parts have failed. The fuse is in the fuse enclosure between the triac and the element and is denoted on the
picture on page 11, item #16.

If the unit is still not heating the fluid as well as you think it should then do the following test.
Turn the flow on and the heat up till the board flashes at you like it says ther e is a full load on the unit.
Using an AMP gauge test each of the three phases for Amperage. On the from panel of the unit the name plate shows
the full load AMP draw for the unit. Compare that to the test you just did. If they are the same then the unit is doing
all it can do and you need to slow the flow or lower the heat level.

If it is not pulling a full load document the draw on each line and compare it to the full load draw.
The lines the have a lower Amp draw have a part that is not working and it is probably an element or a thermostat in
that circuit.
Too much heat
1.
This generally occurs when a triac fails and does not properly shut off the electricity flow to the elements. In this
case the thermostats sut the unit down but the customer will not be able to adjust the output temperature.
Find the failed triac by shutting off the flow and do the AMP draw test above. At no flow there should be no AMP
draw or minimal to light up the pilot lights.
2.
Find the triac that is the problem by finding the element that is receiving AMP draw with an AMP gauge or by
testing the triac with the power off for an ohms reading. They should all be in around .63 ohms when measured
across the gate to the line.
You will have continuity always across the power lines of the triac if the triac has failed. Please also refer to the
tests following the drawing of the inside of the unit.

The following picture shows the inside of an electronic heater as a reference to the parts discussed.
