10. Any distributor longer than 3 feet (1 meter)

should be supported at its end with a threaded
rod through top or bottom of duct. See Figure
#10.

11. It is recommended that single distributors are

mounted near the bottom of the duct to ensure
the steam is dispersed into the majority of the
air flow. See Figure #12.

12. Using duct mounting template provided, cut a

hole in side of duct just large enough to admit
steam manifold and condensate drain pipe
assembly. Use four sheet metal screws to
attach mounting plate to side of duct. See
Figure #11 and #12.

13. With multiple steam distributors, the top steam

distributor should be at least 8" below top of
duct to avoid possible condensation on
surface of duct. The remainder of space

below is proportioned accordingly. See Figure
#14. For short steam absorption systems see
Figure #13.

PLUMBING

All water supply and drain line connections

should be installed in accordance with local
plumbing codes.

WATER SUPPLY LINE

1.

Humidifier is intended to operate on potable
(cold) tap water.

2.

If the raw water is very hard, Liebert can
provide longer cylinder life on softened water.
However, softened water is more conductive
and more corrosive. Some hardware and/or
software changes may be required, at time of
order or in the field. Consult local
representative.

3.

DO NOT use a hot water supply to humidifier.
Minerals will adhere more easily to surfaces
and the fill valve’s small flow regulating orifice
could become plugged.

4.

Standard fill valves are sized for water
pressure ranging from 30 to 150 psig. For
other pressures, consult local representative.
This pressure should be measured at the
humidifier if the water pressure is suspect.
