MAINTENANCE

This section describes how to maintain the Waterfall
Cleaning the Pump Strainer Basket
The strainer basket in the pump should be visually inspected at least once a week. Remove the clear lid and the
basket and clean debris from basket. Inspect the lid o-ring; if damaged replace. The pump seal requires no lubrication.
DO NOT open the strainer pot if pump fails to prime or if pump has been operating without water in the strainer
pot. Pumps operated in these circumstances may experience a build up of vapor pressure and may contain
scalding hot water. Opening the pump may cause serious personal injury. In order to avoid the possibility of personal injury, make
sure the suction and discharge valves are open and strainer pot temperature is cool to touch, then open with extreme caution.
To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and
skimmer baskets regularly.
1. Turn off the pump at the breaker.
2. Close the inlet and discharge valves.
3. Relieve pressure in the system.
4. Turn the strainer lid in a counter-clockwise direction to remove the lid and
remove the basket from the pump.
5. Remove the debris from the strainer basket and rinse out the basket.
Replace the basket if it is cracked.
6. Replace the basket.
7. Fill the pump strainer pot and volute up to the suction/inlet port with water.
8. Clean the lid, O-ring, and sealing surface of the strainer pot.
Note: It is important that the O-Ring be kept clean and well lubricated.
9. Reinstall the lid by placing the lid back onto the strainer pot and turning the
lid clockwise.
Note: Be sure the lid O-ring is properly placed around the entire sealing
surface of the strainer pot.
10. Open the inlet and discharge valves.
11. Turn the power "ON" at the circuit breaker.
THIS SYSTEM OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system (e.g., Lock Ring,
Pump, Filter, Valves, etc.) is serviced, air can enter the
system and become pressurized. Pressurized air can
cause the lid to separate which can result in serious
injury, death, or property damage. To avoid this potential
hazard, follow these instructions.
12. Open the manual air relief valve on top of the filter.
13. Stand clear of the filter. Start the pump.
14. Bleed air from the filter until a steady stream of water comes out. Close the manual air relief valve.
