Pressure Relief Procedure | Flushing |
Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.
1.Shut off the air to the pump.
2.Close the
3.Hold a metal part of the dispense valve firmly to a grounded metal pail. Trigger the valve to relieve pressure.
4.Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to dispense again.
5.If you suspect the nozzle or hose is clogged or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen the hose end cou- pling to relieve pressure gradually, then loosen completely. Clear hose or nozzle obstruction.
Flush Pump Before Use
The pump is tested with lightweight oil, which is left in to protect the pump parts. To prevent contamination of the fluid you are pumping,
flush the pump with a compatible solvent before using it. See Flushing, page 13.
• Flush at the lowest pressure possi- ble. Check connectors for leaks and tighten as necessary.
•Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.
Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.
1.Follow Pressure Relief Procedure, page 13.
2.Place suction tube in grounded metal drum containing cleaning fluid.
3.Set pump to lowest possible fluid pressure, and start pump.
4.Hold a metal part of the dispense valve firmly to a grounded metal pail. Trigger the dispense valve until clean solvent dis- penses.
5.Remove valve from hose.
6.Follow Pressure Relief Procedure, and remove fluid filter and soak in solvent. Replace filter cap.
7.Cycle the pump slowly for at least 5 min- utes, then stop and disconnect the air hose.
8.Push up on the ball (5) of the intake valve (29) to drain the lower part of the pump.
