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 24” 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 30” x 30” (with the centrifuge at the center).
(Continued) 9. 10. 11. 12. 13. 14. 15. 16. 17. If this is a variable speed version, turn the speed control to MAX. Turn the centrifuge on by pushing the ‘START’ button. The ‘RUN’ indicator light will illuminate. The unit will accelerate to its set speed. Listen to the sound of the centrifuge. A smooth whirring sound should be heard. If there are any loud or unusual sounds, stop the centrifuge by pushing the ’OPEN / EMERGENCY STOP’ button immediately and refer to page 12 on troubleshooting.
2. Change the Run-Time Preset: NOTE: The centrifuge must be plugged in and the lid must be opened to access programming functions! a. Push and hold both the ‘START’ and ’OPEN / EMERGENCY STOP’ buttons for approximately three (3) seconds. The ’LATCH’ indicator light will begin to flash; indicating program mode. Release the two buttons. b. Press the ‘START’ button once for each minute of desired run time. The ‘RUN’ indicator light will flash once for each entered minute. c.
BALANCED LOADS Your centrifuge must contain a balanced load in order to work properly. To ensure that the load is balanced, keep these rules in mind when inserting test tube samples: 1. 2. 3. Opposing tube carriers must be identical. Opposing tube carriers must be empty or loaded with an equal number of equally weighted samples. If an odd number of samples is to be spun, use a water-filled tube to mate with the unpaired one.
Tube Holder Configurations: 12-Place or Fixed Angle only Your Horizon Model 755 centrifuge can spin various test tube sizes ranging from 1.5mL to 15mL, (up to 125mm, (4.9 in.) in length), with the appropriate accessories. Use the following chart and drawing to determine which tube holder and cushion combination should be used with your application. DIRECTIONS: 1. Compare the tube to be spun with the four boxes shown below. 2. Find the box that most closely matches the tube’s length.

Care and Preventative Service: 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 rear of the lid and exhausts this air out the rear of the base. Do not block the rear of the centrifuge as this will not allow the machine to properly ventilate itself. 2.
(Continued) 7. Remove Accessories Before Moving: All tube holders, samples, and caps must be removed from the rotor chamber before transporting or storing the centrifuge to prevent damage and injury. Before using any cleaning or decontamination methods except those recommended by the manufacturer, users should check with the manufacturer that the proposed method will not damage the equipment. See page 15, Step 5, for the recommended cleaning solutions.
The Horizon model 755 complies with all requirements of UL standard 61010A-1, 61010A-2-20; Can/CSA C22.2 No’s 1010.1; 1010.2.20. 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.
Troubleshooting: 1. Problem: The rotor does not spin freely. Solutions: - Make sure nothing has fallen into the rotor chamber. - If there is nothing obstructing the rotor, contact your authorized dealer or The Drucker Company for further assistance. 2. Problem: 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.
