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. Local
water contitions 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.
A local water treatment specialist should be consulted before installation of steam generating
equipment.
Water Supply Connections
A water filter system is recommended for the water supply line going to the treated water inlet of your
steamer. Follow the recommendations for use and installation instructions shipped with the water filter.
If a water filter is not installed, the steamer or steam generator warranty may be limited.
Filtered Water Connection —
1
/4" NPT. Used for boiler feed water.
Unfiltered Water Connection —
1
/4" NPT. 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.
