Safe Servicing
Do not modify this instrument without the authorization of a Micromeritics service personnel. |
To ensure safe servicing and continued safety of the instrument after servicing, service personnel should be aware of the following risks:
Product specific risks that may affect service personnel:
- Electrical. Servicing or repair could require opening the outer panels and exposing energized electrical components.
- Liquid nitrogen. See Dewar Precautions.
- Elevator. Could pose a pinching hazard when lowering. Maintenance may require the elevator screw to be greased. The service engineer can use a manual switch on the elevator assembly to cycle the elevator to distribute the grease to permit safe servicing and continued safety of the equipment after servicing.
Protective measures for these risks:
- Electrical. The majority of electrical components operate at low voltage (24V or less) and pose low risk when energized. Maintenance, troubleshooting, and repairs should be performed with the instrument de-energized whenever possible, in accordance with standard electrical safety guidelines.
- Elevator. Moves very slowly. It is normally operated from the computer attached to the instrument so the operator is physically distanced from the instrument. The safety shield door of the instrument should be closed during elevator operation. Use of the manual switch on the instrument requires particular attention and care by the service personnel.
Verification of the safe state of the instrument after repair:
- Elevator must be in the down position.
- Sample tubes must be removed to prevent accidental breakage. Ports should be capped (recommended).
- Safety shield door is closed (recommended).
