1. Is it okay to add ice to the unit? Answer: Adding ice or ice water does not damage the unit in any way. However, we have made numerous studies after adding ice, and find that the outlet temperature (at the vents) drops an additional 7 degrees for about 20 minutes. Then the temperature rapidly climbs to the point reached before adding the ice. 2. What problem does overfilling cause? Answer: Filling the unit beyond the red mark on the water level indicator reduces the angle that the cart can be operated without any water spilling over the top, The evaporative cooler is an open system, and the unit is designed to tilt about 30 degrees when the water tank is filled to the red mark. Filling beyond this mark reduces the angle at which the cart can operate without spilling water over the top. 3. Does it damage the unit to run it without water? Answer: No. The pump has nylon bearings that can operate dry without damage. 4. Should water be left in the unit over the winter? Answer: We recommend that the unit be drained during the winter months, but it is not necessary. 5. How do you drain water from the unit? Answer: Use a four or five foot piece of 3/8" or ½" tubing to siphon the water. Vinyl tubing can be obtained at most hardware stores. 6. How often should my "COOL BREEZE" unit be serviced? Answer: We recommend service once per year (unless of course, your unit isn't operating properly). 7. What does this "annual service" cover? Answer: Replacing the filter, replacing the copper manifold, and checking the water pump. These items are important for proper (and efficient) operation of the unit. 8. How long does a tank of water last? Answer: About 8 hours, depending on the region in which you live. Typically the water will last enough for three or four rounds of golf. 9. How much load does the unit place on the batteries when operating? Answer: The unit draws 6 amps, or about the same amount of energy as one headlight for your cart. You will probably never notice any effect on your battery condition from operating the COOL BREEZE unit. 10. Who do I call if I have additional questions? Answer: Call the dealer where you purchased the unit, or feel free to call the factory direct at (760) 340-6131, Monday through Friday, 8:00 am to 4:30 pm PT. In order for optimal performance from your COOL BREEZE unit you must have a yearly service performed. All maintenance kits are supplied by your local distributorship. To locate your closest distributor for maintenance service please call COOL BREEZE directly Toll Free at (866) 674-COOL. The Yearly Service kits include the following: Water Manifold - This copper tubing is used to circulate the flow of water onto the cool pad filter. Filter - This Coolpad non-allergenic filter creates the evaporative cooling. Without this filter working properly there will be no evaporative effects. That is why it is very important to replace the filter once per year. The only regular service to the COOL BREEZE unit is the addition of water. There is no specification for the type of water to use. Tap water is fine, and there is no problem with adding ice cubes to the unit. By adding ice the COOL BREEZE air top will perform at its maximum potential. There is no need for distilled or bottled water. It is important that the unit be filled only until the red line appears on the water level indicator located on the fill pipe under the fill cap. If felt necessary to clean water in tank, take one-to-two teaspoons of lemon juice or bleach and add to the water tank. This will do no internal harm to the unit.
