11. Care and maintenance
Generally disconnect the unit from
mains supply before executing care
and maintenance.
Ideally cleaning is to be effected dryly
with a soft piece of cloth, if necessary
with a slightly humid sponge and a mild
cleaning liquid. Water and cleaning
liquids must not get into the unit.
The O-rings should be greased regularly
with silicone grease. Removal and cleaning of the filter
sieve
Disconnect the power cable from the
socket and shut down the compressed
air supply. Push the blue ring of the
compressed air connection upwards and
draw the hose off the unit by pulling it
downwards. Now unscrew the connec-
tion using a suitable tool. Then carefully
remove the filter sieve with a slotted
screwdriver by turning anti-clockwise.
Clean with stream of compressed air
and reassemble in reverse order.
10.3 Fabrication of cast form parts
With the K-7 insert it is possible to
thermoform up to 7 resin bases for
the crown and bridge technique at the
same time.
Fix the single dies by means of a flexible
blocking out material (e. g. Fillin) in the
holes of the K-7 insert.
Remove the nub plate from the F insert
(6) and replace it by the K-7 insert.
All further working steps as described
