Installation and Service Manual OPERATION CARBONATION The purpose of the carbonator is to take regular tap water at street water pressure (minimum 20 PSI dynamic or flowing pressure) 1/2” water line and increase the water to beverage system pressure (usually 100 PSI). This water is then combined with the CO2 gas. Because the water and gas are at the same pressure, the CO2 will dissolve into the water. Chilling the mixture before dispensing will assist in locking the carbon dioxide into the water.
Installation and Service Manual OPERATION BACK ROOM PACKAGE 1. Incoming tap water - should be at a minimum dynamic pressure of 40 psi and maximum static pressure of 55 psi. 7. Primary pressure regulator - Lowers the CO2 gas pressure, to 100 psi, so the CO2 gas will be at the proper pressure to enter the carbonator regulator. 2. Carbonator Water pump motor - Powers the water pump. The water pump motor is part of the carbonator pump deck. 8. Lowered outgoing pressure - Set for 75 psi.
Installation and Service Manual OPERATION 115V/220V NON ADJUSTABLE AGITATION TIMER The agitation timer on this unit is equipped with test pins.
