head. Repeat the test several times

 

 

 

 

 

to confirm a consistent volume of

 

 

 

 

 

dispensed water. If not consistent,

 

 

 

 

 

check the valve, tubing and spray-

 

 

 

 

 

head for lime buildup.

a consistent volume of dispensed

 

 

 

 

 

water. If not consistent, check the

 

 

 

 

 

valve, tubing and fittings for lime

 

 

 

 

 

buildup.

 

4.

Lime buildup

 

Inspect for lime buildup that could

 

 

 

 

 

block the tank, tank fittings, tubing,

 

 

 

 

 

valves and sprayhead.

 

5.

Brew volume adjustment

 

Adjust the brew volume, calibrate

 

 

 

 

 

sprayhead and bypass as required

 

 

 

 

 

to achieve the desired volume for

 

 

 

 

 

each brew cycle.
