Filter capacity:
Average treated water consumption is as follows
(values excluding usage of hand shower)
6x1/1 6x2/1 10x1/1 10x2/1 20x1/1 20x2/1
0,8 2,2 1,7 2,9 3,5 4,2
gal/h gal/h gal/h gal/h gal/h gal/h
Maximum flow rate 4,3 gal/min
Important for filter connection:
Water supply hose / pipe size 1/2” minimum
Connection to filter : 3/4”
Should a combination of filters be installed the
sequence A-B and C or D must be observed in flow
direction as shown in pic. 2 page 18.
Selection of water filter
C) Complete De-Ionization pic. 1/2
When the water has a chloride Cl- concentration
above 4.68 gr/gal (= 80 ppm), a complete
deionization system should be installed to avoid
corrosion.
Note: Make sure a remaining conductivity of 50
µS/cm (micro Siemens) remains in the water.
D) Water softener: pic. 1/2
Valid for SelfCookingCenter® 5Senses:
These models will remove scale all by itself pro-
viding that the units are used as prescribed. These
means a water softener is not needed.
Valid for Combi Master® Plus:
A water softener is recommended when a high
level of scale (not containing chloride) is experi-
enced (above 9.5 gr/gal) Systems recommended:
H+ Ion Exchanger or Kleensteam. Sodium ion
exchangers (as used in dishwashers) must not be
used.
As a phosphate dosing system can have negative
influence to the water system it must also not be
used.
Treated water with a water hardness less than 5
gr/gal must not be supplied, because such water
can react aggressive and corrosive which can
reduce the life cycle of the unit.
Amongst others the following filter manufacturers
offer adequate filter applications:
Brita (mavea), Cuno, Everpure,
Selecto-Scientific
Important for treated water connection:
Split the water supply to standard and treated water
connection for each unit to extend filter capacity!
Remove T-connection at water inlet
See pic. 1/2 on page 16
Connect cold untreated water to inlet position “2”
Connect treated water to inlet position “3”
