Setting Steam Pressure
Warning:
This adjustment requires removing the shell and making an adjustment with the
machine plugged in so it is very important to exercise extreme caution. Failure to do so may
cause injury, and or electrical shock. Chris‟ Coffee Service and its distributors assume no
liability for failure to follow this warning.
It is only necessary to remove the top of the
machine to adjust the steam pressure.
Before making an adjustment the machine
should be up to temperature.
Remove the yellow cap that is covering the
pressure adjustment screw.
Using a flat blade screwdriver, turn the
adjustment screw clockwise to increase the
pressure, counter clockwise to decrease.
Only make a 1/4 turn adjustment at a time and then open the steam valve for 2-3 seconds
and then close it to get the heater to cycle on. You want to adjust the pressure stat so that
the heater light turns off at about 1.2-1.3 bar. When adjusted properly the heater should
come on at around 1 bar and then turn off around 1.3 bar.
You may have to repeat this procedure a few times to get the pressure set properly.
You may set the steam pressure lower if you desire, but you will not have as much steam
capacity and the recovery time will be longer. Recommended setting is 1.2-1.3 bar.
Warning: Do NOT set the steam pressure above 1.5 bar. Doing so may cause the
pressure relief valve on the boiler to open up and release the steam from the boiler. Any
damage caused for failure to follow this warning will not be covered under warranty.
