DRAIN CONNECTIONS
The drain connection must be 1" (25 mm)
IPS down, preferably with one or two
elbows only, maximum length 6 feet (1830
mm) and piped to an open gap type drain
(Figure 1). Drain pipe to be copper only.
DO NOT use PVC pipe – PVC pipe may
lose its rigidity or glue may fail.
CAUTION: To avoid
injury or damage to the
steamer, do not connect
solidly to any drain
connection.
WATER QUALITY
The water supply connected to the steam generator should meet the following guidelines:
Failure to comply with water quality statement on page 4 may void the warranty.
Water supplies vary from one location to another. Other factors affecting steam generation are
iron content, chlorides, and dissolved gasses. A local water treatment specialist should be
consulted before installing any steam generating equipment.
Untreated water contains scale producing minerals which can precipitate onto the surfaces in
the boiler. Due to the temperatures in the boiler, the minerals can bake onto the surfaces and
components. This can result in early component failure and reduced product life.
Mineral scale on components causes several problems:
1. The surfaces of the heating devices become coated with scale, reducing the heat transfer
efficiency. This can produce hot spots on the heating elements and result in premature
failure.
