The following guidelines are for a 240V installation in which the unit
discharges into a space with 70°F air temperature and 40% RH .
• Allow 5 feet of unobstructed space directly in front of the grille .
• Allow 2 feet on either side of the grille .
• Allow 1-1/2 feet above the grille .
See FIGURE 7 .
If the room temperature is less that 70°F, allow an additional 6" to each
distance for every two degree drop in temperature .
If the RH set point is higher than 45%, allow an additional foot of space
between the grille and any obstruction or surface .
Warmer room air temperature and RH below 35% will reduce the
amount of unobstructed space required to absorb discharged steam,
but the distances provided are recommended minimums .
DISTANCE FROM HUMIDIFIER TO FAN PACK
The capacity of the humidifier is reduced by the length of the steam
hose or pipe due to condensation . The maximum recommended length
of steam hose is 6 feet . Use hard pipe insulated with 1" thick insulation
rated for 212°F or higher for lengths greater than 6 feet . If 6-foot steam
hose does not reach from humidifier to dispersion tube, splice in 1"
copper pipe using 3/4" x 1" reducing couplings as shown in FIGURE 6 .
MOUNT HOUSING
The Fan Pack installs between the studs of a standard 16" on-center
internal wall . 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 8 .
