Focus on four core areas: power supply, wiring, water flow, and installation.
1. Power & Voltage Matching
- Do NOT mismatch voltage, which causes weak heating or burnout.
- High-power units need 220–240V and a dedicated circuit; do NOT use regular outlets or shared circuits.
- Check the rating label and panel capacity before installation.
2. Wiring & Circuit Breaker
- For 8–27 kW units, use properly sized wiring and breakers to prevent overheating and fire.
- Use permanent wiring only; extension cords and temporary cables are prohibited.
- One dedicated grounded circuit per heater.
3. Terminal Wiring
- For dual‑voltage models, follow the wiring diagram exactly; do NOT rewire voltage manually.
- Tighten all terminals, use proper connectors for mixed wiring, and securely ground the unit.
4. Water Flow & Activation
- The heater requires minimum flow to turn on.
- If it does not heat or flashes, check the pump, aerator, and valves.
- Flush air from the lines before turning on power.
5. Location & Plumbing
- Install close to the point of use to reduce heat loss.
- Mount in a dry, frost‑free, accessible area.
- Install service valves, test for leaks, before applying power.
Installation Checklist
- Voltage and power match the electrical panel
- Correct wiring and breaker size, dedicated grounded circuit
- Follow wiring diagram for dual‑voltage models
- Flush lines and ensure sufficient flow
- Test for leaks before powering on
