INSTALLATION OF EVAPORATIVE COOLERS PREPARATION 1. All electrical and duct work must comply with local and federal codes. 2. Make arrangements to get the cooler from ground to roof (crane, hoist, etc.). LOCATION 1. Cooler should not be mounted near exhaust openings or vent pipes where fumes and odors can be drawn into cooler. 2. Ensure mounting surface is strong enough to support the cooler. Operating weight will be much heavier than shipping weight. 3.
MOTOR PULLEY ADJUSTMENT Before installing the motor pulley, loosen the set screw on the back side of the pulley and turn the outside jaw of the pulley until it is fully closed. Position the set screw over the closest flat spot in the thread and then open the outside jaw of the pulley 4 or 5 turns. Position the set screw over the closest flat spot in the thread and retighten the set screw. Place the pulley on the motor shaft and tighten the front set screw. See figure 2.
START UP After installing cooler and before filling with water: 1. Open windows and doors or other exhaust openings in building. 2. Turn on cooler and check amperage at the incoming white lead, using clamp on ammeter. If amperage reads above motor name plate, refer to the motor pulley adjustment instructions (page 2) and open the pulley ½ turn. Restart cooler and recheck amperage. If amperage reads below motor name plate, close the pulley ½ turn. Restart cooler and recheck amperage. 3.
