2. Setup and Installation
Proper installation of the trap lid is crucial for preventing leaks and ensuring optimal pump performance. Please follow these steps carefully.
- Safety First: Before beginning any work on your pool pump, ensure the pump is turned off and disconnected from its power source to prevent electrical hazards.
- Remove Old Lid: Carefully unscrew and remove the existing trap lid from your Pentair Sta-Rite Dynamo pump.
- Inspect O-Ring: The new Pentair Trap Lid does not include an O-ring. It is essential to either transfer the O-ring from your old lid or install a new, compatible O-ring (sold separately). Inspect the O-ring for any cracks, tears, or signs of wear. A damaged O-ring will cause leaks. Ensure the O-ring is clean and properly seated in the groove around the pump's trap housing.
- Clean Sealing Surface: Clean the sealing surface of the pump's trap housing to remove any debris, dirt, or old lubricant that could compromise the seal.
- Install New Lid: Place the new Pentair Trap Lid onto the pump's trap housing, aligning it correctly. Screw the lid on clockwise until it is hand-tight. Do not overtighten, as this can damage the lid or the pump housing.
- Check for Leaks: Reconnect the pump to its power source and turn it on. Observe the lid area for any signs of water leaks. If a leak occurs, turn off the pump, disconnect power, and re-check the O-ring placement and lid tightness.
3. Operating Instructions
The Pentair Trap Lid functions as a secure cover for your pump's strainer basket. Its operation is straightforward:
- Ensure the lid is always securely hand-tightened before operating the pump.
- The transparent design allows for visual inspection of the strainer basket without removing the lid. Monitor the basket for debris accumulation.
- To access the strainer basket for cleaning, always turn off the pump and disconnect power before unscrewing the lid.
4. Maintenance
Regular maintenance of your trap lid will extend its lifespan and ensure efficient pump operation.
- Regular Inspection: Periodically inspect the lid for any signs of cracks, discoloration, or damage. Replace the lid if significant damage is observed.
- O-Ring Care: Annually, or more frequently if needed, remove the O-ring, clean it, and apply a silicone-based lubricant designed for pool O-rings. This helps maintain its flexibility and sealing properties. Replace the O-ring if it appears brittle, cracked, or stretched.
- Cleaning: Clean the lid with mild soap and water. Avoid abrasive cleaners or solvents that could damage the plastic.
- Winterization: During winterization, ensure the lid is removed, cleaned, and stored in a dry, protected area if the pump is not in use.
