4. Locate where you will install
the duct steam nozzle in the duct
(if used), and then decide on a
convenient location for the
humidifier, that will permit the
hoses to be sloped properly.
5. Use the mounting bracket to
mark the wall for drilling. Use a
level to insure the unit will hang
level. (See Figure 4 at right)
CAUTION:
make sure that the
screws will go into wall studs to
support the weight of the
humidifier.
6. If the mounting screws will be
screwed into wood, drill 2 -1/8"
pilot holes for the mounting
bracket. If dry wall, drill 2 -5/16"
holes for the anchors.
(See Figure 5 above)
7. Insert the screw anchors if
needed and then screw in the
mounting screws through the
bracket. The top edge of the
bracket should stand out away
from the wall.
(See Figure 6 above)

Mount the humidifier unit as close
to the steam distributor pipe as
possible to minimize condensate.
Mount the humidifier unit below
the steam distributor pipe
whenever possible. Insure that a
slope can be maintained in the
steam hoses. Certain mounting
clearances must be maintained to
allow access for maintenance, and
for steam discharge from the
blower unit:

and cap off the condensate
outlet nipple.
12. Cut or drill a 2-1/2" hole in the
side of the duct to fit the steam
nozzle.
13. Apply silicone caulk to the
faceplate of the steam nozzle and
insert it into the duct with the 5/16"
outlet nipple at the bottom, as
shown in Figure 12 above.
14. Attach the steam nozzle to the
duct using #10 by 1/2" drill point

CAUTION:
90% of all
operational problems with the
MiniSteam humidifier can be
traced to improper installation of
the steam hose. It is very critical
that steam be allowed to flow
freely from the humidifier unit to
the steam nozzle, and that
condensate can flow back.
■A 20% slope must be
maintained from the humidifier
unit to the steam nozzle. That
means the hose must slope up
2 1/2" for every foot of the
length of the steam hose.
■There must be NO sags,
kinks or low areas in the steam
hose that can collect
condensate or otherwise
restrict the steam flow.
■Copper tubing may be used
in place of the steam hose, but
it must be a minimum of 7/8"
ID and must be insulated.
DO NOT REDUCE THE SIZE
OF THE STEAM HOSE OR
PIPE.
16. Slip the end of the 7/8" ID
rubber steam hose over steam
nozzle inlet nipple and secure it
with the stainless steel hose clamp
supplied.
(See Figure 15 at right)
17. Slip the 5/16" ID condensate
hose over the steam nozzle
condensate outlet nipple and
secure it with the plastic hose
clamp supplied.

18. Bring the end of the steam
hose through the hole in the top of
the humidifier cabinet and slip the
end over the steam cylinder outlet.
Secure the hose using the stainless
the steel hose clamp supplied.
(See Figure 17 at right)
18. Reinstall the steam cylinder
into the humidifier unit by pressing
it down into the O-ring fitting at
the bottom, and then securing all
wires.
CAUTION:
Loose electrical
connections could cause fire, so
make sure all fittings are tight.
(See Figure 18 above)
20. Bring the end of the
condensate hose through the
smaller hole in the top of the
humidifier cabinet and cut it so it
ends in the drain pan of the
humidifier.
