Important installation information – Table units
Water Feed (pic. 1)
• Connect to cold water, only drinking water quality.
• Safety combination (non-return valve) integrated as standard.
• Connection: 1/2" pressure hose with R 3/4" screwed
fitting.
• Customer-fitted water shut-off valve for each appliance.
• Water pressure: 150 to 600 kPa
recommended pressure: 300 kPa
• Observe standards of local water board.
• Optional Treated Water Connection (WZ 2)
(see Installation diagramm) with 2 water supplies:
1. "Normal water" for quenching system and steam
generator flushing system
2. "Treated water" for steam generator, moistening
and hand shower
Theoretical water consumption of the steam generator:
CCD 61: 0,2 l/min CCD 101: 0,42 l/min
CCD 102: 0,69 l/min
Water Drain (pic. 2)
• Use steam temperature resistant pipe - do not use a
hose!
•
A direct drain is possible since:
a ventilated gap is an integrated part of the appliance.
• Use DN 50 pipe with constant slope (min. 5% or
3°).
• Take drain dimensions into account: short-time
pump-out quantity of steam generator 0.7 l/sec.
• Waste water temperature approx. 65 °C.
Ventilation
For operation of the appliance a ventilation hood is not necessary.
If a ventilation hood is to be installed:
• The hood should protrude 300 mm to 500 mm over the front of the
appliance.
• The grease filter should be in the protruding part of the hood.

Rational recommends to install the following
components into the drinking water supply line
(see picture):
• A particle filter (0,08mm) with excessive soiling
of the supply water;
• A pressure regulator with 300kPa (3 bar) secondary side setting
with line pressure peaks of above 600kPa (6 bar);
• An active carbon filter with a clorine concentration of more than
30mgr/liter;
