CRUV INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Selecting a location
Horizontal mounting of dispersion tube in a duct,
connected via steam hose to a wall-mounted
CRUV humidifi er.
OM-2006
Duct
Steam hose
Locate the CRUV humidifi er near an electric power source, a water supply,
and a drain. Verify that suffi cient room is provided for a water seal in the drain
piping. See Figures 8-1 and 9-1.
Place the control cabinet or electrical subpanel in a grounded protective metal
enclosure, and mount in a dry and accessible location.
CRUV IN A PACKAGED UNIT
When installing a humidifi er inside a packaged unit, provide adequate
support. Allow easy access for removing and servicing the evaporating
chamber, and provide adequate clearance to install the steam hose and
dispersion tube and water seal.
DISPERSION IN A DUCT
When rapid absorption is extremely critical, a Rapid-sorb can provide 100%
steam absorption within three feet or less at any duct temperature. A multiple
tube or Rapid-sorb is required for CRUV Models 30 and 34 because of their
high output. See Figure 7-1 and the “Rapid-sorb” section beginning on Page
22.
When installing a dispersion tube in a duct, allow for a continuous pitch of the
steam hose back to the evaporating chamber (Figure 6-2), or use a water seal
and drain (Figure 7-1).
If draining the evaporating chamber by gravity is not possible, use a small
condensate pump rated for 212 °F/100 °C water.
The dispersion tube can be mounted vertically in the duct (Figure 7-2).
Note: When dispersion tube is more than 10' (3 m) from unit, insulated, 1½"
(38 mm) diameter minimum rigid tubing or pipe should be used instead
of steam hose. This application is not recommended for CRUV Models
10 through 34.
