VIKUA Upgraded 320 Pool Chlorinator — Inline Chlorine/Bromine Feeder for Rainbow 320

Effortless inline chlorination for versatile pools

The VIKUA Upgraded 320 Pool Chlorinator is designed as a reliable inline feeder that works with the Pentair Rainbow 320 system. It supports both chlorine and bromine tablets, helping you maintain sanitizer levels with a hands‑off approach. This unit suits residential pools, spa areas, and light commercial settings where steady dosing matters.

Key specifications give a quick sense of scale. The device accommodates 11 large tablets or up to 98 small tablets, enabling you to tailor dosing to pool size and tablet type. In terms of capacity, bottom-feed ranges from about 6,500 to 27,000 gallons, while top-feed covers roughly 18,000 to 70,000 gallons. Air and water interactions vary with installation, water hardness, and tablet strength.

Five thoughtful design features for reliability

• The lid uses a thickened gasket to improve sealing and minimize leaks during cycles.
• A top vent plug safely releases gas to prevent pressure buildup inside the feeder.
• The control valve lets you adjust and close flow with ease for precise dosing.
• A bottom drain simplifies removing residual liquid for cleaner maintenance between cycles.
• The 1/4‑inch feed hose delivers purified water to the chlorination chamber, with the vent plug aiding water ingress for the reaction.

Durability and materials you can trust

Constructed from high‑quality ABS, the unit features a thickened inner wall to resist oxidation and extend service life. A redesigned drainage method offers fast, convenient maintenance that keeps the feeder ready for the next cycle.

Usage and maintenance made straightforward

• All necessary accessories and lubricating oil are included for quick setup.
• Regular lubrication of the chlorinator cover and control valve helps maintain smooth operation.
• Clean the feed hose and interior passages with clean water at regular intervals to slow blockage and corrosion (weekly is recommended).
