Additel 916 User Manual

Warningsand 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 ( 0 bar).

7

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

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

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..

.

.

Solution

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

Repeat pressurizing 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..
