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 a swimming pool with the wind blowing, evaporative cooling makes you feel cool, even though the air may be warm.

The human body itself is cooled primarily by the evaporation of perspiration.

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

Manual Control Units

• Pump setting. The rotary switch has 6 settings. The “Pump” setting will operate the pump without the blower. For best results turn the switch to “Pump” for a few minutes to wet the pads before operating the fan.

• High and low cool settings. The “High Cool” and “Low Cool” settings operate both the pump and the blower. Turn the unit to “Low

Cool” when possible. This lower speed allows the air to stay longer in the wet pads and therefore increases it’s cooling effi ciency.

• High and low vent settings. The “High Vent” and “Low Vent” settings operate the blower without the pump. This is useful on cool nights or at times when just a fan is desired.

Remote Control Units

These units may be controlled using the 3 buttons on the front panel of the cooler or with the remote control.

• PUMP button. Pressing this button toggles the pump on and off.

When the LED is lit, the pump is running. For best results turn on the pump for a few minutes to wet the pads before operating the fan. The pump must be on while operating the fan for cooling.

You may also want the pump turned off at times when just a fan is desired.

• FAN button. Pressing this button will cycle the fan through High

Speed / Low Speed / Off. The LED’s on the front of the control indicate wether the fan is on high speed, low speed or off (no LED’s lit). Note: There will be a 2 second delay between a button press and the operation of the fan.

• ON/OFF button. Pressing this button while the pump or fan is on will turn everything off. Pressing it again while in the off state will return the fan and pump to their previous operating settings. When fi rst plugging in the cooler or after power has been interrupted, pressing the On/Off button will start the cooler in the default state which is with the pump on and the fan on high.

• Remote Control. To operate the cooler with the remote you must be within 20 feet and in sight of the cooler. Aim the remote at the front panel. The buttons on the remote control have the same functions as the buttons on the front panel of the cooler. The remote uses two AAA alkaline batteries which are included. A holder for mounting on a wall is also included with the unit.

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 method will help you determine the amount to open your windows.

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.

2

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

Installing House Legs

• NOTE: If installing unit without the use of the installation kit, omit these directions and those pertaining to Fig. 2.

• Remove two corner screws in the bottom pan (A-Fig 1).

• Place the house leg bracket in the corner of the bottom pan, using the two top holes in the bracket (B-Fig 1).

• Position cooler in win-

dow. Position neck of cooler so that bottom of neck fl ange rests on window sill and fl ange

(E-Fig. 2) is snug against edge of sill (H-Fig. 2). With cooler in position, hook the “S” hooks into the holes of the top pan near the back of the cooler (B-Fig. 2).

• Break fi ll-in panels to fi t. With cooler installed, as described above, measure for each window fi ll-in panel and score with sharp knife and straight edge guide to desired width. To break window fi ll-in panels, the panel should be laid over the edge of a straight fl at surface at the point to be broken off. Apply pressure on the edge of the panel that extends over the edge of the surface and break off unwanted piece.

• Install fi ll-in panels. Place one window fi ll-in panel on each side of grill and into panel retainer strip at bottom of grill. Place the other panel retainer strips onto top of neck fl ange and fi ll-in panels.

Be sure the panels are snug up against cooler neck.

• Place window behind retainer strip. Raise back of cooler so that the window (D-Fig. 2) may be brought down behind top of panel retainer strip (C-Fig. 2).

• Level Cooler. Adjust the chains to level the cooler.

• Adjust house legs. Pull out house legs so that the rubber bumpers rest against house siding (F-Fig. 2). Tighten screw in retaining collar. (G-Fig. 2).

Connecting Water

• Install overfl ow 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. 4). Screw on nut and draw up tight against bottom of pan. Insert overfl ow pipe in nipple to retain water. 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.

Maintenance

WARNING:

Before doing any maintenance be sure power is off and unit is unplugged. 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 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.

3 Lb.

3/4 Inches

• Check belt tension. A 3 lb. force should defl ect the belt 3/4 inches (see

Fig. 7). Readjust belt if needed.

Fig. 7

• Clean pump. Cleaning the pump is necessary once a year at startup. For your safety, turn unit off and unplug from power receptacle.

Remove the pump from the mount slot. Remove the base of the pump as shown in Fig. 8. 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 fi rmly to make sure it is

Remove

Base 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.

Fig. 8

Impeller

• Replace Pads. Aspen 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 effi cient and will deliver substantially more cool air.

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.

• Cover unit. To protect the life of the fi nish, a cover for the unit is suggested in extended periods of non use.

110496-1 3

• Cover grill. To help keep out cold air you can use the optional plastic grill cover. This cover may be purchased from your local distributor. To install the cover, line up the grill cover with the grill so that the tabs on the cover will slide over the center section of the grill. Slide the grill cover onto the grill. The tabs will snap into place. To remove, just pull the grill cover straight forward away from the grill.

• Unplug unit from power supply during extended periods of non-use.

By following the operating, installation, and maintenance suggestions as outlined, you can get many years of effi cient 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.
