Pentair Chlorine Container for IntelliChem Chemical Controller, 4 Gal, 521397

The Pentair Chlorine Container for IntelliChem Chemical Controller, 4 Gal, 521397, is the chlorine container for the IntelliChem water chemistry controller. Pentair sells it without a pump, so it needs a separate pump.

What it is

Pentair lists 521397 as a 4 gallon chlorine container, and its installation sheet describes a 3-1/2 gallon capacity container for chlorine, for use with IntelliChem and other pool water chemistry controllers. An internal piercing mechanism punctures the seal of the liquid chlorine bottle so the container fills without spills. The lid is smoke colored, the top half is black, the bottom half is clear so the level can be seen, and the base is black. The base has four mounting holes for 1/4 in. bolts into the equipment pad.

Chlorine, not acid

The acid side uses its own container, 521378. Pentair also sells the chlorine tank with a tank mounted pump as 522473, so choose 521397 only when you already have, or are supplying, the pump.

Before you order

Pentair lists the chlorine container lid (521506), the lid O-rings (521507), the suction fitting (521508) and the vent fitting (521509) as separate parts. Pentair warns that mixing chemicals with chlorine or chlorine residue in the container can create a deadly gas or an explosion, so never use it for anything but chlorine.
