Heatup Guidelines
The fluids must be circulated from the pumps through
the heater, hoses, and back to the tanks to ensure warm
fluids are supplied to the gun.
Slow Recirculation
• Slow Recirc results in a higher temperature transfer
in the heater, so hoses and gun heat up quicker.
• Good for touchup or low flow spraying, up to moder-
ate temperature.
Fast Recirculation
Fast Recirc keeps heaters on full-time to bring fluid
tanks up to temperature. The higher your flow rate, the
more heat needed in the tanks before spraying.
•
For 230 V systems: Use Fast Recirc until pump inlet
fluid temperature gauges (Y) are within 45°F (25°C)
of target outlet temperature.
•
For 120 V systems: Use Fast Recirc until pump inlet
fluid temperature gauges (Y) are within 30°F (17°C)
of target temperature.
•
Volume in tanks: Use only what you need. For
example, 2.5 gal. (10 l) in each tank will heat up
almost twice as fast as 5 gal. (20 l).
• Mixes fluid within tanks, to avoid heating only the
fluid at the top of the tank.
• Use for flushing.
Heat Management Tips
• Heaters perform better with lower flow rates or
smaller mix modules.
• Triggering the gun for short periods helps maintain
efficient heat transfer, keeping material at the
desired temperature. Triggering the gun for a long
period may not allow enough heating time, depend-
ing on material temperature in tanks.
• If temperature displays fall below acceptable limits,
set function knob to Slow Recirculation and cir-
culate again to bring temperatures back up.
• Each 35 ft (10.7 m) hose bundle adds about 5 min-
utes to heatup time, with most materials. Maximum
recommended hose length is 105 ft (32 m).
• For a quicker start, do initial heatup circulation with
the tanks 1/4 to 1/3 filled, then add more material.
