1. HUMIDIFIER INSTALLATION
A. LOCATION
(1) The NORTEC NHTC series humidifier is designed to mount on a suitable wall or
vertical surface. Do not sit the unit on the floor due to clearances required for
plumbing and electrical connections. The clearance dimensions shown in this
manual are for reference only and are the minimum required for maintenance on
the humidifier. Local and national codes should be consulted before final location
and installation of the humidifier. NORTEC cannot accept responsibility for
installation code violations. See Figure 1 Clearances and Operating Conditions.
(2) The location of the humidifier should be below the steam distributor. DO NOT
locate the humidifier any further then absolutely necessary from the steam
distributor location as net output will be reduced as a result of heat loss through the
steam line.
(3) When possible, mount the NHTC humidifier at a height convenient for servicing.
B. MOUNTING WITH KEYHOLES
(1) The NHTC series humidifier is wall mounted using keyholes located on the back of
the unit’s cabinetry. The keyholes are spaced 16 inches apart center to center for
large units and 10.7 inches apart for small as per UL certification standard stud
spacing dictates.
(2) Use #12 x 3 in. screws. 2 screws are needed for a single unit (NHTC 010 to 100
lbs/hour). 3 screws are needed for a double unit (NHTC 150 to 200 lbs/hour). Insert
the screw 16 in. apart. Be sure the screws are level to each other. Proceed to
insert the screws into the studs until there is 1/4 in. of screw exposed. Ensure the
screws are properly anchored to the wall.
(3) Raise the unit. Align the keyholes on the back of the unit with the screws. Place the
screws through the keyholes. Make sure the unit is level then tighten the screws to
secure the unit in place.
(4) Once the unit is securely fixed to the wall, install the “L” shaped brackets into the
same studs the unit is attached to. Place the brackets on top of the unit, inline with
the studs. Using the appropriate sized wood screw fasten the “L” brackets to the
studs securing the unit from any upward motion. See Figure 2 Mounting with
keyhole.
C. MOUNTING WITH WALL BRACKET
(1) For NHTC units that mount using a Wall mounting bracket 3 x #12 3.0 inch wood
screws are to be used.
(2) Wall mounting bracket provided should be securely attached horizontally with open
edge upwards, using field-supplied fasteners. Be sure the bracket is mounted level
See Figure 3.
(3) If humidifiers are mounted on a roof, a thermostatically ventilated weather proof
cabinet should be used. Consult factory.
