INSTALLATION INSTRUCTIONS (continued) 

NOTE:

  This equipment must be 

installed to comply with          
applicable federal, state and  
local plumbing codes and       
ordinances. 

 

 

WARNING: 

SHOCK HAZARD

  

 

Brewer must be properly 
grounded to prevent possible 
shock hazard.  DO NOT        
assume a plumbing line will  
provide such a ground.        
Electrical shock will cause death 
or serious injury. 
 

 

IMPORTANT:

 Do not connect 

brewer to electrical power until 
the tank is filled with water.  
Pour water into the pour-over 
opening until water flows from 
the brew head. 

 

IMPORTANT: 

Supply power must match 
nameplate for voltage and 
phase.  Connecting to the 
wrong voltage will damage the 
brewer or result in decreased 
performance.  Such damage is 
not covered by warranty.

 

NSF requires that the brewer be able to be moved for cleaning 
underneath.  A flex line or loops of copper tubing will satisfy this 
requirement. See Figure 2 below. 
 
 
 

 
 
 
 
 
 
 
 
 
 
 

In some areas, local codes require a backflow preventer  (check 
valve)  to be installed on the inlet water line.  If a backflow        
preventer is used, you must install a water hammer arrester in 
the incoming line, between the backflow preventer and the 
brewer inlet, as far away from the brewer as space will allow.  
This will relieve the excessive back  pressures that can cause 
faucet leaks and solenoid malfunctions.  
 

ELECTRICIAN’S INSTALLATION INSTRUCTIONS 

 

REFER TO ELECTRICAL SPECIFICATIONS  -  Page  1 

Check the nameplate to determine correct electrical service 
required for the Brewer to be installed. 

 

IMPORTANT:  

Before connecting to electricity, make sure    

automatic brewers are connected to the water supply.   

 

 

Brewers 

must be wired by an electrician, and require a dedicated 

115/230V  or 120/240V 20A circuit (50/60 Hz,  L1, L2, Neutral, 
plus ground).  Remove front panel to gain access to terminal 
block.  Green terminal must be connected to a suitable building 
ground.  Circuit must be capable of 4000 Watts (model 1090 and 
1092)  or 7000 Watts (model 1091 and 1093).  
See figure 3 at right. 

 

IMPORTANT:  

Wiring must be installed in approved solid or  

flexible conduit, and must be secured to the brewer with a strain 
relief (to be provided by the installer).
