Water supply pressure-reducer setting 

Adjust 

The set-up may include an optional pump

5

 but will always incorporate a pressure-reducer in the feed-

line to the machine, initially set to appr. 3.0 bar (45 psi). After getting used to the machine you may 
want to adjust this setting. If pre-infusion takes too long, increase the outgoing pressure of the 
reducer. Equivalently, when pre-infusion is too quick, lower the outgoing pressure. 

As mix-water temperature (also) depends on incoming water-line pressure, you need to check -and 
maybe adjust- this temperature after changing the pressure-reducer setting. 

 

Figure 19. How to adjust the Vesta pressure reducer setting; procedure for the AIGNEP version is 
similar. Pull the knob out and then twist to the correct setting. When done, push the knob back in. Note 
that the machine will not lose pressure due to one-way valves in the system. Set the outgoing 
pressure during an actual brew (not with a blind filter). 

Check 

Incoming pressure and functioning of gauges can be checked during pre-infusion. Prepare normal 
coffee-beds, lock-in and one by one pull the brew-levers into locking position. Check the highest 
pressure reached for all groups available (this will be incoming water pressure) and compare the 
results.  

Notes!

  

A small divergency (<0.2 bar) between the groups can be the result of deviations between pressure 
gauges and is no cause for alarm. 
A large divergency may indicate a gauge-malfunction but can also be the result of different coffee-bed 
preparations. Redo the check with blind-filters on a cold machine with all heat circuits turned OFF (on 
a heated machine entering cold water heats up and expands, leading to pressure increase that is not 
related to incoming pressure). Have a technician replace the gauges when the divergency persists. 

 

 

5

 When water mains pressure for the machine is always equal to or higher than your optimum pre-

infusion pressure, a pump will not be necessary. If at any time the water mains pressure is expected to 
fall below optimum pre-infusion pressure you should consider the installation of a pump and possibly 
also an expansion-tank.
