Operation
Daily Start-up Procedure
PRESSURIZED FLUID HAZARD
To reduce the risk of serious bodily inju-
ry, such as fluid injection or splashing
fluid in the eyes or on the skin, ALWAYS
wear eye protection and protective clothing when
installing, operating, or servicing this dispensing
system.
WARNING
There are 2 ways to start up the system. You can
either:
D manually start the system each day
D use the optional 7-day timer to heat up the system
unattended
If you manually start up the system, be sure to allow at
least 30 minutes for the material to fully heat up before
the system is ready for use.
If you use the optional 7-day timer to heat up the
system, you must:
D
create a schedule and program it into the 7-day
timer (see the documentation that came with the
electrical control panel). Be sure to allow at least 30
minutes for the material to heat up before the
supply unit is ready for use.
D perform specific procedures each night to make the
system ready for automatic operation.
Starting the System Manually
To start the system manually:
1. Verify that the main disconnect is ON.
2. Turn the CONTROL ON switch to ON.
3. Open the dispense valve over a waste container to
allow the material to expand. This will prevent
damage to the equipment.
4. After each of the dispense zones is heated to op-
erating temperature, wait an additional 30 minutes
to allow the material to heat fully.
5. Make sure that all material valves are open.
6. Turn the pump air supply ON and set the regulator
for normal operation.
7. Dispense some material into a waste container.
8. Verify the flow rate is correct; adjust if required.
With the material heated, and the flow rate corrected
as necessary, the system is ready for operation.
WARNING
Do not over pressurize the system, as this could
result in serious injury or damage to the equipment.
NOTE:
It is normal for the pump to stop moving if the
dispense gun or other fluid valve is closed.
Using the 7-Day Timer
The optional 7-Day Timer allows you to automatically
heat the system without having to manually turn on the
heat.
Before you can use this feature, you must program the
7-day timer, located on the electrical control panel. For
more information about programming the timer, see
the documentation that came with the electronic con-
trol panel.
Each Night:
Follow this procedure each time you use the 7-day
timer:
1. Turn the CONTROL ON (61) switch to AUTO.
2. Turn the HEAT switch (62) on the electrical control
panel to ON.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure (page 21).
3. Relieve the supply unit pressure.
4. Leave the dispense valve open and over an empty
waste container, to relieve pressure that could
build up while the system is heating.
5. Make sure that all material valves are open.
6. Make sure the pump air supply has been turned
OFF.
The system is ready for start-up with the 7-day timer.
