Product Overview

The Pentair IntelliFlo and IntelliPro VSF Drive Kit with Keypad 356922Z is a genuine replacement electronic drive assembly designed for compatible Pentair IntelliFlo VSF and Pentair IntelliPro VSF variable-speed and variable-flow pool pumps.

The drive controls the pump motor and manages speed, flow, scheduling, priming, diagnostics, and automation communication. This kit includes the operator keypad, allowing it to replace a damaged or failed drive and control interface as a complete assembly.

The 356922Z is intended for professional pump repair. Because Pentair has produced multiple generations of IntelliFlo and IntelliPro pumps with different drive configurations, compatibility must be confirmed using the complete pump model, serial number, production date, and original drive part number.

Compatible Pump Families

The 356922Z drive kit is intended for select pumps within the following Pentair product families:

• Pentair IntelliFlo VSF
• Pentair IntelliPro VSF

This part should not be assumed to fit every IntelliFlo or IntelliPro pump. Pumps carrying similar product names may use different motors, drives, keypads, wiring connections, or firmware.

Not Universally Compatible

Do not assume this drive fits:

• Every IntelliFlo pump
• Every IntelliPro pump
• IntelliFlo3 pumps
• IntelliFlo VS+SVRS pumps
• IntelliFloXF pumps
• IntelliFlo i1 pumps
• Standard variable-speed-only models
• Pumps with a different drive or motor generation

Always match the replacement part to the complete pump identification label.

Common Reasons for Replacement

The complete drive kit may be required when the pump experiences:

• Blank or nonresponsive keypad
• Failed electronic drive
• Repeated drive fault messages
• Pump will not start despite proper incoming power
• Speed or flow settings cannot be programmed
• Intermittent motor operation
• Automation communication failure
• Visible corrosion or moisture damage
• Burned internal electronics
• Electrical surge damage
• Physical damage to the keypad or drive housing

A blank keypad does not automatically mean the complete drive has failed. The incoming voltage, keypad connection, wiring, motor, and communication components should be professionally tested before replacement.

Confirm Before Ordering

• Verify the complete pump model number.
• Record the pump serial number.
• Confirm the pump’s production date.
• Verify that the pump is a VSF model.
• Compare the original drive part number with 356922Z.
• Inspect the wiring and connector configuration.
• Confirm motor compatibility.
• Test incoming voltage before replacing the drive.
• Inspect the pump for moisture intrusion or corrosion.
• Do not order based only on the IntelliFlo or IntelliPro name.
• Professional diagnosis is recommended before purchasing.

Installation Information

Turn off and lock out all electrical power before servicing the pump. Variable-speed pump drives contain high-voltage electronic components and should only be serviced by qualified personnel.

Before installing the replacement drive, inspect:

• Incoming voltage
• Grounding and bonding
• Motor condition
• Motor-to-drive connections
• Communication wiring
• Keypad connections
• Drive housing seals
• Evidence of moisture intrusion
• Pump shaft movement
• Existing fault codes

After installation, the pump may need to be reprogrammed for:

• Speeds
• Flow rates
• Schedules
• Priming
• Freeze protection
• Automation communication
• Pool and spa operating functions

No. This listing is for the drive kit with keypad only. The motor, wet end, plumbing unions, and complete pump are not included.

Does this fit both IntelliFlo and IntelliPro pumps?
It is intended for select IntelliFlo and IntelliPro VSF models. Compatibility must be confirmed using the complete pump model and serial number.

Does this drive support both speed and flow programming?
Yes, when installed on a compatible VSF pump, the drive supports variable-speed and variable-flow operation.

Will this repair a blank pump display?
It may, but a blank display may also be caused by incorrect voltage, wiring damage, a loose connector, motor failure, or moisture intrusion. Professional diagnosis is recommended.

Does the replacement drive require programming?
Yes. Speeds, flow settings, schedules, priming, and automation communication may need to be reconfigured after installation.

Is professional installation required?
Yes. The drive contains high-voltage electronic components and should be installed by a qualified pool-equipment technician or electrician.
