MAIN CONTROLS
Initial Test
Verify that both of the circuit breakers on the rear panel of the press are
in the ON position (levers pointing to the right). Check that the
Auto/
Manual
switch located on the front panel is in the AUTO position, and
Manual
Manual
that the power switch is in the OFF position. Connect the power cord
to the electrical outlet. Remove any materials from inside the press,
then close and latch the lid. Turn the
Pressure Adjustment Knob
fully
clockwise (maximum vacuum).
Turn on the power switch on the front of the press. The displays on
the
Timer
and
Timer
Timer
Temperature
controllers should light up. The Timer will
normally indicate 2:00 and the temperature controller will indicate
room temperature. Within a minute or so, it will start to increase. After
about 15 minutes, the temperature should reach the setting that was
preset at the factory, normally 194°F (90°C).
Now press the
Start
button on the timer (the one in the upper right
corner). The vacuum pump should start, and the timer should begin to
count down. Within a few seconds, the pointer on the vacuum gauge
should start to move. Within 30 seconds, the reading should be steady
at 25” or higher.
When the timer reaches zero, the pump should automatically cut off,
and the vacuum should automatically be released. Check the vacuum
gauge, which should now be back at a zero reading.
Refer to the Troubleshooting section (pages 15-16) of this manual if
the equipment does not function as described above, or contact Drytac
