Pads must always be installed with the steeper flute angle sloping down towards the air entering side (Fig. 7). The reason is simple. The steeper angle puts more water on the hot, dry, dirty side of the pad where it is needed most. It also counteracts the tendency of the air to push the water toward the back of the pad. 3 Lb. 3/4 Inches Check belt tension. A 3 lb. force should deflect the belt 3/4 inches (see Fig. 8). Readjust belt if needed. Fig. 8 • 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. ACAUTION: Do not over oil. Over oiling can cause motor burn out, due to excessive oil getting into motor winding. • Clean water pump and dump pump. Cleaning both pumps is necessary once a year at start-up. For your safety, turn unit off and unplug motor and pumps. Remove the pump from the mount slot. Remove the base of the pump as shown in 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. Press firmly to make sure it is secure. Reattach the pump to the mount in the cooler using the plastic retainer to ensure that the pump will not overturn. Do not forget to replace the spout and water delivery tube onto the pump outlet. 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 pumps. When cooler is not used for extended periods unplug the motor and pumps 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. 4 110498-3 Troubleshooting Guide Problem Possible Cause Remedy 1.

Check that wiring is correct and secured to terminals 6. Check connections to terminal 7. Supply power to control box and check DC voltage at wall thermostat • If voltage between Black & Red terminals is close to 3.5VDC and LCD is blank - wall thermostat is faulty • If voltage is much less than 3.5VDC, remove red wire from terminal. If voltage rises to 3.5VDC - thermostat is faulty. If voltage remains low - unit control board is faulty. Inadequate 1. Insufficient air exhaust 1. Open windows or doors to 2. Belt too loose 3.
