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
2 - Vent valve
clockwise to close/ to open） （ counterclockwise
3 - Isolation valve
isolates the calibration volumn from pressurizing system） （
4 - Hand pump
5 - Fine adjust andle h
（clockwise to increase pressure）
6 - Security bolt pin
（use it to ensure safety）
7 - Pressure/vacuum (P/V) selector
Postive pressure: pull it out; Vacuum: push it in） （
Problem Cause Solution
Hand pump will not generate pressure
It is difficult to increase pressure
Hard to use the fine adjust
It is difficult to turn the quick connectors
The isolation valve is not open
B. The O ring seal is loose or damaged
A. The isolation valve is not closed
C. The O-ring seal is damaged.
E. The connector is mismatched to the gauge pressure port
A Too much force was previously applied
.
.
.
- .
. .
A. Vent valve is not closed.
C. P/V selector is in the wrong position
B. The gauges are not tightened.
D. The thread surface is not smooth
F. Dust or contaminants are blocking the pressure flow
B. The threads have no lubrication
.
.
.
Open the isolation valve
Replace the O ring seal
Close the isolation valve
Use the correct adapter
Secure the quick connection with less force
.
.
Replace the O ring seal
- .
.
.
- .
Close the vent valve.
Pressure pull the P V selector out; Vacuum push the P V selector in
Tighten the reference gauge or the gauge under test
Use Teflon tape on the thread and turn it in tight.
Repeat pressurizing the pump several times and then suddenly vent which will push any contaminants out
Apply lubrication to the threads
