Humidity Source SF-10 Installation And Maintenance Instructions

MODEL SF-10, SF-10, 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
INSTALLATION AND MAINTENANCE INSTRUCTIONS
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.
