Installation
Dispersion:
Rapid-sorb
Steam supply connections to Rapid-sorb header
Connect the steam supply interconnecting piping from the
humidifier to the Rapid-sorb. The steam supply piping requires a
minimum of 1/8"/ft (1%) pitch toward the header.
If multiple humidifiers are supplying one Rapid-sorb, a multiple
steam supply connector is provided. Typically, the multiple steam
supply connector attaches to the Rapid-sorb header supply end with
hose cuff and clamps:
1. Route the necessary number of steam supplies from the
humidifiers to the steam supply connector.
2. Position the steam supply connector to accept the steam supplies
while maintaining the necessary pitch.
3. Make sure the hose clamps on the steam supply connector and
header are tight.
Condensate drain connections to Rapid-sorb header
Piping must be minimum ¾" I.D. (DN20) and rated for 212 °F
(100 °C) minimum continuous operating temperature.
The condensate drain line must be piped as shown in Figures 8-1
and 9-1. Provide a 6" (152 mm) drop prior to a 5" (127 mm) water
seal to:
• Ensure drainage of condensate from the header
• Keep steam from blowing out of the drain line
After the water seal, run the drain line to an open drain with a 1"
(25 mm) vertical air gap.
• Cut the drain line at a 45° angle on the end above the drain
to permit a direct stream of water into the drain pipe while
maintaining a 1" (25 mm) air gap.
• Locate air gap only in spaces with adequate temperature and
air movement to absorb flash steam, or condensing on nearby
surfaces may occur.
All drain lines must be installed and sized according to governing
codes.
Ultra-sorb
For Ultra-sorb steam dispersion panel instructions, see the
installation, operation, and maintenance manual shipped with the
Ultra-sorb.

CAUTION
Operate Rapid-sorb within rated
steam capacity
Excessive steam flow to the Rapid-sorb
steam dispersion assembly can cause
condensate to exit the tubelets, which
can cause water damage and standing
water in the duct or air handler.
To avoid condensate exiting the tubelets,
do not operate the Rapid-sorb beyond its
rated capacity.
