Installation
Steam connections (optional steam heating)
Steam pressure required:
• minimum 7 PSI
• maximum: 110 PSI

A steam valve for this machine type is fitted
separately in a bracket on the upper rear cover
plate. The steam valve, hose and filter are sup-
plied with the machine.
Steam-flush all pipes and hoses before connec-
tion.
Installation instructions:
• Install rear cover plates.
• Install steam valve bracket and valve. The
steam valve must be mounted in upright
position.
• Connect the steam hose between the steam
valve and the steam intake on the machine.
• The steam inlet pipe must be fitted with a
manual cut-off valve. Fit the filter supplied with
the machine to the manual cut-off valve.
• Connect an approved 1/2'' steam hose be-
tween the steam valve and the filter. The
connection must be vertical or be fitted with a
pipe connector in order to avoid sharp angles
in the hose.
• Connection size at filter: DN15 (R 1/2''').
Check that there are no sharp angles or
bends in the connection hose.
