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.
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.
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.
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).
