Setting Steam Pressure
There have been a few different pressure stats in the Andreja
through the years. They can all be found attached to a copper
pipe coming out the back of the boiler as shown in the picture
to the right.
To adjust the pressure stat, unplug the machine from the
outlet and then remove the outer shell.
Locate the pressure stat in your machine using the picture
below to identify which pressure stat you have.
Use a flat blade screwdriver to turn the center adjustment screw. Do not turn more than
1/8 of a turn at one time. The picture below shows the adjustment screw for each
pressure stat and the direction to turn to increase the pressure.
After adjusting the pressure then plug the machine back in and turn it on and allow it to
get up to pressure. If you need to make another adjustment then unplug the machine
again to make an adjustment. Repeat these steps until the desired pressure level is
achieved.
The recommended pressure setting is to have the green ready light to come on around
1.2-1.3 bar. This should cause the heater to come back on around 1 bar and then cycle
back and forth between these levels to maintain boiler steam pressure.
After setting the pressure unplug the machine from the outlet before putting the outer
shell back on.
WARNING - Do not set the pressure
above 1.5 bar or damage may occur.
Only adjust the center screw shown.
There is a small off center screw that
is covered with sealant. DO NOT
adjust this screw or it will damage the
pressure stat which is not covered
under warranty.
