Drucker Diagnostics Model 755 Centrifuge - Manual (Page 9)

8 99
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). No person or hazardous material shall be permitted in the
clearance envelope during operation. The operator time within the
envelope shall be limited to the time necessary for loading, unloading and
centrifuge operation only.
c) Proper ventilation is necessary to prevent the overheating of samples as
well as premature failure of the centrifuge. Choose an area which will
allow unencumbered air flow.
d) No adjustment is necessary for leveling the centrifuge, however,
the surface should be flat and level.
e) Be sure the outlet is always within reach as the line cord is
the means of emergency disconnection!
Initial Setup Procedure:
If any problems are found during the initial setup procedure, refer to the
troubleshooting section on page 12.
1. Plug the line cord into the rear of the centrifuge. Plug the other end into an
approved electrical outlet. For electrical safety, the unit must always be
properly grounded.
2. Engage the power button on the front of the centrifuge (lower left-hand
side). The button will be illuminated when it is activated.
3. For safety purposes, the locking system is always activated. To
deactivate the system (in order to insert or retrieve samples) press the
‘OPEN / EMERGENCY STOP’ button on the control panel. The
‘UNLOCKED’ indicator light should illuminate. If it does not, refer to page
12 on troubleshooting. The lid will be unlocked for 15 seconds after pushing
the ‘OPEN / EMERGENCY STOP’ button.
4. Turn the latch counter-clockwise and open the lid.
5. Spin the rotor by hand; check for free and level rotation. If the rotor does
not spin freely, refer to page 12 on troubleshooting.
6. Check the thumb screw in the middle of the rotor and make sure that it is tight.
7. Place the test tube carriers inside the rotor and verify that they are seated
properly.
8. Close the lid. Rotate the lid knob clockwise to its complete stop position.
The ’LATCH’ indicator light should be illuminated. If it is not, make sure that
the lid is latched properly. The centrifuge will not run unless the lid is
latched and the ’LATCH’ light is on.
