Erratic Hose Temperature
To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.
Verify that all FTS connections are snug and that the connector pins are clean. See Wiring Schematics in product manual. Examine connection of FTS to temperature control (AG) terminals. Unplug and re-plug FTS wires, cleaning off any debris. Unscrew wire terminals (TCM 1-9, TCM 1-10) on temperature control, clean the FTS wires, and re-tighten terminal screws.
FTS should be installed close to the end of the hose in the same environment as the gun. Verify correct FTS installation, see product manual.
Ensure hose bundle has adequate insulation evenly covering the entire length and connection joints.
