Before performing any troubleshooting procedures:
1. Follow
2. Turn the main power switch OFF.
3. Allow equipment to cool.
Cause
Cause Cause
Ambient temperature is too cold.
FTS failed or not installed correctly. Check FTS, see
Low supply voltage.
If Hose Resistance Mode is
enabled, the calibration factor may
be inaccurate.
A and B setpoints too low.
Ambient temperature is too cold.
Flow too high.
Hose was not fully preheated.
Low supply voltage.
If Hose Resistance Mode is
enabled, the calibration factor may
be inaccurate.

Solution
Solution Solution
Relocate hoses to a warmer area
or recirculate heated fluid through
the hose.
Cables and FTS, page
Verify line voltage. Low line
voltage significantly reduces
power available to the hose heat
system, affecting longer hose
lengths.
Re-calibrate the hose. Follow the
Calibration Procedure, page
Increase A and B setpoints.
Hose is designed to maintain
temperature, not to increase it.
Increase A and B setpoints to
increase fluid temperature and
keep it steady.
Use smaller mix chamber.
Decrease pressure.
Wait for hose to heat to correct
temperature before spraying.
Verify line voltage. Low line
voltage significantly reduces
power available to the hose heat
system, affecting longer hose
lengths.
Re-calibrate the hose. Follow the
