Warnings and 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 of 1000 psi (70bar).
This pump is not designed to be used in explosive or corrosive
environments.
Do not switch between pressure and vacuum mode under pressure.
Over tightening connectors may cause damage.
Store the pump in dry and non-corrosive environments.
Additel is not liable for any safety problems or damages caused by
misuse or incorrect operation.
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
Solution
Cause
Hand pump will not generate pressure The isolation valve is not open.
Open the isolation valve.
A. Vent valve is not closed.
Close the vent valve.
It is difficult to increase pressure B. The O-ring seal is loose or damaged.
Hard to use the fine adjust
It is difficult to turn the quick connectors
Replace the O-ring seal.
C. P/V selector is in the wrong position.
Pressure: pull the P/V selector out; Vacuum: push the P/V selector in.
A. The isolation valve is not closed.
Close the isolation valve.
B. The gauges are not tightened.
Tighten the reference gauge or the gauge under test.
C. The O-ring seal is damaged.
Replace the O-ring seal.
D. The thread surface is not smooth.
Use Teflon tape on the thread and turn it in tight.
E. The connector is mismatched to the gauge pressure port.
Use the correct adapter.
F. Dust or contaminants are blocking the pressure flow
Repeat pressurizing the pump several times and then suddenly vent which will push any contaminants out.
A. Too much force was previously applied.
Secure the quick connection with less force.
B. The threads have no lubrication.
Apply lubrication to the threads.
