User Guide STP420D/STP420ES
The STP420 has four paraffin containers, situated in the upper part
of the instrument behind the processing chambers. The containers are
constantly heated as long as the instrument has power.
Each container is marked with 'silver ring' fill lines: to use one chamber
only, fill the containers to the lower line. You must fill both paraffin
tanks up to the line in order to use the two chambers simultaneously.
Heating is applied to the containers from below, and via a heating
core in the middle of each container. The initial paraffin melts, with
the entire volume melting in approximately nine hours. Subsequently,
melting takes approximately four hours.
You can clean the drain mesh or remove objects that fall into the tank
when you lift the heat distribution device. First, drain the paraffin from
the tank to avoid dirt getting into the filter system.
