To prevent contamination, do not reuse paraffin collected in this tray. If the instrument is operated without the paraffin collection trays there is risk of burning. 17 16 Mold warmer and cassette warmer (16) Depending on the preferred working direction, the two heated trays can be used for molds or cassettes (6, 7). The temperature is adjustable between 55 °C and 70 °C. A removable receptacle (16) can be placed in each of the trays. A lid (17) is provided for each of the trays (16) to prevent loss of heat and contamination inside the tray. For easy access, the lid can be opened and folded back. Fig. 11 When working with half-open lids (17), raise the temperature one level to ensure that the paraffin remains molten. Only operate the cassette and mold warmer and paraffin reservoir with lid; otherwise the set temperature cannot be maintained. 20 Instruction Manual V 2. 2, Rev B ­ 12/2009 5. Operation 21 8 Standby switch (8) After the unit has been commissioned, the standby switch should only be used if the unit is to be switched off for a longer period of time. In daily routine operation, the ON/OFF button on the control panel should be used. Pressing the ON/OFF button (20) switches the instrument into active standby mode. All displays are switched off, only the LED (21) of the ON/OFF button remains lit. If programmed procedures are to be carried out: the standby switch (8) must be switched on and the unit must be in standby mode. For more information, see Chapter 5. 4. 9 20 18 19 Fig. 12 Work area illumination (9) A halogen lamp provides homogeneous diffuse illumination of the embedding area and refrigeration spot. This gives an optimum view of the embedding process and tissue orientation. The lamp should be adjusted in a way that it is switched on and off only with the lamp button on the control panel. For this purpose, turn the cap (18) in the position where the two "I" "I" marks (19) are located one above the other. To access the halogen bulb, the cap (18) can be removed. (For replacement of the halogen lamp see Chapter 7. 2) Leica EG1150H ­ Paraffin Embedding Station 21 5. Operation Foot switch (22) optional 22 The foot switch (22) actuates the magnet valve of the dispenser. It must be connected as described in Chapter 4. 6. The plug of the foot switch MUST be screwed onto the socket. Otherwise hot paraffin may escape even when the foot switched is not being pressed. 11 14 12 Pressing the foot switch opens the valve, releasing it closes it. This keeps the operator's hands free to work with the instrument. [. . . ] 23 Leica EG1150 H ­ Paraffin Embedding Station 35 7.
