WATER QUALITY
As with all steam related products, water filtration and
regular filter replacements may be necessary with the
Combi. It is strongly recommended to have a water
analysis performed prior to installing the Combi. Poor
water quality can have a big impact on cook quality,
performance, and longevity of the Combi. Varying
combinations of pH; alkalinity; hardness; chlorides; total
dissolved solids; and other chemical characteristics,
when subjected to high temperatures, will cause water
to have a tendency to either scale or corrode.
There are a number of different water filter/treatment
systems available and each has its own benefits and
specialties. Below are a different styles and their
benefits. Multiple styles may need to be used to get the
water to proper levels.
• Particle Filter
When the water contains sand, iron particles, or
suspended matter, we recommend a 5-15 μm
(micrometer) particle filter.
• Active Carbon Filter
When the level of chlorine (Cl2) in the water exceeds
0.5 mg/L (ppm) (information available from the water
company), an active carbon filter should be installed.
• Phosphate Additive System
A Phosphate Additive (Feeder) System is recommended
for steam generator units only when a moderate level
of scale (not containing chloride) is experienced. The
system recommended is Kleensteam from Everpure.
• Ion Exchange System
An ion exchange system is recommended for a steam
generator based unit when a high level of scale (not
containing chloride) is experienced and for a spritzer
based unit when any scale (not
containing chloride) is experienced. Systems
recommended: Claris from Everpure (H+ Ion
Exchanger). Sodium ion exchangers (as used in
dishwashers) must not be used.
• Blended Reverse Osmosis (RO)
When the water has a chloride Cl- concentration above
20 mg/L (= 20 ppm), a blended RO system should be
installed to avoid corrosion.
Note: Make sure a minimum conductivity of 20 μS/
cm (microSiemens) remains in the water for steam
generator units.
Water quality must conform to the below requirements.
If water does not meet the minimum quality and
damage to the oven is determined to be due to water
quality, it will be considered non-warranty and will not
be covered under the stated warranty policy.
