Mounting with Keyholes
1 The RH humidifier is wall mounted using a keyhole located on the back of the unit’s
cabinetry.
2 Use #8 x 2 in. (5 cm) screws mounted into 2x4 studs or better. 2 screws are needed, one for
hanging the unit and one for securing it so it will not lift off the keyhole.
3 Install the top screw so that 1/4 in. (6 mm) is exposed. Raise the unit and place the screw
head through the keyhole.
4 Make sure the unit is level and then insert and tighten the second screw through the bottom
hole. Tighten the top screw. See Figure 5: Mounting With Keyholes.

Note: Use screws longer than 2” (5 cm) if drywall or other spacer is present.
