SETUP LOCATION: 1. Unpack the centrifuge and verify that all of the supplied equipment is present. 2. Choose a setup location which meets the following criteria: a) A bench top clearance height of 40 cm is required in order to open the lid. b) The clearance envelope is the space around the centrifuge which is required for safety. Choose a setup location which will allow for a clearance envelope of at least 61 x 61 cm, (with the centrifuge at the center).
OPERATION: NOTE: Follow the initial setup procedure before initial operation. 1. Press the ‘OPEN / STOP’ button to unlock the lid and then open the centrifuge lid. 2. Turn rotor lid knob counterclockwise, and remove rotor lid. 3. Place the test tube samples into the rotor. Be sure to follow the rules for balanced loads. 4.

MEMORY LOCATIONS / STORING AND RECALLING: The Hematofuge 842HS centrifuge is capable of storing up to 10 user-defined presets.These memory presets contain all of the settings needed to define a specific run, (run time, speed, acceleration rate, braking rate, etc.). The user can use these memory locations to quickly configure the centrifuge for a specific test type and ensure that the test is run in the same way each time by recalling this same setting. Store a configuration in a memory location 1. 2. 3.
CARE AND PREVENTATIVE MAINTENANCE: With proper care and maintenance your Horizon centrifuge will provide years of laboratory service. For proper care, the following steps should be taken: 1. Provide Adequate Ventilation: For cooling purposes, the Horizon 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. The centrifuge should be placed on a hard smooth surface for good air circulation. 2.
TROUBLESHOOTING: 1. Problem: Solutions: 2. Problem: Solutions: 3. Problem: Solutions: The rotor does not spin freely. • Make sure that nothing has fallen into the rotor chamber. • If there is nothing obstructing the rotor, the motor may be damaged. Contact your authorised dealer or The Drucker Company for further assistance. There is excessive noise when the machine is running. • Check to see that the load is balanced. • Make sure that nothing has fallen into the rotor chamber.
SAFETY: The Hematofuge 842HS complies with all requirements of CE EN 61000-3-2, -3-3, EN 61000-4-2, -4-3, -4-4, -4-5, -4-6, -4-11, EN 61010-1, -2-020 and UL standard 3101–2–20, Can/CSA C22.2 No. 1010.1 , Can/CSA C22.2 No. 1010.2.20 Horizon Lid Safety Switch: The Horizon lid is secured to the top of the cabinet by a locking knob and pawl system.
