FROG @ease SmartChlor Sanitizing System – Sundance® Spas Low‑Chlorine In‑Line Sanitizer – part #6473‑296

Q: Does this system float in the spa?

A: No—it installs into the in-line cartridge holder built into the filter compartment.

Q: Which Sundance® models is it compatible with?

A: Works with 780, 880, and 980 Series spas (2010+); some older models may require the optional 6473‑315 holder kit.

Q: How much chlorine does it use?

A: It maintains consistent 0.5–1.0 ppm free chlorine using up to 75% less than traditional sanitizers.

Q: How often should I shock or replace cartridges?

A: Shock monthly with the included Jump Start; SmartChlor lasts 3–4 weeks, minerals last 3–4 months.

Q: Do I still need to test water parameters?

A: Yes—weekly testing is required to maintain balanced pH, TA, and hardness using the included @ease strips.

Confirm that your spa model (780/880/980) has the recessed cartridge holder installed—older spas may need part #6473‑315.

Test and balance pH, alkalinity, and hardness using included @ease test strips.

Insert the mineral cartridge and SmartChlor cartridge into the filter holder until fully seated.

Turn spa jets on to activate sanitization; SmartChlor will self‑regulate release over time.

Add the provided Jump Start non‑chlorine shock on first use and with each fill.

Test water weekly; replace SmartChlor cartridge every 3–4 weeks and mineral cartridge every 3–4 months.
