Section 15 Servicing–Heat Exchanger Module
Replacing the Heat Exchanger Module
1. Drain the water and dye solvent from the tank.
2. Unplug P2 from the AC distribution PCB.
3. Disconnect the water tubing from the manifold as it exits to the top of the heat exchanger.
Blow into the tubing segment that is still attached to purge the fluid from the heat
exchanger. Loosen the dye tubing at the compression fitting on the head exiting to the
heat exchanger. The solvent will drain once a vent is created. Use another piece of clean
tubing to blow out any remaining solvent from the heat exchanger.
4. Remove the tubing attached to the heat exchanger, top and bottom.
5. Remove the 4 nuts that hold the heat exchanger to the frame.
6. Slide the heat exchanger off the mounts, and then remove from the laser
7. Reassemble by reversing the previous steps.
Replacing the Temperature Sensor(s)
There are two temperature sensors on the Cynergy laser, one for temperature of the dye solvent
and one for temperature of the water. They are the same assembly and one must be careful to
attach them to the proper spot on the AC Distribution PCB.
1.
Drain the water (or dye solvent) from the tank. If dye solvent is drained, disconnect the
dye filter from the connections behind the front door and set aside.
2. Unplug P13 (or P12) from the AC distribution PCB.
3. Unscrew the temperature sensor from the heat exchanger.
4. Wrap the threads of the new temperature sensor with Teflon tape.
5. Install the new temperature sensor into the heat exchanger.
6. Plug P13 (or P12) back into the AC distribution PCB.
7. Fill the tank with water (or dye solvent). Reconnect the dye filter. Check for leaks.
