8.1.4 Repair-related cleaning
If needed, follow these general guidelines when cleaning the ventilator during servicing.
Procedures for periodic cleaning and sterilization of the ventilator and accessories are given
in the
700 Series Ventilator System Operator’s Manual
. Specific procedures for periodic
cleaning and inspection done during the ventilator’s performance verification are given in
Chapter 5 of this manual.
• Clean ventilator exterior surfaces before disassembly. Use isopropyl alcohol, a bactericidal
agent, or a mild detergent and warm water solution, and a clean, lint-free cotton rag.
Allow cleaned ventilator parts and surfaces to air-dry. The use of solvents and harsh
cleaning detergents is not recommended.
• Vacuum ventilator interior using ESD-safe equipment. Do not clean ventilator interior
with high-pressure air.
• During disassembly, clean parts as necessary with isopropyl alcohol. Replace any parts that
cannot be cleaned.
8.1.5 Electrical cables and pneumatic tubing
• To ensure proper reassembly, note or label wire or tube positions before disconnecting
parts.
• When pulling silicone tubes off fittings, pull gently while turning to avoid shredding the
tubing.
• Make sure all tubes and harnesses or cables are reinstalled using cable ties, as specified.
Make sure wiring does not interfere with and cannot be damaged by hinged or moving
ventilator parts. Make sure that the grounding harness is replaced to the oxygen
regulator.
8.1.6 Adhesive use
• When installing a part to be attached with adhesive, first remove the adhesive residue
using a suitable scraping tool that won’t scratch the ventilator surface. Clean scraped
surfaces thoroughly with isopropyl alcohol. Be sure the application area is free of dust and
grease, then press on item, ensuring adhesive contact and bonding. Eliminate any trapped
air bubbles.
• Be careful when using any cleaners and solvents, as these may cause personal injury or
damage to ventilator surfaces. Use in a well ventilated area.
• Replace any damaged warning and caution labels using the removal and installation
techniques described above.
Warning
The failure to replace damaged warning, caution, and identification labels may result
in personal injury, equipment, or property damage.
