Notes:
• Pitch header towards drain 1/8" per
foot (1%).
• Position L-bracket so the flange is
Noninsulated
upstream of dispersion tubes.
• Use L-bracket as a template to locate
holes on duct wall.

DRISTEEM HUMIDIFIER DISPERSION

Before you begin installation, read all dispersion instructions.

• Unpack shipment and verify receipt of all Rapid-sorb
packing list. Report any shortages to the DriSteem factory immediately.
• When choosing a location for installation, select one that provides
necessary access in and around ductwork or air handler.
• Rapid-sorb assemblies are typically installed centered side to side in duct,
or across face of coil in air handler.
• The center line of the outer dispersion tubes should never be closer than
4.5" (114 mm) from side of ductwork or air handler wall.
• Rapid-sorb tubes are provided with an L-bracket for installation:
- NOTE: Before marking and drilling holes in duct or air handler,
refer to ALL pitch requirements for the Rapid-sorb assembly in
the instructions. Size, quantity, and location of penetrations are
determined by specific dimensions and configuration of Rapid-sorb
assembly you received.
NOTE: Hardware for mounting L-bracket to duct or air handler wall and
hardware for header support bracket is not provided. Use a fastener
of sufficient length on the L-bracket to accommodate 1/8"/ft (1%) pitch
requirements toward the 3/4" pipe thread (DN20) header drain fitting.
• Condensate drain connections to the Rapid-sorb header:
- Piping must be minimum 3/4" I.D. (DN20) and rated for 212°F
(100°C) minimum continuous operating temperature.
- Condensate drain line must be piped as shown in the figure. Provide a
2" (50 mm) drop prior to a 5" (127 mm) water seal.
• If multiple humidifiers are supplying one Rapid-sorb, a multiple steam supply
connector is needed:
- Typically, the multiple steam supply connector attaches to the Rapid-
sorb header supply end with hose cuff and clamps.
- Route the necessary number of steam supplies from the humidifier tanks
to the steam supply connector.
- Position the steam supply connector to accept the steam supplies while
maintaining the necessary pitch.
- Make sure the hose clamps on the steam supply connector and header
are tight.

If active tube length is <22" (559 mm), tube
quantity per panel may need to increase to
compensate for reduced capacity of short
tubes. Consult DriSteem or see DriCalc for
the correct calculation.
