Disassembling the Separator / Main Valve Section
Turn the
PN-COS-16
upside down for easy dismantling of the separator and main
valve. Loosen the hex bolts and remove the trap body. Be careful, as the separator
may drop off when the
PN-COS-16
is returned to the normal attitude.
Removal of the separator and pressed-in sleeve permits removal of the main valve,
main valve holder, main valve spring and separator screen.
Loosen the main valve seat with a socket wrench and remove it from the main body.
Check for damage on the seating surfaces of the main valve and main valve seat,
gaskets, and sliding surfaces of each part, and for clogging of the separator screen.

Loosen the hex bolts (for the trap cover)

reveal the float. Remove the float, then
loosen the trap valve seat with a socket
wrench and remove it.
Check to determine that there is no

the trap valve seat or dirt accumulation
in the trap cover.
