3. Step-by-step maintenance guide
Step 1: Basic investigation
① Check whether the heating main valve is fully open (open when the handle is parallel to the pipe)
② Observe the pressure gauge (1.5-2Bar is normal)
③ Touch the temperature difference of the pipes (the inlet pipe should be obviously hotter than the return pipe)
Step 2: Exhaust Treatment
① Use a flat screwdriver to turn the exhaust valve counterclockwise
② Until continuous water flow is discharged (about 30-60 seconds)
③ Pay attention to using a container to collect water to prevent the floor from soaking
Step 3: Clean the filter
① Close the water inlet valve (important!)
② Use an adjustable wrench to remove the Y-type filter
③ Clean the filter with a wire brush and reinstall it as it is.
