SUBJECT:

 

Brewer Spray Disk and Gasket Application 

 

A.  An revised spray disk (p/n 82727) and associated         
 

hat-shaped gasket (p/n 82215) comprise the  

 

latest in a series of ongoing improvements for: 

 
 E-Max™

 Coffee Brewers 

 E-Max 

T™

 Tea Brewers. 

 
 
 
 
 
 
 
 
 
 
     The hat-shaped gasket 

must

 be used with the new spray disk 

 on 

E-Max™ and E-Max T™ 

 
B. and C.

  (Omitted - refer to other equipment applications)

 

 

D.   

All current production Bloomfield Brewers  incorporate the 

 

embossed spray disk

 
E. 

The revised embossed spray disk has a different outflow rate 

 

than either the flat spray disk or old-style embossed spray 

 

disk.  When replacing a flat spray disk or old-style embossed 

 

spray disk with an revised embossed spray disk, the back-

 

pressure of the spray head will be changed.

 

 

     Note the altered flow rates for  E-Max™ when the new spray 
 

head is installed: 

 
     Before

 – Embossed spray disk and flat band gasket 

     Now

 – Revised embossed spray disk and hat-shaped gasket

F.

  Cleaning of tubing, elbows, strainers and spray disks have 

 

the potential to alter basic calibration settings of the brewer.  

 

Whenever the brewer has been disassembled, or when parts 

 

are changed, cleaned or adjusted, be sure to check all timed 

 

functions and reset as required for an optimal brew.
