5.3.4 Overtemperature Setting
The overtemperature (OT) is set according to solvent used. See table 3.
Maximum temperature possible to set:
OT 145 -----> 115 °C
OT 210 -----> 185 °C
OT 330 -----> 285 °C
Warning
The overtemperature setting should always be checked for each
solvent used. Our recommendations are selected according to the
ignition point figure that was available at the time when this
manual was written. To be sure, you are advised to check the spe-
cific safety data sheet for the solvent to be used.
Note: The temperatures listed in the table below are given for
guidance only; they may have to be adjusted for factors like
room temperature, water temperature, heat transfer from hot
plate to cup, etc.
A good temperature is when the drop rate is approx. 3-5 drops
per second.
