Why does my Graco Industrial Equipment hose not maintain temperature while spraying?
- M
  Michael CainSep 9, 2025
  If the hose temperature isn't maintained during spraying, consider: * Setpoint adjustment: Increase A and B setpoints, as the hose is designed to maintain, not increase, temperature. * Ambient temperature: If it's too cold, increase A and B setpoints. * Flow rate: Use a smaller mix chamber or decrease pressure if the flow is too high. * Preheating: Ensure the hose is fully preheated before spraying. * Voltage: Verify the line voltage, as low voltage reduces power to the hose heat system.

What causes erratic display on Graco Industrial Equipment; display turns on and off?
- J
  John PowellAug 27, 2025
  An erratic display that turns on and off may be due to: * Low voltage: Ensure the input voltage is within specifications. * Poor display connection: Check cable connections and replace any damaged cables. * Damaged display cable: Clean corroded connections or replace the cable if damaged. * Ungrounded display cable: Ground the cable. * Excessively long display extension cable: Ensure the cable does not exceed 100 ft (30.5 m).

Why is my Graco Industrial Equipment hose temperature exceeding the set point?
- H
  hallmichaelAug 27, 2025
  If the hose temperature exceeds the set point, consider these causes: * Overheating heaters: Check primary heaters for thermocouple problems or a failed element. * Faulty thermocouple connections: Ensure FTS connections are snug and clean. Also, check the connections of thermocouples to the long green plug on the heater control board, cleaning off any debris and re-plugging the wires and connector. * Damaged insulation: Ensure the hose bundle has adequate insulation evenly covering the entire length and connection joints.

  joseph16Aug 30, 2025
  Erratic hose temperature can result from: * Faulty thermocouple connections: Ensure all FTS connections are snug and clean. Check connections of thermocouples to the long green plug on the heater control board, cleaning any debris and re-plugging the wires and connector. * Incorrect FTS installation: Verify the FTS is installed close to the end of the hose, in the same environment as the gun. * Damaged insulation: Ensure the hose bundle has adequate insulation evenly covering the entire length and connection joints.

What causes low pump output in Graco Industrial Equipment?
- D
  David WardSep 5, 2025
  Low pump output can be attributed to: * Obstructions: Clear any obstructions in the fluid hose or gun, and use a hose with a larger ID. * Pump valves: Consult the pump manual regarding worn piston or intake valves in the displacement pump. * Pressure setpoint: Reduce the pressure setpoint to increase output.
