8. Hold the corresponding cylinder switch (A CYL or B CYL) in RET (retract) po-
sition until the cylinder fully retracts, and then release the switch.
9. To continue manual operation, repeat Steps 6 - 8.
AUTOMATIC OPERATION – SWITCH / PUSHBUTTON
CONTROLS
1. Turn on electrical power to the control panel.
2. Be sure the EMERGENCY STOP button is pulled out.
3. Depending on the length of liquid supply lines from the carbon dioxide storage
unit, it may be a long time before the machine starts making ice. Use the follow-
ing procedure to get liquid to the machine and reduce the required start-up time.
NOTE: This procedure is not necessary on high capacity pelletizers. To start this
type of machine, simply press the start button. On all other types of pellet izers
manufactured by Tomco
2
, it may be necessary to pre-charge the pelletizer before
starting automatic operation.
To pre-charge the pelletizer, turn the MAN/AUTO switch to the MAN
(manual) position. Place the corresponding injection switch (A INJ or B INJ)
to OFF. Be certain that the compression cylinder is completely retracted and in-
ject liquid CO
2
into the compression cylinder by holding the injection switch
(A INJ or B INJ) in MAN (manual) position until vapor begins to flow through
the extrusion die, and then release the switch. If the pelletizer has two cylin-
ders and both will be used for automatic operation, repeat this process for the
other cylinder.
WARNING
DO NOT INJECT LIQUID CARBON DIOXIDE INTO
THE CYLINDER UNLESS THE CYLINDER IS COM-
PLETELY RETRACTED. DOING SO WILL RESULT
IN CARBON DIOXIDE BEING INJECTED BEHIND
THE PISTON AND WILL RESULT IN DAMAGE TO
THE COMPRESSION CYLINDER, PISTON AND ROD.
