WATER QUALITY REQUIREMENTS
Contact a local water treatment specialist for an on-the-premises water analysis.
The recommended minimum feed water quality requirements for the Oven/Steamer are
listed in Table 2-2.
Table 2-2. Minimum Supply Water Quality Requirements
Total Dissolved Solids less than 60 parts per million
Silica less than 13 parts per million
Alkalinity less than 0 parts per million
Chloride less than 30 parts per million
pH factor greater than 7.5
Softened, Treated, or Filtered Water
Do not use softened or chlorinated water in the steam generator.
If the water supply is treated or softened either by the water company or on the
premises, it may contain chlorine or various salts.
These additives are damaging to the steam generator. Salts used to soften water cause
rapid scale buildup, and increased corrosion.
The hardness of the water has to be from 1 ÷ 4 degrees Clark (1 to 6 fH/0.5 and 2.8
dH). Some water treatment plants kill bacteria in the water by adding chlorine.
When heated in the steam generator, chlorinated water rapidly dissolves generator walls
and heater elements. In extreme cases, poisonous and highly corrosive chlorine gas is
released in the steam generator. Installing a high volume water filtering system removes
most of the salts used for water softening. Contact a local water treatment specialist or
the local water company for assistance with chlorinated water.
Always connect an untreated cold water supply to the steam quenching and boiler
rinsing water supply line. DO NOT USE HOT WATER.
The oven/steamer will not function properly or within design safety limits if hot or
warm water is supplied.
