LOCATION & MOUNTING

HUMIDIFIERS

NHSC / NHDI Series humidifiers are designed to

mount on a suitable wall or vertical surface. Do not sit
the unit on floor due to clearances required for
plumbing, electrical, and control entrances. The
clearance dimensions shown in this manual are for
reference only and are the minimum required for
maintenance of the humidifier. Local and National
Codes should be consulted prior to final location and
installation of the humidifier. NORTEC will not accept
responsibility for installation code violations.

1.

Location of the humidifier should be below and
as close as possible to the steam distributor
location. If possible, DO NOT locate humidifier
any further than absolutely necessary from
steam distributor location, as controllability
and net output will be reduced as a result of
heat loss through the steam hose (see Steam
Distribution Engineering Manual).

2.

Where possible, mount humidifier at a height
convenient for servicing.

3.

Wall mounting bracket provided should be
securely attached horizontally and open edge
facing upwards, using field-supplied fasteners.
For a single unit, use a minimum of 4 - #12 x
3” long wood screws. For a double unit, use a
minimum of 6 - #12 x 3” long wood screws.
These screws must be fastened securely on a
2 x 4 wood stud or equivalent support. If any
spacer material is used between the bracket
and the structural material such as drywall,
increase fastener length accordingly. In
addition, install a minimum of 2 field supplied
fasteners in the holes provided in the back of
the unit to prevent the unit from being bumped
off the wall bracket. See Figure #4.

4.

Mount unit on hanging bracket after ensuring
the bracket is properly anchored to the wall.
Raise the unit and place it on the hanging
bracket ensuring that the flanges in the
mounting bracket are properly aligned and
centered with the flanges of the unit. Push the
unit in towards the wall to properly interlock
the two flanges. Note: This will result in the
unit shifting slightly down. Ensure that the
hanging bracket’s flanges are fully engaged
