MANUAL 1195730 REV0 (11/22/2011) 7 HEAVY DUTY STEAM
PLUMBING CONNECTIONS
WARNING: Plumbing connections must comply with applicable
sanitary, safety and plumbing codes.
Connect the water supply line to the 3/8" NPT (internal thread) copper tube inlet. The 3/8"
water line supplies water to both the generator tank and the cooling system where steam is
condensed before entering the drain line. Should your unit have the optional split water lines,
each will be marked to indicate condensate or boiler feed. The condensate feed must be cold
water and the boiler feed may be either cold or hot water. Providing hot water feed to the
generator will reduce recovery time during cooking. A manual shutoff valve must be provided
convenient to the steamer.
DRAIN CONNECTIONS (FIGURE 2)
The drain connection (Fig. 2) must be 1" IPS down, preferably with one elbow only, maximum
length of 2 feet before open air gap and piped to an open air gap type drain. Drain pipe should
be copper. DO NOT use PVC pipe - PVC pipe may lose its rigidity or glue may fail.
FIGURE 2
CAUTION: In order to avoid any back pressure in the steamer, do
not connect solidly to any drain connection.
