Applications & Compatibility Notes
This Drive Kit is intended for use in select Pentair variable-speed pool pump models where the original drive has failed or obsolete. Before installing, verify your pump model number, manufacture date and ensure your motor and housing are compatible. Using the correct drive kit ensures reliable system operation and avoids mis-match issues.
Installation Instructions
- Turn off electrical power to the pump and lock out the circuit before beginning work.
- Remove the existing drive assembly and keypad from the pump housing, disconnect all wiring carefully and note original orientation.
- Install the new 356879Z kit components—drive, keypad, cover and hardware—following manufacturer torque and wiring guidelines.
- Restore power and prime the pump; configure settings via keypad as needed and monitor for proper operation and absence of error codes.
Troubleshooting
-
Pump not powering up: Verify correct voltage, breaker and wiring harness connection to the new drive.
-
Error codes on keypad: Check wiring harness pin alignment, verify compatible pump model and ensure firmware in drive matches your motor housing.
-
Reduced performance or unusual noise: Confirm pump impeller clearance and alignment—drive replacement may reveal underlying wet-end wear.
Maintenance Tip
Inspect your variable-speed drive during annual pump service. If the keypad display dims, error codes recur, or the drive overheats, replacing with the 356879Z kit can restore full functionality and extend the life of your pump system.
