Operation
Raising and Lowering the Ram
The ram hand valve on the ram air control has 3
positions (Fig. 23):
CAUTION
An empty drum clamp can interfere with up and
down operation of the ram. When raising or lowering
the ram, make sure the drum clamp stays clear of
the follower assembly.
Ram UP raises the ram
Ram DOWN lowers the ram
Ram OFF puts the ram in “neutral.” Moving the
hand valve to OFF does not change the position of
the ram, but it stops the air pressure from attempt-
ing to move the ram either up or down.

Daily Start-up Procedure
WARNING
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 cloth-
ing when installing, operating, or servic-
ing this dispensing system.
There are 2 ways to start up the hot-melt system. You
can either:
manually start the system each day
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 45 minutes for the material to fully heat up before
the system is ready for use.
NOTE:
The auto depressurization circuit automatically
delays operation of the pump for 45 minutes.
If you use the optional 7-day timer to heat up the
system, you must:
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
45 minutes for the material to heat up before the
supply unit is ready for use.
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 45 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.
