| Power supply voltage | 220V~ 50Hz |
|---|---|
| Minimum circuit breaker rating | 20 A |
| Water inlet pressure range | 0.15–0.5 MPa |
| Required pipe diameter | DN15 PPR |
| Maximum pipe length without extra refrigerant | 3 m |
Open the drain valve, close the inlet valve, and turn the drain plug until no water flows out, then the tank is fully drained.
Ensure a reliable ground, install a residual‑current protective device, and use a dedicated circuit with a breaker rated at least 20 A.
Use DN15 PPR pipe with G1/2 threaded fittings and provide proper insulation for the pipe.
The inlet pressure must be between 0.15 MPa and 0.5 MPa; add a pressure‑reducing valve if higher, or a booster pump if lower.
