AFE ERVICING
Do not modify this instrument without the authorization of a Micromeritics service per-
sonnel.
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
n
electrical components.
High gas pressure (500 psi models only) – high-pressure gas leaks can pose a risk of injury
n
to service personnel.
High temperatures (TEC models only) – temperature controlled components internal to the
n
instrument may be hot and could pose a burn hazard to service personnel.
Protective measures for these risks:
Electrical – the majority of electrical components operate at low voltage (24V or less) and
n
pose low risk when energized. Maintenance, troubleshooting, and repairs should be per-
formed with the instrument de-energized whenever possible, in accordance with standard elec-
trical safety guidelines.
High gas pressure (500 psi models only) – a heavy-duty threaded cap will prevent accidental
n
opening of the chamber during operation. High pressure gas leaks will be indicated by a loud
hissing noise; in this event the gas regulator should be turned off until the leak is corrected.
Ensure the gas regulator is turned off and the gas supply line is vented before disconnecting
the line from the instrument.
High temperatures (TEC models only) – ensure the temperature control is off and verify tem-
n
perature control components are near ambient temperature before servicing.
Verification of the safe state of the instrument after repair:
All instrument panels and covers installed.
n
Gas lines connected and pressurized to normal operating pressure with no leaks.
