3.4.2 Duct Distribution (Additional kit required)
If a duct steam distribution nozzle is to be used, select an accessible location on the duct, allowing at least 36" of straight duct (no
elbows or obstructions) after the point where the nozzle will be installed and the clearances can be maintained as per the following
drawings. See Fig.3.j To mount the steam nozzle, cut or drill a 2-1/2" hole in the duct. Apply caulk to the mounting plate of the
nozzle. Attach the nozzle to the duct using 4 #10 sheet metal screws (supplied). Nozzle must be level or vertical with condensate
outlet to the bottom.
IMPORTANT: Allow 1 M (3 feet ) of straight duct downstream of the distributor pipes and nozzles for absorption of the steam.
Always allow 0.6M (2 feet) of straight duct upstream of the distributor pipes for evaporation of the steam. Turbulent air flow may
.
require longer lengths
To Install The Distributor Pipes:
1. Cut a round hole in the side of the duct to match the steam pipe and condensate return.
2. Apply silicone sealant to the mounting plate and insert the pipe through the hole and secure it with
sheet metal screws. See Fig. 3.k
3. Connect the steam and condensate hoses using the hose clamps supplied.
(Note: end support bracket supplied only with 36" and longer distributors.)
3.4.3 Return Condensate Connection
The return condensate hose from the nozzle, etc. must be trapped. Coil the hose into a vertical loop
and secure it below the nozzle, etc. This trap prevents steam from being released into the cabinet.
The hose end may be run through the knockout at the top of the humidifier and be inserted into the
hole located on top of the fill cup. The hole may be enlarged to suit. See Fig.3.l.

IMPORTANT WARNING: NINETY PERCENT (90%) OF ALL OPERATION PROBLEMS ARE CREATED BY IMPROPER STEAM
PIPING FROM THE HUMIDIFIER UNIT TO THE DUCT DISTRIBUTOR PIPES.
To avoid these problems, remember one simple fact when running the steam hose: steam naturally flows up hill, and condensate
naturally flows downhill. Run the steam hose or piping to avoid any kinks, sharp elbows, or low spots that could collect or restrict the
flow of steam to the distributor pipe, or the flow of condensate back to the humidifier. Support the hose adequately to avoid sags.
The following diagrams are to provide you with some guidelines. If you have a situation you are unsure of, please contact the factory
for instructions.
