The motor will restart automatically when it cools down. ÊWARNING: To reduce the risk of fire or electric shock, do not use this fan with any “solid-state fan speed control device.” 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. This unit works on the same principle. Air is drawn across wet filter 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. 110498-3 9-09 Cooler Installation /KCAUTION: 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.) /KCAUTION: Never start cooler until installation is complete and unit has been tested for rigidity. /KCAUTION: Do not screw or drill within 5 inches of the bottom of the wet module. You could puncture the reservoir. /KCAUTION: 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: For ease of installation you can separate the wet module from the blower module by removing the 4 bolts from the wet module side (Fig. 1). Remember to unplug the pump and drain pump before separating the modules. 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. 2). Screw on nut and draw up tight against bottom of pan. Insert overflow into nipple to retain water. The overflow pipe comes from the factory connected to the dump pump hose. The 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. Install a sillcock and water valve on faucet as shown by figure 3. Place the nut and ferrule on the tubing and tighten the nut until water tight. NOTE: Do not connect the water supply to any soft water applications. Install float valve and fill pan. Refer to Fig. 4. 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. Connect to float fitting and tighten until water tight. Bend rod (6) to adjust float until water level is about 1 inch below the top of the overflow pipe. Slide float shield (7) over float body (5) until it snaps into place.

The control box is factory wired and installed for either 120 V or 230V operation depending on the model you purchased. The supply power should be adequately protected against overloads and short circuits. Note: Electrical installation should be performed by a qualified electrician. Be sure to follow all National and Local Electrical Codes when installing this co...
