Product Overview

The Pentair iChlor Spacer Kit | 523102 is a genuine Pentair replacement accessory designed to temporarily take the place of a compatible salt chlorine generator cell. The spacer maintains a closed plumbing loop so the pool's hydraulic system can continue circulating water while the salt cell is removed for service, cleaning, replacement, or seasonal storage.

Pentair currently specifies 523102 as the spacer cell for IntelliChlor LT15, LT25, and Plus30 salt chlorine generator models.

This spacer is especially useful when removing the chlorine-generating cell during maintenance or winterization without leaving an open section in the pool's return plumbing.

How the Spacer Works

A salt chlorine generator cell is installed directly into the pool's circulation plumbing. When the cell is removed for cleaning, repair, replacement, or storage, the plumbing would normally be left open.

The Pentair 523102 Spacer Cell installs in place of the compatible chlorine generator cell, completing the plumbing connection and allowing water to continue circulating through the pool system.

The spacer itself does not generate chlorine and does not replace the operational function of the salt cell. It is intended strictly as a temporary plumbing bypass or spacer.

Customer-Facing Q&A

Q: What does the Pentair 523102 spacer do?
A: It temporarily replaces the compatible salt chlorine generator cell in the plumbing so the pool circulation system can continue operating while the cell is removed.

Q: Does the spacer generate chlorine?
A: No. The 523102 is a plumbing spacer only and does not contain a chlorine-generating cell or electronics.

Q: Can I use it while cleaning my salt cell?
A: Yes. This is one of the primary uses for the spacer. It allows the pool's plumbing system to remain connected while the chlorine generator cell is removed.

A: Yes. Pentair specifies the 523102 spacer cell for the Plus30, along with the LT15 and LT25.
