Multiplex Beverage Equipment Installation Instructions for
Thermostat Relay Kit for
Beermaster Model 150 Glycol Chiller
P.N. 00214175
Introduction
The high amperage load across the contacts of the thermo-
stat in the Multiplex Model Beermaster 150 Glycol Chiller
coupled with the high ambient conductors, may cause burning
of contact points on the thermostat. This relay removes the
load from the thermostat so that the burning will not occur.
