READ COMPLETE SAFETY INSTRUCTIONS AND INSTALLATION TEMPLATE BEFORE STARTING
TEMPLATE MUST BE LEVEL
1 Place unit on flat surface and pull
front cover up on right side. It snaps
loose. Remove evaporative assembly.
6 Reinstall the evaporative
assembly complete with the
evaporative media by fitting the drain
tube into the round receptacle at the
bottom of the unit. Push the assembly
in at the top against the beveled tabs.
Replace the front cover and attach
nameplate with appropriate brand
name.
9 Connect tubing from the saddle
valve to the inlet side of the solenoid
valve using 1/4" 0.D. copper tubing
(not furnished). DOUBLE WRENCH
TO PREVENT LEAKING!
2 The unit is assembled for left side
discharge. If right discharge is
necessary, remove the right and left
screws from the unit interior side
walls and exchange the two sides.
Reassemble with screws.

7 ~~ DISCONNECT ELECTRICAL
POWER TO FURNACE BEFORE
PROCEEDING. The Humidifier
Control is designed for low voltage
service to control humidification
equipment. An increase in relative
humidity expands the nylon ribbon
that opens the control switch to stop
operation on the humidifier. A
decrease in relative humidity
reverses the process and closes the
control switch. Install the Humidifier
Control.
TO INSTALL ON COPPER OR
PLASTIC PIPE
a) Place rubber gasket in center of
hole in top saddle clamp. Place
top and bottom saddle clamp
around water pipe. Using bolts,
tighten saddle clamps, evenly -
clamps should be parallel - DO
NOT over-tighten.
b) Screw valve body into opening in
top saddle clamp and tighten.
c) Tighten gland nut onto valve
body.
d) Install 1/4” water supply line from
humidifier using compression
fittings.
e) You are now ready to pierce the
pipe. Turn handle until spindle is
firmly seated into valve body. The
water pipe is now fully pierced.
Turning spindle in shuts valve off.
Open valve completely for normal
operation.
3 Use this template for marking the
unit opening to be cut in plenum. Draw
a level line at least three inches above
furnace jacket for clearance of the
drain line and solenoid valve. Tape
template in position and trace around
entire outside edges. Remove
template and accurately cut the
plenum opening accordingly, being
careful to avoid injury from sharp
edges.
LOCATION
1. Locate Humidifier Control on inside wall
of living area approximately 5’ above
floor, or in the furnace return air plenum
or duct. For return air plenum
installation use Humidifier Control
Adapter Plate, Fast part # 4463
{Not Included) .
Do not locate control in the direct path of
furnace discharge air or drafts from open
doors and windows.
Do not install where operation might be
affected by lamps, sunlight, fireplace
registers, radiators, concealed air ducts
and pipes, or room occupants.
The basic rules for location of
thermostats also apply to Humidifier
Control
TO INSTALL ON STEEL OR BRASS
PIPE
a) Shut off water supply. Open any
faucet to relieve water pressure.
b) Drill 3/16” diameter hole into pipe
where saddle valve will be placed.
c) Place rubber gasket in center of
hole in top saddle clamp.
d) Place top saddle clamp assembly
over hole so that lance fits into
hole,
e) Place top and bottom saddle
clamp around water pipe.
f) Screw valve body into opening in
top saddle clamp and tighten.
g) Tighten gland nut onto valve
body.
h) Install 1/4" water supply line from
humidifier using compression
fittings.
NOTE: For pipe over 1" O.D., use
1/4"-20, 1-3/4" long bolts.
4 Place the unit into the plenum
opening so that the locking tabs on
the bottom are closed down onto the
lower sheet metal edge. While holding
the unit in place, install two screws at
the top of the unit interior. *
GENERAL INSTRUCTIONS
1. DO NOT ATTEMPT TO REPAIR OR
RECALIBRATE CONTROL. Controls
requiring service should be returned to
your distributor.
Control must be installed using 24 volts!
Make sure no bare wires are exposed or
insulation damaged. Insulation on wire
should extend to head of binding screws.
- Make sure all splices are mechanically
and electrically secure.
To rernove dirt or other foreign matter
from nylon ribbon and control interior,
dust lightly with a fine, soft brush.
1 0 Connect 1/2” LD. plastic hose
(not furnished) from unit to floor
drain. Be sure drain hose has
continuous slope. Use caution with
hose clamp, be sure not to over
tighten and crack drain spud. Note:
Do not sweat or directly attach
metal drain line to fitting. Do not
use solvent type adhesive when
connecting plastic drain hose,
since damage to fitting could
result.
5 install a 6° collar in a convenient
location on the opposite plenum. Slip
on a 90° elbow and measure the
length of 6" round duct required to
make the connection. The 6° duct will
fit into the round collar on the side of
the unit. If the furnace has central air
conditioning, add a duct damper.
Assemble components with sheet
metal screws. Support bypass ducts
in excess of 4 to prevent sagging.
8 Tap into a water supply line with
the saddle valve furnished. The humid-
ifier will function with cold, hot, soft-
ened or unsoftened water. The use of
service hot water (140°F MAX.) and
constant blower operation will pro-
vide maximum evaporative capacities.
NOTE: The saddie vaive is designed
to be fully opened or closed. Do net
use it to regulate water flow.
1 1 Open saddle valve and turn on
furnace. Turn up Humidifier Control
to operate unit. Allow unit to run until
water is observed coming out of
drain line. Check to see if unit is
water tight and all electrical
components function properly. Reset
Humidifier Control to recommended
level.
