Additel ADT 949 Operating Manual

Warningsand cautions

Operate the pump in the rated pressure range of 40,000 psi (2,800 bar)
and do not exceed the safety pressure of 44,000 psi (3,080 bar).
When the system pressure is greater than 10,000 psi, you must close the
pre-pressurization shut off valve（#7）and then pressurize the system with
the high pressure handle.
Always tighten the gauges using two wrenches .
Close all valves and handles and tighten the ports when transporting the pump.
Always keep the reservoir cover vent valve（#4）open during operation.
Do not over tighten the valves, connectors and handles to avoid damage.
Change media immediately if it is contaminated.
Keep media level between 1/4 and 3/4 of the liquid reservoir filled.
Keep the threads clean and lubricious, and remove any dirt on threads.
Used by trained personnel only.
Additel is not liable for any safety problems or damages caused by misuse
or incorrect operation.

Problem

Vent (#1) is not closed

It is difficult to generate

pressure with the

pre-pressure

handle (#9)

It is difficult to pressurize by

turning the high-pressure

handle handle (#8)

It is difficult to generate

high vacuum

Hard to pressurize

large-volume DUT

Pressure gauges do not

reach to zero

Hard to turn the

valves or handles

O-Rings for pressure connector

1611300220

Pre-pressure shut off valve (#7) is closed

Not enough media is in the reservoir.

Too much air is in the pump

Max pressure generation (could be as low as 5,000 psi, 350 bar) is
achieved with the pre-pressure handle (#9)

The pre-pressure shut off valve (#7) is not closed completely

Reference gauge or devices under test (DUTs) are not connected tightly

The connector of the DUT is not matched to connector

Too much air is in the pump

#4 valve is not open

Because of the large volume of the DUT, it will take additional steps to
fill the volume to pressurize the DUT

#4 valve is not open

Too much force was previously applied

Hard to turn pre-pressure handle (#9) at high pressure

Lack of lubrication on threads

P/N

Cause

Solution

Close vent valve (#1)

Open pre-pressure shut off valve (#7). Caution: the pre-pressure side of the pump should not be exposed to
more than 10,000 psi (700 bar).

Fill more media, and keep media level between 1/4 and 3/4 of the liquid reservoir filled

Purge the air from the system (see Preparation section of the manual)

Close pre-pressure shut off valve and use high-pressure and handle (#8).

Close pre-pressurization shut off valve (#7)

Check finger-tight connectors, re-tight if necessary

Use proper adapter

Purge the air from the system (see Preparation section of the manual)

Open the #4 valve

Step 1: Turn pre-pressure handle (#9) all the way in clockwise, close pre-pressure shut off valve (#7),

open vent valve (#1).
Step 2: Turn pre-pressure handle (#9) all the way counterclockwise, close vent valve (#1).
Step 3: Open pre-pressure shut off valve (#7), pressurize the system.
Step 4: Repeat step 1 to 3.

Open the #4 valve

Do not over tighten

This is normal. Close the pre-pressure shut off valve (#7) and use the high-pressure handle to adjust the
pressure.

Lubricate the threads

the third connector on pump should be closed with a plug.

② Connect the gauges on pump and tighten the connectors using two wrenches.
