LOCATION & MOUNTING

HUMIDIFIERS

NH Series humidifiers are designed to mount on a suitable wall or vertical surface. Do not sit 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 can 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
	as possible.
2.	For front and side clearance requirements (for
	access during installation, maintenance and
	troubleshooting), see Figure #2.
3.	If possible, DO NOT locate humidifier any further
	than absolutely necessary from steam distributor
	location, as net output will be reduced as a result
	of heat loss through steam hose (see Engineering
	Manual, Form -163D). Also, increased static
	pressure may necessitate using an accessory fill
	cup extension kit.
4.	Where possible, mount humidifier at a height
	convenient for servicing.
5.	Wall mounting bracket provided should be
	securely attached horizontally and open edge
	upwards, using field-supplied fasteners. Use a
	minimum of 3 - #12 x 3" long wood screws, or

better, into a vertical structural surface. 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 #3.

6.Make sure humidifier is level.

7.DO NOT mount humidifier on hot surfaces.

8.If humidifiers are mounted on roof, a thermostatically ventilated weatherproof cabinet by others should be used. Consult factory.

9.DO NOT mount humidifiers in an area where freezing may occur. Use an accessory Low Temperature Protection Kit, if necessary.

10.DO NOT mount humidifiers on vibrating surface. Consult factory.

BLOWER PACKS

1.Blower packs are an optional accessory used to directly distribute steam to localized areas (such as computer rooms) or in structures that do not have a built-in air distribution system.

2.Blower packs are available integrally-mounted on humidifier (built-on blower pack, BOBP, see Figure #4) or detached and field-piped and wired to humidifier (remote mounted blower pack RMBP, see Figure #5).
