ELECTRICAL INSTALLATION INSTRUCTIONS - ALL MODELS

NOTE:

 Electrical source should have a circuit breaker between the brewer and the main supply which breaks all 

poles with a contact separation of at least 3 mm.

CAUTION – 

Improper electrical installation will damage electronic components.

1.  An electrician must provide electrical service as specified.

2.  Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.

3.  Before electrically connecting the brewer, remove the front cupola cover (some models have the thermostat 

knob on the outside of the cover) and rotate the thermostat knob fully counterclockwise to the "OFF" position. 

Keep this knob in the "OFF" position until performing the 

Initial Setup

.

4.  Electrical service is connected at the upper rear of the single service and scrambler brewers using a junction 

box. On double service brewers the rear decorative channel must be removed for access to the terminal block.

5.  Connect the brewer to the power source and verify the voltage at the terminal block before proceeding.   Re-

place all panels.

6.  If plumbing is to be hooked up later be sure the brewer is disconnected from the power source.  If plumbing 

has been hooked up, the brewer is ready for 

Initial Setup

.
