Setting Heater Control
(Refer to FIG. 11)
1. Set the heater control knob (33) to a trial setpoint of
4 or 5.
2. Start the pump and circulate fluid through the sys-
tem at very low pressure, about 10-12 oz/min
(0.30-0.35 liter/min).
3. After 10 minutes, read the temperature on the ther-
mometer (2). If it does not match the desired tem-
perature, adjust the setpoint.
Adjusting for Spraying
1. Adjust pump pressure and heater setpoint to the
lowest settings needed for good fluid atomization.
2. Set all system back pressure valves (S - F
IG. 1) to
maintain even fluid pressure at all gun stations.

CAUTION
Operating the heater at its highest setting, over 180°F
(82°C), for long periods of time decreases the heater
life and can cause fluid to dry out; which can clog the
heater and result in a poor finish.
