Altering the standard working temperature (continued)
• To fill the wax baths, use wax pellets or paraffin which has already been
liquefied.
• Place the wax bath onto the corresponding station holder and push the
cable into the notch at the edge of the platform.
Check for each wax bath whether it is actually installed at same station
number it is connected to at the rear of the instrument.
Do not overfill the wax baths!
The level of the liquid paraffin must not exceed the upper fill level
mark on the inside of the wax bath.
When filling the station, make sure the paraffin level is not below
the minimum level in which case there is a risk that not all speci-
mens will be entirely immersed in paraffin and thus will not be infil-
trated completely.
It may take several hours to liquefy solid paraffin. Make sure to cal-
culate the waiting time! When refilling wax pellets, again make
sure to observe the waiting time for complete liquefaction.
The wax bath rims and sealing rings of the lids always have to be
clean and undamaged.
The covers must close tightly, as for instruments with vacuum func-
tion, the vacuum would not be able to be built up.
