pressure inside the cabinet may cause the doors to flex
inward. Tests should be performed with the exhauster
running.

5.6
Cabinet Air-Inlet Damper (cabinet static
pressure)
5.6.1
Once the inlet is initially set per Section 2.13, it
seldom requires readjustment. The initial setting
produces approximately .5
to .75
of static pressure in
the cabinet enclosure.
Do not confuse cabinet static
pressure with reclaimer static pressure which is
controlled by the dust collector damper, as noted in
Section 5.3. Reclaimer pressure must be set before
cabinet pressure.
5.6.2
Using a manometer (as noted in Section 5.7 and
listed in Section 9.1) is the most accurate method of
monitoring and adjusting cabinet pressure. Following the
instructions packed with the manometer, start the
exhauster and insert the needle into a glove, and adjust
pressure using the inlet damper. Open the damper
farther to decrease static pressure or close it farther to
increase pressure.
5.6.3
If a manometer is not available, use the gloves
as an indicator. With the exhauster running, the gloves
should be inflated, but not elevated off the grate.
5.7 Optional
Manometer
NOTE: These instructions show several methods of
taking static pressure readings (negative pressure) on
cabinet reclaimers using a flexible tube manometer. Use
the method best suited for the application. The
instruction explains the processes for taking periodic
readings and shows how to permanently install the
manometer for taking frequent readings. Permanent
fittings should be installed when rigid ducting is used, or
when the manometer installation is permanent. Use
silicone sealer or other sealant to seal around the fitting
to prevent leaks. The fitting should be capable of being
capped when the manometer tube is removed. Capping
the fitting will prevent leaks that alter the reclaimer’s
separation efficiency. The readings are reference points
so it doesn’t matter where the readings are taken as
long as they are always taken at the same location.
Taking readings at different locations could produce
different results. Static pressure readings at the door are
generally 0.5" to 1" lower than those taken above the
reclaimer.
5.7.1
Refer to directions packed with the manometer
for preparation and operating instructions for the
manometer.
5.7.2
Connect one end of the 3/16" ID tubing to one of
the tubing connectors (elbow) at the top of the
manometer, by pushing it over the barbed adaptor.
5.7.3
Leave the needle protector on the needle and
insert the needle into the other end of the tubing. The
ends of the tubing must fit tight on the manometer and
needle; leaks will give inaccurate readings.
5.7.4
Open both manometer valves (elbows) per the
instructions provided with the manometer.
5.7.5
Magnets on the manometer hold it in position on
the reclaimer body. The manometer must be vertically-
plumb so the fluid is level on both sides.
5.7.6
Adjust the slide rule to align the zero with the
fluid level. Refer to Figure 18.
5.7.7
Needle placement: Ref. Figure 17.
5.7.7.1
Taking readings in the flex hose:
Remove the
needle protector, and insert the needle into the flex hose
approximately 8" from the top of the reclaimer.
5.7.7.2 Taking readings at the reclaimer door:
Open
the reclaimer fill door, remove the needle protector and
place the needle so the point is inside the door opening.
Carefully close the door on the needle. The side of the
needle will embed into the rubber, creating an airtight
seal.
Over-travel Stop
Adjusting Screw Nut
Loosen, and move sideways to
center the adjusting screw on the
over-travel stop.
Adjusting Screw
Adjust the screw to depress the
valve stem when door is closed.
Actuator Adjusting Bracket
Loosen the bracket screws, and
move the bracket up or down to
center the adjusting screw on the
over-travel stop.
