Steam Distribution
Installation Requirements
1. Use steam line made of copper or stainless steel tube exclusively,
or use a Condair steam hose for short distances. Steam line made
of any other material may adversely affect the operation of the
humidifier, and will void the warranty. Refer to the table below for
steam line sizing.
2. To prevent excessive backpressure in the steam cylinder, the steam
line must not have any restrictions.
3. The steam line must run straight up from the humidifier minimum
12 in (300 mm) before any bends.
4. The steam line must have a constant slope – minimum upslope of
10°, or minimum downslope of 2°.
5. Do not merge steam lines, except at the steam distributor. Use a
Condair adaptor designed for the purpose.
6. Insulate the steam line with minimum 1 in (25 mm) pipe insulation.
7. Support the steam line so there is no load on the humidifier.
8. Install condensate lines at all low points and horizontal-to-vertical
transitions in the steam line. The condensate line should always
connect to a full size “Tee” connector, and have a minimum con-
stant downslope of 1.2°. The trap should be located minimum 12 in
(300 mm) below the connector, and have a minimum height of 8 in
(200 mm).
9. Use 3/8 in (9.5 mm) Condair condensate hose, or 1/4 in (6.5 mm)
Med-L copper tube or 3/8 in (9.5 mm) stainless steel tube for
condensate traps.
10. Install condensate traps every 15 ft (4.5 m) in the steam line.
11. Upon completion of installation, purge the steam and condensate
lines to remove any contaminants or construction material.
12. Prime the condensate traps with water.
Refer to “Steam Line Connections“ in the Installation Manual for other
details.

* Use a single steam line for each steam cylinder. Do not combine lines except at a
distributor, and only if using the steam cylinders in parallel.
Refer to the Installation Manual for over-sized steam lines for longer steam runs.
WARNING!
Risk of serious injury or damage to equipment!
Restrictions in the steam line can cause excess build-up
of backpressure which can result in serious burn injuries
or damage to equipment. Backpressure should not exceed
5.5 in H2O (1.36 kPa).
