c. The inlet assembly can now be disassembled by using a small flathead

screwdriver to unscrew the inlet valve (VRA-112) from the vent plug (VRA-111).

Be careful when disassembling as the inlet assembly is under spring tension and

small parts could be lost.

d. Once the inlet valve, vent plug, spring, spring holder and spring retainer are

removed, the seal plug (VRA-182) and inlet capsule (VRA-141) can be

unscrewed.

e. The inlet valve seat (VRA-110) can be removed by pressing it up and through

the inlet capsule. The inlet valve seat is a maintenance part and once removed

should never be reused.

f. Carefully clean the inlet capsule, seal plug, inlet valve stem, vent plug, spring

holder, spring retainer and spring. NOTE: The VRA-112 inlet valve stem must be

cleaned using a non-abrasive cloth (or Scotch-Brite pad).

g. Using a new inlet valve seat and new o-rings (with a thin film of the grease

provided on each o-ring), reassemble the inlet assembly in reverse order.
