3. Install Water Supply
a. Install the water supply before positioning the Combi.
b. Water supply line(s) must be designed so the Combi can be moved for service.
c. Construct all supply lines up to the point of installing the Combi.
d. Flush the water supply lines before connecting the Combi to the water supply lines.
e. Water Supply Requirements
1) Water Quality
a. Check the quality of supply water (described below) before designing the water supply.
b. Contact a local water treatment specialist for on-premises water analysis.
c. Minimum feed water quality requirements are listed in Table 2-3.
d. Poor water supply quality degrades Combi performance.
e. Softened or chlorinated water damages the steam generator by increasing
corrosion. Carbon type filters are required before water enters the steam generator
if supply water is softened or chlorinated.
f. If a water treatment system must be installed to achieve acceptable water quality,
install it
BEFORE connecting the water supply lines to a Combi.
g. If analysis shows that supply water is below Minimum Water Quality:
1) EITHER a water treatment system and/or carbon filter must be installed in the
line feeding the steam generator,
2) OR the frequency of maintenance, cleaning, and descaling must be increased
beyond that recommended in the maintenance schedule.
3) Contact your Cleveland Range sales representative for details on how to
provide water per Minimum Water Quality in Table 2-3, or how to increase the
frequency of maintenance, cleaning, and descaling.
Table 2-3 Minimum Water Quality Requirements
Scale Forming Factors Concentrations must be:
Total Dissolved Solids less than 60 parts per million
Silica less than 13 parts per million
Alkalinity less than 20 parts per million
Corrosion-Causing Factors Concentrations must be:
Free Chlorine less than 0.5 parts per million
Chloride less than 30 parts per million
pH factor greater than 7.5
CAUTION
Using water outside the limits specified in this manual
without appropriate adjustment in the maintenance
schedule voids warranty coverage.
