Troubleshooting

Foreword

This Troubleshooting Guide has been developed to 
assist you in determining what the probable cause for 
any particular problem you may experience with your 
Multiplex Beermaster Beverage System could be. It 
then advises of the proper corrective action to be 
taken to remedy that problem.

Because of the ever present danger from electrical 
shock, and the existence of high pressure water and 
gas on the system, it is strongly recommended that 
only qualified service personnel perform actual 
repairs.

Under each of the sections, Section 1: Restriction and 
Section 2: Beermaster Glycol Chiller System, you’ll 
first find the problem listed in bold type starting on the 
left margin. It will be followed by three headings also in 
bold type and each with its own column. The first is a 
“Qualifier” which is designed to quickly qualify or 
eliminate the “Symptoms” listed to the right and below 
the qualifying statement. For example, under 
Section 2: Glycol Chiller System, you’ll find “Too little 
restriction” for the same problem, “A recovery 
problem...”; “Since the recovery problem symptoms 
simulate a low pressure problem,...”. Each asking you 
to determine if “beer had been drawn” before 
proceeding to the second column “Symptoms”. Not all 
problems have recovery problems. For those that do, 
first examine each one listed below “Qualifier” before 
continuing through “Symptoms”. The third heading, 
“Corrective Steps” (found on the far right margin), will 
direct you in determining if the symptoms are actually 
responsible for the problem and what should be done 
to remedy the problem.

On occasion, you’ll find “Note” and “Caution” 
statements which have been included to make special 
references to items which frequently are 
misunderstood or ignored.
