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.

Kit contents

Removing the old thermostat relay

1. Turn “off” power to unit and all control switches on unit.

2. Remove access cover from Switch/Control Box and remove

cover from thermostat.

3. Disconnect wires from thermostat. Cut fork terminal from

compressor lead wire; strip and attach

/4" quick discon-

nect terminal.

4. Remove Thermostat Control Capillary from plastic mount

attached to evaporator. Remove two (2) screws securing

Control to Switch Box and remove Control.

Installing the new thermostat relay

1. Attach new Thermostat Control to outside of Switch Box

using same mounting holes and installing screws from in-

side of box.

Note: Control knob should be facing switch end of box.

2. Insert plastic bushing in hole in rear of box. Route capil-

lary through hole in end of Switch Box and secure to plas-

tic mount with plastic ties.

3. Install the Thermal Relay. Mounting holes for the thermal

relay are directly above the terminal block. Holding the

Thermal Relay with the base tab to the lower left and the

base hole to the upper right, the tab will slip into a hole

on the lower left. Secure the relay with a No. 8 screw

through the upper right hole.

4. Connect black wire from refrigeration switch to No. 2 ter-

minal on thermostat.

Note: Terminal numbers are on plastic block next to termi-

nal.

5. Connect brown wire from thermal relay to No. 3 terminal

on thermostat.

6. Connect black wire from compressor No. 2 to thermal re-

lay. This is the same wire modified in step 3 above.

7. Connect black wire from terminal No. 1 on thermal relay

to upper “live” terminal bank on terminal block.
