SHUTDOWN
To remove the filter from operation, reverse the steps used for startup.
1. Close the outlet valve.
2. Open the bypass valve
3. Close the inlet valve, and slowly open the drain valve on the bottom of the
filter housing. There will be residual pressure in the tank still, so use
caution when draining.
If it is not possible to close the outlet valve momentarily before opening the
bypass, then both may be actuated simultaneously.
PERIODIC MAINTENANCE
Every six months to a year, or during scheduled down-time it is recommended to
open the filter and inspect the components. Access to the internal components is
through the front cover and hydraulic motor chamber.
Remove the piston from the back filter and drain the water from the hydraulic
motor chamber. Verify that the piston rod is moving smoothly in and out, and
inspect the piston tip for wear.
C+ SERIES FILTER - PERIODIC INSECTION
Remove the hydraulic motor from the rest of the particle remover by accessing it
through the piston-side cover.
Remove the screen and particle remover, using the piston-side cover for access.
Separate the two items and inspect them carefully. The screen mesh and
bushing should be inspected for wear, as well as the particle remover rod and
suction nozzles.
