on for 30 seconds and collect the

 

 

 

 

water dispensed from the spray-

 

 

 

 

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.

 

 

4. Dilution valve

dilution value. Refer to test outputs

 

 

 

 

on page 56. Turn the valve on for

 

 

 

 

30 seconds and collect the water

 

 

 

 

collected from the nozzle. Repeat

 

 

 

 

the test several times to confirm

 

 

 

 

a consistent volume of dispensed

 

 

 

 

water. If not consistent, check the

 

 

 

 

valve, tubing and nozzle for lime

 

 

 

 

buildup.

 

 

5. Lime buildup

 

Inspect for lime buildup that could

 

 

 

 

block the tank, tank fittings, tubing,

 

 

 

 

valves and sprayhead.

 

 

6. Brew volume adjustment

 

Adjust the brew volume as required

 

 

 

 

to achieve the recommended vol-

 

 

 

 

ume for each brew cycle.
