mixing unit. Install, instead of it, the fitting (25) and the
needle-valve assembly (19) supplied with the machine.
Take off the control air hose on the VP2A BASE valve.
Connect that hose to the VP3 valve. The VP3 valve is
originally supplied with a needle valve assembly (19).
Pass in F 5 mode to adjust the opening of the needle-
valves. Prime the A pump and adjust the
opening of the needle-valve.
Prime the B pump and adjust the
opening of the needle-valve.
Place the beakers underneath the valves. Start up the PU
3000 pump, then open the valves.
Input
The PU 3000 passes in test mode and displays
Caution : the fluid pressure must be lower than
200 bar / 2900.6 psi.
The BASE and CATA materials are dispensed into the
beakers. After a while, close the needles' valves and check
the ratio.
Activate ESC to stop the test and only after that you can
removing the test outlet.
Nota : During that stage, you can not use the spray gun. Nota : design of a pump,
model PU 3000 Airmix 
When the mixing ratio checking is over, switch off the PU 3000 machine.
Disconnect the air hose from the VP3 valve and connect it to the BASE valve.
Remove the needle-valve assembly (19) and the fitting (25). Screw again the fluid hose on the fitting
(M 3/4 JIC) at the outlet of the mixer unit.Start up the machine.
Wear protective glasses to protect the eyes from possible discharges during the handling
of the valves.
Flush the needle valve assembly that has been removed and do not leave the catalyst
crystallize : - Flush the CATA test outlet : input F2 to carry out the flushing. When it is
clean, activate ESC.
- Flush the BASE test outlet : invert the test outlets and carry out a flushing
until it is clean.

9. APPLICATION PROGRAMMING (F3)
To alter the parameters of the PU 3000, go to F3, then validate. To shift from a parameter to another, use
the arrows or .
Select the parameter to alter. Depress the key OK , then the arrows or to increase or decrease the
value. Activate OK to validate the new value or ESC to cancel.
To quit a parameter, activate ESC.
To quit the PARAMETERS menu, activate ESC.
The parameters are pre-set up in the factory. They must be adjusted (by an authorized person) to suit the
material to be processed.
The calibration of the stroke length is carried out in the factory. When removing the movement
sensors or when disassembling the fluid section from the motor, it is important to initialize the pumps
(refer to P10).
PASSWORD
When you start the machine for the first time the access code of the menu `Parameters' is
deactivated, everyone is able to modify the machine’s parameters.
To activate this access code you have to :
- enter in the parameter 0 of the menu F3 : « key » « key ».
The code ‘’appears, it’s the code present by default in the machine.
- change the code by using the arrows or and the «key » for each digit which compose this
code.
Once the access code was validated, the access is protected by the password. Only the people who
know this password and those which know the administrator code ‘’will be able to reach the
menu `Parameters'.
Each time a user wants to enter in the menu 'Parameters' the password will be required: .
The user shall enter the password by using the arrows or and the «key » for each digit
which compose this code :
- If the entered code is correct, the following fonts appear.
- If the entered code is incorrect, the word ‘appears and the machine allows you to enter the
password again (Press 'Esc' to return to the principal menu).
If you want to desactivate the password, you just have to parameterise the code ‘’again as
access code.
