Mount fan Pack Housing
The Fan Pack installs between the studs of a standard 16” on-center
wall . Drywall on both sides of the wall must be removed for piping
and wiring the Fan Pack . To ensure proper operation, the Fan Pack
must be mounted level . Use the four 1-1/2” mounting screws
provided to attach the housing to the wall studs . See
figure 6
.
Grille Installation
Use the two 5/8” screws to attach the Fan Pack grille to the fan
housing and drywall . See
figure 6
. If painting the grille is desired,
see a painting professional for acceptable paint products for high
temperature (212°F), high humidity environments .
fan Pack Hose Connections
Connect the steam hose to the Fan Pack and use hose clamp to
secure . See
figure 7
. If more than 6 feet is required, use insulated
hard pipe as shown in
figure 11
. See Specifications & Dimensions
(page 5) for the affect on capacity . Ensure the trap is filled with water
before making steam connections .
Connect 3/8” ID condensate tubing to the Fan Pack and use wire-
tie to secure See
figure 7
. To create a trap, make a 6” loop in the
condensate hose . See
figure 4
.
noTe:
The 6” loop must be located
below the Fan Pack connection . Do not kink the condensate hose . Use
wire ties to secure the loop . The loop is required to prevent steam
from escaping into the drain .

The preferred location for the dispersion tube/fan pack is higher than
the humidifier so that the steam hose has a constant downward
slope of at least 2” per foot from the dispersion tube/fan pack to the
humidifier . If hard pipe is used, the slope can be 1/4” per foot . With the
constant downward slope, any condensation that forms in the steam
hose will drain back into the steam canister . See
figure 8
.
