Installation Guide

To install parallel to joist, attach the angle supports to the middle holes in the housing with the #8 x 1/2" screws provided. If distance between joists
is less than 14.5", top mounting holes must be used. Using the hole spacing guide in FIGURE 4, attach the joist brackets in a parallel manner so the
bracket edges are approximately 15 inches apart, as shown in FIGURE 2, with the #8 x 1" screws provided. After the joist brackets are secured, lift the
humidifier so the angle supports rest inside the brackets, as shown in FIGURE 4. After the humidifier is hung, check levelness of the unit and shim the
joist brackets as necessary.
If this is a finished ceiling, or you wish to install humidifier perpendicular to the joists, attach the angle supports to the top holes in the housing.
Attach the joist brackets in a parallel manner, so that bracket edges are approximately 15 inches apart, as shown in FIGURE 3, with the #8 x 1" screws
provided. After the joist brackets are secured, lift the humidifier so the angel supports rest inside the brackets.
