1. Important notes
1.2 Specified use and application
The Leica EG1150H is a modern paraffin embed-
ding station with microprocessor control.
It is designed for embedding histological tissue
specimens in molten paraffin for use in patholo-
gy laboratories and only for the following tasks:
• Melt solid paraffin for sample embedding
and maintain the molten paraffin at the re-
quired temperature.
• Fill the molds, in which the tissue specimens
were placed, with paraffin.
• Heat and maintain the temperatures of em-
bedding cassettes with specimens and
molds as well as the required forceps.
Any other use of the instrument will be
considered as improper use!
1.3 User group
• The Leica EG1150H may only be operated by
qualified personnel.
• The user must read the operating instruc-
tions supplied and be familiar with all the in-
strument’s technical details before any work
on the instrument can be carried out.
1.4 Instrument type
All information in this instruction manual applies
only to the instrument type indicated on the title
page.

2. Safety
Be sure to comply with the safety instructions and warnings provided in this chapter.
Be sure to read these instructions, even if you are already familiar with the operation and
use of other Leica products.
2.1 Safety notes
This instruction manual contains important
instructions and information regarding the
operational safety and maintenance of the
instrument.
The instruction manual is an important part of
the product, which must be read carefully prior
to start-up and use and must always be kept
near the instrument.
If additional requirements on accident
prevention and environmental protec-
tion exist in the country of operation,
this instruction manual must be
supplemented by appropriate instruc-
tions to ensure compliance with such
requirements.
This instrument has been built and tested in ac-
cordance with the safety regulations for electri-
cal measuring, control, regulating and laborato-
ry devices.
To maintain this condition and ensure safe op-
eration, the user must observe all notes and
warnings contained in this Operating Manual.
For current information about appli-
cable standards, please refer to the
CE declaration for the instrument and
to our Internet site:
http://www.leica-microsystems.com
The protective devices on both instrument and accessories may neither be removed nor modi-
fied. Only service personnel qualified by Leica may repair the instrument and access the
instrument’s internal components.
2.2 Warnings
The safety devices installed in this instrument by the manufacturer only constitute the basis for
accident prevention. Primarily responsible for accident-free operation is above all the owner
of the instrument and, in addition, the designated personnel who operates, services or cleans
the instrument.
To ensure trouble-free operation of the instrument, make sure to comply with the following
instructions and warnings.

2. Safety
Safety instructions – safety regulations on the instrument itself
Safety regulations marked with a warning triangle on the instrument itself mean that
when operating or exchanging respective parts of the instrument, the correct operating
steps as described in the instruction manual supplied, must be adhered to. Non-obser-
vance can cause accidents, injuries and/or damage to the instrument/accessories.
Certain surfaces of the instrument are hot during operation under normal
conditions. They are marked with this warning sign. Touching these surfaces
can cause burns.
Safety instructions – transport and installation
After unpacking the instrument it may only be transported in an upright position.
Place the instrument on a laboratory table and adjust it to a horizontal position.
The instrument must not be exposed to direct sunlight (window)!
Plug the instrument only into a grounded mains socket. The protective effect may not be
eliminated by an extension cable without a protective grounding conductor.
The instrument automatically recognizes the applied voltage/frequency.
The installation location must be well-ventilated; there should be no ignition sources
there of any kind.
The instrument may not be operated in hazardous locations.
Extreme temperature fluctuations between storage facility and setup site as well as high
humidity may cause condensation to form. In this case, wait at least two hours before
switching on.
Safety instructions – working with the instrument
Paraffin is flammable and should therefore be handled with due care. Do not use sharp
tools to remove solidified paraffin from the work areas, as this may destroy the coating on
the surface. Use the plastic spatula supplied with the instrument.
During operation, the paraffin reservoir, mold warmer, cassette warmer, work area as
well as the forceps holder are hot.
Risk of burning!
Do not store any combustible and flammable substances near the instrument. There is a
fire hazard if work with an exposed flame (e.g. Bunsen burner) is carried out in the direct
vicinity of the instrument (solvent vapors). Therefore a minimum safety distance of 2
meters must be adhered to!

2. Safety
Hazards – servicing and cleaning
Switch off the instrument each time before servicing and pull out the mains plug.
When using cleaners, please comply with the safety instructions of the manufacturer and
the laboratory safety regulations.
Before changing defective fuses, the instrument has to be disconnected from the mains.
Only fuses that are easily accessible may be replaced by the user.
Set the standby switch to “Standby“ ( ) when replacing the halogen lamp and pull the
power cable out of the mains socket.
During operation and cleaning, do not allow any liquid to penetrate inside the instrument
and the transporting arm.
2.3 Built-in safety devices
The instrument is equipped with the following safety features and devices:
Fuses in the heating elements
All resistance mats of the instrument are equipped with overheating fuses,
which switch the heating element off if overheated.
Automatic circuit breaker in standby switch
An automatic circuit breaker is located in the standby switch. This circuit
breaker separates the power electronics from the mains power supply in
the event of a short-circuit.
In this case, the standby switch jumps to the position “0“ = Off.
Note that the only way the user has for complete disconnection from the mains supply is
disconnection of the mains plug.
