Operation

Operation

Pressure Relief Procedure

1.Close the bleed-type master air valve (M).

2.Open the dispensing valve, if used.

3.Open all fluid drain valves (N) in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to pump again.

Prime the Pump

1.Fill the TSL reservoir to the Maximum fill line with Throat Seal Liquid (TSL). See FIG. 4 on page 13.

NOTE: During operation the TSL level in the reservoir will fluctuate slightly at pump changeover.

2.Close pump air regulator (L) by turning knob coun- terclockwise reducing pressure to zero. Close bleed-type air valve (M). Also verify that all drain valves (N) are closed.

3.Connect air line (J) to bleed type air valve (M).

4.Check that all fittings throughout system are tight- ened securely.

5.Connect the fluid supply line (C) from the mix tank shutoff valve (D) to the pump.

6.Connect the fluid line (E) to the pump outlet.

NOTE: If your pump has DataTrak, see your separate NXT air motor manual for DataTrak instructions.

7.Units with runaway protection only: enable the prime/flush function by pushing the prime/flush but- ton on the DataTrak.

8.Open bleed-type air valve (M). Slowly turn pump air regulator (L) clockwise, increasing pressure until pump starts.

9.Cycle pump slowly until all air is pushed out and pump and hoses are fully primed.

10.Units with runaway protection only: disable the prime/flush function by pushing the prime/flush but- ton on the DataTrak.

11.Verify that pump actuations are priming the pump wet-cup. If not, confirm that the TSL pump piston is being depressed at bottom changeover, and that reservoir check valves are not stuck closed.

12.Close the fluid shutoff valve (D) downstream of the pump. The pump should stall against pressure.

NOTE: In a circulation system, the pump operates con- tinuously until the power supply is shut off. In a direct-supply system, the pump starts when the dis- pense valve is opened, and stops when the dispense valve is closed.

Stop the Pump at the Bottom of Its Stroke

Relieve the pressure when you stop the pump for any reason. Stop the pump on the downstroke, before the air motor changes over.

NOTICE

Failure to stop the pump at the bottom of its stroke allows fluid to dry on the piston rod, which can dam- age the throat packings and the TSL pump piston seal when the pump is restarted.

Shutdown

Follow Pressure Relief Procedure, page 11.

Always flush the pump before the fluid dries on the dis- placement rod. See Flushing on page 12.
