Q: What should I verify before buying?
A: Confirm your existing system is IN.YE5 V3, matches 4kW heater configuration, and supports the same voltage and pump setup to ensure correct replacement.

• Keep the equipment bay dry, ventilated, and protected from condensation to prevent corrosion of the Gecko IN.YE5 V3 control electronics and heater terminals.
• Maintain clean filters and strong water flow—restricted flow can trigger heater protection shutdowns and stress the control pack over time.
• Never run the system without proper water level or circulation; ensure pumps are fully primed after refilling or service to avoid dry-fire errors.
• Inspect heater, pump, and sensor connections periodically for tightness, corrosion, or heat discoloration to prevent intermittent faults.
• Protect the pack with stable 230V supply and proper GFCI protection to reduce risk of damage from voltage spikes.
• Keep water chemistry balanced (pH, alkalinity, calcium hardness) to reduce scale buildup on the 4kW heater and extend component life.
• After any replacement or service, verify configuration settings (voltage, pump setup, sensors) match the spa requirements before powering on.
