Enough Water Flow(Check your Pump)

for this heater the important thing need to make sure enough water flow,suggest the pump not less than 200 wat (3600 L/ h), enough flow to turn on

flow switch "TRIPS" and when the flow decreases to NOT enough it shuts the heater down. That way if for some reason the flow is too slow it will not over heat the unit and it will not even work at all till the flows correct.

Correct Installation Direction

Make sure the mount direction is correct, there is a arrow direction shows the water inlet and outlet marked on the heater, pls ensure that the water flow is in the same direction as the arrow direction on the heater,wrong direction will not make the heater work.

Adjustable Temperature

Adjustable temperature range is 0-45 ℃ （32ºF~113ºF）,when the water temperature reaches the set temperature,it will stop automatically. when temperature is dropped down, it will heat up water until your set temperature.If temperature exceed 60℃(139ºF), reset button will flick out and cut off the power.

1.5" Standard Pipe

Standard pipe size 1.5 inch， smaller pipe can not make sure enough flow volume.
