GROUNDING INSTRUCTIONS
This machine must be grounded. If it should malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of electric shock. This product is equipped with a
GFI plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded
in accordance with all local codes and ordinances.
G.F.I. Plug Operating Instructions (Not supplied on 220 Volt units)
1. The GFI plug has been designed to prevent lethal electric shock by interrupting the circuit
whenever fault-to-ground occurs.
2. The GFI plug instantly opens the circuit when it senses an imbalance of 4-5 milliamps and
it constantly monitors electrical current to a connected load.
3. The GFI plug also offers instant protection from open-neutral conditions that can be
created when a break occurs in the neutral conductor or the power source.
WARNING
!
Warning: Improper connection of this equipment-grounding conductor
can result in a risk of electrocution. Check with a qualied electrician or
service technician if you are in doubt as to whether the outlet is properly
grounded. Do not modify the plug provided with this product. If it will not
t the outlet, have a proper outlet installed by a qualied electrician.
WARNING
!
1. This unit offers NO protection against electrical shock hazard
resulting from defects or faults in any wiring supplying power to the
machine.
2. Ground fault interrupters DO NOT protect against electrical shock
resulting from contact between hot (line) and common (neutral)
conductors of an electrical circuit.
3. If the GFI tests properly without load equipment connected, but
trips each time load equipment is connected, then the equipment
has a ground fault and needs to be repaired or replaced. If that
condition exists, DO NOT BYPASS the GFI as a real shock hazard
may be present.
4. The GFI plug is designed for protective purposes, do not utilize it as
an On/Off switch.
5. Test the GFI plug before each use to ensure proper operation.

Manual Reset
1. Plug the GFI into a 3-wire 120 Volt grounded receptacle.
2. Fully press the reset button marked (marked “R”) and release. The unit should power up
and the amber “POWER ON” light should glow.
3. Fully press the test button (marked “T”) and release. The power light should go off.
4. Press and release the reset button again. Verify that the power light is on and the GFI is
now operational.
5. If the GFI fails to reset, or fails to turn off when all appropriate buttons are pressed, check
to make sure that:
a.) You have fully depressed and released the proper buttons.
b.) There are no loose wire strands or foreign materials in the access chamber of the
GFI plug that may cause a fault.
6. If the GFI still cannot complete the cycle described in steps 2 through 4 above and after
checking the items in step 5,the unit is not functioning. Contact Elliott for repairs.

START-UP
Unpacking
Your Elliott Roto-Jet II® is shipped in a well-packed carton with the electric supply cord attached and
the foot pedal detached. Upon receiving your new machine, inspect the unit for damage. If damage is
discovered notify Elliott and the carrier. DO NOT discard the carton or any packaging. Inspectors will
need to examine both the carton and the contents.
Connecting Instructions (See diagrams on pages 13 & 15)
1. Uncoil the air tubes that are attached to the foot pedal and insert the air tube into the air
port. In the case of a reversing unit, attach the tube of the “right” foot pedal to the “right”
barbed air port on the machine and the tube of the “left” foot pedal to the “left” barbed air
port.
2. Uncoil the exible shaft. Never operate a exible shaft that is coiled. Install the drive
coupling onto the exible shaft. (See diagram 1) Remove the protective cap from the
manifold. Make certain the o-ring is properly installed in the groove of the manifold. Insert
the drive coupling into the drive socket inside the manifold, tighten the manifold cap onto
the manifold. Firm hand tightening will be sufcient.
3. Connect a standard garden hose to the water inlet on the front of the machine. Make sure
the ltered washer is properly installed prior to connecting the water hose. The water
supply may be turned on at any time after connection is made, water will not ow through
the manifold until the exible cable is activated.
4. Select and install the appropriate cleaning attachment to the tool coupling of the exible
shaft.
5. Uncoil the power cord and plug the GFI plug into a properly wired, grounded outlet.
6. Move the power switch located on the opposite end of the unit to the “ON” position.
Depress the foot pedal to test the operation of the exible shaft.
NOTE: Once the exible shaft is activated water will begin to ow through the shaft
casing and exit at the tool end. Make certain that no water is leaking from the manifold
connection or from inside the machine.
Your Elliott Roto-Jet II® is now ready to brush tubes clean.

OPERATION INSTRUCTIONS
1. Using your Elliott catalog or the Elliott Product Selection CD, select the appropriate
exible shaft and cleaning attachments for the tube size and conditions. Thread the
cleaning device into the tool coupling of the exible shaft.
TOOL TIP: When using a reversing direction drive Roto-Jet II®, install a ¼” lock washer
between the tool coupling and the cleaning device. Firmly tighten the connection.
2. DO NOT operate a coiled exible shaft. Set the Roto-Jet II® at a right angle to the tube
sheet of the vessel being cleaned. (See Diagram 2) Position the exible shaft in a large
loop allowing the shaft to enter and exit the tube in a safe radius.
3. Measure the length of the tubes being cleaned. Transfer that measurement to the exible
shaft, from the end of the cleaning device up the exible shaft casing toward the machine.
Mark the casing at that point using electrical tape or a hose clamp snugly tightened on
the casing. This is to prevent the cleaning tool from exiting the tube.
NOTE: Allowing the cleaning device to exit the tube while the shaft is spinning will cause
the shaft core to fracture, breaking the shaft at that end.
4. Insert the cleaning device into the tube end, start the cable rotation by depressing the
footswitch. On the 0650R reversing unit, the “LEFT” footswitch is forward or clockwise
direction drive and the “RIGHT” footswitch is reverse or counterclockwise drive.
a.) Your Roto-Jet II® is equipped with a solid state speed control. This will allow you
to adjust the shaft rotation speed from 0 to nearly 1800 RPM.
b.) We recommend starting at 25% to 50% of the maximum speed for an initial pass
down the tube. Evaluate the level of resistance met and adjust the shaft speed to
allow the safest and most thorough cleaning speed.
5. Beginning at the top of the vessel, proceed to clean row by row, marking each row as it is
cleaned.
