connected via vapor hose to a wall-mounted
CRUV humidifier.

Locate the CRUV humidifier near an electric power source, a water
supply, and a drain. Verify that sufficient 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 humidifier inside a packaged unit, provide
adequate support. Allow easy access for removing and servicing the
evaporating chamber, and provide adequate clearance to install the
vapor 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 vapor 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 vapor hose. This application is
not recommended for CRUV Models 10 through 34.
