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 limit of 1500 psi (100 bar) for 917 or
2000 psi (140 bar) for 918.
Do not switch between pressure and vacuum mode under
pressure. Open the vent valve and isolation valve before
switching between positive to vacuum pressures.
Over tightening connectors may cause damage. Light hand
tightening is sufficient.
Store the pump in a dry non-corrosive environment.
Additel is not responsible for problems or damage resulting from
improper use or operation of the equipment.
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 the fine adjust
Solution
Cause
The isolation valve is not open.
Open the isolation valve.
A. Vent valve is not closed.
Close the vent valve.
B. The O-ring seal is loose or damaged.
Replace 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 type mismatched to the gauge pressure port.
Use the correct adapter.
F. Dust or contaminants are blocking the pressure flow
Pressurize the pump several times and then suddenly vent which will push any
contaminants out.
It is difficult to turn the quick connector
A. Too much force was previously applied.
Secure the quick connect valves with less force.
B. The threads have no lubrication.
Apply lubrication to the threads.
