WARNING Use universal precautions when handling laboratory specimens. All human specimens of blood, blood compounds, or bodily fluids are potentially biohazardous and may contain Hepatitis B virus, Hepatitis C virus, Human immunodeficiency virus or other disease causing agents. For the safety of both the operator and service personnel, care should be taken when handling substances that are known to be toxic, radioactive, or contaminated with pathogenic microorganisms when using this centrifuge.

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.
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 20” 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 24” x 24”, (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 lid. 2. Insert cushions (if needed) into the tube carriers/holders for the tube size you are using. Refer to ‘Tube Holder Configurations’ for assistance. 3. Place the test tube samples into the tube carriers/holders. Be sure to follow the rules for balanced loads. 4. Close the lid and turn the lid knob clockwise to its complete stop position.
Tube Holder Configurations The next two pages will describe proper balancing and tube loading. Use the appropriate section for the rotor installed in your centrifuge. Improper loading can result in damage to the centrifuge or test tube samples. 6-Place Horizontal Rotor (Standard) This rotor is designed to hold up to six tube holders. It comes with two tube holder types. The red/purple holders are designed to hold tubes up to 10 mL (up to 17 mm x 100 mm).
6-Place Fixed-angle Rotor (optional) This rotor is designed to hold up to six tube holders. It comes with three tube holder types. The black/orange holders are designed to hold tubes up to 15 mL (up to 17 mm x 125 mm). The red/purple holders are designed to hold tubes up to 10 mL (up to 17 mm x 100 mm). The green/blue holders are designed to hold tubes up to 5 mL (up to 17 mm x 75 mm). See page 4 for rotational frequency ratings. Your centrifuge must contain a balanced load in order to work properly.
Troubleshooting: 1. Problem: The rotor does not spin freely. Solutions: • Make sure that nothing has fallen into the rotor chamber. • If there is nothing obstructing the rotor, the motor may be damaged. Contact your authorized dealer or The Drucker Company for further assistance. 2. Problem: There is excessive noise when the machine is running. Solutions: • Check to see that the load is balanced. • Make sure that nothing has fallen into the rotor chamber.
The Horizon Model 642VES complies with all requirements of UL 61010A-1, UL 61010A-2-020, UL 61010A-2-010, UL 3101-2-20, Can/CSA C22.2 No. 1010.1, Can/CSA C22.2 No.1010.2.020 Safety: Horizon Lid Safety Switch: The Horizon lid is secured to the top of the cabinet by a latching knob and pawl system. When the knob is rotated clockwise, the pawl grips the underside of the cabinet opening and prevents the lid from opening. A mechanical stop positions the pawl and prevents it from rotating completely.
