1.3. WATER CONNECTION
ATTENTION:
Property damage
The use of old hose sets for connection to the water supply
facility can cause water damage.
The included connection hose must be used for connection to
the water supply facility.
Old hose sets cannot be reused.
Connect to warm water, if possible (max. 60°C).
– Water hardness:
• Machines without softener: max. 3.75° Clark = 0.5 mmol/l.
• Machines with softener: max. 37.5° Clark = 5.3 mmol/l.
– Line ow pressure
• with integrated rinse pressure pump:
Line ow pressure 0,8 – 6 bar.
> 6 bar: pressure reducer valve necessary.
• without integrated rinse pressure pump:
Line ow pressure: 3 – 6 bar.
< 3 bar: provide a rinse pump at site.
> 6 bar: pressure reducing valve necessary.
– Connect the union nut “A” (3/4”) of the water supply hose to the
site shut off valve.
– Do not kink or cut the supply hose. If an extended supply hose is
required, use one of the same specications as the original.
NOTE: The machine must be operated with potable water. For water
with an extremely high mineral content an external deminer-
alisation is strongly recommended
1.4. DRAIN CONNECTION
Machine without drain pump
– Ensure gravity drain.
– For these machine types, a oor drain is mandatory as the drain
hose exits the machine at approx. 60 mm above oor level. Other-
wise, residual water may remain in the tank and hose.
– Do not kink drain hose.
Machine with drain pump
– Connection between machine and site drain must not exceed max.
height of 0,65 m.
– Do not place the drain hose loosely on the oor (the hose could be
rubbed through). Fix it at site!
– Do not kink drain hose!
