Validated disinfection procedures
1
Disassemble the H5i according to the instructions on page 5.
2
Clean all components with a soft bristle brush for one minute while soaking them
in the detergent
1
solution. Pay particular attention to all crevices and cavities.
3
Thoroughly rinse each component according to the manufacturer’s instructions.
4
Perform only one of the following disinfection and drying processes:
5
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.
6
Reassemble the H5i according to the instructions on page 6.
Store in a dry, dust-free environment away from direct sunlight.
Storage temperature: -4°F to 140°F (-20°C to 60°C)
High level thermal
1. Soak the disassembled components in a
hot water bath at pasteurising temperature.
2
Take care that no air bubbles are trapped
against the components.
2. Air dry out of direct sunlight.
High level chemical
1. Soak the disassembled components in a
commercially available solution of a chemical
sterilant.
3
Take care that no air bubbles are
trapped against the components.
2. Thoroughly rinse
4
each component according
to the manufacturer’s instructions.
3. Air dry out of direct sunlight.
1 Cleaning: ResMed has tested the following detergents according
to the manufacturer’s instructions:
– Alconox Tergazyme (diluted at 1%) using hot water (approximately
60°C or 140°F) or warm water (approximately 50°C or 122°F)
– Aniosyme DDI (diluted at 0.5%) using room temperature water
(approximately 20°C or 68°F)
– Neodisher MediZym (diluted at 2.0%) using warm water
(approximately 45°C or 113°F)
2 High level thermal disinfection: Due to specific regional require-
ments, ResMed water tubs have been tested for disinfection for 100
cycles using hot water (approximately 93°C or 199°F) for 10 minutes.
3 High level chemical disinfection: ResMed cleanable water tubs
have been validated for 100 cycles according to the manufacturer’s
instructions using solutions of:
– Ortho-phthalaldehyde 0.55% CIDEX OPA for 12 minutes
– Anioxyde 1000 for 30 minutes
– Sekusept aktiv 2.0% for 30 minutes
4 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.
