10 Care for and maintain the ED12 pressure
regulator
Servicing the ED12 pressure regulator
No special care is required for the ED12 pressure regulator.
Damage to components!
Solvents and aggressive detergents will destroy the surface, labeling and seals
of the device!
O Only clean the device using a slightly damp cloth. Only use water to do this
and, if necessary, a mild detergent.
Danger of burns caused by hot coils!
Touching the valve coils during operating may lead to burns.
O Let the device cool off before disassembling.
O Do not touch the device during operation.
O Check that all seals and plugs for the plug connections are firmly fitted so that no
humidity can penetrate the ED12 pressure regulator during cleaning.
Maintaining the ED12 pressure regulator
The ED12 pressure regulator is maintenance-free.
O However, the system-specific maintenance intervals must be observed.
Check the ED12 pressure regulator seals
The seals in the ED12 pressure regulator may age faster under aggressive ambient
conditions. Defective seals will lead to pneumatic leaks and non-compliance with the
IP65 protection class.
O Every now and then, check that the seals on the pressure regulator are in perfect
order.

11 If Malfunctions Occur

present
No set point stipulated
No supply pressure
available
Outlet pressure too
Supply pressure too low
low
Outlet pressure less
Consumers that use a lot
than the set point
