Safety Rules

  1. Read instructions carefully.
  2. Disconnect all electrical service that will be used for the unit before you begin the installation.
  3. Electrical hook-up should be done by a qualified electrician so that all electrical wiring will conform to your local standards.
  4. For a maximum safety precaution, make sure the cooler cabinet is properly grounded to a suitable ground connection.
  5. The cooler must be connected to proper line current, voltage, and cycle, as stamped on cooler motor and pump motor specifi cation plate.
  6. Do no allow pump to tip over and become submerged.
  7. Always DISCONNECT POWER before installing unit or performing any maintenance.

Operation

For the best cooling performance, if the pads are dry, pre-wet the pads by running the pump for a few minutes before starting the blower. These coolers may also 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.
IMPORTANT: To cool efficiently, you must exhaust the stale or used air from the building. Open windows or doors or use exhaust fans located away from the cooler and in the direction you wish to cool the air. The air will fl ow in the direction of the exhaust openings. A common guide for the amount of exhaust opening needed is to have at least 2 square feet of opening per 1000 CFM.

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 plug in the cooler until installation is complete and the unit has been tested for rigidity.
CAUTION: Make sure all bolts are securely tightened before starting the cooler.

  • Ductwork. See the General Specification table for the duct opening dimension for your specific cooler. For down discharge units models 10/12DD and 14/21DD, the duct must go inside the opening. Size these ducts slightly smaller than the duct opening in the cooler. On 75/85DD and 95DD models the duct may go to the inside or outside of the duct flange. The side discharge units have a 1 inch flange. Size these ducts larger than the duct opening to fi t over the flange of these units.

Note: Curbs are not provided. The installer is responsible for providing curbs or other means to support the cooler.

Motor Installation

  • Mount motor. Slide the heads of the provided carriage bolts into the slots of the adjustable channels. Slide these channels sideways in the slotted holes to align with the holes in the motor base and to align the motor shaft with the blower pulley. Mount the motor to the motor mount using these carriage bolts and the washers and nuts provided (see Fig. 1). Make sure all bolts are securely tightened.
  • Install pulley. Install the adjustable motor pulley so that it aligns with the blower drive pulley (see Fig. 2) and tighten set screw. See page 3 for instructions on adjusting pulley.

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.

  • Electrical Supply. Cooler must be supplied with the proper line current, voltage and frequency, as stamped on the cooler motor and pump motor specification plate. See the wiring diagrams on page 4 for typical electrical connections. NOTE: Connecting improper voltage to motor will void motor warranty.
  • Wire sizing. The conductor sizes are to be determined by motor loads and length of run per national and local electrical codes.
  • Switches or contactors. Motors require switches or contactors of proper current capacity and should be sized and installed by a competent electrician.

WARNING: Make sure that cooler cabinet is properly grounded to a suitable ground connection for maximum safety

Water Connection

  • 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. 3). Screw on nut and draw up tight against the 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.
  • Pump. The pump must be secured to prevent it from tipping over. Secure the pump to the pump mounting bracket. For the 10/12 and 14/21 models, remove the mounting screw on the top of the pump and using this same screw, secure the pump to the pump mount. To secure the pump for the 75/85 and 95 models, slide the pump into the slot of the pump mount and secure it with the plastic retainer.
  • Water Supply. Run a water supply line to the unit. The float valve requires a 3/8-inch tube connection. NOTE: Do not use water supplied from a water softener.
  • Float valve. Install the float valve to the mount bracket in the cooler (Fig. 4) and attach the water supply line. Note: 75/85 and 95 units come with the float valve installed. For the other models, the fl oat is purchased separately.
  • Filling pan. Turn on the water supply and check for leaks. Allow water to fall to within 1” of top of the pan. Loosen the screw on the float rod to adjust the float and retighten the screw.
  • Water troughs. Operate the pump until the pads are saturated. Check each trough to see if water is evenly dispersed in the trough. If they are not, loosen the adjustment bolts and level trough. Retighten bolts. Check to see that all pads are saturated with water and that there are no dry spots or openings in the pads.
  • Bleed-Off. Use of a 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

Pulley And Belt Adjustments

  • Pulley adjustment. With an ammeter, check the motor amperage. Adjust the pulley until the amperage drawn on the motor is just below that specified on the motor nameplate. To adjust the pulley, loosen the adjustment set screw and rotate the sheave. Tighten the set screw so that it is over a flat area, otherwise, thread damage will occur. To increase amperage draw, increase pulley diameter. To decrease amperage draw, decrease pulley diameter (Fig. 5). Recheck belt alignment.CHAMPION-14SD-Industrial-Commercial-Evaporative-Cooler-fig \(4\)
    CAUTION: When it is necessary to adjust the pulley, the amperage of the motor must be checked to make certain it does not exceed the maximum allowed as stamped on motor specification plate. Improper pulley adjustment will overload and burn out motor.

  • Belt tension. Loosen the motor mount bolts and slide the motor back until the belt is properly tensioned. A 3 lb. force should deflect the belt 3/4 inches (see Fig.
    6). Retighten motor mount bolts. Do not adjust the pulley to tighten the belt.

Maintenance

WARNING: Before doing any maintenance be sure to disconnect from the power source. This is for your safety. Spring Start-Up

  • Belt tension. Check belt tension and readjust if needed.

  • 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.

  • Change Pads. The 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.

  • Clean pump. Cleaning the pump is necessary once a year at startup. For your safety, disconnect from the 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 with the pump outlet. The pump has automatic reset thermal protection. The pump will operate normally again after the obstruction is cleared.

Bleed off. Check the 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 it does not freeze.
  • Disconnect from the 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 nonuse.
    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.
