8. Set ram director valve (CC) to down.
Figure 21 Lower the Platen
9. Slowly turn the ram down air regulator (CB)
clockwise to approximately 5–10 psi (34–69 kpa,
0.3–0.7 bar). The platen will begin to lower into
the drum.
10. After the platen seals enter the material drum,
adjust the ram down air regulator (CB) to 30–50
psi (207–345 kPa, 2.1–3.4 bar).
11. When the ram stops, reinsert the platen bleed
stick (R) and hand tighten.
Heat Heat Heat Up Up Up System System System
To reduce the risk of bursting a hose, never
pressurize a hot melt system before turning on the
heat. The air will be locked from the air motor until
all temperature zones are within a preset window
of the temperature setpoints.
Keep the dispense valve open over a waste
container while the system is heating up and also
when cooling down. This will prevent a pressure
build-up caused by fluids or gases expanding from
the heat.
Note
Operate at the lowest temperature and
pressure necessary for your application.
1. Turn the main power switch on the electrical
control panel door to the ON position.
2. Press the button. The zones begin to
heat (provided they are enabled). Press
if the zones do not begin to heat.
Display status bar reads Warm Warm Warm Up Up Up. When

the status will display in the status bar. See
Advanced Display Module (ADM), page 11 , for
operation mode descriptions.
Note
The air will be locked from the air motor
until all temperature zones are within a
preset window of the temperature set
points, allowing the system to heat fully
and complete the material heat soak
period.
