Blower Packs

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. Liebert 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. Also, increased static pressure may
	cause operational problems and necessitate
	use of the fill cup extension kit and other
	components.
4.	Where possible, mount humidifier at a height
	convenient for servicing.

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.

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.

10.DO NOT mount humidifiers on vibrating surface.

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.

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.
