Maintenance
This section covers routine maintenance. CEM Corporation recommends a routine preventive maintenance to ensure
optimum performance of the Discover SP-D Clinical System.
Interlocks
Weekly, examine the cavity edge and attenuator interlocks to verify that they are clean and working properly. To examine
the interlocks:
1. Turn the Discover SP-D Clinical off.
2. If applicable, remove the attenuator.
3. Inspect the interlocks and verify that they are clean and free of debris.
.
4. If the interlock appears dirty, use a cotton swab and methanol, ethanol, or acetone for cleaning.
5. Once the solvent is dry, the attenuator can be installed.
NOTE: If the attenuator becomes difficult to turn or cannot be locked into position, contact the CEM Service Department
at 800-726-5551 or 704-821-7015 or email service@cem.com.
Cavity
The cavity should be cleaned/inspected if any of the following occurs - vessel Failure, material spilled in cavity, or the
cavity has not been inspected in a week or more. The spill cup protects the temperature sensor from debris in case of a
vessel failure.
1. Turn the instrument off.
2. If applicable, remove the attenuator by rotating it counterclockwise to expose the cavity.
3. Inspect the cavity. If it is clean, proceed to step 10. If the cavity requires cleaning, continue with step 4.
4. Remove the spill cup.
5. Clean the spill cup by rinsing it with water, ethanol, methanol, or acetone. If necessary, the cup can be wiped with a
Soft cloth. Once all debris is removed from the cup, check for cracks and/or damage.
WARNING
Proper precautions must be taken to avoid contact with acids or acid vapors. Protective gear should be worn as
outlined in the user’s safety program for hazardous materials and the reagent manufacturer’s material safety
data sheet. Refer to these guidelines for proper handling and disposal of reagents.
