Cautions

CAUTION
Electrical Grounding –Loss of protective ground could result in electrical shock. Only use
®
the unmodified power supplies and cords supplied for the LTV 1200, 1150, or 1100
ventilator, maintained in good condition and connected to a properly wired and grounded
electrical power outlet.
Fuse Fire Hazard – Replacement of existing fuses with fuses of different voltage or
electrical current ratings may cause a fire.
®
Storage Temperature - Storing the LTV 1200, 1150, or 1100 ventilator at temperatures
®
above 60°C (140°F) for long periods can damage the LTV battery and cause battery
duration to degrade.
Patient Assist Call Connector – Do not apply more than 25V rms or 32VDC to the Patient
Assist Call connector.
CLEAR Function Cautions - The CLEAR function should be used with great care as once
a section of the memory is cleared, all data in that section of memory is lost and it cannot be
automatically restored.

Electronic and Mechanical Parts - The LTV 1200, 1150, or 1100 ventilator contains
delicate electronic and mechanical parts that must be handled properly to avoid damage.
Follow the instructions given in this manual carefully and make sure to observe all
instructions.
Opening the ventilator - Always turn the ventilator OFF and remove the external power
before opening the ventilator case or attempting to service the ventilator.
Anti-static Precautions - Always wear a grounded anti-static wrist strap when handling the
ventilator with the case open. Electrostatic discharge can damage the internal electronics.
Verification of Operation - After opening the ventilator and performing any maintenance,
verify proper operation of the ventilator by performing the checks and calibrations
recommended in Chapter 9 - Final Checkout Test.

do not use cleaning agents containing ammonium chloride, other chloride compounds, more
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.
®
Care of Bacterial Filters – If bacterial filters are used in conjunction with the LTV 1200,
1150, or 1100 ventilator, comply with all recommended care procedures as specified by the
filter manufacturer.
®
Wet or Damp Filters - Do not install any wet or damp filters into the LTV 1200, 1150, or
1100 ventilator. This could damage the ventilator.
Software Version – Never install a version of software lower than that originally installed in
®
the ventilator. Erroneous operation may result from use of incompatible software. LTV
ventilator software is generally designed to be backwards-compatible.
