Observe the following instructions on installing the pneu-
matic components. Only then can you guarantee faultless
operation.
– If you have several systems with central ducted exhaust
air, use non-return valves in the common exhaust lines in
order to prevent functional impairment due to back
pressures.

– In the case of CPA valve terminals with two or more pres-

the right-hand side, the pressure for the pressure zone on
the outside right must be 3...8 bar.
