Maintenance
General inspection
Initiate a flush cycle by closing the 1/4" valve at the low pressure sensing port of the pressure differential switch for 5 seconds. Check
that the exhaust valve opens, that the scanner moves properly, and when it reaches the limit switch - verify that the exhaust valve closes.
Weekly maintenance:
1. Check that the filter operates properly, following a general inspection.
2. Clean the 3/4" filter (close the 3/4" valve and operate a flushing cycle in order to release pressure and then open the bowl).
3. Check that there is grease on the drive shaft, and drive bushing. Add grease if necessary.
4. Take care of any leakage from the scanner shaft. If necessary, tighten the sealing nut (17 on page 24) or replace the sealing nut
internal O-ring (18 on page 24)
Changing the sealing nut internal O-ring:
1. Close the inlet valve to the filter and release the pressure.
2. If the Suction Scanner is in the outer position, operate a flushing cycle and bring it to the inner position.
3. Remove the Split pin (13) and pull out the connecting pin (12).
4. Operate a flushing cycle.
5. Stop the motor operation when the drive shaft reaches half way of its movement. The drive shaft is now separated from the
Suction Scanner.
6. Unscrew the sealing nut (17 on page 24).
7. Remove the used internal O-ring and clean the O-ring seat.
8. Insert a new O-ring (18 on page 24)
9. Tighten the sealing nut (17 on page 24).
10. Re-connect the drive shaft to the suction scanner shaft.
11. Operate the control board and open the filter inlet valve.
Maintenance prior to long term shutdown (end of season):
The following must be done if the filter will not operate for more than a month.
1. Operate flushing cycle (If possible, with a closed downstream valve).
2. Disconnect the control board from the power.
3. Release pressure from the filter.
4. Grease the drive shaft and the drive bushing.
5. Clean the 3/4" control filter.
6. Clean the coarse screen through the service port.
Maintenance prior to renewing filter operation:
1. Connect the control board to the mains.
2. Check proper operation of the filter.
3. Grease the drive shaft and the drive bushing.
4. If necessary change the sealing nut internal O-ring.
IMPORTANT!!
THE DRIVE SHAFT MUST BE LUBRICATED WITH HEAVY-DUTY, WATER RESISTANT GREASE THAT WILL NOT OXIDIZE. (SHELL, DARINA
EP-2 OR SIMILAR).
