Keg Washing Recommendations:

When first wiring in the system - be sure to verify proper motor rotation. Arrows on the back of the motor - show the proper rotation of the fan/motor. Reversing any (2) wires of a 3phase circuit - will change the rotation of the motor.

Be sure to regulate the Air and CO2 coming into the system to no more that 45 psi.

Be sure to purge CO2 before using a caustic based cleaner. - CO2 will neutralize caustic based cleaners

Reducing the flow of the cleaners - for a portion of the cycle - this will allow the cleaner to better contact the out- side of the stem

Multiple burst rinses - may be more effective that one long rinse - especially after the Det. Cleaner
