CAUTION Hot surface. The external surface of the spray insert, API source housing,
and entry to the ion transfer tube can become hot enough to burn your skin. Before
you touch or remove heated parts, allow the part to cool to room temperature
(approximately 20 minutes) before you touch it.
CAUTION
• Make sure that you do not accidentally lift the release lever that is located above
the API source interface, which will vent the mass spectrometer.
• To avoid contaminating the ion transfer tube, do not touch its exposed entrance.
