II. CLEANING - MAINTENANCE
III.1. Cleaning
Only the outside of the
MARK 5 Nuvo LITE
is to be cleaned,
with a soft, dry cloth or, if necessary, a damp sponge, then
thoroughly dried with wipes and an alcohol based solution.
Acetone, solvents or any other in ammable products
must
not be used
. Do not use abrasive powders.
The removable Cabinet Air (dust) lter (2) must be cleaned
weekly in warm water and household detergent or after
approximately 100 hours of use. More frequent cleaning is re-
commended in dusty enviroments. Dry before reinstalling.
a. The following minimum guidelines should be
observed:
• Humidi er:
(If prescribed by a physician)
Clean according to the manufacturer's instructions. If no
instructions are provided, do the following:
Daily:
- Empty the water from the humidi er.
- Rinse the humidi er ask under running water.
- Fill humidi er up to the mark with distilled water.
Regularly:
- Disinfect the humidi er parts by immersing them in a
disinfectant solution (in general, we recommend using a
solution of 1 part vinegar diluted with 10 parts water).
- Rinse and dry.
- Check that the humidi er lid seal is in good condition.
• Oxygen tubing and nasal cannula:
Follow the manufacturer’s instructions.
b. For each new patient:
Follow the instructions from the humidi er manufacturer.
The
MARK 5 Nuvo LITE
cabinet should be cleaned and
disinfected as per the above instructions. The cabinet air
lter should be washed or replaced. The entire oxygen ad-
ministration circuit (oxygen therapy nasal cannulas, etc.)
must be changed.
III.2. Daily disinfection
Due to the presence of the nal product lter <0.3 µm inside
the device, everyday disinfection concerns only the external
oxygen therapy accessories: humidi er, probes, nasal can-
nulas (refer to the respective instructions for use).
The device must be switched off when alcohol based
solutions are used.
