33. Clean the gasket and quad ring thoroughly with a clean,
dry rag. Do not return the gasket and quad ring to the
fill cap in a completely dry state. Instead, apply a coat of
silicone grease. Spread the grease lightly and evenly on
the gasket surfaces. A thin coating is all that is required
to eliminate seizing and stretching which could be experi-
enced with a dry gasket.
34. Return the gasket and quad ring to fill cap, taking care
not to twist the quad ring as it is returned to its recess in
the cap.
35. Use a stiff bristle brush to clean dry chemical from the
threads or top collar gasket seating surface of the shell.
36. Reinstall and retighten the fill cap, until flat gasket makes
contact with the cover. Over-tightening using a bar or
similar leverage may result in mechanical injury to the fill
cap, especially to the threads.
37. Lift the puncture lever, place the hose behind the lever.
With the puncture pin fully retracted and the hose in place
to prevent the lever from being depressed, the cartridge
may now be installed.
38. Apply silicone grease to external threads of ANSUL
cartridge and install in the receiver (hand tighten) and
carefully engage the cartridge guard.
“E” Model (Metal cartridge guard) –
Align the guide fork
with the recess in the cartridge receiver body and push
straight on. Secure the nozzle in the holder. Proper align-
ment is especially important on ring pin models where the
pin is inserted through the cartridge guard and puncture
lever link located immediately below the puncture lever.
“G” Model (Composite cartridge guard) –
On extin-
guishers with the composite guard, the hose must be
carefully lifted from the area behind the puncture lever,
the guard pushed into place, and then the hose reposi-
tioned again behind the puncture lever. Hold the puncture
lever up while replacing hose behind lever. Make certain
puncture lever is not accidentally pushed. Secure nozzle
in holder.
