2. For front and side clearance requirements (for
access during installation, maintenance and
troubleshooting), see Figure #2.
3.
Location
of
the steam distributor should be
minimum
of
36" above the humidifier.
4.
DO NOT locate humidifier any further than
absolutely necessary from steam distributor
location. Net output will
be
reduced as a result
of
heat loss through steam hose (see
Engineering Manual, Form # -1630). Also,
increased static pressure (over
7"
W.
C.) will
result
in
steam leaking down the drain.
Consult factory if this situation occurs.
5.
Where possible, mount humidifier at a height
convenient for servicing.
6.
Wall mounting brackets (provided with GH
100) should
be
securely attached open edge
upwards, horizontal, using field-supplied
fasteners (minimum offour
3/8"
diameter
fasteners
in
each bracket). Attach
to
a
vertical, solid surface. Put a security bolt
through the hole provided
in
the back of the
cabinet so that the unit cannot
be
bumped off
the wall bracket. See Figure #3.
