Pulley And Belt Adjustments
•Pulley adjustment. With an ammeter, check the motor amperage. Adjust the pulley until the amperage draw 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 (see Fig. 6). Recheck belt alignment.
CAUTION: Always check the amperage of the motor after ad- justing pulley to be certain it does not exceed the amperage stamped on the motor specification plate. Improper pulley adjustment will overload and burn out the motor.
• Belt tension. Loosen the motor mount | 3 Lb. |
3/4 Inches | |
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. 7). Retighten motor mount bolts. | Fig. 7 |
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.
•Grease bearings. The blower bearings in this unit should be greased once a year with a good grade of ball bearing grease.
•Cleaning pads. A clean pad is more absorbent, efficient and will give more cool air. Annually, or when required, using a garden hose with nozzle, back wash to clean out the openings, then clean off the inlet face any scale or other obstruction to the passages. Slight scraping may be required to remove hardened scale.
•Pad replacement. The pads should be replaced after 5 years or if necessary. To change pads, remove top access panel, remove grill, and disconnect water delivery tube. Remove water distributor holder and lift out media sections. Replace with the same type media. You can purchase them from your dealer.
IMPORTANT: In order to get the best performance from your cool- ing pads, they must be installed properly. If you have purchased a pad with two equal angles, the following instructions can be disregarded. Pads must always be installed with the steeper flute angle sloping down towards the air enter-
ing side (Fig. 8). The rea- |
|
|
son is simple. The steeper |
| 45° |
angle puts more water on | Entering | Leaving Air |
the hot, dry, dirty side of | Air | |
the pad where it is needed |
|
|
most. It also counteracts |
| 15° |
the tendency of the air to |
| Fig. 8 |
push the water toward the |
| |
|
| |
back of the pad. |
|
|
•Cleaning pump. Cleaning the pump is necessary once a year at start- up. For your safety, disconnect from power source and unplug pump. Remove the pump from the mount bracket. Remove the base of the pump (Fig. 9). 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 au-Impeller tomatic reset thermal protection.
Pump will operate normal again after obstruction is cleared.
• Bleed off. Check
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.
