NOTICE
Using water outside the limits specified in this manual without appropriate
adjustment in the maintenance schedule voids warranty coverage.
2.4.2
Water Supply Requirements
2.4.2.1
Water Quality
1.
Check the quality of supply water (described below) before designing the water supply.
2.
Contact a local water treatment specialist for on-premises water analysis.
3.
Minimum feed water quality requirements are listed in Table 2-3.
4.
Poor water supply quality degrades MINI performance.
5.
Softened or chlorinated water damages the MINI by increasing corrosion. Filtration is
required before water enters the MINI if supply water is softened or chlorinated.
6.
If a water treatment system must be installed to achieve acceptable water quality, install it
BEFORE
connecting the water supply lines to a MINI.
7.
If analysis shows that supply water is below Minimum Water Quality:
EITHER
a water treatment system must be installed in the treated water inlet line feeding
the spritzer,
OR
the frequency of maintenance and cleaning must be increased beyond that
recommended in the maintenance schedule,
AND
Contact your Convotherm sales representative for details on how to provide water
per Minimum Water Quality Requirements in Table 2-3, or how to increase the frequency
of maintenance and cleaning.
2.4.2.2 Minimum Water Quality Requirements – Table 2-3
Scale Forming Factors
Concentrations must be:
Total Dissolved Solids
50-125 parts per million
Silica
less than 13 parts per million
Alkalinity
50-100 parts per million
Hardness
50-100 parts per million (3-6 gpg)
NH2CL(Monochloramine)
less than 0.2 parts per million
Corrosion-Causing
Factors
Concentrations must be:
Free Chlorine
less than 0.1 parts per million
Chloride
less than 25 parts per million
pH factor
between 7.0-8.5
2.4.3
Water Supply System Pressure Requirements
The water supply must provide:
A minimum dynamic pressure of 35 psi (2.4 kg/cm
2
)
A maximum static pressure of 80 psi (4.1 kg/cm
2
).
2.4.4
Connect Water Supply Lines
The Installer/Owner is responsible for the correct water connection of the MINI (see next page
for included kit parts and instructions). When connecting water supply lines observe the
following instructions, and all other applicable national, state, and local codes and regulations:
1.
Connect the MINI to COLD POTABLE WATER
