Newco gxdf-8d Operating Guide

3 

 Power to brewer must be OFF before proceeding with plumbing installation. 

 
1)  Flush water line before installing brewer. Brewer should be connected to COLD WATER LINE for best operation. 
 
2)  Water pressure should be at least 20 lbs. For less than a 25 ft run, use 1/4" copper tubing and connect to 1/2" or 
 

larger water line. For longer runs, use 3/8" copper tubing & connect to 1/2" or larger water line and provide an 

 

adapter fitting for connection to the brewer. 

 
3)  If installed with saddle valve, the valve should have a minimum of 1/8" port hole for up to 25 ft run, and 5/16" port 
 

hole for over 25 ft runs. 

 
4)  Connect incoming water line to the flow control device on the back of the brewer. Manufacturer recommends 
       connecting to copper tubing. 
 

 - Read and follow installation instructions before plugging or wiring in machine to electrical circuit. 

Warranty will be void if machine is connected to any voltage other than that specified on the name plate. 
 
 

Depending on the particular model, this brewer may be hooked up to either a 120/240V ac single phase circuit 

or a 120/240V ac three phase delta circuit. Refer to the brewer name plate on back of brewer. The pictorial view at the 
bottom of this page illustrates the power cord connection to the terminal block for both circuits. A wiring diagram at the 
rear of this manual illustrates the complete brewer wiring. Note that the tank heater system is the only portion of the 
brewer running on 240V. The balance of components are powered by 120V obtained by tapping one leg, L1, of the 
circuit. 
 
To attach power cord or conduit: 
 
1)  Remove the front access panel covering terminal block area by removing the four retaining screws. 
 
2 

Locate the strain relief connector on rear of unit and loosen the connectors two screws.  

 
3)  Feed appropriate power cord/conduit through the strain relief connector until wire leads reach the terminal block in  

front of brewer. 

 
4)  Make electrical connections as shown at the bottom of this page and on the wiring diagram at the rear of this 

manual. Before attaching leads to terminal block, turn screws on the bottom face of terminal block and on the earth 
ground connector fully counter clockwise to insure that the receiver for leads is fully open. Hold lead in place and 
tighten by turning screws fully clockwise. Tighten strain relief on rear of unit.
