Select Constant vacuum
Selecting constant vacuum will cause the vacuum pump
to run continuously during the vacuum cycle of a program.
1. Press the
Special Functions
button.
2. Turn the
Select Knob
until the display reads
CONSTANT VC PUMP.
3. Press the
Next
button.
4. Turn the
Select Knob
to display YES or NO. A
selection of YES will cause the vacuum pump to run
continuously during the vacuum cycle of a program.
A selection of NO will allow the vacuum pump to
turn off and on to maintain the set vacuum level.
If intermittant vacuum is selected but the vacuum
pump runs continuously during the program cycle,
the vacuum level is set too high. The actual level is
within 3% of the selected level, but the pump can-
not reach the full selected level. This can be cor-
rected by reducing the vacuum level. See page 11
for more detail.
