Operation

T o eliminate delivery of hot air when starting cooler , Start the pump without the blower 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.

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 Specification Table.)

CAUTION: Never start cooler until installation is complete

and unit has been tested for rigidity.

CAUTION: This unit must be installed at a height of 10 feet

or greater from the floor.

Electrical Installation

NOTE: Local building code regulations must be observed.

WARNING: Disconnect all electrical service that will be

used for this unit before you begin the installation.

• Connect electrical. Cooler must be connected to the proper line

current, voltage and cycle, as indicated on the decal located at the electrical service entrance. Connecting improper voltage to motor will void motor warranty. See the wiring diagrams (figures 8 & 9) on page 3 for wiring electrical connections. NOTE: A separate 120 Volt, 60 Hz, 1 phase pump electrical circuit is required to maintain the integrity of the GFCI pump protection and to maintain the U.L. Listing of the evaporative cooler.

• Wire gage. The horse power, voltage, cycle, phase, current, and

length of wire required from switch to motor will determine the gauge of wire to be used.

• Switches. Larger horsepower and three phase applications require

switches (not supplied) of proper current capacity and should be installed by a competent electrician.

• Power Supply box. The

power supply box is located in the upper inside of the divider channel. Remove the cover to access wiring. (Fig. 1). Connect wiring in box to power supply wiring as per wiring diagrams.

WARNING: Make sure that cooler cabinet is properly

grounded to a suitable ground connection for maximum safety.

Water Connection

• Pumps. Plug the pumps into the pump receptacles. There are

metal cord retaining clips on the corner post and motor cross braces for retaining the pump cords.

CAUTION: The pump cord must be secured to prevent it

from dropping into water reservoirs or contacting moving components.

• 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. 2). Screw on nut and draw up tight against bottom of pan. Insert overflow pipe in nipple to retain water. Overflow 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. A water supply line should be run to

the cooler to supply an adequate amount of cold water to the unit. The amount of water each cooler uses will depend on the weather conditions in your area and the size of your unit. The hotter and dryer your climate and the higher the capacity of your unit, the more water will evaporate. For example: An FAD248 unit with a 2 hp motor will use approximately 85 gallons per hour in a hot and dry climate like Las V egas on a 105°F day with 10% humidity . The same unit in a cooler climate with 95°F and 20% humidity would use approximately 63 gph. NOTE: Do not connect the water supply line to any soft water applications.

• Install float valve and fill pan. Refer to Fig. 3. Remove items 1,

2, 3, and 4. Insert float body (5) through hole in back post panel as shown. Install washer (1) and nut (2). Tighten to keep float from turning. Place nut (4) and ferrule (3) on water supply line. Con-

nect to float fitting and tighten until water tight. Loosen screw (6) and adjust rod (7) until water level is

within 1" of top of reservoir. Tighten screw (6). Slide float shield (8) up over float body (5)

until it snaps into place.

• Bleed-Off. Use of the bleed-off kit is recommended to prevent

scale build up by bleeding off small amounts of circulating water during operation. Do not add any type of water treatment chemicals to the water.

Maintenance

WARNING: Before doing any maintenance be sure to dis-

connect from power source. This is for your safety.

Spring Start-Up

• Check belt tension. A 3 lb. force

should deflect the belt 3/4 inches (see Fig. 4). Readjust belt if needed.

To adjust belt, loosen the two hinge nuts and the locking nut on the adjusting bolt as shown in figure 5. Loosen or tighten the adjustment nut until the belt is at the right tension. Lock the motor plate in place by tightening the locking nut and then tighten the 2 hinge nuts.

• Grease bearings. The shaft

bearings in this unit should be greased once a year with a good grade of ball bearing grease.

• Clean pads. A clean pad is more absorbent, efficient 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.

• Pad replacement. The pads should be replaced after 5 years or

before 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 cooling 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 flute angle sloping down towards the air entering side (Fig. 6). 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 coun-

teracts the tendency of the air to push the water toward the back of the pad.

• Cleaning pumps. Cleaning the

pumps is necessary once a year at start-up. For your safety, discon-

Remove

nect from power source and unplug pump. Remove the pump from the mount bracket. Remove the base of the pump (Fig. 7). 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. Reattach the pump to the mount in the cooler to ensure that the pump will not overturn. Do not forget to replace the spout and water delivery tube onto the pump outlet. NOTE: The pump has automatic reset thermal protection. The pump motor will stop if it overheats. The pump will operate normal again after obstruction is cleared.

• 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 water will not seep into the line and freeze.

• Disconnect from power supply when not in use for extended

periods of time.

• 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 additional information is desired, your dealer will be more than glad to assist you in every possible way.
