Product Overview

The Caretaker Motor Mount Assembly Start-Up Kit | 4-7-310 is a replacement start-up kit designed for compatible Caretaker Ultraflex2 in-floor pool cleaning systems.

This kit includes the key electronic and mechanical components needed to help restore proper valve operation, including the motor, sensor, and sensor PCB board. It is used on compatible Caretaker UltraFlex 2 8-port electronic in-floor cleaner valves and is intended to help restore proper indexing, zone control, and water distribution through the in-floor cleaning system.

When the existing motor assembly, sensor, or sensor board fails, the valve may stop rotating correctly, fail to index zones, or send water unevenly through the pool cleaning circuits. Replacing the start-up kit can help restore reliable system operation without replacing the full valve assembly.

Ideal For

• Caretaker Ultraflex2 in-floor cleaning systems
• UltraFlex 2 8-port electronic valve systems
• Replacing failed motor mount assemblies
• Replacing damaged sensor assemblies
• Replacing faulty sensor PCB boards
• Restoring valve indexing and zone control
• Repairing in-floor systems stuck on one zone
• Improving water distribution to cleaning heads
• Pool service professionals repairing electronic valve systems
• In-floor cleaning system start-up and refurbishment

Key Features

• Complete start-up kit — includes motor, sensor, and sensor PCB board for compatible Ultraflex2 systems.
• Designed for Caretaker UltraFlex2 — made for compatible Caretaker electronic in-floor cleaning valve systems.
• Used on 8-port electronic cleaner valves — supports proper valve operation and zone sequencing.
• Motor assembly included — restores mechanical valve movement when the original motor has failed.
• Sensor assembly included — helps the system identify valve position and indexing status.
• Sensor PCB board included — supports communication between the sensor and control system.
• Helps restore zone cycling — assists with proper distribution of water through cleaning zones.
• Factory original replacement part — commonly listed as a Polaris / Zodiac / Caretaker replacement component.
• Service-friendly kit — replaces multiple related components together for a more complete repair.
• Professional-grade repair solution — ideal for technicians servicing advanced in-floor cleaning systems.

Benefits

The Caretaker 4-7-310 Start-Up Kit helps bring compatible Ultraflex2 in-floor cleaning systems back to proper operation. If the motor, sensor, or sensor PCB board fails, the system may stop indexing correctly, causing weak cleaning performance, poor circulation, or one zone receiving flow while others do not.

Replacing these components as a kit helps restore communication and movement within the electronic valve assembly. This can improve pop-up head performance, zone sequencing, and overall in-floor cleaning system reliability.

For pool professionals, this kit helps avoid sourcing individual components separately and provides the main motor and sensor components needed for compatible Ultraflex2 valve repairs.

Specifications

Included Components

• 1 × motor assembly

Valve body, valve lid, gear components, plumbing base, cleaning heads, control box, wiring harnesses, water valve shell, O-rings, and installation labor are sold separately unless specifically included by the supplier.

Compatibility Notes

This kit is designed for compatible Caretaker Ultraflex2 / UltraFlex 2 8-port electronic in-floor cleaner valve systems.

Common compatibility references include:

• Caretaker Ultraflex2 in-floor cleaning systems
• UltraFlex 2 electronic valve systems
• Caretaker UltraFlex 2 8-port electronic in-floor cleaner valves
• Zodiac / Polaris / Caretaker 4-7-310 replacement applications

Always verify the existing valve model, part diagram, electronic control setup, and motor/sensor configuration before ordering. This kit is not intended for standard mechanical water valves or non-Ultraflex2 systems.

Installation Notes

This start-up kit should be installed by a qualified pool professional familiar with Caretaker electronic in-floor cleaning systems. Turn off all power to the control system and pool equipment before servicing the valve assembly.

Inspect the existing motor mount area, sensor connection, PCB board, wiring, valve internals, O-rings, control wiring, and water valve condition before installation. After installation, verify that the system indexes through the zones correctly and that the cleaning heads receive proper water flow.

If the valve still does not operate correctly after replacement, check power supply, control board, wiring connections, valve obstructions, system flow, filter pressure, and zone plumbing.
