Precaution on pipe searching process
1. Please choose the ‘Mode’ according to the water temperature
- Use ‘Mode 1’ if water temperature is higher than 30 ℃(86 ℉)
- Use ‘Mode 2’ if water temperature is lower than 30 ℃(86 ℉)
2. Be sure that water pump is operating during the pipe searching process
- If the water circulation is not detected by water flow switch, ‘CH14’ error will occur.
