pump head are secure before removing any tubing from the
pump head.

4. Remove the outlet line from the outlet check valve.
5. Remove inlet and outlet self-flush check valves.
6. Momentarily turn ON the Binary pump and quickly turn OFF the
power upon hearing the refill stroke. This reduces the extension of the
piston and decreases the possibility of piston breakage.

CAUTION: Use care when removing the pump head.
Twisting the pump head can cause the piston to break.

head straight out from the pump and remove it from the piston. Be
careful not to break or damage the piston. Also remove the seal and
seal backup washer from the piston if they did not stay in the pump
head.
10. Carefully separate the flush housing from the pump. Move the flush
housing straight out from the pump and remove it from the piston. Be
careful not to break or damage the piston. Also remove the self-flush
seal from the piston if it did not stay in the flush housing.
