1. Circuit Breaker The Model GF614B has a 4 Amp circuit breaker at the rear of the base that disconnects power in the event of an overload preventing the device from operating GF614B Centrifuge 8 OPERATION Note Follow the previous Initial setup procedure before initial operation l Ensure that the centrifuge s power cord is plugged into a properly grounded 115 Volt AC 60 Hz electrical wall outlet Turn the latch counter clockwise and open the lid Place the test tube samples into the tube holders Be sure to follow the rules for balanced loads Close the lid and turn the lid knob clockwise to its com plete stop position Turn on the device by turning the timer to the desired run time 7 The centrifuge should begin to spin Once the timer reaches zero 0 the motor will stop and the rotor will coast to a stop Do not open the lid until the rotor has come to a complete stop Turn the lid latch knob counter clockwise and open the lid 10 Remove the samples 11 The centrifuge is immediately ready for operation GF614B Centrifuge MAINTENANCE With proper care and maintenance your centrifuge will pro vide years of laboratory service For proper care always follow the maintenance instructions in this section Z WARNING Electrical shock hazard Do not open the case Any disassembly of the device must be per formed by a qualified service technician Provide Adequate Ventilation2. Place the centrifuge on a hard smooth surface for good air circulation For cooling purposes the centrifuge draws in ambient air through the air intake cover on the top of the lid and exhausts this air in the rear of the base Spin Balanced Loads Ensure that you always spin a balanced load The Model GF614B has a unique counter balanced motor mount de sign which along with its rubber suction feet produces excellent vibration dampening However out of balance loads may break glass test tubes and or produce unsatis factory separation results Proper load balancing will help to improve sample separation and extend the life of the centrifuge Refer to earlier SETUP Balanced loads section for additional information on balancing the load GF614B Centrifuge 10 Keep the Tube Holders Clean Z WARNING NOTE Always follow the safety guide lines of materials in the event that a substance known to be potentially toxic radioactive or contaminated with a pathogenetic microorganism is spilled in or on the centrifuge Small glass fragments left in the tube holder after a tube breakage may adhere to the next test tube inserted in that holder When this tube is handled these fragments may puncture protective gloves and lacerate the operator s fingers or hand Remaining fragments may provide stress points on subsequent tubes and result in additional breakage If a tube breakage occurs carefully remove the tube hold er Properly dispose of the
