5. Operation The CA44(S) and CA46(S) float traps are continuous discharge traps, removing liquid from air and gas systems. As soon as liquid enters the main chamber of the trap, the float rises and the lever mechanism attached to it opens the main valve - keeping the system drained of liquid at all times. - Page 11 Air receiver Balance line Strainer CA14 air trap draining small receiver Fig. 5 Installation with balance line arrangement IM-P148-37 ST Issue 3...

Undo the cover bolts (2) and lift off the cover. Remove the float assembly (8 + 9 CA44 and CA46 only) by extracting the pivot pin (16). Remove the support (14), pivot frame (15) and the valve seat (5) by unscrewing the set screws (7). - Page 13 Fig. 6 CA44S and CA46S DN40 and DN50 Note: The trap shown is the DN40 and DN50 CA44S / CA46S. However the type of internals and the method of maintenance is no different from that used in the smaller sizes of CA44(S) and CA46 (S).
