Configuration & Air routine

Under Vacuu

Troubleshooting

Problem

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

917/918

[Version number:1407V02]

1 - Hand pump

2 - Transport handle

3 - Quick connector

4 - Vent valve

（clockwise to close/ counterclockwise to open）

5 - P/V selector lock

6 - Pressure/vacuum (P/V) selector

（

Positive pressure: pull it out; vacuum: push it in

DO NOT switch under pressure or vacuum to

avoid damage）

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）

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

A. The isolation valve is not closed

B. The gauges are not tightened.

C. The O-ring seal is damaged.

D. The thread surface is not smooth.

E. The connector type mismatched to the gauge pressure port.

F. Dust or contaminants are blocking the pressure flow

A. Too much force was previously applied.

B. The threads have no lubrication

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.

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.

Open the isolation valve

Close the vent valve.

Replace O-ring seal

Pressure: pull the P/V selector out; Vacuum: push the P/V selector in.

Close the isolation valve

Tighten the reference gauge or the gauge under test

Replace the O-ring seal.

Use Teflon tape on the thread and turn it in tight

Use the correct adapter

Pressurize the pump several times and then suddenly vent which will push any

contaminants out.

Secure the quick connect valves with less force.

Apply lubrication to the threads
