Before cleaning, manually turn off the power supply, close the water inlet valve, open the water outlet valve, open the drain valve of the safety valve, and rotate 90 degrees counterclockwise to discharge the water and sediment in the water tank of the air energy water heater.
The water storage tank stores an appropriate amount of water and keeps it circulating. The outlet valve is closed and the drain valve is closed.
Add the scale remover of air energy water heater into the water storage bucket according to the ratio of 1: 10-50, and soak it in self-circulating/special equipment for 30-45 minutes.
After descaling is completed, open the drain valve to discharge the cleaning waste liquid. Close the drain valve, turn on the water supply switch, inject a proper amount of clean water, circulate and clean for half an hour before discharging, and repeat the above process for 2-3 times to complete the cleaning of the inner barrel.
