Cartridge Cleaning Procedure
When the filter gauge reading is 50 - 70kPa above the clean filter gauge reading, cleaning
the element cartridge is required. To perform the cleaning procedure:
1. Switch off the pump.
2. Close isolating valves on suction and discharge lines where fitted.
3. Open the air bleed valve on the filter lid, unscrew the lock ring and remove the filter lid.
4. Lift the element/s out.
5. In most cases the element can be easily cleaned with a garden hose, using good
velocity sprayed directly on the pleats.
NOTE: Algae, calcium, clay, sun tan oil and body oils can form a
coating on the element which may not be easily removed with normal
hosing. These materials can be removed by soaking the element in a
de-greaser and/or de-scaler. Your local Davey Dealer will be able to
recommend suitable products.
Failure to undertake regular maintenance may cause damage not
covered by warranty.
Cartridge Re-Assembly Instructions
1. Install the cartridge/s & centre pipe so that it is located in the bottom spigot.
2. Ensure the filter lid oring is clean, lubricated with oring lubricant and located in the
bottom groove of the lid.

sufficient - DO NOT OVERTIGHTEN.
4. Make sure the pump is primed according to manufacturer's directions.
5. Ensure all valves are open on suction and discharge lines.
6. Start the pump.
7. Close the air bleed valve when water is expelled.
