Additel 920 User Manual
Warningsand cautions
Low pressure gauges can very easily be over pressured if not careful.
Please take caution when applying pressures.
Do NOT exceed the safety pressure limit ( 3500 psi / 235 Bar ).
This pump is not designed to be used in explosive or corrosive environments.
Do not switch between pressure and vacuum mode under pressure. Make sure you
have vented the pressure and opened the isolation valve before switching to vacuum.
Over tightening connectors may cause damage.
Pump should be stored in a dry/clean environment.
Additel is not liable for any safety problems or damages caused by misuse or
incorrect operation.
Do NOT hold pressure above 1000 psi for more than 4 hours.
All moisture and contaminants should be cleaned out of the liquid isolator before
creating a vacuum. This is accomplished by venting the pump when at high pressure.
For the least risk in contamination of the reference gauge, the DUT should be
installed to the pressure port which is closest to the vent valve.

Troubleshooting
Problem
Hand pump will not generate pressure
It is difficult to increase pressure
Hard to use fine adjust
Not easy to turn fittings
Cause
The isolation valve is not open
A. Vent valve is not closed.
B. The O-ring seal is loose or damaged
C. P/V selector is in the wrong position
D. Internal tubing is dirty.
A. The isolation valve is not closed.
B. The gauges are not tightened.
C. The O-ring seal is aged or frayed.
D. The connector type is mismatched to the gauge pressure port.
E. Air route is blocked/dirty
A. Too much force was previously applied.
B. The threads have no lubrication
C. The connector type is mismatched to the gauge pressure port.

Solution
Open the isolation valve
Close the vent valve.
Replace O-ring seal.
Pressure : Pull P/V selector out; Vacuum : Push the P/V select or in.
Disassemble and clean (Request diagram).
Close the isolation valve.
Tighten the reference gauge and / or the gauge under test
Replace O-ring seal.
Use the correct adaptor.
Pressurize to high pressure and release pressure quickly via the vent valve
Do not over tighten. Hand tight is sufficient.
Lubricate the thread
Use the correct adaptor.
