PRESSURE RELIEF /
WORK INTERRUPTION
The pressure must always be relieved when:
− after the spraying tasks are finished,
− before servicing or repairing the spraying system,
− before carrying out cleaning tasks on the spraying system,
− before moving the spraying system to another location,
− before something must be checked on the spraying 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:
− Air cock with pressure relief hole mounted between compressed air source and
pneumatic pump.
− Outlet equipment (return valve) mounted between pump and spray gun.
Process for relieving pressure
1. Close the spray gun.
2. Close ball valve (2).
3. Release the system of pressure by opening the spray gun.
Attention: If a blocked nozzle is preventing relief, first carry out the additional steps
4 and 5, then clean the nozzle.
4. Close and secure the spray gun.
5. Open and close the return valve (3) slowly to completely depressurize the system.
If the system has been used with 2K products:
NOTICE
Hardened working product in the spraying system when 2K product is processed!
Destruction of pump and spraying 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.

BASIC FLUSHING
Regular flushing
Regular flushing, cleaning and maintenance ensures the pump's high conveying and
suction capacity.
The cleaning and flushing agents used must be compatible with the working
material.
Do not flush hardener pumps with water. Only flush them using suitable flushing
agents (solvents).
WARNING
Incompatibility of flushing / cleaning agent with the working medium!
Risk of explosion and danger of poisoning by toxic gases.
Examine the compatibility of the flushing and cleaning agents and working media
on the basis of the safety data sheets.
