Additel 918 Pneumatic Pressure Test Pump User Manual - Manual

Pneumatic Pressure Test Pump User Manual 's
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
Remark： If local atmosphere pressure is 1 bar, the vacuum can reach to -0.95 bar;
If local atmosphere pressure is P, the vacuum can reach to - 0.95P.

Air routine
1 - Hand pump
2 - Transport handle
7 - Isolation valve (Bypass valve)
(Isolated the calibration volume from the hand pump,
piston, and check valve)
8 - Fine adjust handle
（clockwise to increase pressure）
6 - Pressure/vacuum (P/V) selector
（
DO NOT switch under pressure or vacuum to
avoid damage）
Positive pressure: pull it out; vacuum: push it in
5 - P/V selector lock
4 - Vent valve
（clockwise to close/ counterclockwise to open）
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 connector
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 type 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 O-ring seal
Close the isolation valve
Use the correct adapter
Secure the quick connect valves 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
Pressurize the pump several times and then suddenly vent which will push any
contaminants out.
Apply lubrication to the threads
