Installation
DANGER
Risk of injury due to system toppling over.
The system must be installed on an even
and hard surface. In order to prevent the
system from sliding on floors with a gradi-
ent, the upgrade kit for floor fixation (order
no. 2.638-320.0) can be used.
– The system should only be set-up in a
dry, non-explosive environment.
– The system should be installed to be
easily accessible for maintenance
work. Using the 140 mm support legs
facilitates the maintenance process.
– The room temperature at the installa-
tion site should not exceed 40 °C.
– A water drain must be present at instal-
lation site.
Assembly
ATTENTION
Always keep the installation site of the sys-
tem well ventilated to protect the machine
against over-heating.
– The appliance should not be directly at-
tached to the network of water and high
pressure pipes. It is mandatory to install
the connecting hoses.
– A shut-off tap must be installed be-
tween the main water supply and the
connecting hose.
