Heart of the unit
The heart of Humidity Source humidifier units is the patented
masterfully engineered Centrifugal Atomizer. Water is drawn by
centrifugal force up through the rotating impeller cap and pump tube,
then spun across the disk rotating at 3250 RPM striking the Vapor­Maker Comb creating an extremely fine vapor. An integral fan under
the rotating disk blows the vapor out of the unit resulting in a fine
atomized vapor that is quickly absorbed into the air.

HUMIDITY SOURCE ATOMIZING

humidifiers produce moisture that will quickly
be absorbed in the air. However, it is very important that the humidifier be installed so
that there is no chance of the moisture striking any object before it has been absorbed
by the air. If any solid is hit with air containing suspended or unabsorbed moisture,
condensation and dripping will result. It is therefore most important that all directions and
minimum dimensions be strictly adhered to.

MODEL SW-2

Your humidifier has been designed and engineered to
give, with proper care, many years of trouble free
service. Therefore, if this unit ceases to operate
properly, we suggest you contact your local dealer. If
we, at Humidity Source, can be of any assistance to
you, please feel free to write, call or e-mail.

IMPORTANT

This space type humidifier is designed so that it may
be shelf mounted. The shelf should be at least 18”
(45.7cm) below the ceiling and 6 feet (1.8m) above
floor. The directional vapor dome should be positioned
to diffuse moisture without striking any obstructions
closer than six feet and maintain 24” minimum between
each side of the humidifier and any wall or obstruction.

PROCEDURE

Run a water supply line using 1/4” o.d. copper or
plastic tubing or 1/8” pipe. Keep the line to the rear of
the unit to avoid creating an obstruction.

Flush water feed lines before making final connection
to avoid having cutting oil, pipe scale, or chips which
may clog the float valve.

Turn on water valve and adjust water level to 1/2”
below the overflow connection by adjusting the thumb
screw as shown in Figure 1.

Adjustment is easily made using the adjusting thumb
screw for higher or lower water level as illustrated.

SERVICE & REPAIR

Should this humidifier need service or repair some time
in the future, return only atomizing unit direct to the
factory.

CARE OF THE MACHINE

Due to air washing while the humidifier is in operation,
a deposit of dirt and dust may settle in the bottom of
the water reservoir and screen, and it is recommended
that both be cleaned regularly.

WIRING

The atomizer motor draws .67 Amps at 115 Volts A.C.
single phase and 60 Hz service.
Provide standard electric receptacle to receive electric
cord from humidifier. Have the hot leg of service to this
receptacle wired in series with the humidistat terminals
and use a standard disconnect switch if required. See
wiring diagram.

This humidifier may be run continuously or operated by
means of a humidistat.

Our standard human hair element humidistat model P­825 is correct for most applications maintaining up to
60% RH.

For humidors and other high humidity applications, or
for more precise control, use the electronic humidistat
model W351A. This model also has an optional digital
display module to indicate the set point and the actual
R.H. in the room.

OPERATION

Positive capacity atomizing humidifiers produce a mist that
will quickly evaporate into the air if there is no impingement
of water particles against barrier surfaces before the water
particles against barrier surfaces before the water is
completely absorbed. Strict attention to minimum clearance
dimensions must be adhered to in order to avoid
condensation.

MAINTENANCE

Unplug electric cord & remove dome. Carefully lift atomizing
unit out of reservoir (Figure 2). Hold atomizing unit firmly
and remove the perforated screen (2-A) by turning it slightly
to the left until the four lugs are in line with the slots. To
remove the impeller cap (2-B), hold a flat file or the back of a
table knife flat against the side of the tube and gently tap the

cap which is held in place by a pressed fit. After the cap has
been removed, the inside of the tube is visible and it is
simple matter to clean it with a piece of cloth on the end of a
screwdriver or a small round brush.

There are three ports through which water makes its way
from the pump tube to the top of the rotating disc (2-C).
These ports should be cleaned out with the aid of a wire.
See drawing on this page.

Replace the impeller cap by tapping it evenly back into
place, using plastic handle on screwdriver.

Remove water from reservoir & rinse. Fill reservoir with
white vinegar or other mild acid solution. Replace dome &
atomizer on reservoir & block outlet of dome with plastic
wrap & a rubber band. Run atomizer for ½ hour or until
minerals are completely dissolved. If necessary, rinse with
diluted chlorine bleach solution. Rinse with clean water and
return to service. For hard water problems, see
“demineralized water” below.

Inspect float valve assemble periodically, & replace when
necessary, or every few years. Should this humidifier need
service or repair some time in the future, return only
atomizing unit direct to the factory.

DEMINERALIZED WATER

If your local water supply has a high mineral content, (call
water company & ask for “total dissolved solids” or T.D.S.)
This mineral will create tiny particles of airborne “white dust”
when the mist evaporates in the air. To eliminate this dust,
use an ion exchange or a reverse osmosis demineralizer.
See Humidity Source data sheets for Reverse Osmosis
demineralizing filters.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

MODEL SF-5 and SW-5

GENERAL INFORMATION

This space type humidifier is designed to be
suspended from the ceiling or mounted on a shelf.
Hanging brackets are provided but supports from the
ceiling or shelf must be furnished by others.
The humidifier consists of two assemblies; the water
reservoir which includes a float type water level valve
with 1/8” male pipe thread connection and a safety
overflow port and the atomizer assembly which is a
delicately balanced, completely self-contained unit
that rests in the water reservoir and supports the
directional vapor distribution dome.

PROCEDURE

When selecting exact location for each humidifier be
sure that the vapor discharge is approximately six feet
from the any obstruction such as lights, pipes or
beams. Vapor must also avoid touching humidifier
wiring and supports. The following procedure is
recommended.

1. Obtain the correct type of vapor distribution
dome for each humidifier location.

2. At each location place the correct dome in the
reservoir and install one hanging bracket
above the water inlet valve, above the position
of the water valve on the side of the tank. Then
rotate and position the dome so that its vapor
ports will avoid this bracket.

3. Place the other hanging brackets in a position
which will give level, secure suspension and at
the same time will avoid striking the hangers
which are to be attached to these brackets.

4. After positioning the reservoir to avoid vapor
touching any existing obstructions, locate
points on the ceiling directly above the
brackets and connect suspension straps or
rods at these points. See Figure “B” for further
details.

NOTE: ALL MINIMUM INSTALLATIONS
DIMENSIONS AS SHOWN IN FIGURE “A” MUST
BE FOLLOWED.

PLUMBING

Insert the float valve assembly as illustrated in
Figure “C”. Run a water supply line near the

ceiling and drop a 1/4" tubing line ( or 1/8” pipe)
from the supply line. Keep the drop very close to
one of the hangers to avoid creating an
obstruction.
Flush all water feed lines before making final
connections to avoid clogging the float valve with
foreign matter.
Adjust the position of float valve stem to establish a
water level in the reservoir about 1/2” below the
overflow fitting. See Figure “C” for location of
adjusting screw.
Be sure that the water valve arm is directed toward
the center of the reservoir when tightening the
mounting nut.

FOR MODELS WITH FILTER

Place the filter in the reservoir with wide flange on
top, and the notch directly above marker near
water inlet position. Place atomizer assembly into
this flange positioned so that the motor extension
cord matches the notch in the flange. This avoids
the possibility of atomizer legs interfering with the
operation of the water regulating valve.
Place vapor dome over the atomizer assembly and
run electric cord along one hanger to a female
receptacle. Wiring to the receptacle should be
through a humidistat control that will operate the
humidifier. Refer to Figure “E” for wiring diagram.
Due to a certain amount of “air-washing” when the
humidifier is operating, an accumulation of dust
and dirt may settle at the bottom of the reservoir. It
is therefore recommended that periodic inspection
and cleaning be performed as necessary. Also the
water drain plug or valve should be opened
frequently and the water line flushed out. This
periodic maintenance can greatly extend the life of
the humidifier.

IMPORTANT:
IT IS NECESSARY TO KEEP THE RESERVOIR
AND ATOMIZER UNIT CLEAN IN ORDER TO
MAINTAIN FULL HUMIDIFIER CAPACITY AND
NOT OVERLOAD THE MOTOR.

MAINTENANCE

As stated above, the water reservoir and pump
tube must be kept clean and free of minerals, scale
and dust. Periodically remove atomizer assembly
and clean reservoir with white vinegar. Carefully
remove impeller cap (see Figure “D”) and clean
pump tube with pipe cleaner or test tube brush.
Motors have sealed bearings and do not require
lubrication.

SERVICE

Atomizer motors are sealed in a copper housing at
the top of the atomizer assembly. DO NOT
BREAK THIS SEAL. If for any reason a repair
becomes necessary, carefully package the entire
atomizer assembly and return intact to your
installer, local distributor or Humidity Source, LLC.
When ordering parts have model number and
voltage available.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

MODEL SF-10, SF-10B, and SW-10, SW-10B

GENERAL INFORMATION

This space type humidifier is designed to be
suspended from the ceiling or mounted on a shelf.
Hanging brackets are provided but supports from the
ceiling or shelf must be furnished by others.
The humidifier consists of two assemblies; the water
reservoir which includes a float type water level valve
with 1/8” male pipe thread connection and a safety
overflow port and the atomizer assembly which is a
delicately balanced, completely self-contained unit that
rests in the water reservoir and supports the directional
vapor distribution dome.

PROCEDURE

When selecting exact location for each humidifier be
sure that the vapor discharge is approximately six feet
from the any obstruction such as lights, pipes or
beams. Vapor must also avoid touching humidifier
wiring and supports. The following procedure is
recommended.

1. Obtain the correct type of vapor distribution
dome for each humidifier location.

2. At each location place the correct dome in the
reservoir and install one hanging bracket above
the water inlet valve, above the position of the
water valve on the side of the tank. Then rotate
and position the dome so that its vapor ports
will avoid this bracket.

3. Place the other hanging brackets in a position
which will give level, secure suspension and at
the same time will avoid striking the hangers
which are to be attached to these brackets.

4. After positioning the reservoir to avoid vapor
touching any existing obstructions, locate points
on the ceiling directly above the brackets and
connect suspension straps or rods at these
points. See Figure “B” for further details.

NOTE: ALL MINIMUM INSTALLATIONS
DIMENSIONS AS SHOWN IN FIGURE “B” MUST
BE FOLLOWED.

PLUMBING

Insert the float valve assembly as illustrated in
Figure “C”. Run a water supply line near the ceiling
and drop a 1/4" tubing line ( or 1/8” pipe) from the

supply line. Keep the drop very close to one of the
hangers to avoid creating an obstruction.
Flush all water feed lines before making final
connections to avoid clogging the float valve with
foreign matter.
Adjust the position of float valve stem to establish a
water level in the reservoir about 1/2” below the
overflow fitting. See Figure “C” for location of
adjusting screw.
Be sure that the water valve arm is directed toward
the center of the reservoir when tightening the
mounting nut.

FOR MODELS WITH FILTER

Place the filter in the reservoir with wide flange on
top, and the notch directly above marker near water
inlet position. Place atomizer assembly into this
flange positioned so that the motor extension cord
matches the notch in the flange. This avoids the
possibility of atomizer legs interfering with the
operation of the water regulating valve.
Place vapor dome over the atomizer assembly and
run electric cord along one hanger to a female
receptacle. Wiring to the receptacle should be
through a humidistat control that will operate the
humidifier. Refer to Figure “E” for wiring diagram.
Due to a certain amount of “air-washing” when the
humidifier is operating, an accumulation of dust and
dirt may settle at the bottom of the reservoir. It is
therefore recommended that periodic inspection
and cleaning be performed as necessary. . Also the
water drain plug or valve should be opened
frequently and the water line flushed out. This
periodic maintenance can greatly extend the life of
the humidifier.

IMPORTANT:
IT IS NECESSARY TO KEEP THE RESERVOIR
AND ATOMIZER UNIT CLEAN IN ORDER TO
MAINTAIN FULL HUMIDIFIER CAPACITY AND
NOT OVERLOAD THE MOTOR.

MAINTENANCE

As stated above, the water reservoir and pump tube
must be kept clean and free of minerals, scale and
dust. Periodically remove atomizer assembly and
clean reservoir with white vinegar. Carefully remove
impeller cap (see Figure “D”) and clean pump tube
with pipe cleaner or test tube brush.
