Operator Controls
Become familiar with the operator controls before
operating the bulk melter.
Pneumatic Unit
See Figure 1.
The pneumatic unit controls melt platen movement.
It has a pneumatic switch and two-hand control
buttons.
Pneumatic Switch
Use the pneumatic switch (2) to raise and lower the
melt platen.
Select . . . To . . .
Stop stop melt platen movement.
Lower lower the melt platen.
NOTE: The melt platen can only
be lowered when there is a drum
in the system and the drum clamp
is closed.
Raise
(Aerate Drum) raise the melt platen. If the melt platen is inside of the drum, the
drum is aerated automatically
Refer to Aerating Drum for more
information.
Pressure Controller and Gauge for Operating
Pressure of Cylinders
Operating pressure is applied to the pneumatic
cylinders when the melt platen is lowered into and
raised out of the drum.
Depending on the material to be processed, the
pressure control (4) may need to be set to a different
value. The optimum setting may need to be
determined by trial and error. The gauge (3) displays
the operating pressure.
NOTE: The maximum operating pressure is
7.5 bar (109 psi).
Two-Hand Control
The two-hand control (1) on the pneumatic unit can
only be operated by one person using both hands. It
is used to lower the melt platen into the drum. When
the melt platen enters the drum, the system
automatically switches to the regular lowering mode.
1. Set the pneumatic switch (2) to Lower.
2. Press both buttons on the two-hand control at the
same time (within 0.5 seconds) until the melt
platen enters the drum.

Initial Startup
NOTE: Special test material was used at the factory
to test this system. Residue from this material may be
on the melting plate and in the pump. To remove
residue, melt and feed several kilograms (pounds) of
material before starting production.
1. Ensure that the switch rod is set to the drum
height. Refer to the Adjusting Switch Rod
procedure.
2. Set pneumatic switch to 0/Stop.
3. Set main power switch to I/ON.
4. Set control system.
NOTE: The main power switch must be set to I/ON
when using the week timer.
5. If used, set the week timer. Refer to the Week
Timer manual for procedures.
6. Wait until system is heated and ready for
operation. Green indicator beacon (if present)
and/or indication lamp of control system is lit.
7. Move melt platen to top position.
NOTE: The melt platen sealing rings must be
lubricated before initial startup and every time the
drum is replaced. Remove material residue before
lubricating.
8. Using Centoplex HO, lubricate the melt platen
sealing rings.
9. Insert the drum. Refer to Replacing Drum
procedure.
10. Preselect motor and switch on.
11. Set the motor stroke frequency on the pressure
control to the desired output quantity.
12. If necessary, set the pressure control on the
pneumatic unit to the desired setting. Do not
exceed 7.5 bar (109 psi).
13. Optimize and record the settings.
Daily Startup
NOTE: Do not operate pumps without material.
Before switching on motor, ensure that a drum of
material is in the system and that the melt platen has
contact with the material.
1. Set main switch to I/ON.
2. Wait until system is ready.
3. Check the material drum and replace if
necessary. Refer to Replacing Drum procedure.
4. Lower melt platen into drum.
5. Pre-select motor.
6. Switch on the motor.
Daily Shutdown
NOTE: The melt platen does not need to be moved
out of the drum. 1. Set main switch to 0/OFF and protect with
padlocks if necessary.
2. Set pneumatic switch to 0/Stop.
3. Conduct daily maintenance.
Emergency Shutdown
WARNING: Immediately switch off the
system in any emergency situation. 1. Either set main switch to 0/OFF or press the
optional EMERGENCY OFF button.
2. Set pneumatic switch to 0/Stop.
3. Correct the fault before turning on the system.

Aerating Drum
WARNING: Risk of burns. When the melt
platen leaves the drum, hot material can
come out and/or drip from the melt platen.
Wear suitable protective clothing.
See Figure 4.
If the melt platen is inside of the drum, the drum must
be aerated to support raising. Aerating forces
compressed air under the melt platen.
Drum aeration begins automatically when the
pneumatic switch is set to Raise. Aeration ends when
the pneumatic switch is moved to 0/Stop.

Deaerating Drum
WARNING: Risk of burns. Hot material may
flow out of the deaeration valve. Wear
suitable protective clothing.
See Figure 5.
The drum must always be deaerated when the melt
platen is moved into the drum. When the drum is
deaerated, the air that is under the melt platen
escapes.
See Figure 6.
1. Place a reservoir (3) under the drip pan (2).
2. Verify that the system has reached operating
temperature.
3. Open deaeration valve (1) when the upper
sealing ring on the melt platen (4) is completely
immersed in the drum.
4. Close deaeration valve when the material is free
of bubbles.
5. Properly dispose of material according to local
regulations.

Deaerating System
WARNING: Risk of burns. Hot material may
flow out of the deaeration cock. Wear
suitable protective clothing.
The system must be deaerated upon initial startup
and every time the drum is changed. The system is
equipped with a deaeration cock for this purpose.
NOTE: When the system is deaerated, the drum
must be deaerated at the same time. Refer to
Deaerating Drum for more information.
See Figure 7.
1. Place reservoir (2) under deaeration cock (1). The
deaeration valve is located on the back of the
piston pump.
2. Open deaeration cock.
3. Set motor/pump to medium output quantity, then
switch on.
4. Wait until material flows out free of air.
5. Close deaeration cock.
6. Properly dispose of material according to local
regulations.

Adjusting Switch Rod
See Figure 8.
The system is adapted to the drum height by
adjusting the switch rod. The switch rod activates the
switches (4, 5 and 6) one after the other and thus
triggers the following switching functions.
Switching Functions When Lowering
SSwitch 4 switches from two-hand lowering mode
to normal lowering mode when the upper sealing
ring (3) is completely immersed in the drum.
SSwitch 5 triggers the drum almost empty
indication.
SSwitch 6 triggers the drum empty indication.
Switching Functions When Raising
Switch 4 switches pressurization of pneumatic
cylinders from admission pressure to operating
pressure when the melt platen moves out of the
drum.
Adjust Height
Perform the following:
1. Loosen the nut (1).
2. Adjust the switch rod (2) until it activates switch 4
when the upper sealing ring (3) is completely
immersed in the drum.
3. Tighten the nut.
