Option 2 (Manual Cleaning and High-Level Chemical Disinfection)

Disassembly	Disassemble the humidifier water chamber according to the “Disassembling and Reassembling”
	instructions on page 5.
Pre-cleaning	Rinse all water chamber components 10 times and brush thoroughly with a soft bristle brush in a
	warm (113°F or 45°C) solution of Alconox (1%).

Cleaning	1. Clean all components of the water chamber with a soft bristle brush for one minute while
	soaking them in the detergent1 solution. Pay particular attention to all crevices and cavities.
	2. Thoroughly rinse each component according to the manufacturer’s instructions.
Drying	Allow the water chamber to air dry out of direct sunlight.
Pre-disinfection	Not applicable.
Drying	Not applicable.
Disinfection	1. Soak the disassembled water chamber components in a commercially available solution of
(high-level	ortho-phthalaldehyde 0.55% (eg, CIDEX™ OPA)2. Take care that no air bubbles are trapped
chemical	against the components.
disinfection)	2. Thoroughly rinse	3	each component according to the manufacturer’s instructions.
Drying	Air dry out of direct sunlight.
Inspection	Perform a visual inspection of the water chamber. If any visible deterioration is apparent (cracking,
	crazing, tears etc), the water chamber should be discarded and replaced. Slight discoloration of the
	silicone components may occur and is acceptable.
Reassembly	Reassemble the humidifier water chamber according to the “Disassembling and Reassembling”
	instructions on page 5.
Packaging &	Store in a dry, dust-free environment away from direct sunlight.
Storage	Storage temperature: -4°F to 140°F (-20°C to 60°C).

1 Cleaning: ResMed has tested the detergent Alconox (diluted at 1%) using hot water (approximately 140°F or 60°C) or warm water (approximately 120°F or 50°C) according to the manufacturer’s instructions.

2 Disinfection: ResMed water chambers have been validated for 20 cycles using solutions of ortho-phthalaldehyde (0.55% CIDEX OPA for 12 minutes) according to the manufacturer’s instructions.

3 Rinsing: Thoroughly rinse each component in drinking quality water (five litres per assembly) by immersing it completely for a minimum of one minute in duration. Repeat the rinse procedure two additional times using fresh water for a total of three rinses.
