Walton SF-5, SW-5 Installation And Maintenance Manual

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 "0") 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.

No obstacle within this region
to prevent wetting objects
For one

and

two way domes, L = 41"

For standard dome, L = 6' -

GENERAL NOTES:

1.

Water reservoir must

be

level.

2.

Keep water supply piping close to hanging strap.

3.

Use a humidistat for automatic operation,

4. Use Reverse

Osmosis for poor quality water.

//

Positive Capacity Atomizing Humidifiers

produce a fine vapor that will quickly evaporate

in
the air if there is no impingement of water particles
against obstructions before absorption

is

complete.
Strict attention to minimum clearance dimensions
must

be

adhered to

in

order to avoid condensation.
