If your order covers more than one
unit, separate each complete unit.
Humidifier tagging and manifold
tagging will be the same as shown on
the packing list. Model, Serial Number,
Steam Pressure, Orifice and Orifice
Restriction (if any) are on the metal
plate on the humidifier body. Operator
for electric motor operated unit is
shipped separately but marked with
the serial number of the humidifier
with which it must be used. Be sure
serial numbers agree.
STEP 2: Spot Humidifier Locations.
Locate each humidifier according to
the engineer's layout or as indicated
by your Armstrong Representative. If
you must locate the humidifiers
yourself, be sure to read and observe
the "Do's and Don'ts" on the following
page.

Manifold Installation
STEP 3: Cut Hole in Duct or Plenum
for Manifold. Use manifold
dimensions "X" and "Y" from Table 2-
2, below, and add approximately
for manifold clearance. If multiple
manifolds are used, read page 9 first.
STEP 4: Insert Manifold in Duct.
Outlet holes must point upstream into
air flow, except on insulated
manifolds point discharge holes
downstream. Where manifold is
positioned horizontally, use a spirit
level. Manifolds longer than one foot
should be supported. Put the two
piece manifold escutcheon plate in
position. When supporting the
manifold on the far end allow for
manifold expansion and contraction of
1/2" - 1".
