Electrical Installation; Operation; Motor Installation - Champion MARQUIS 3000 DD Owner's Manual

OPERATION

To eliminate delivery of hot air when starting your cooler, first
turn the pump on 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
3654 CFM, model 4800 DD requires 7.3 square feet (1052 square
inches) of opening (3654/1000 * 2 = 7.3). 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 7.3 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 open-
ing. 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.
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 Specifica-
tion Table.)
CAUTION:
Never plug in cooler until installation is com-
plete 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.
• Mount motor. Install blower motor in the motor mount yokes,
adjusting the yoke if necessary. Fasten with the provided mount-
ing clips (see Fig. 1).
• Install pulley. Install the adjustable motor pulley so that it 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. Remove
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.
CAUTION:
Pump receptacle is for grounded evapora-
tive cooler pump only. Do not plug anything else into
receptacle.
WARNING:
Make sure the cooler cabinet is properly
grounded to a suitable ground connection for maximum
safety.
