This build up Figure H narrows the inside diameter of the tubes and will restrict the product flow and will slowly offset the brix Proper cleaning of the pump system will help prevent and correct this condition 1 Remove the product containers from the dispensing cabinet Replace each container with any clean contain er Same capacity as product container filled with warm water 40 45 C and insert product pick up tubes Page 8 Crathcoe Post Mix Beverage Dispensers 3 into clean container see figure H Close the cabinet door and dispense the warm water the same way as it would be a product Dispensing should last for no longer than 90 seconds Repeat the above for all remaining dispensing stations Washing Parts Proceed as described in Wash Parts without flushing Sanitizing Prepare sanitizing solution per instruction on the package changing the strength of the solution to be equivalent to 6 1 e g If instruction calls to dilute contents of the sanitizer package in 4 liters of water use only 0 6 liters of the water for the solution Fill the clean container that was used for tubing cleaning with the sanitizing solution 1 2 Install container with sanitizer solution in the cabinet and connect pump tubing to product pick up tube assembly Close the cabinet door and depress dispensing switch corresponding with position of the container with sanitizing solution for 15 seconds Wait 3 minutes Lift
3. water cooling system do not require manual adjustment or settings There are no Electromechanical thermostats to control the cooling systems The cabinet cooling system is a frost free system that maintains not only desired temperature but also a constant humidity level in the cabinet with exception to the time when the cabinet door is open The dispensing buttons are located on the front panel and are easily accessible by the operator The system is powered with safe 24 VDC as well as a water inlet solenoid valve and an electronic controller The machine has accessible modular construction and has been designed to be simple yet effective to provide many years of trouble free operation Page 2 Crathcoe Post Mix Beverage Dispensers INSTALLATION Installation Notice A water filter is recommended for the water supply to the dispenser especially in areas where water contains a high level of minerals such as calcium or other solids Over long periods of time calcium deposits build on heat exchanger coils and will lower the cooling capacity of the system Calcium build up will also occur on the strainers enclosed in the dispensing valves The cooling system is provided with copper coils designed to last the life of the dispenser However some chemicals in treated or not treated water specifically chlorine and sulfur sulfide may shorten the life of the coils The initial investment in the filtering system will pay for itself in quality and b
