Vacuum Option Cool-Down
(Vac units only)
With this option, the unit includes an internal
venture and bypass line and a modified version of
the automatic cool down function. This works
similarly; however, instead of turning the unit off
after the cool down is complete it will sound the
alarm horn to indicate the unit is ready to be put
into the vacuum mode and the pump remains on. To
initiate a vacuum cool-down, press the Temperature
Adjust button and release and then pressure the On
button. When activated the tank temperature
displays with a C in front of it indicating the
automatic cooling sequence is active. This sequence
will stop at any time if the Stop button is pressed.
