  2. Agenda • General • Air Supply Requirements • Assembly • Assembling the System • Leveling the Table • Isolating the Table • Installing Leveling Valves • Connecting Air Lines • Adjusting Leveling Valves • Troubleshooting

  3. (Payload weight + Table weight) + 10 psi Total isolator diaphragm area (25.9 in2/isolator) Air Supply Requirements • Constant air supply required during operation • Bottled nitrogen • Compressed air • No CO2 (cause freezing) • After initial setup air is only consumed to compensate for load changes • Pressure requirements • Determined by dividing total payload and table weight by isolator diaphragm area + 10 psi.

  4. RS4000-510-8 (1250 lbs) Payload ( 445 lbs) Total (1695 lbs) (445 + 1250) + 10 psi (4 isolators) * (25.9 in2/isolator) Air Pressure Example RS4000-510-8 Weight = 1000*1.2 = 1,250lbs Approximate net weights (±10%) for 4 ft (1.2 m) wide steel tables. For 5 ft (1.5 m) wide models add 20%, for 3 ft (0.9 m) models, subtract 25%. Shipping weights can be estimated by adding 100–200 lbs (45–90 kg) for crate weight. 26 psi =

  6. Assembly – Assembling the system Bolt isolators to table using clips, bolts and wrench provided

  7. Leveling the Table • Place a level on the table top in about the center • Adjust the support as required to level the table • When level, make sure each isolator support is resting against the bottom of the table and is centered between the clips

  8. Isolating the Table - Installing Leveling Valves • 3 valves are used in all systems regardless of the number of isolators • Leveling locations are selected in order to form the largest triangle possible IPV-KT packaged in box IPV valve and associated mounting hardware

  9. Isolating the Table - Installing Leveling Valves Table height sensor Control arm Isolator pressure gauge Air supply Mounting screw holes Metering needle valve Air line to isolator Over-pressure relief valve

  10. Isolating the Table - Installing Leveling Valves • Set the table height sensor adjustment screw to center of travel • Attach the leveling valve to isolator using the 2 mounting screws and nut plate provided • Rotate control arms on valves “A” to point to the outside of the table • Rotate control arm “B” to point to the center of the 2 isolators it is controlling

  11. Isolating the Table - Connecting Air Lines • Connect air lines to the isolator as shown below (use translucent tubing and tee connectors. • Connect grey tubing between the air line to isolator (hose barb) and the isolator A razor blade works best for cutting tubing Grey tubing Tee connectors Translucent tubing

  12. Isolating the Table - Connecting Air Lines One Isolator • The adjacent diagrams detail the valve connections to the isolator Translucent tubing Two Isolators

  13. Isolating the Table – Adjusting Leveling Valves • Close metering needle valve on each valve. Re-open 1/8 – ¼ turn. • Turn on Air supply and adjust to calculated pressure (DO NOT EXCEDE 100psi) • If table does not float within 5 minutes, slowly increase pressure or adjust valve height adjustment screw to hold the control arm down further. Be sure metering needle valves are open. • If table oscillates reduce pressure and/or close needle valve slightly Table height sensor Control arm Metering needle valve
