Vacuum\pressure system

If the vacuum or pressure appears to be weak or non-existent check the following.
!
The mould baseboard is not restricting the vacuum inlet in the drape table.
!
NOTE: If the mould baseboard is too soft it may pull down under vacuum and block
the vacuum inlet.
!
The mould is adequately vented to allow trapped air to be evacuated.
!
The table and clamp seals are in good order and the table is locking properly at the
top of its travel.
!
There are no holes drilled in the drape table.
If all the above points are OK and you can hear the pump running when you switch it on then
one of the following points will be the cause of the problem. If the pump does not run, refer to
the Electrical trouble shooting section above.
!
A pipe is loose, damaged or blocked.
!
The pump filter is blocked
!
The vacuum\pressure valve is blocked or corroded.
!
The vacuum pump is blocked or corroded.
If the heater has been left in the forward position, with no plastic in the clamp frame, the table
will start to overheat. The pipe attached to the back of the table will shrink and constrict the
passage of air. Pipes become less flexible over time and may loosen or crack.

To check the vacuum filter

Unplug the machine from the mains
Remove the left hand panel. You will see the cylindrical vacuum filter with a pipe attached to
each end. Discard the blocked filter and fit a new one.
