Decontaminating Before the disinfection process, each component must be cleaned and rinsed so no visible contamination is present. 1. Clean all components with a soft bristle brush for one minute while soaking them in the detergent solution. Pay particular attention to all crevices and cavities. 2. Thoroughly rinse each component according to the manufacturer’s instructions. ResMed has tested the following detergents according to the manufacturer’s instructions:
Detergent
Water temperature
Alconox™ Tergazyme (diluted at 1%)
Hot water (approx 140°F or 60°C)
Aniosyme™ DDI
Warm water (approx 122°F or 50°C) Room temperature water (approx 68°F or 20°C)
(diluted at 0.5%) Neodisher MediZy™ (diluted at 2.0%)
Warm water (approx 113°F or 45°C)
Disinfecting In the procedures below, only one disinfection or sterilization procedure needs to be performed: • High level thermal disinfection • High level chemical disinfection • Sterilization.
High level thermal disinfection 1.
Soak the disassembled components in a hot water bath at 194°F (90°C) for 1 minute. Take care that no air bubbles are trapped against the components. 2. Air dry out of direct sunlight. High level thermal disinfection equivalent water bath parameters:

High level chemical disinfection 1.
Soak the disassembled components in a commercially available solution of a chemical sterilant. Take care that no air bubbles are trapped against the components. 2. Thoroughly rinse each component in drinking quality water (five litres per assembly) by immersing it completely for a minimum of one minute in duration. 3. Repeat the rinse procedure two additional times using new drinking quality water for each rinse, for a total of three rinses. 4. Air dry out of direct sunlight. ResMed cleanable water tubs have been validated for 100 cycles according to the manufacturer’s instructions using solutions of:
Chemical
Process Time
Ortho-phthalaldehyde 0.55% CIDEX™ OPA
12 minutes
Anioxyde™ 1000
30 minutes
Sekusept aktiv 2.0%
30 minutes
Sterilization The H5i cleanable water tub and air outlet have been validated for 100 cycles for sterilization by STERRAD™ 100 S, STERRAD 100 NX and STERRAD NX.
Inspecting Perform a visual inspection of all components. If any visible deterioration is apparent (cracking, crazing, tears etc), the water tub should be discarded and replaced. Slight discoloration of the silicone components may occur and is acceptable.

Reassembling the H5i When all the parts are clean and dry, reassemble the H5i as follows: 1. Reinsert the air outlet ensuring that the straight side is facing up. 2. Place the outlet clip back onto the air outlet. Ensure that the outlet clip goes past the ridge on the air outlet. 3. Reinsert the maximum water level mark into the plate ensuring that it clicks into place. 4. Place the plate back onto the base ensuring that the maximum water level mark faces up. 5. Place the tub lid back onto the plate/base ensuring that the center holes are aligned. 6. Clip all four side latches. 7. Fill the water tub and return the water tub to the H5i. 8. Close the flip lid ensuring that it clicks into place.
Packaging and storage Store in a dry, dust-free environment away from direct sunlight. Storage temperature: -4°F to 140°F.
