1. Turn off the system pump(s).
WARNING
NEVER attempt to assemble,
disassemble or adjust the lter when
there is pressurized air in the system.

off, which can cause death, serious
personal injury or property damage.
2. Open the air release valve on top of the lter tank
to release all pressure from inside the tank and
system. Wait for all the air to evacuate the system.

handle is fully depressed (handle and piston
pushed all the way down). Turn the handle until
