VacuFormer
Introduction
Dear new user,
Thank you for purchasing the Cavex VacuFormer (CVF) and
congratulations on your choice.
Although the CVF is fairly easy to use, we strongly recommend
you to read this manual carefully before you start!
To become familiar with using the different deep-draw variants
(splint, whitening tray, dental protector, bite splint), we advise
you to practise making a number of moulds based on the
protocols described in this manual.
NOTE!
Do not place the Cavex VacuFormer too close to walls,
cupboards, other equipment, etc. Place the CVF on a stable
surface with sufficient space around it.

VacuFormer
Instructions for use
1. Swivel the heating element to the rear and
press the Heating switch (fig. 1).
Preheating takes around 3 minutes.
Preheating is not always necessary but is
always recommended for sheets thinner
than 1 mm.
2. Place the required deep-draw sheet in the
frame (fig. 2) and close it carefully.
Slide the frame all the way up (fig. 3).

Instructions for use
3. Place the impression on the vacuum
plate (fig. 4)
TiP:
Ensure that the base of the
impression is not too high. If it is, the
sheet will be drawn occlusively too thin,
which increases the likelihood of cracks
in the incisal edges.
4. Swivel the heating element over the
frame with the deep-draw sheet (fig. 5).
Preheat the sheet until it hangs down by
2 to 3 centimetres (fig. 6)

Instructions for use
5. Swivel the heating element to the rear
again. Switch on the vacuum motor and
use the handles (fig. 7) to pull the
frame down over the impression.
Allow the motor to run until the sheet
has cooled.
6. Remove the impression from the
deep-draw sheet (fig. 8) and cut away
the flat part of the sheet.
7. Snip or cut the sheet as indicated to
achieve the required result.
NOTE!
!!
Only use earthed power outlets.
!!
For indoor use only.
!!
The CVF has overheating protection. The mechanism is automatically
activated when the CVF is used for too long.
!!
Let the Cavex VacuFormer cool for at least 10 minutes after use.
This prevents overheating.
!!
Do not leave the heating element over the handles for too long.
The intense heat could melt them. The handles could also become
hot enough to burn your hands.

Frequently asked questions / problems
i.
The deep-draw sheet tears and/or stretches too much:
This can happen when the sheet has become too hot. The problem
can be prevented by preheating sufficiently and swivelling the heating
element to the rear in good time.
i.
The sheet becomes extremely thin at the incisal edges:
This is often caused by a cast being too high. Trim the cast to a height
of no more than 2.5 centimetres. This problem can be caused by the
cast being too centralised. Place the anterior part closer to the centre.
i.
Insufficient detail:
This is often caused by insufficient heating or a vacuum period that
is too short.
i.
The sheet gets stuck in the vacuum holes:
Overheating makes the sheet so soft that it is sucked into the
vacuum holes during the vacuum process. Prevent overheating.
Carefully try to extract the sheet from the holes.
