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.

Installation

NOTE: The pump comes installed. The belt, motor pulley, and motor cord and float 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.

Remove junction box. The elec-

Hook up electrical. Electrical hook up should be done by a qualified 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. Note: Clip pump cord onto cord clip located on the bottom of the junction box to keep cord our of the water.

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.

WARNING: Make sure the cooler cabinet is properly ground- ed to a suitable ground connection for maximum safety.

• Install Duct Adapters. If desired, a 4 piece duct

adapter is available as an optional accessory.

Call 1-800-643-8341 to obtain these from the

factory. Align the holes in the duct adapter to the

holes in the blower opening and attach using the

provided screws (see Fig. 1). Repeat for all four

sides. Note: All 4 pieces are identical except for

models 5000SD & N55/65S which have an offset

piece which attaches to the bottom of the outlet.

To install this offset piece, remove the screws

holding the cut-off plate and slide the offset duct

adapter between the blower opening and the cut-

off plate. You may need to loosen other screws

Motor Installation

Install motor cord. For typical 120V op- eration, connect motor cord to motor using the following color code: Black - Hi, Red - Low, White - Com., Green - Ground. (See Wiring Diagrams)

Mount motor. Install blower motor in the motor mount yokes, adjusting the yoke if necessary. Fasten with the provided mounting clips (see Fig. 2).

Install pulley. Install the adjustable mo- tor pulley so that it aligns with the blower drive pulley (see Fig. 3) and tighten set screw.

Water Connection

Install overflow assembly. Place drain nipple

through the hole in the pan, with the rubber

washer between the pan and the head of the

drain nipple (Fig. 6). Screw on nut and draw

up tight against bottom of pan. Insert the

overflow pipe in the nipple to retain water.

The overflow pipe may be removed to drain

the pan when necessary. A garden hose may

be screwed on the drain nipple to drain water

away from your unit.

Connect water supply line. Find the

closest supply of water. Use a saddle

valve (Fig. 7) to connect 1/4” tubing to

the cold water supply or use a Sillcock

and water valve connected to an out-

side faucet (Fig. 8). Place the nut and

ferrule on the tubing and tighten the

nut until water tight. IMPORTANT:

Do not connect the water supply to any

soft water applications. Soft water
