Drucker Diagnostics Model 842HS Centrifuge - Manual (Page 11)

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 Rotor 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 pathogenic microorganism is spilt in
or on the centrifuge. Small glass fragments left in the rotor after a tube breakage
may adhere to the next test tube inserted in that position. 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. Properly dispose of the
sample and tube fragments and thoroughly clean 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. Must be Lysol (1/4 cup/gallon) or “Cidex”.
Not all Lysol will be sufficient (must be a Lysol Amphyl disinfective cleaner or Virkon). 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.
