electrical current ratings may cause a fire.
Storage Temperature - Storing the LTV
®
1200/1150 ventilator at temperatures above 60°C
(140°F) for long periods can damage the LTV
®
battery and cause battery duration to
degrade.

than 2% glutaraldehyde, phenols, or abrasive cleaners.
Ventilator Immersion - Do not immerse the ventilator in liquids.
High pressure air nozzle – Only a low-pressure air nozzle with flow less than 10 liters per
minute should be used around the ventilator. High pressure can damage the ventilator, in
particular the differential pressure ports.
Front Panel – Do not pour or spray liquids onto the Front Panel.

®
ventilator software is generally designed to be backwards-compatible.
