8.3 Technical malfunctions

Error or malfunction
1. Objects not fully cured, even though
the program ran normally (Timer
has run to "0", manometer shows
"0").
2. Program fails to continue after
polymerization time has been set.
3. Automatic program has stopped
too soon (Timer has not run to "0",
manometer indicates pressure).
4. Pressure falls abnormally slowly
after the end of the program.
(Manometer shows "0", timer has
run to "0". Polymerization
temperature has been reached.
Possible causes
– Too little water in the
pressure chamber, or
– temperature too low, or
– time too short, or
– air pressure too low
Chamber lid not properly closed
and bolted.
No or far to little water in the
pressure chamber (excess heat
protection of the heater
engaged).
Heater and overheating sensor
in the chamber very dirty or
calcareous.
Power failure or defective fuse.
Outflow filter in the pressure
chamber is partly blocked.
Outflow system partly blocked.

Corrective action
1a) Repeat program (polymerization) with
sufficient water, correct temperature and
time, and stipulated air pressure.
2a) Close and bolt chamber lid according
to the instructions.
3a) Disconnect power. Release pressure by
means of the safety valve. Turn air knob
(16a) at the end of the safety valve (16)
counter-clockwise until the manometer
indicates "0" and the black needle on the
thermostat registers less than 90 °C/194 °F.
Open the chamber lid and allow chamber
to cool for approx. 6 min. Then, turn air
knob clockwise until it stops. Press red
reset button (17) on the back of the
apparatus.
3b) Proceed as described in 3a). Remove
perforated plate from the pressure
chamber and clean it. Clean heater with
overheating sensor and clean or delime the
chamber according to the service
recommendations.
3c) See point 7.
4a) Remove perforated plate from the
pressure chamber. Clean outflow filter,
chamber, and heater, or delime according
to the service recommendations.
4b) Clean sound absorber (23). Unscrew
water drain hose (18) from the back of the
apparatus and blow compressed air
through the hoses. Delime if necessary.
