Model 592-22
Power-Spray Humidifier
24-Volt
IMPORTANT:
THIS HUMIDIFIER MUST BE INSTALLED BY A QUALIFIED CONTRACTOR.
DO NOT INSTALL ON ANY SYSTEM WITH WATER PRESSURE
LESS THAN 40 P.S.I.
Installation on water systems with hardness ratings greater than 7 grains
is not recommended. Such installations can result in nozzle blockage,
dripping, erratic spray patterns and other maintenance problems.
Hardness above 7 grains will also produce dust from solids in the water
supply, which will be distributed throughout the home. Consult your
municipal water provider before continuing.
SAFETY PRECAUTIONS
READ THESE PRECAUTIONS AND ALL INSTALLATION INSTRUCTIONS
BEFORE INSTALLING THE HUMIDIFIER.
NOTE:
Skuttle Mfg. Co. assumes no responsibility under warranty
if installer does not follow these instructions and safety precautions.
Do not install a humidifier where the heating temperatures can exceed 200°F.
Excessive temperatures will harm the humidifier, possibly causing water
damage to the home.
Do not install a humidifier where the surrounding temperature can be 32°F
or colder. Frozen water will damage the humidifier and burst the supply
pipe, resulting in home damage.
Do not cut or drill into any air conditioning or electrical accessories during
humidifier installation.
DANGER: Electrocution is possible if you come
in contact with a live wire; blindness can occur if refrigerant contacts
your eyes.
When the humidifier is installed in an area where water damage could
occur, connect the humidifier’s overflow provision to a suitable drain pan.
For above-ceiling installations, always install a drain safety pan, plumbed to
a suitable drain.
For initial recommended humidistat settings, refer to Table 1, below. (Be-
cause relative humidity affects people differently, these settings can be
raised or lowered slightly to suit personal comfort levels.)
CAUTION: Setting the humidistat higher than the recommended set-
ting can cause condensation, resulting in home damage.
If excessive
moisture appears on windows or walls, reduce the humidistat’s humidity
setting enough to eliminate condensation. If the situation continues, turn off
the humidifier’s water source until condensation is gone.
Make sure the installation, wiring and plumbing of the humidifier comply
with local codes, ordinances and regulations.
INSTRUCTIONS
IMPORTANT: This product should not be used in conjunction with heat
pump systems.
For heat pumps, select Skuttle Model 592-9, or upgrade to
Models 55UD, 86UD, or a 60-series steam humidifier.
GENERAL INFORMATION:
1.0 This humidifier puts moisture into the home by spraying a fine mist of water
into the warm air plenum, which is carried into the living area by the duct system.
1.1 When wired as recommended, the humidifier will operate only when the
furnace blower is in operation and the humidistat is calling for humidity.
1.2 The nozzle capacity (flow) is rated at 40 P.S.I. This capacity varies accord-
ing to line pressure, as shown in Table 2, below.
EXAMPLE:
A home which requires .50 gallons of water per hour for proper humidifica-
tion, and which has a water pressure of 80 P.S.I., would need a .37 nozzle to do the job.
1.3 If the water pressure is excessive, a pressure regulator valve will be neces-
sary to obtain the proper volume of moisture.

2.0 Aviation Snips • 1/4" Flathead Screwdriver • #1 Phillips Screwdriver •

GENERAL INFORMATION:
3.0
CAUTION:
When selecting a location for the humidifier, make sure the
spray will not impinge or accumulate on any fan, limit controls, heating parts or
A-coils.
3.1 Select a location where the air will push the spray mist away from the
humidifier.
3.2 Mount the humidifier on the hot air
plenum only, with the nozzle pointing up in
the direction of airflow (see Figure 1, left).
On narrow plenums, mount the humidifier
on the narrow side.
3.3 If there is not enough room on the hot
air plenum, mount the humidifier further
downstream on the warm air duct, away
from the heating and cooling coil.
3.4 If it is necessary to mount the spray
nozzle further away from the humidifier (in
order to move the nozzle further into the
air stream for better absorption), remove
the nozzle adapter and 45° fitting from the
solenoid valve. Use the fittings supplied in
the parts bag to relocate the nozzle using
1/4" copper tubing (not supplied). (See
Figure 2, below, left.)
CAUTION:
Do not
allow copper tubing to come in contact
with sharp edges or surfaces that may
cause wear on the tubing.
3.5 Tape the template
(provided) on the warm air
plenum in the location
selected for the humidifier.
CAUTION:
Make sure the
template is level.
3.6 Center punch and drill
four 7/64" mounting holes,
as shown on the template.
DANGER:
Make sure you
are not cutting or drilling in-
to air conditioning or elec-
trical accessories.
3.7 Drill a 3/8" hole in the
center portion of the tem-
plate and cut a rectangular
opening, as instructed on
the template.
3.8 Install the drain cup
over the nozzle; attach it
with a #6 x 3/8" sheet
metal screw. (See Figure
3, left.)
3.9 Install 3/16" I.D. tubing
on the copper humidifier
drain and run it to a waste
drain. (An occasional drip
from the drain tube when
the humidifier is operating
is normal.)
3.10 Attach the humidifier
with four #8 sheet metal
screws.
PLUMBING THE HUMIDIFIER:
4.0 Select the nearest cold water pipe and install the saddle connector and
needle valve, supplied with this unit.
USE COPPER TUBING ONLY.
The needle valve is a self-piercing valve when installed on copper pipe.
Follow the instructions supplied with the valve.
Mount the valve so that water will come from the top or side. This will re-
duce the chance of minerals clogging the valve.
4.1 Follow these compression plumbing tips:
Lightly clean the tubing ends with fine sandpaper before making connec-
tions.
Make sure the tubing is fully inserted into the fitting before tightening the
compression nut.
4.3
IMPORTANT:
After attaching the saddle valve, thoroughly flush the supply
tubing to clear the line.
Otherwise, debris could block the water flow at the sole-
noid valve.
4.4
IMPORTANT:
To assist you with cleaning, note the proper orientation of
parts for assembly and disassembly. (See Figure 4, on back.)
