Drucker Diagnostics Model 842VES Centrifuge - Manual (Page 13)

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. Always Spin Balanced Loads: This centrifuge is equipped with imbalance detection.
However, it is still possible to run loads that are minimally imbalanced, particularly at an
imbalance setting of LOW SENSITIVITY. For maximum centrifuge life, set the imbalance
detection to HI SENSITIVITY and always run balanced loads. Refer to pages 8 and 9 on for
additional information on balancing the load.
3. Keep the Tube Holders Clean: NOTE: Always follow the safety guidelines of your
laboratory to properly clean up and/or dispose of materials in the event that a substance
known to be potentially toxic, radioactive or contaminated with a pathogenetic
microorganism is spilt in or on the centrifuge. Small glass fragments left in the tube carrier /
holder after a tube breakage may adhere to the next test tube inserted in that carrier /
holder. When this tube is handled, these fragments may puncture protective gloves and
lacerate the operator’s fingers or hand. Remaining fragments may provide stress points
on subsequent tubes and result in additional breakage. If a tube breakage occurs,
carefully remove the tube holder. Properly dispose of the sample and tube fragments and
thoroughly clean both the inside and outside of the tube carrier / holder. Insert a new tube
cushion (if necessary) and replace the tube carrier / holder in the rotor.
4. Motor and Electrical Maintenance: This centrifuge uses a brushless-DC motor. There
are no brushes to replace and it should not need routine servicing for the life of the
centrifuge. The electrical components are selected for high reliability and should not need
service.
5. Keep the Centrifuge Clean: The cabinet, rotor top and accessories shall be thoroughly
cleaned using either isopropyl alcohol, soap and water, or a mild bleach solution. The use
of Fully/Partially Halogenated Hydrocarbons, Ketones, Esters and all other chemicals not
prescribed by the manufacturer may cause damage to the rotor and tube carriers / holders
and shall not be used. 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
If it is necessary to remove the rotor for additional cleaning it is required that a qualified
technician remove the rotor assembly.
Apply cleaning solutions with a towel or cloth. Do not submerge the centrifuge in water or
other cleaning solutions as this will cause damage and void your warranty!
If hazardous material is spilt on or inside the centrifuge, the centrifuge must be decontaminated.
6. Tube Holder Replacement: It is recommended that the tube holders be replaced after 24
months or 25,000 cycles, whichever comes first.
