Troubleshooting
Paddle Jams – If the mixing paddle jams for any reason,
switch the power to the mixer off, clear the jam, then turn
the power back on to reset the fault condition, then test
the mixer with an empty mixing bowl/lid to ensure normal
operation. If turning the power off, then on does not reset
the fault, disconnect the power cord from the unit and check
the fuse located in the module where the power cord inserts.
Unit Will Not Turn On – Check the power cord to make
sure the unit is plugged into a working outlet. Make sure
the power switch is in the on position. Check the fuse in
the fuseholder of the power connector. The unit is shipped
with a spare fuse in the fuseholder. Note: Use only a 5
amp fast acting fuse.
Motor Will Not Start – Check for vacuum, by looking at
the vacuum display bars
>>>>. If the bars do not go
all the way across the screen, vacuum is low. If the unit
does not sense enough vacuum the motor will not start.
Make sure all seals are in place and are clean and free of
debris. Make sure the vacuum filter is not clogged. Make
sure the paddle is engaged properly. Try a different paddle
and bowl. If they work, order a replacement for the size that
does not work. If a loud clicking noise is heard when the
paddle is supposed to begin turning call technical support.
Program Restarts – If the vacuum drops in the middle
of a program, the program will play a warning sound and
bowl will drop. The program will stop and go back to the
program selection screen. Check to make sure the correct
program is selected. Reposition the bowl and ensure a
good seal before leaving the bowl.
Display Is Not Working – Check to see if the unit is on.
Reset (cycle the power off then back on) the unit; if the
start-up tune is played but the display is still blank call
technical support.
Start Button Does Not Start the Program – Reset the
unit (cycle the power off then back on) and try again. If the
problem persists the button is probably bad and needs to
be replaced. Call technical support.
Maintenance/Cleaning
Painted Surface – The VPM2 has been painted with
special epoxy based powder coat paint. To clean the
surface, use Windex
®
or water and a clean cloth. Never
use Windex
®
on the display screen as this may cause the
screen to become dry and easy to scratch.
Bowls – Keep bowls clean. Residual materials, set
gypsum or investment, can create contamination issues.
Replace bowls when they show signs of wear. Worn
bowls can reduce reactions of phosphate investments
resulting in casting inconsistency. For a list of solvents
that will harm the bowls call technical support.
O-Ring Maintenance – Lubriplate has been applied to the
O-Rings of the VPM2 to maintain suppleness. If the O-Rings
dry they may not seal properly. Apply Lubriplate monthly to
maintain the O-Rings on both the lids and VPM2.
Vacuum Filter – An extra filter has been supplied with the
VPM2. Replace the filter when the vacuum is clogged or
the filter is soiled. Preventing the vacuum pump becoming
contaminated will extend the life of the VPM2.
To clean filter: Rinse with water and allow to dry before
replacing in VPM2.
