•Install float and attach water line to float. The float may be installed in either the corner post or bracket (see Fig. 9). If you have model 3000DD/N31D then the float should be mounted to the bracket. Refer to figure 10 for installation instruc- tions. Insert the float (1) thru the hole in the corner post or bracket. Install the washer (2) and nut (3). Tighten to keep the float from turning. Place the nut (5) and ferrule (4) on the water supply line. Connect to float fitting and tighten until water tight.
•Fill pan. Allow water to fill to within 1” of top of pan and adjust
float to maintain this water level. This can be accomplished by bend- ing the float rod.
• Level water troughs. Operate |

safety. Adjust pulley to a larger diameter and readjust belt tension, plug motor in, install pad frame, and retest amperage draw. Repeat this process until correct amperage draw is attained. Increasing motor pulley diameter increases amperage draw. Decreasing motor pulley diameter decreases amperage draw (see Fig. 12).
CAUTION: Do not operate cooler with larger amperage draw than specified 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 a pad frame be sure to unplug motor and pump. This is for your safety.

Installation of the
• Install Bleeder Tee and Tubing. Refer to figure 11. Cut the pump
hose and insert the barbed ends
of the bleeder tee into each cut
end. Insert one end of the bleeder tubing onto the bleeder tee and run the other end out of the cooler
through the overflow pipe. Note: A restrictor clamp is 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
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 all pad frames, 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 |

CAUTION: Do not over oil. Over oiling can cause motor burn out, due to excessive oil getting into motor winding.
•Change Pads. The pads should be replaced once or twice a season, de- pending upon the length of the season. At the beginning and at mid season a clean pad is more absorbent and efficient 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.
•Unplug motor and pump. When cooler is not used for extended periods, unplug the motor and pump from inside cooler.
•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.
