PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY
AND PLUMBING CODES.
Water Supply Connections
The water filter system, provided, must be installed in the water supply line going to the treated water
inlet of your steamer or the 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.
Water pressure to the steamer should be 20 to 60 psig.
The two incoming cold water supply connections at the rear of the steamer cabinet (Fig. 1) require

tubing (10 mm). Water supply to the boiler must be provided with a backflow preventer device to comply
with the Basic Plumbing Code of the Building Officials and Code Administrators International, Inc.
(BOCA) and the Food Service Sanitation Manual of the Food and Drug Administration (FDA). Supply
normal tap water to the condensing cold water connection at the rear of the steamer. This water supply
condenses steam prior to discharge into the open drain.
Water Requirements
Proper water quality to the boiler can improve the taste of the food prepared in the steamer, reduce
liming in the steam generator and extend equipment life. Local water conditions vary from one location
to another. Ask your municipal water supplier for details about your local water supply prior to
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 included with the
water filter.
DRAIN CONNECTION
Temperatures in the boiler can briefly reach as high as 212°F (100°C). Local codes will require that
the temperature of the drain water be 140°F (60°C) or lower. At the end of the day when purging the
boilers, some provision for lowering the water temperature must be provided by the user or installer to
meet this code requirement.
The steamer drain requires 2" IPS (51 mm) {1
1
/4" NPS} (Fig. 1), and should be piped to an open floor
drain near the steamer. To avoid back pressure in the drain, there should not be a solid drain
connection.
An open gap between the steamer and the floor drain is required. Maximum length of drain
is 6' (183 cm),
minimum length is 24" (610 mm). There should be no bends or elbows in the drain line.
