By purchasing a product you have decided on a high quality product. Please read these operation instructions carefully before and during using this device for the first time to achieve good results from the very beginning.

Connect the compressed air hose supplied to the compressed air network ( at least 3 bar ). The pressure in the comressed air network must never exceed 3 bar otherwise a pressure reducer (available separately on request ) must be installed between the compressed air network an the compressed air hose supplied. Access to the roomin to which the Polyvessel used must be restricted to authorised, trained members of staff. Always comply with pressurised container legislation and general accident prevention instructions when handling the Polyvessel.

Fill the Polyvessel with water to approximately 3 - 5 cm below the rim.
Heat the filled
Polyvessel to the required temperature of 35-40° using the Polyvessel (available separately on request ). This is carried out automatically with item No. 11 110 once the hot plate has been switched on.

Warm water previously heated to 35 - 40° can be poured into the pot instead of heating the water.


  • Place the lid on the rim of the pot by scewing the bayonet closure firmly into position.
  • Ensure that the left marking line on the lid coincides whit the large bolts on the pot handle.
  • Turn the swich to the ON “/“ position.
  • Push the lid handle over the pot handle.
  • Turn the swich OFF “0“.
  • Fill the pan with compressed air via the comressed air hose supplied by applying pressure to the plug nipple on the lid inlet valve (2.0 -2.2 bar ).
  • The pot cannot be opened in the “0“ position.
  • The pot is pressurised for approximately 30 minutes until the plastic has completely hardened.
  • Before the total polymerisation time ( 30 minutes ) has elapsed, the Polyvessel can be briefly opened to insert other objects. The previous item must, however, remain pressurised for at least 5 minutes.


  • Set the swich to the ON “/“ position.
  • Air is expelled.
  • Wait until the air has been completely expelled.
  • Turn the lid handle to the right until it locks into position and lift off.

To check the safty valve, fill the
Polyvessel to the rim with water every month, close the lid and stop (place switch in CLOSED “0“ position). Place the device under pressure; the safety valve must open between 2.6 and 2.8 bar. If the valve does not open, change the safety valve or send the entire Polyvessel system to the manufacturer for repair.

In accordance with safety regulations, the complete system, i. e. lid and pot, must be checked and if need be, repaired by the manufacturer. Despite the corrosion-resistant coating, the device should be cleaned regularly both inside and outside. This will prolong the useful life of the Polyvessel device.

Depending on the frequecy of use, the rubber seal should last for at least 1 year. To change the lid sealing, remove the old ring from the nut and insert the new ring in the four opposite  spaces on the nut. The ring initially seems to big.

Press the rubber ring around and into the nut until it sits tightly. Lubricate the ring in advance with Vaseline. Talcum, glycerine or Vaseline is recommended for cleaning purposes.

N. B.
In order to retain the protective effect of the pan`s Teflon coating, we recommend that you change the water reularly

(ideally drain in the evening) since, despite its high quality, the linning may be damaged by liquid that has meanwhile developed aggressive properties.

Thanks to its safe and tried-and-tested construction, the
Polyvessel guarantees a bubble and pore – free hardening of the polymerisate. Please comply with the following instructions stictly as directed in order to guarantee durable quality and safety when processing plastics in the Polyvessel device.
