Low water pressure start-up function: When water supply pressure is lower than 0.025Mpa, the water heater cannot be ignited. Fit water pressure pump to boost pressure.

Anti-freeze protection: When temperature is very low, remove the water discharge valve to discharge accumulated water inside the water pipe to avoid damage caused by freezing when the water heater is not in use.

High-pressure protection: Once water pressure is over 0.8Mpa, the water discharge valve will release water & lower the pressure. This will happen automatically to avoid damage.”
