3-LV-1-7 9/7/11 LV1 User Manual 3-9
1. Turn on the Master Power On/Off switch at the rear of the LV1.
2. Press the blue Reset button located on the control panel.
3. Rotate the Mode switch to the Jog position. The motor should turn on. Press and hold
the Extend button for about 15 seconds to fully extend the piston.
4. Rotate the Mode switch to the Run position, and wait until the Ready light turns on,
causing the motor to turn off automatically.
5. While pressing and holding the Extend button and looking at the Process Pressure
Gauge, turn the Process Pressure Adjustment knob to set the process pressure.
6. Dial in required pressure and be sure to add 10% to the required pressure. For
example, if 20,000 psi is the required pressure, the unit should be set to about 22,000
psi. For priming, set the pressure to about 10,000 psi.
7. Refer to drawing #801.00115 on the CD. Fill the inlet reservoir/syringe (1) (located on
the left when facing the unit), and attach it to the inlet tube (5) via the luer fitting.
Depress the inlet reservoir/syringe to inject the priming liquid into the pump head.
Liquid may flow out of the outlet/discharge tube. Attach the outlet syringe (1)
(located on the right when facing the unit), to the outlet tube, making sure that the
syringe's piston is bottomed out.
8. Switch to Jog mode and wait about 10 seconds for the hydraulic system to unload (this
will generate an audible sound that will cease upon completion).
9. While pressing and holding the Retract button, depress the reservoir/inlet syringe to
force fluid into the pump head. The fluid in the reservoir will be pulled in rapidly. Be
sure there is sufficient fluid in the reservoir to supply the pump head.
10. When the piston is fully retracted, rotate the Mode switch to the Run position.
11. When the Ready light comes on, press and hold the Extend button for about 2 seconds
to initiate a high pressure stroke.
12. Repeat steps 3 through 12 until the fluid stream purges out the air.
13. Rotate the Mode switch back to the Off position.
14. Turn off the Master Power On/Off switch.
Operating the Equipment
WARNING: BEFORE THE HIGH PRESSURE STROKE, BE SURE THE PISTON OF THE OUTLET
SYRINGE IS FULLY PUSHED INTO THE BORE OF THE SYRINGE, ELSE THE PISTON MAY BE SHOT
OUT AND INJURY MAY OCCUR. DO NOT ALLOW THE OUTLET SYRINGE TO OVERFILL!
