PRESSURE RELIEF/WORK INTERRUPTION

The pressure must always be relieved:
− after the spraying tasks are finished,
− before servicing or repairing the system,
− before carrying out cleaning tasks on the system,
− before moving the system to another location,
− before something needs to be checked on the system,
− before the nozzle or the filter is removed from the spray gun.
The components for pressure relief on a CE-compliant spraying system include:
− Outlet equipment (return valve) mounted between pump and spray gun.
Process for relieving pressure
1. Close the product delivery valve or any other device installed on the delivery line
(such as outlet valves or spray guns).
2. Close the air cut-off valve. Relieve the pressure in the product line, by opening the
return valve (if installed) or the dispensing device (valve or spray gun).
3. Close and secure return valve and dispensing device.
Note:
Control air pressure is still present.
If the system will process 2K products:
NOTICE
Hardened working material in the spraying system when 2K product is processed!
Destruction of pump and injection system.
Observe the manufacturer's processing rules, particularly in regards to the pot life.
Flush thoroughly before the end of the pot life.
The pot life is decreased by warmth.
