This unit works on the same principle. Air is drawn across wet ﬁ 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 ﬁ rst few minutes, then turn on the blower motor.

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.

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.

• 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.

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.

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 Speciﬁ 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.

• Hook up electrical. Electrical

Fig. 4

hook up should be done by a qualiﬁ 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.

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 bottom of pan. Insert overﬂ ow pipe in nipple to retain water. The overﬂ 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 ﬁ gure 6. Place the nut and ferrule on the tubing and tighten the nut until water tight. NOTE: Do

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.

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

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

Decrease Amperage

tension, plug motor in, install inspection panels, and retest amperage draw. Repeat this process until correct amperage draw is

Fig. 9

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 speciﬁ 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.

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, efﬁ 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 ﬂ 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.

spout and check for any blockage. After cleaning, reinstall the base onto the pump. Press ﬁ 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.

• 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
