Important Note: For electrical installation and checkup as mentioned below, always involve a certified electrician for power requirements. We also strongly recommend that a trained engineer install and check out your Beckman Coulter Optima L ultracentrifuge, and train your staff on the proper usage of the ultracentrifuge and rotors prior to use.

Power:

a. Check for correct wall receptacle and voltage at the outlet. Power required is 180 to 264 Volts AC measured as shown. It is advisable to test the line voltage at the plug while the instrument is accelerating and cooling; therefore, we would strictly recommend that the ultracentrifuge always be installed by a Beckman trained engineer. Service AI has Beckman Coulter trained service experts. You can email us at support@serviceai.us, or call us at our technical support line at +1-510-899-1340 for more information.

b. Remove console cover, front panel and top cover.

c. Make sure jumper connector on the power supply boards plugged into the correct voltage range socket J52 A, B, or C. (Select the jumper for the lowest voltage reading during maximum power consumption.)

J52 VOLTAGE RANGE

A 180 - 206

B 207 - 233

C 234- 264

Physical Installation Procedure:

a. Position ultracentrifuge in desired location. Maintain 6" minimum clearance at rear and 3" minimum clearance at each side.

b. Position the four pads provided under the leveling legs. Mark the position of each pad on the floor.

c. Roll out instrument away from pads.

d. Glue (epoxy) pads to floor.

e. Roll instrument back into position and screw the four leveling legs down into the pads until they have bottomed out.

f. Now screw each leveling leg down five additional turns. Make sure all four casters are off the floor.

NOTE: A solenoid inter-lock prevents the chamber door from being opened during operation and/or with the power off. The chamber door can be opened with the door handle only when the power to the ultracentrifuge is on and the vacuum is off.

g. Open the chamber door (see note above). Level the ultracentrifuge as if it had only three legs. Adjust level by placing the spirit level on the drive shaft (crown) and adjust the leveling legs so the air bubble is centered. First level it front- to- rear by adjusting the left front and left rear legs. Then level it left to right by adjusting the right front leg only. (Make sure you do not tilt the instrument). Screw in the right rear leg until it just touches the pad. Now screw it down 1/4 turn more. This does not affect the level of the instrument.

h. After instrument is leveled, make sure all four casters are off the floor and all four leveling legs are still bottomed out.
