PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY
AND PLUMBING CODES.
Water Supply Connections
The water filter, provided, must be installed in the water supply line going to the filtered water inlet or
your steamer warranty may be voided. For incoming water supply line pressures, refer to the water
filter manual shipped with the water filter. Follow the recommendations contained in it. Unfiltered water
should be connected to the condenser on the blow-down line. Water pressure to the steamer should
be 20 to 60 psi.
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. Local water contitions vary from one location to another.
Ask your municipal water supplier for details about your local water supply before installation.
Recommended water parameters are included in the water filter manual shipped with the steamer;
follow the recommendations contained in it.
Presence of sediment, silica, excess chlorides or other dissolved solids may lead to a recommendation
for alternate form(s) of water treatment. Be sure to test the water with the test strip and register the
results using the registration card or by visiting vulcanhart.com.
Filtered Water Connection — Used for boiler feed water.
Unfiltered Water Connection — Used as cold water condenser on boiler blow-down line.
Drain
CAUTION: In order to avoid any back pressure in the steamers, do not connect solidly to any
drain connection.
The drain must be the open air gap type. Provide a suitable floor sink with a minimum depth of
12" (
30 cm). The floor sink is NOT to be located directly under the steamer. Local codes require that
the maximum temperature of drain water must be no greater than 140°F (
60°C). Refer to Fig. 4 on
page 9. The drain pipe should be either iron or copper. DO NOT use PVC pipe; PVC pipe may lose
its rigidity or glue may fail.
