Failure to follow the recommendations in

this section can result in excessive back

pressures on the humidifier. This will result

in unacceptable humidification system

performance such as leaking gaskets, blown

water seals, erratic water level control, and

spitting condensate from the dispersion

tube(s).

Connecting humidifier to dispersion assembly with vapor hose

• Always support vapor hose to prevent sags or low spots and to

maintain a minimum pitch of 2"/ft (15%) back to the humidifier.

• See the maximum steam carrying capacity table on the next page.

• Use DRI-STEEM vapor hose. Other manufacturers of vapor

hose may use unacceptable release agents or material mixes

that can affect humidifier system performance adversely. Using

hose from alternative manufacturers increases the possibility of

tank foaming and accelerated aging. Foaming causes condensate

discharge at the dispersion assembly.

• Do not use vapor hose in outdoor applications.

• Do not insulate vapor hose. Insulation causes accelerated heat

aging, causing the vapor hose to become hard and susceptible to

failure due to cracks.

• The steam outlet on the humidifier is sized to the output of the

humidifier. DO NOT use hose with an inside diameter (ID)

smaller than the humidifier steam outlet.

• If the humidifier must be located above the dispersion assembly,

use the recommended installation as shown on Page 38.

• For single tube applications, see the hose kit sizing table on

Page 39.

Connecting humidifier to dispersion assembly

with tubing or pipe

• See the table on Page 40 for interconnecting tubing and pipe

pitch requirements for single tube and multiple tube applications.

See the table on Page 45 for interconnecting tubing and pipe

pitch requirements for Rapid-sorb applications.

• The steam outlet on the humidifier is sized to the output of the

humidifier. DO NOT use interconnecting tubing or pipe with an

inside diameter (ID) smaller than the humidifier steam outlet.

C A U T I O N ! Reducing the inside diameter of the

interconnecting piping will result in the internal humidifier

system pressure exceeding the parameters for acceptable

performance.

• Steam supply adapters are available from DRI-STEEM. These

adapters convert a tubing outlet on the humidifier to threaded

pipe, allowing a pipe connection.

• 90° elbows are not recommended; use two 45° elbows, 1' (0.3 m)

apart.

• Thin wall tubing heats up faster and causes less start-up loss than

heavy wall pipe.
