disconnect water delivery tube. Remove water distributor
holder and lift out media sections. Replace with the same type media.
You can purchase them from your dealer.
IMPORTANT: In order to get the best performance from your cool-
ing pads, they must be installed properly. If you have purchased a pad
with two equal angles, the following instructions can be disregarded.
Pads must always be installed with the steeper ute angle sloping down
towards the air entering
side (Fig. 10). The reason
is simple. The steeper
angle puts more water on
the hot, dry, dirty side of
the pad where it is needed
most. It also counteracts
the tendency of the air to
push the water toward the
back of the pad.
Amperage Draw And Belt Tension
This unit is equipped with an adjustable motor drive pulley for adjusting
the blower wheel speed to the proper loading on different duct systems.
It is important that the motor drive pulley is adjusted to correct size to
assure maximum air delivery without damage to the motor. Be sure to
follow these instructions carefully.
Adjust drive pulley. After the unit is completely installed, adjust
the drive pulley to the least diameter and adjust belt tension. See the
maintenance section for adjusting belt tension.
Start cooler. Install both inspection panels, start pump, and allow to
operate until pads are wet.
Check amperage. With pads wet and unit started, check amperage
draw with an amperage meter.
Adjust pulley if necessary . If amperage draw is less than motor rat-
ing, turn off electrical power and remove inspection panels (top pan
for models ADA35 and ASA35). Unplug motor inside cooler, this

Check belt tension. A 3 lb. force
should de ect the belt 3/4 inches (see
Fig. 11). Readjust belt if needed.
Oil bearings. The blower bearings and
cooler motor in this unit should be oiled
with a few drops of non-detergent 20/30
weight oil once each year. The motor
does not need oil if it has no oil lines for oiling. Motors that have no
oil lines are lifetime oiled at the factory and require no further oiling
for the life of the unit.
CAUTION: Do not over oil. Over oiling can cause motor burn
out, due to excessive oil getting into motor winding.
Clean pump. Cleaning the
pump is necessary once a year
at start-up. For your safety,
turn unit off and unplug motor
and pump. Remove the pump
from the mount slot. Remove
the base of the pump as shown
in Fig. 12. Clean the pump and
turn the impeller to ensure free
operation. Remove the pump

spout and check for any blockage. After cleaning, reinstall the base
onto the pump. Press rmly to make sure it is secure. Reattach the
pump to the mount in the cooler using the plastic retainer to ensure
that the pump will not overturn. Do not forget to replace the spout
and water delivery tube onto the pump outlet.
Check bleed-off valve to be sure it is not clogged.
Winter Shut-Down
Drain water . Always drain all of the water out of the cooler and water
supply line when not in use for prolonged periods, and particularly
at the end of the season. Keep the water line disconnected from both
the unit and water supply so that it does not freeze.
Unplug motor and pump. When cooler is not used for extended
periods unplug the motor and pump from inside cooler.
Cover unit. To protect the life of the nish, a cover for the unit is
suggested in extended periods of non use.
By following the operating, installation, and maintenance suggestions
as outlined, you ca n get many years of efficient and satisfactory service
from your cooler. In the event additional information is desired, your
dealer will be more than glad to assist you in every possible way.
