6.2 End of the program and removing the objects
– Opening the pressure chamber lid:
Do not lift the safety lever before the
manometer needle is at zero and the
black thermostat indicator has fallen
below 110 °C (230 °F). (Any residual
pressure is blown off against the chamber
lid.) The lid can then be safely unbolted by
pushing the knob to the right and the
chamber lid opened.
– Removing the polymerized objects:
Remove the polymerization container
including the lid from the pressure
chamber and allow it to cool for a few
minutes before removing the polymerized
objects. Cooling too quickly may result in
stress within the resin materials.
– Use softened water (not distilled) or
water 4–9° hard (70–160 ppm/°
US = 5-12° Brit.) (Ph 7–8/20 °C).
If tape water of more than 9° hard (16° Fr)
is used, special care must be given to
maintenance and cleaning or
decalcification (see decalcification,
page 11).
– Make sure that no wax enters the
pressure chamber.
– Set the polymerization time only after
bolting the pressure chamber lid.
– Caution: Do not touch hot parts of
the apparatus during use.
For safety reasons, disconnect power
cord for all cleaning and maintenance
procedures.
7.1 Monitoring and maintenance
Keep pressure chamber sealing rim (5a) and sealing ring
clean and undamaged. If using water as prescribed in
point IV, remove the perforated plate and clean the
pressure chamber, heater, outflow filter, and outflow
system at least every three months. (Remove any wax
residue using a suitable wax solvent.)
7.2 Cleaning
Dust the IVOMAT IP3 from time to time. Use, for
example, a vacuum cleaner with a cleaning brush for
that purpose.

7.3 Maintenance
Please observe the relevant accident control
regulations and other accepted rules regarding
safety and industrial medicine. The connection
cover, which is marked with the rating plate below
may only be opened by a qualified service
technician and with the power disconnected.
Decalcification
If hard tap water of more than 9° (160 ppm/°US = 5–12°
Brit.) is used, the apparatus must be regularly checked,
according to use about once a week, for possible
calcareous deposits on the heating element. For that
purpose, the perforated plate must be removed from the
pressure chamber.
If there is a visible chalky deposit on the heating
element, the device must be cleaned using a deliming
agent as follows: (customary deliming agents used for
coffee makers, boilers, etc. can be used).
