PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY,
AND PLUMBING CODES.
Water Supply Connections
Two cold water supplies are recommended. Treated water may be required to fill the boiler; untreated
water may be used for the cold water condenser on the boiler blowdown line.
Connect cold water supply to the
1
2" NPT (1.27 cm) fill water connection. Water treatment may be
needed — refer to Water Quality, page 8. Water pressure of 20 – 80 psig is required.
Connect cold water supply to the
1
8" NPT (0.3175 cm) cold water condenser connection (treatment
is not needed). Water pressure of 20 – 80 psig is required.
Drain Connection
The 1
1
/4" NPT (3.175 cm) threaded fitting on the condenser box must be extended to an open, air gap
type drain, with maximum length of 12 inches
(30.5 cm) to the open drain. Do not reduce the 1
1
/4"
(3.175 cm) drain piping throughout its length. Provide a suitable floor sink with a minimum depth of 12
inches
(30.5 cm). The floor sink is NOT to be directly under the steamer and should be at a distance so
that steam vapors will not enter the steamer from underneath.
Drain pipe should be either iron or copper. DO NOT use PVC pipe — PVC pipe may lose its rigidity
or glue may fail.
CAUTION: In order to avoid any back pressure in the steamer, do not connect solidly to any
drain connection.
