5.3 Resin Change - loose resin
NOTE: Pay attention to not overfill the vessel. Only use new, saturated wet resin. Never use
dry resin as this will expand a lot and can damage the system.

Small system: max. 6,25l wet resin
Medium system: max.12,5l wet resin
Big system: max. 25l wet resin
1 cm from the top of the resin to the ledge of the vessel
