CIP Procedure
CIP mode is designed to allow the continuous flow of water and cleaning solution through the system. As such, when the
selector switch is in Automatic mode CIP will not work when the switch is in manual mode and CIP is turned ON, the fill
sensors that normally turn the fill heads off are disabled. Cans can be placed under the 5 fill heads and when the start
button has been pushed, product will continue to flow even after the fill sensors have been contacted by liquid.
In addition to this, the filler will cycle into ‘foam’ position once every 80 seconds to clean the inside of the foaming valve
holes. The fill heads will then cycle off for 20 seconds to allow the fill valve coils to cool before cycling on again. This will
prevent the coils from overheating and potentially burning out. This sequence will be repeated for 30 minutes until
the stop button is pushed.
Notes on CIP:
Pressure – when flushing the system with water or cleaning solutions it is important to keep pump pressures
below 24 PSI. The fill valves will not open at pressures higher than this level. If the valves are over pressurized and
jammed shut the beer line will have to be de-pressurized before the valves will open again. For breweries with
automated CIP systems or large pumps on CIP reservoirs it will be necessary to use a by-pass valve to reduce CIP
feed pressure.
Temperature – when flushing the system with hot caustic for cleaning it is advisable to 1) keep solution
temperatures at 65 degrees Celsius or lower.
