CENTRIFUGAL ATOMIZER
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 Vapor-Maker 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 POSITIVE CAPACITY ATOMIZING humidifiers produce
moisture that will quickly
be
absorbed
in
to
the air stream, provided there
is
no
impingement. It
is
therefore most important that
all
directions
and
minimum dimensions
be
strictly adhered
to
In
order
to
avoid condensation.

PRELIMINARY CONSIDERATIONS
Before proceeding with the installation, the location of Model
WF-HH-229 Humidifier must
be
selected. There are several
through-the-wall considerations that can be chosen, utility or
equipment rooms, a dead space area, closet space, etc.
Step
1.
Select a location for your humidifier so that there will
be
6 feet minimum space between the Escutcheon side if the
wall and the nearest wall or obstruction. There should also be
6 V, feet minimum distance to the floor and at least
12
inches
from the ceiling (see Figure A). Failure to follow the
minimum distance guidelines may result
in
moisture
on
the walls or ceiling.

Step
2.
Use the Mounting Bracket
as
a template and mark the
location for
(2)
W' diameter holes and slot for humidifier
discharge tube (Figure
B).
Drill the W holes and cut the slot
in
the wall board
on
the unit side only. Cut a 3
W'
hole
in
the
Escutcheon or unit discharge side
of
the wall to allow the
extension tube to protrude through the wall. Establish a
2"
per
foot pitch toward the humidifier when cutting the 3
v,"
hole.
Step
3.
Fasten the Mounting Bar to the top of the Mounting
Bracket with
(2)
~"
bolts as shown
in
Figure
C.
Mount the
entire assembly to the wall with
(2)
#12 wood screws through
the Mounting Bracket.. The Mounting Bar is sized to match
normal wall stud spacing (16" centers). Insert (3) rubber feet
in
the bottom
of
the mounting plate, with rubber bumper up
12" Min.

4.
Place the Reservoir assembly
on
the Mounting
Bracket. Run a
~"
copper or PVC tubing line from
an
appropriate water supply to the Reservoir float valve fitting.
It
is
recommended that a shut off valve
be
located at the water
supply connection
in
case
of
water leaks and for easy removal
of humidifier for maintenance. Turn
on
the water and adjust
the Reservoir water level to
1"
below the over flow port using
the float valve adjusting thumb screw (Figure
D).

5.
Cut the Extension Tube to the correct length
depending
on
your wall thickness. Allow sufficient Extension
Tube length (%") protruding through the wall to mount the
Escutcheon. Do not cut the Extension Tube at the rubber seal
end and smooth all rough edges after cutting.
Step
6.
Slip Rubber Sealer end of the extension tube
all
the
way over the Vapor Tube. Roll the top layer
of
the Rubber
Sealer off the extension tube and
on
to the Vapor Tube (Figure
E).

Step
7.
Insert the Vapor Dome with Extension Tube through
the wall from the humidifier side as shown
in
Figure
F.
The
Extension Tube should have a downward pitch toward the
humidifier of approximately
1"
per foot. Place Vapor Dome
on
top
of
Reservoir and connect Dome Strap. Water placed
in
the
Extension Tube should
run
back into the humidifier,
if
not
wedge a piece of spacing material (like a piece of wood) under
the Extension Tube to raise
it.
Step
8.
Adjust the two rear rubber feet
on
the Mounting
Bracket to snug the Reservoir up against the front rubber foot
to keep the reservoir firmly
in
place.
Step
9.
Assemble the Escutcheon to the protruding Extension
Tube as shown
in
the two steps shown
in
Figure
G.
Step
10. Make electrical connections as shown
in

The Humidity Source Humidifier is now ready for many years
of service.

Your
Humidity
Source
humidifier
is a precision-built
instrument that, given proper care, will provide years of
dependable service. All that is required
is
periodic cleaning
during the humidifying season when your humidifier
is
most
used. Depending
on
local water conditions, mineral solids and
other matter may accumulate
in
various parts
of
the unit.
These accumulations must be removed so that water flows
freely for efficient operation
of
the humidifier. A reverse
osmosis water treatment system will remove minerals and
greatly reduce the need to clean the humidifier.

CLEAN YOUR HUMIDIFIER AT END OF THE HEATING
SEASON. LEAVE THE UNIT EMPTY AND DRY

IN
THE
FALL. INSPECT AND CLEAN (IF NEEDED) ONCE OR
TWICE DURING THE HEATING SEASON.
IF

YEAR, INSPECT AND CLEAN AS NECESSARY
QUARTERLY
STEP
1.
DISCONNECT ELECTRICAL PLUG FROM HOUSE LINE.
TURN OFF WATER SUPPLY.
STEP
2.
REMOVE DOME FROM UNIT, AFTER FIRST REMOVING
DOME STRAP. The dome rests
on
the copper motor pan;
it
lifts up and away from the unit. The vapor tube and extension
tube are connected by the rubber tube seal and will come out
together.
STEP
3.
LIFT OUT THE ATOMIZING UNIT. This rests freely
in
the
reservoir pan and lifts out easily.
STEP
4.
CLEAN THE ATOMIZING UNIT. Do
not
submerge unit
in
water
or
the atomizer motor will be damaged. First, remove the
cylindrical screen. Twist slightly out
of
lock position and
remove. Next, remove the impeller cap from the pump tube
by
tapping lightly
on
edge of cap with a flat object (such
as
a file
or flat screwdriver). Do
not
tap on face
of
cap, this can damage
its ability
to
pump water. Insert a pointed scraper or pipe
cleaner through the open end of the pump tube into the three
apertures located inside the pump tube (you may not actually
see the apertures but you can "feel" them). Gently poke and
free the three apertures
of
any solids that may have
accumulated. Scrape out waste materials along the inner walls
of
the pump tube. Flush out pump tube with low pressure water
being very careful to not force water into the atomizer motor.
Replace impeller cap on pump tube
by
tapping into place
around edge
of
cap, again, do
not
tap face
of
cap. Spin the
pump tube by hand to insure it rotates freely. Replace screen
by
twisting into lock position. Brush-clean the vapor maker
comb with a small wire brush or old tooth brush. Rinse out
motor pan being careful not to get water into the motor.
STEP
5.
EMPTY AND CLEAN RESERVOIR
of
all liquids and waste
materials. Use white vinegar to dissolve minerals. Care should
be
taken so as not to disturb floats or float valve.
STEP
6.
REASSEMBLE THE UNIT. Replace the atomizing unit
in
the
reservoir. Place the dome
on
the motor pan with the discharge
exhaust and extension tube positioned
in
line with the air
intake tube
on
the reservoir. Set entire unit back on mounting
plate positioning discharge tube and air intake tube through the
wall.
TURN
ON
YOUR WATER SUPPLY, PLUG
IN
YOUR
ELECTRIC CORD AND YOUR HUMIDIFIER
IS
AGAIN
READY FOR THE NEXT HUMIDIFING SEASON.
