SAFETY RULES
1. Read instructions carefully.
2. Electrical hook up should be done by a qualified electrician,
so that all electrical wiring will conform to your local
standards.
3. Always turn OFF POWER and UNPLUG motor and pump
inside the cooler before installing or performing any
maintenance.
4. Your cooler will run on 120 volt AC., 60 Hz (cycle) current
only.
5. Motor and pump have a grounded, molded plug and an
automatic thermal overload switch which will shut motor off
whenitoverheats. Themotorwillrestartautomaticallywhen
it cools down.
WARNING: To reduce the risk of fire or electric shock,
do not use this fan with any “solid-state fan speed control
device.”
READ AND SAVE THESE INTRUCTIONS EVAPORATIVE COOLING
With this unit being a fresh air system, you are not trapped
with recirculating air that can become stale, laden with smoke
and odors, as happens with refrigerated air conditioning
systems. Instead, you are completely replacing the air every
2 to 4 minutes by either opening doors or windows or a
combination of both to exhaust the air continually.

OPERATION
To eliminate delivery of hot air when starting cooler, turn on
pump only for the first 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.

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 3077 CFM, model 4300 DM requires 6.2 square
feet (886 square inches) of opening (3077/1000 * 2 = 6.2).
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
6.2 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.
• Onceyou balance your home you cancool 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.
INSTALLATION
NOTE: The pump and float are installed in the cabinet. The
belt, motor pulley, and motor cord are included in the cabinet,
the motor is shipped separately.
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.
MOTOR INSTALLATION
•Install motor cord. Connect motor cord to motor using the
following color code: Black - Hi, Red - Low, White - Com.,
Green - Ground.
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

aligns with the blower drive pulley (see Fig. 2) and tighten
set screw.
ELECTRICAL INSTALLATION
WARNING: Disconnect all electrical service that will
be used for this unit before you begin the installation.
•Remove junction box.
The electrical junction
box is located in the up-
per inside corner of the
cooler cabinet. Re-
move the two screws
and slide cover down for
access to plug wiring (Fig. 3).
•Hook up electrical. Electrical hook up should be done by a
qualified electrician, so that all electrical wiring will conform
to your local standards. See Fig. 4 for the wiring diagram.
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.

•Connect water supply line.
Find the closest supply of wa-
ter. Use a saddle valve (Fig. 6)
to connect 1/4” tubing to the
cold water supply or use a
Sillcock and water valve con-
nected to an outside faucet
(Fig. 7). Place the nut and fer-
rule on the tubing and tighten
the nut until water tight. IM-
PORTANT: Donotconnectthe
water supply to any soft water
applications. Soft water will
cause corrosion and de-
crease the life of the cooler.
•Attach water line to float.
Attach the water supply line
to the float in the same man-
ner as above. The float may
be installed in either the cor-
ner post or bracket (Fig. 8).
•Fill pan. Allow water to fill to
within 1” of top of pan and ad-
just float to maintain this
water level. This can be ac-
complished by bending the
float rod.
•Adjust water amount. Your
cooler is equipped with a
unique water metering valve (Fig. 9). The amount of water
delivered to the pads may be decreased by pressing the
plastic valve as the arrows indicate.
If water is splashing out of water
troughs, you may need to decrease
the amount of water delivery. Check
toseethatallpadsare saturated with
water and that there are no dry spots
or openings in the pads.
AMPERAGE DRAW AND BELT TENSION
This unit is equipped with an adjustable motor drive sheave
for adjusting the blower wheel speed to the proper loading on
different duct systems. It is important that the motor drive pul-
ley is adjusted to correct size to assure maximum air delivery
without damage to the motor. Be sure to follow these instruc-
tions 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 ten-
sion.
•Start cooler. Install all pad frames, 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 rating, turn off electrical power and remove pad frame.
Unplug motor inside cooler, this will protect you from some-
oneturning on unit whileyou are working inside. Thisshould
MAINTENANCE
WARNING: Before doing any maintenance be sure
power is off. At the time you remove a pad frame be sure
to unplug motor and pump. This is for your safety.
SPRING START-UP
•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 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
burnout,duetoexcessiveoilgettinginto
motor winding.
•Check belt tension. A 3 lb.
force should deflect the belt 3/
4 inches (see Fig. 11). Read-
just belt if needed.
•Change Pads. The pads should be replaced once or twice
a season, depending upon the length of the season. At the
beginning and at mid season a clean pad is more absorbent
and efficient and will deliver substantially more cool air.
•Clean pump. Clean-
ing 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 im-
peller to ensure free operation. Remove the pump spout
andcheckforanyblockage. Aftercleaning, reinstall the base
ontothepump. Reattach the pump to the mountinthecooler
using the plastic retainer to ensure that the pump will not
overturn. Do not forget to replace the spout and water deliv-
ery tube onto the pump outlet. The pump has automatic
reset thermal protection.

be done for your safety. Adjust pul-
ley to a larger diameter and readjust
belttension,plugmotorin,installpad
frame, and retest amperage draw.
Repeat this process until correct
amperagedrawisattained. Increas-
ing motor pulley diameter increases
amperage draw. Decreasing motor
pulley diameter decreases amperage
draw (see Fig. 10).
CAUTION: Do not operate cooler with larger amper-
age draw than specified 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 instruc-
tions may void your warranty.

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 boththe 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 finish, a cover for the
unit is suggested in extended periods of non use.
By following the operating, installation, and maintenance
suggestions as outlined, you can get many years of efficient
and satisfactory service from your cooler. In the event addi-
tional information is desired,your dealer will be more than glad
to assist you in every possible way.
