D. Continue to install the bag frame assemblies in the same

manner working from the back of the separator toward the
access door. Place the remaining three or four bag frame
assemblies into the separator before attaching each of them
to their respective collars.

E. When all of the bag frame assemblies are installed the sep-

arator is ready for installation or reuse.

Step Two: Using the lifting rings provided, stand the separator
in an upright position and locate the separator in its installation
area either on its legs or by using the I-beam mounting lugs, if
you have ordered your separator with this mounting option.
(see Figure 1)

Step Three: A manometer, which indicates pressure drop
across the filter bags, is supplied with each Jet-Clean Separator
to assist in selecting the optimum bag cleaning frequency for
each individual installation. With most materials, bags should be
cleaned with a frequency that maintains a maximum pressure
drop across the bags for approximately 4” of water.

Two pressure taps, one on either side of the bag head, are
located near the top of the separator opposite the air supply
tank. After pouring the liquid (supplied with the manometer)
into the manometer tube, connect the two manometer tube
ends, one to each tap, and mount the manometer on the side of
the separator by means of its magnetic mount. (see Figure 2)
Install the manometer while the system is not in operation to
prevent the manometer liquid from being pulled into the
Separator.

Caution: When the unit is installed outdoors and tempera-
tures below 32°F (0°C) are expected, be sure to use the
supplied liquid which will not freeze.

This manometer has been calibrated to use only the oil supplied
(0.826 sp. gr.). For replacement oil, contact the factory.

Step Four; Installation of Bag Pulse Sequencer:

Air Supply Connection

Remove the threaded plug from the 1” N.P.T. female pipe fitting
located at “A” which is the end of the air supply tank and connect

a supply of 100 psi to 125 psi air to the separator’s tank at this
point. All other connections have been made at the factory.
(see Figure 3)

Electronic Sequencer Connection (Standard)

A 120 VAC 60 cycle input must be wired to the control unit. The
hot line must be connected to the door mounted selector switch
and the neutral line must be connected to terminal 12 on the
printed circuit board.

Important: The 100 psi to 125 psi air supplied to the separator
must be oil-free, clean and dry (suitable for use with air-operated
valves and controls) and must be available at a rate of at least
15 cfm in order to properly operate the unit and provide clean,
dry air for bag cleaning.

No adjustments should be made to the internals of the
sequencer of the Jet-Clean Separator except for cycle time.
Each unit is completely tested prior to shipment and is preset
for proper operation at the factory. Any malfunction of the
control should be reported to your Spencer Representative or
to The Spencer Turbine Company Service Department in
Windsor, Connecticut.

IV. Operation
and Maintenance

Caution: The Spencer Turbine Company is not responsible
for wear or corrosion caused by the material being handled
or failure due to corrosion or abrasion.

Removal and installation of
twist-off Jet-Clean Separator Bag Frames

The Spencer twist-off bag frame assembly is unique because a
simple turn allows for easy removal or reinstallation. A locking
bolt prevents inadvertent loosening of the unit. To change the
filter bag, proceed as follows:

1. Locate and loosen the locking bolt.

2. Twist the bag frame in a counter-clockwise direction and

allow the male pins on the bag frame to ride down the
guides located on the frame collar.

3. Remove the bag frame assembly from the separator.

4. Loosen the bag clamp and remove the filter bag.

5. Install a new filter bag and re-tighten bag clamp.

6. Re-insert bag frame assembly into the separator. Note here

that when the bag frame is secure on the bag collar the
locking bolt must be visible in order to be tightened.

7. With this in mind, raise the bag frame assembly into contact

with the bag collar and turn in a clockwise direction to re-
engage the frame pins into the holder guides.

8. When the bag frame assembly is fully hand-tightened, tighten

the locking bolt.

Description and adjustments for the Electronic Sequencer

The Electronic Sequencer furnished by Spencer contains the
following standard design features: Solid state controls, solenoid
pilot valves, 120 VAC 60 Hz input and NEMA 12 enclosure.
NEMA 4 and NEMA 7 & 9 enclosures are optional.

There are three adjustments that can be made on the Electronic
Sequencer. The first, Pulse Time, which is the actual length of
time that the air blast lasts, is adjustable from 0.1 second to
1.0 second. The second, Step Time, which is the length of time
between pulses, can be adjusted from 1.0 second to 1.0
minute. The third, Cycle Time, the time between cycles, can be
adjusted from 1.0 minute to 1.0 hour.

These adjustments are made by using a pocket size screwdriver
to turn the required potentiometer clockwise to increase; counter-
clockwise to decrease.

Cycle Time – 1 minute to 1 hour (preset at 10 min.)

Pulse Time – 30 milliseconds to 1.2 seconds (preset at 450 m.s.)

Step Time – 1 second to 60 seconds (preset at 7.5 sec.)

1. Output starts at No. 1, then No. 2 and so on to the last selected

output, then back to No. 1 after Cycle Time is completed.

2. Turning selector switch on “OFF” then back to “ON” resets

the above.
