- Page 12 800 826 5537 03/24/2017 Trouble shooting for electricians CE and CES Series troubleshooting. Be sure you are a qualified electrician before proceeding. This series of units operates off a flow meter and computer board that turn the units elements on and off. The thermostats in this unit are solely a safety feature to shut the unit down in case of failure.
- Page 13 800 826 5537 03/24/2017 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.

- Page 15 800 826 5537 03/24/2017 If the unit is still not working do the following tests before proceeding. Turn off the main power. Determine if the elements ohm to their correct reading… : Ohms Test: Check each element(#4 in the above picture) with an OHMs meter for correct readings. If the elements reads 0 or flickers it is bad and needs to be replaced.
- Page 16 800 826 5537 03/24/2017 TRIAC REPLACEMENT PROCEDURES 1. You need an allen wrench to loosen the screws that hold the trica to the plate. 2. Remove the three wires. 3. Put the white heat sync paste that came with the tric on the back of the triac. 4.
- Page 17 800 826 5537 03/24/2017 Check the line voltage and be sure you are receiving the proper voltage across two of the three lines of your three phase heater.
