31 Leica EG1150 H – Paraffin Embedding Station
5. Operation
Enhanced mode
A large amount of heat is needed for melting paraffin. This is only account-
ed for in standby mode for a respective preliminary time. In the operating
mode, the paraffin reservoir is heated just enough to maintain the paraffin
at the selected temperature. Therefore the melting process can be sped
up by increasing the heat supply (enhanced mode) whenever necessary
(e.g. when solid paraffin has to be added to the reservoir when working in
shifts). The paraffin reservoir is then heated for a period of four hours to a
higher temperature (enhanced mode).

Advance times
To ensure that the instrument is ready (all working temperatures reached)
at the programmed start time, the various sections are activated in advance
as follows:
Paraffin tank:
Heating starts 4 hours before working time begins.
Work top: Heating starts 4 hours before working time begins.
Dispenser tube: Heating starts 1 hour before working time begins.
Cooling spot: Cooling starts 1 hour before working time begins.
During the heating phase, the display reads - - : - - ; the colon flashes in
intervals of seconds.
The advance times cannot be modified.
To activate the enhanced mode, push and hold
the and buttons simultaneously.
The brief lighting up of all four target value
LEDs of the paraffin reservoir confirms that the
on-demand heater has been activated. In other
words, the buttons have to be held until all 4 LEDs
light up.
The selected set value LED flashes while en-
hanced mode is enabled.
The enhanced mode can be switched off at any
time by pressing and holding the same key com-
bination. Deactivation of the on-demand heater
is also confirmed by all four target value LEDs
lighting up.
