19. Ensure the actuator is correctly aligned and located within the slots of the pump bracket (item 13).
20. Once this is correctly located, ensure the exhaust valve can slide easily within its guides.
21. Always use new split pins and washers when refitting the spring retaining shaft (Y) (30 mm long).
22. Check that the mechanism snaps over and opens and closes the valves by moving the float
to its upper and lower limit of travel.
Note: The valve gear has been designed to be adjustment-free, simplifying the fitting of new
parts. If after assembly the mechanism does not operate correctly, check all the parts are
assembled and aligned as per Fig. 25.
23. With the mechanism fully assembled, refit the cover assembly to the body, ensuring the gasket
faces are carefully aligned and no parts of the gasket are trapped or pinched outside the sealing
areas.
24. Refit the cover bolts ensuring they are sequentially tightened in opposing pairs, gradually
increasing torque to 63 ± 5 N m (46.5 ± 4 lbf ft).
25. Carefully reconnect the motive steam supply and the exhaust lines to the connections
marked (S) and (E) and the condensate inlet and outlet to the connections marked (IN)
and (OUT). The APT10-2 is now ready to recommission.
