Mounting with Keyholes
1.
The NHRS Series humidifier is wall mounted using keyholes located on the back of the
unit cabinetry.
2.
Use #12 x 3” (7.5 cm) screws mounted into 2x4” studs or better. Two screws are
required for units with one tank (NHRS 10 to NHRS 90 lb/hr). Three screws are required
for units with two tanks (NHRS 135 and 180 lb/hr).
3.
Keyholes are spaced 16” (40.6 cm) apart center to center as per UL certification
standard stud spacing dictates. Insert screws into the studs until there is ¼” (0.6 cm) of
screw exposed. Ensure the screws are level to each other.
4.
Raise the unit and place the screws through the keyholes. Make sure the unit is level
before tightening the screws to secure the unit in place.
5.
Place L-shaped brackets on top of the unit, ensuring the holes are in-line with the studs.
Using the appropriate sized wood screw, fasten the L-brackets to the studs, securing the
unit from any upwards motion. See Figure 6.

Note: Use screws longer than 3” (7.5 cm) if drywall or other spacer is present.
