Warningsand cautions
Operate the pump in the rated pressure range and do not exceed the
safety pressure of 15,000 psi (1,000 bar)
Close the valves and tighten the ports when transporting the pump.
Always open the reservoir release valve during operation.
Do not over tighten the connectors or handles to avoid any damage.
Change contaminated media immediately.
Do not let the media level get below the mid line of the reservoir when
the pump is place horizontal.
Keep the outer threads clean.
Additel is not liable for any safety problems or damages caused by
misuse or incorrect operation.

Troubleshooting
Problem
Difficult to increase pressure with
pre-pressurization handle
Hard to fine adjust
it is difficult to turn valves or quick
connectors
Cause
A. Vent valve is not closed.
B. The O-ring seal is loose or damaged.
C. Not enough media is in the reservoir.
D. The pump is not horizontal.
A. The vent valve is not closed.
B. The gauges are not connected tight.
C. The is aged or frayed.
sealing ring
D. The thread surface is not smooth
E. The connector type is mismatched to the gauge pressure port.
A. Too much force was previously applied.
B. The pre-pressurization handle may not adjust easily under high pressure.
C. The threads have no lubrication..
Solution
Close the vent valve.
Replace the O-ring
Fill with more fluid. Make sure fluid level is high enough after the
gas purging process.
Place the pump horizontally to prepare for pressure or vacuum.
Close the vent valve.
Tighten the gauges.
Replace sealing ring.
Use Teflon tape on the thread and turn it in tight.
Use the correct adapter.
Do not over tighten.
Adjust pressure by using fine adjustment handle. (Pressure may
need to be decreased with the fine adjustment handle before the
pre-pressure handle can be used).
Lubricate the thread.
