Operation
Heating Up the Gun and System
WARNING
PRESSURE RUPTURE HAZARD
Heating fluid expands, causing a rise in
pressure in a closed system.
D Be sure pressure is relieved before
heating up the equipment. Follow the
pressure Relieving Pressure Proce-
dure on page 7.
D Engage trigger retainer to hold
dispense gun open to prevent exces-
sive pressure build-up from fluid
expansion
1. Be sure pump is off.
2. Engage the dispense gun trigger retainer to hold
the valve open.
3. Activate the heat controls.
4. After pump, hose, and gun are up to temperature,
disengage gun trigger retainer to close the valve.
Engage the gun trigger safety to prevent acciden-
tal dispense of high pressure heated fluid.
Dispensing
1. Start the fluid supply pump.
2. The fluid flow rate is controlled at the pump. Adjust
the pump pressure to obtain the desired flow rate.
It is recommended that you use the lowest pres-
sure necessary to dispense the fluid. The pressure
adjustment will depend on the hose length, the
viscosity of the fluid, and the gun nozzle size.
3. Unlock the gun trigger safety.
4. Squeeze the trigger in all the way. Fluid flow
begins with the slightest pressure on the trigger
and stops when the trigger is released.
Flushing Safety
WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of a fire, explosion, or
serious injury,
D Be sure the entire system and flush-
ing pails are properly grounded
before flushing the gun or system.
Read Grounding the System, on page 6.
D Use the lowest possible fluid pressure and
maintain firm metal-to-metal contact between
the gun and the grounded metal pail during
flushing.
D Heat controls must be off during flushing if
solvents are used to flush.
Shutting Down
1. Turn off all heat at the controller.
2. Turn off fluid pump.
3. Trigger gun to relieve pressure while system is still
hot.
4. With gun over a waste container, engage gun
trigger retainer to hold valve open for next heat-up
cycle.
