Safety instructions ­ safety regulations on the instrument itself Safety · This device may only be used by trained laboratory technicians. It may only be used according to its intended use and the instructions in this instruction manual. · 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. Nonobservance can cause accidents, injuries and/or damage to the instrument/accessories. Safety instructions ­ transport, installation and operation · After unpacking the instrument it may only be transported in an upright position. · Before connecting the device to a power source, ensure that the voltage indicated on the type plate matches the voltage available at the place of installation. The unit must be connected only with the supplied power cable and only to a grounded power receptacle. · The minimum voltage (see specifications) must be maintained while starting the refrigeration unit. The compressor needs a starting current of approx. For correct operation, a consistent power supply conforming to the instrument's specifications is required. Please ensure that your electrical installation fulfills these preconditions prior to installing the unit. Nonobservance causes damage to the instrument. · Switch off the instrument each time before servicing, repairing or cleaning, and pull out the power plug. 2. 3 Built-in safety devices Automatic circuit breaker in the main switch Shortcircuit · An automatic circuit breaker with a lit switch is located in the main switch. This circuit breaker separates the unit from the mains power supply in the event of a short-circuit. · In this case, the main switch jumps to the position "0" = Off. Fig. 2 Leica EG115 0 C 7 3. Instrument components and specifications 3. 1 Overview ­ instrument parts · The instrument is distinguished by a simple, modular design and a powerful refrigeration unit with precisely controlled cooling performance. · High temperature consistency ensures homogeneous blocking out and prevents tearing of the paraffin blocks. · High cooling performance ensures that the instrument's working temperature is reached quickly. · Optimized temperature distribution in the cold plate prevents dripping condensation. · The generously-dimensioned cooling surface has room for around 70 blocks. · Designed for use with the Leica EG1150 H paraffin embedding station.
