7. Confirm that the pump speed is set to the
application requirement. Press the speed control
keys (See Figure 2 (2)) to increase or decrease
pump speed.
WARNING: When the tank lid is open, hot melt
vapors may be released. Vent the application
area or wear a respirator.
8. Check the adhesive level periodically. Refill the
tank before the level drops below 50%.
Manual Shutdown
1. See Figure 1. Press the PUMP control key (10).
The PUMP control indicator (11) turns off and the
pump stops.
2. Place containers beneath all guns and trigger the
guns to relieve hydraulic pressure.
WARNING: Never hang a handgun by its
trigger. The gun can accidentally discharge
material, causing burns.
3. Use one of the following methods to prevent
accidental gun triggering:
Air-operated guns: Reduce air pressure to 0.
Handguns: Lock the trigger safety.
Electric guns: Turn off the gun driver.
4. Press the HEATERS control key (10). The
HEATERS control indicator (11) turns off.
Automatic Startup/Shutdown
The following things happen when the seven-day
clock and auto-energize pump features are on:
The heaters turn on automatically and the pump
can be started when the tank reaches either the
READY condition or a predetermined temperature.
The heaters and pump turn off automatically and
the system shuts itself down.
Maintenance
Daily
1. Clean exterior surfaces of the processor and guns.
2. Check all O-rings and gaskets for leaks.
WARNING: Hot! Risk of burns. Wear
heat-protective clothing, safety goggles, and
heat-protective gloves.
3. Flush the manifold filter using these steps:
a. See Figure 2. Reduce the pump speed to 0 by
pressing the down speed control key (2).
b. Place containers under all guns and trigger the
guns to relieve hydraulic pressure.
c. See Figure 3. Turn off the gas by pressing the
GAS ON/OFF key (1).
d. Open the drain valve (See Figure 4, (7)) over a
container by turning it counterclockwise.
e. Increase the pump speed until a clean, steady
stream of material flows from the drain valve.
f. Close the drain valve by turning it clockwise.
g. Return the pump speed to the normal
operating setting.
Density Reduction Measurement
1. Weigh two empty volumetric containers separately.
(Three-ounce paper cups are acceptable.)
2. Fill one container with solid (non-foamed) hot melt
material. Make sure that the material is level with
the top of the container.
3. Fill the second container with foamed hot melt
material. Make sure that the material is level with
the top of the container.
4. Weigh each of the samples separately and
subtract the container weight from each
measurement.
5. Calculate the density reduction using this formula:
1
Foam Weight
Solid Weight
100 % Density Reduction
6. If the density reduction is not correct, adjust the
density control knob (See Figure 4, (6)) and repeat
the
Density Reduction Measurement
procedure.
