Walton SF-5 Instruction 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' - 0"

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.
