7. CHANGING MIX RATIO
The PU 2125 F pump features a fixed ratio proportioning system (ratio : 1/1, 2/1, 3/1, 4/1, 5/1 according to
the choice of the CATA fluid section).
To change the ratio, the CATALYST fluid section must be changed with a fluid section of a different ratio
(refer to PU 2125F spare parts' list).
8. SHUTDOWN AT THE END OF WORK
COMPLETE FLUSHING : ONLY for material / color change or long duration shutdown.
Carry out a partial flushing (refer to § 5).
Empty the CATALYST container - replace CATALYST with CLEAN solvent.
Insert SOLVENT suction rod into a container of CLEAN solvent.
Remove gun aircap and clean it.
Place the valve (11) hand lever vertically.
Connect the air tube on the hole on the far left of the
plate (
⇒
opening of the CTM valve towards the AR
valve).
Adjust the black regulator to 2 or 3 bar / 29 or 43.5 psi.
Point the gun into a waste container and make the fluid flow out until you get solvent.
Remove and clean the mixer (15).
Remove and clean the CATA tank screen after having emptied the tank content.
To get a perfect flushing, repeat this procedure twice using some CLEAN solvent.
Install the aircap onto the gun.
Shut off the main air supply.
Leave the pump filled with clean solvent.
9. DAILY CARE
SPRAY GUN
Comply with the usual instructions of spray gun servicing (refer to spray gun instruction manual).
PUMP
Make sure the wetting cup of the BASE fluid section is filled up with T lubricant. Fill if necessary (level :
3/4 of the cup).
Regularly change the lubricant (this lubricant will normally be coloured by the paint). Make sure the
wetting cup is clean and regularly clean it with solvent after having drained the lubricant.
Make sure the suction strainers and rods are clean and in good condition.
Check the hoses.
Flush the pump as often as necessary.
Never inject oil into the compressed air supply.
The CATALYST tank is fitted with a screen. Clean that screen regularly or change it, if necessary
(filtration size : 50 MESH)
When stopping the pump, always leave it filled up with material.
For a short duration, if the flushing has not been carried out, leave the pump filled up with
material.
For a long duration, after flushing the pump, leave it filled up with solvent.
Before cleaning or removing a component of the equipment, you must :
1 - stop the pump compressed air supply,
2 - place the manifold valves in 'circulation' position,
3 - trigger the gun to depressurize the hoses.
