Part Number STH13 9/10

This guide is intended to assist you in locating the 
cause of a problem. It is not, however, to be 
considered a service and repair manual in that 
Multiplex models vary in design.

It has been written to encompass all model 
Beermaster Glycol Chillers. Some differences from 
model to model will become obvious and it will be 
required of the reader to apply this guide to each unit.
