Atlas Copco Air Dryer CD 350+

During maintenance or repair on the regeneration valves, special attention must be paid to the connections of:

1. the pilot air hoses to these valves

2. the electric cabling between the valves and cubicle

Wrong connections may cause the working pressure to be fed to the regeneration silencer which may generate a high noise peak.

• Check that the dryer is switched off.

• Disconnect pressure sources and vent the internal pressure of the system before dismantling any pressurized component.

• Use original Atlas Copco spare parts only.

• Check for correct operation after maintenance

Service plan A, at least once a year
