5. Maintenance The PN3000 and PN4000 series pneumatic actuators are maintenance free. To ensure satisfactory operation it is strongly recommended that the control signal air is filtered and supplied free of oil and water. Should it be necessary to replace spare parts the following procedure should be used. Removing Actuator from Valve Drive actuator into approximately mid-travel position with the air supply. - Page 17 PN4000 Series 5.3.1 Diaphragm Kit - How to Fit Remove actuator from valve as described in Section 5.1. Loosen and remove housing screws (16) and remove housing lid (1), as described in Section 5.2.1. Using two spanners whilst holding actuator spindle (5), loosen plate locknut (6). Remove diaphragm clamp (10) and diaphragm (2).
