Safety Rules
- Read instructions carefully.
- Disconnect all electrical service that will be used for the unit before you begin the installation.
- Electrical hook up should be done by a qualified electrician, so that all electrical wiring will conform to your local standards.
- For a maximum safety precaution, make sure cooler cabinet is properly grounded to a suitable ground connection.
- Cooler must be connected to proper line current, voltage and cycle, as stamped on cooler motor and pump motor specification plate.
- Do no allow pump to tip over and become submerged.
- 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 flow 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 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 fit 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 cooler motor and pump motor specifi cation 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
- 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. 3). Screw on nut and draw up tight against bottom Overflow Pipe 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.
- 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 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 water supply line.
- Note: 75/85 and 95 units come with the fl oat valve installed. For the other models, the float is purchased separately.
- Filling pan. Turn on water supply and check for leaks. Allow water to fi ll to within 1” of top of pan. Loosen the screw on the float rod to adjust the float and retighten the screw.
- Water troughs. Operate pump until pads are saturated. Check each trough to see if water is evenly dispersed in the trough. If they are not, loosen 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 water.
Pulley And Belt Adjustments
Pulley adjustment. With an ammeter, check the motor amper-age. Adjust the
pulley until the amperage draw on the motor is just below that specifi ed 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.
CAUTION: When it is necessary to adjust pulley, amperage of 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 pulley to tighten belt.
Maintenance
WARNING
- Before doing any maintenance be sure to disconnect from 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 efficient and will deliver substantially more cool air.
- Clean pump. Cleaning the pump is necessary once a year at startup. For your safety, disconnect 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. The pump has automatic reset thermal protection. Pump will operate normal again after obstruction is cleared.
- Bleed off. 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 it does not 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.
