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 it's distributors assume no liabilty 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.
