NOTE: The lid latch must be turned completely clockwise to its stop position in order for the centrifuge to operate. Troubleshooting: 1. 2. 3. 4. 5. 6. 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 The Drucker Company for further assistance. Problem: Excessive noise when the machine is running. Solutions: – Check to see that the load is balanced.

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” × 24”, (with the centrifuge at the center).

Tube Holder Configurations Control Panel: The 642VFD-Plus is capable of spinning test tubes up to 17 mm x 100 mm with its horizontal rotor. Use the following chart and drawing to determine which tube holder and cushion combination should be used with your application. 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 into the six position horizontal rotor: 1.

To change the preset run time, RPM and brake settings: 1. Plug in the line cord. 2. Press the OPEN button to unlock the lid. 3. Open the lid. 4. Press and hold a START button along with the STOP/OPEN button until the latched light begins to flash (approximately 1 second on, 1 second off), then release. 5. Press the same START button once for each minute of run time desired. The time may be set from 1 to 30 minutes. 6. Press the STOP/OPEN button to assign the settings.

To install the rotor: 1. Place the rotor back onto the cone-shaped adapter. You may need to turn the rotor slightly to line it up properly. 2. The rotor should slide onto the rotor cone freely. 3. Once a proper fit has been achieved, replace the rotor nut and turn it until it is hand-tight, (a tool may be required). 4. Replace the tube holders and verify that they are seated properly, (as shown on page 4). 5.
