APOLLO DISC-KLEEN FILTER OPERATIONS, MAINTENANCE AND TROUBLESHOOTING GUIDE
GENERAL REQUIREMENTS AND MAINTENANCE:
• Confi rm there is 30 psi of pressure downstream of the fi lter during backfl ush.
• Check that the Pressure Differential (PD) Gauge returns to 0-2 psi after a
backfl ush.
• All vent tubes need to vent freely to atmosphere without any back pressure.
• To minimize damage to the backfl ush controller, always keep the door closed
and turn off the power when not using the controller for long periods of time.
SEASONAL MAINTENANCE:
• At the end of the irrigation season, just before shutdown, initiate a backfl ush
with the required pressure and turn off the water. This will ensure the discs
remain clean during the offseason.
• Manually clean the discs if needed – see detailed instructions on Page 11.
• In order to prevent the fi lter from becoming damaged under freezing
conditions, drain all the water from the fi lter and leave the drain valve open.
Disconnect the hydraulic tubes from the PD Gauge.
START-UP OPERATION:
• Flush out the main line upstream of the fi lter by opening
the blind fl ange connection of the inlet manifold. After
initial fl ushing, reassemble the blind fl ange.
• Turn the system on slowly to build up the pressure.
• Start the backfl ush cycle making sure that all system
components function correctly.
• Check that the PD gauge reads zero after a backfl ush
cycle.
IF FILTER LOADS UP DURING START-UP:
• Close the downstream (fl ow control) valve to increase
pressure downstream of the fi lter.
• Initiate
backfl ush cycle until the discs are clean.
• Slowly reopen the downstream valve.
• If the pressure difference remains high, check and see if
the fl ow rate is too high. An excessive fl ow rate through
the fi lter causes excessive pressure loss.
