VAPORSTREAM INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
INSTALLATION
The steam outlet on the humidifi er is sized to the output of the humidifi er. DO
NOT use steam hose or interconnecting tubing with an inside diameter smaller
than the humidifi er steam outlet. See note at right.
• See maximum steam carrying capacities in Table 38-1.
• If the humidifi er must be located higher than the dispersion assembly, use
the recommended installation shown in Figure 40-1.
CONNECTING TO HUMIDIFIER WITH STEAM HOSE
• Support steam hose to prevent sags, or low spots, and to maintain a
minimum pitch of 2"/ft (15%) back to the humidifi er.
• Use DriSteem steam hose. Other manufacturers of steam hose may use
unacceptable release agents or material mixes that can affect humidifi er
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 steam hose in outdoor applications.
• Do not insulate steam hose. Insulation causes accelerated heat aging,
causing the steam hose to become hard and susceptible to failure due to
cracks.
CONNECTING TO HUMIDIFIER WITH TUBING
• See Table 42-2 for interconnecting tubing pitch requirements for single tube
and multiple tube applications. See Table 47-1 for interconnecting tubing
pitch requirements for Rapid-sorb applications.
• Support interconnecting piping between the humidifi er steam outlet and the
dispersion system with pipe hangers. Failure to properly support the entire
steam piping weight may cause damage to the humidifi er tank and void the
warranty.
• 90° elbows are not recommended; use two 45° elbows, 1' (0.3 m) apart.
• Insulating tubing reduces the loss in output caused by condensation.

High-efficiency Tube option
Dispersion assemblies with the High-effi ciency
Tube option are designed to produce
signifi cantly less dispersion-generated
condensate and airstream heat gain, which
reduces wasted energy by up to 85%.
These improvements are accomplished by
reducing the thermal conductivity of the tubes
with 1/8" of polyvinylidene fl uoride (PVDF)
insulating material on the outside of the tubes.
These assemblies require careful unpacking,
installation, and handling. If your dispersion
assembly has the High-effi ciency Tube option,
be sure to read this section carefully.

Interconnecting piping requirements
Important:
Reducing the inside diameter of the
interconnecting piping will result in the internal
humidifi er system pressure exceeding the
parameters for acceptable performance.
