HUMIDIfIeR loCaTIon
Do not mount humidifier in a location where ambient
temperature exceeds 104°f or where freezing temperatures
may occur.
Extreme temperatures may cause the humidifier to leak
which can damage furnishings or structure .
Mount humidifier in a location that allows access for servicing, and
clearance to remove front panel for replacing the canister and side
panel for access to the electrical components during installation .
See
figure 12
for minimum clearances around humidifier .
The humidifier should be mounted as close to the dispersion
tube as possible .
Table 4
shows how capacity is reduced as the
distance between the humidifier and dispersion tube increases . If
the humidifier is mounted on the duct directly below the dispersion
tube, allow space for a bend in the steam hose . Allow a minimum
of 2” of steam hose to extend straight out of the humidifier before
beginning any bends; this will help ensure a tight connection with
the top of the canister .
The humidifier can be mounted to a wood surface, or to sheet metal
ductwork if it is structurally stable . Do not mount humidifier to fiber
duct board . Sound isolation may be desired when mounting to sheet
metal ductwork .
The humidifier must be mounted to a vertical surface and must be
mounted level in the upright position .
