PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST
COMPLY WITH APPLICABLE SANITARY,
SAFETY AND PLUMBING CODES.
Water Requirements
Proper water quality can improve the taste of
the food prepared in the steamer, reduce liming
in the steam generator and extend equipment
life. Water conditions vary from one location to
another. Ask your municipal water supplier for
details about your local water supply prior to
installation. Presence of sediment, silica, excess
chlorides or other dissolved solids may lead to
a recommendation for alternate form(s) of water
treatment. Test the water with the test strip
included with the steamer. Other factors
affecting steam generation are iron content,
amount of chloridation and dissolved gases.
Water Treatment
A local water treatment specialist should be
consulted before installation of steam generating
equipment.
Supply Pressure 20 - 60 psig
Hardness* No more than 3 grains
Silica less than 13 ppm
Total Chlorine less than 4.0 ppm
PH range 6.5 - 8
Undissolved Solids less than 5 microns
*17.1 ppm = 1 grain of hardness
If the water supply fails to meet these standards,
it will be necessary to install a water conditioner on
the generator water feed. The use of strainers or
filters will not remove minerals from the water.
Water Supply Connection
Connect the treated cold water supply line to
the
3
/4" (19 mm) (male hose thread) inlet.
Connect the untreated cold water supply line to
the
3
/4" (19 mm) (male hose thread) inlet marked
UNTREATED WATER.
A water filter system is recommended for the
water supply line going to the treated water
inlet. Follow the recommendations for use and
installation instructions shipped with the water
filter. If a water filter is not installed, the steam
generator warranty may be limited.
A manual shutoff valve must be provided in a
convenient location near the steamer.
Filter System
If you decide to not install a scale-reducing filter
system designed for steam equipment or use
another manufacturer’s system other than that
recommended by Vulcan Hart, please use these
guidelines.
If you are going to delime the unit with a
deliming agent recommended for a
pressure steam boiler and stainless steel
generators, and you are on city or treated
well water, you still must have a carbon
block filter installed and maintained.
Carbon block filters remove the chlorine
and chloramine disinfectants from the
water. Chlorine and chloramines will
erode the boiler or steam generator and
will result in a vessel failure, which is not
covered under warranty.
Water feed lines to the steamer must be
flushed before final connection. Particles
in the water could build up in the water
and steam valves or clog tubing and
components that maintain the water level
and pressure in the boiler or steam
generator. If the water supply is not free of
sediment or is cloudy after several
minutes of flushing, a sediment filter must
be installed before use.
