Removing the Nebulizer

Charged Aerosol Detectors (VH-D20, VF-D20)
Operating Manual
CAUTION—Sharp Tip of the Nebulizer
The capillary inside the nebulizer that protrudes from the nebulizer tip is
sharp and may be fragile. Touching the nebulizer capillary can cause
personal injury and damage to the capillary.
• To avoid personal injury, always wear safety glasses when handling
the nebulizer.
• Do not touch the nebulizer tip.
• Handle the nebulizer with care.
CAUTION—Escaping Gas
Gas can escape from open gas connections when the detector gas flow
and/or the gas supply is turned on. The escaping gas can pose a health
and safety risk.
• Make sure that the detector gas flow and the gas supply are turned
off before you remove the nebulizer, disconnect the gas tubes or
remove the gas filter assembly from the detector.
• Turn on the gas supply and detector gas flow only when the
nebulizer is installed, the components in the gas flow path are
properly connected, and the protective cover of the gas filter
assembly is installed.
NOTICE
The nebulizer is highly sensitive to contamination. Even minute particles
on the nebulizer can lead to contamination and poor detector
performance. Always wear powder-free gloves when you install or
remove the nebulizer.
