Close all valves and handles of the pump, and tighten the plugs
on the connectors during transportation.
Always keep the reservoir cover vent valve #4 open during
operation.
（ ）
Do not over tighten the valves, connectors and handles to avoid
any 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.
Any security problems or damages caused by incorrect operations
are beyond Additel's responsibility.
Troubleshooting
Hard to pressurize
through turning
Pre-pressurization
handle (#9)
Problems Causes Solutions
Hard to pressurize through
turning high-pressure
pressurization handle (#8)
Hard to reach high vacuum
Hard to turn the
valves or handles
Step 1: Turn pre-pressurization handle (#9) clockwise fully, close pre-pressurization shut off valve (#7),
open reservoir shut off valve (#1).
Step 2: Turn pre-pressurization handle (#9) anticlockwise fully, close reservoir shut off valve (#1).
Step 3: Open pre-pressurization shut off valve (#7), pressurize the system.
Step 4: Repeat step 1 to 3.
Reservoir shut off valve (#1) is not closed
The media is not enough
The pre-pressurization shut off valve (#7) is not closed completely
The connector of DUT is not matched to connector
Pre-pressurization shut off valve (#7) is closed
Too much air in the pump
Reference gauge or devices under test (DUTs) are not connected tightly
Hard to pressurize
large-cavity DUT
Close shut off valve (#1)
Fill more media, and keep media level between 1/4 and 3/4 of the liquid reservoir filled
Close pre-pressurization shut off valve (#7)
Use proper adapter
Open pre-pressurization shut off valve (#7)
Turn the handle anticlockwise to vacuum the pump, open reservoir shut off valve (#1) to have air released
Check connector, replace the PTFE type, re-tight using a wrench
Close pre-pressurization shut off valve (#7), open reservoir shut off valve (#1), turn pre-pressurization handle
(#9) clockwise fully, close reservoir shut off valve (#1), and then open pre-pressurization shut off valve (#7)
Do not close shut off valves and handles too tightly
Lubricate the threads
It is normal. Please use high-pressure pressurization handle to increase/reduce the pressure.
Too tight in last operation
Lack of lubrication on threads
Hard to turn pre-pressurization handle (#9) at high pressure
Large-cavity of DUT, and pressurize the system too slow
Too much air in the pump
Always tighten the gauges using two wrenches .

#4 valve is not open Open the #4 valve
Pressure gauges do not
reach to zero
Remark： . If local atmosphere pressure is 1 bar, the vacuum can reach to 0 85 bar;
If local atmosphere pressure is P, the vacuum can reach to bar. ( P 85% )
#4 valve is not open Open the #4 valve
When the system pressure is greater than ,
the re-pressurization shut off valve（#7）
pressurize the system.
10,000 psi you must
close p and then
