Section 7 - Routine Maintenance
If the unit has been in service, turn it off and dis-
connect the power cord connector before proceed-
ing with any maintenance.
7.1 Cleaning the Incubator Interior
Before using any cleaning method except those
recommended by the manufacturer, users must
check with the manufacturer that the proposed
method will not damage the equipment.
Use an appropriate disinfectant. All articles and surfaces
must be thoroughly cleaned, rinsed with sterile water, and
rough-dried.
Alcohol, even a 70% solution, is volatile and flam-
mable. Use it only in a well ventilated area that is
free from open flame. If any component is
cleaned with alcohol, do not expose the compo-
nent to open flame or other possible hazard.
Do not use strong alkaline or caustic agents.
Stainless steel is corrosion resistant, not corrosion-
proof.
Do not use solutions of sodium hypochlorite
(bleach) as they may also cause pitting and rust-
ing.
A HEPA filter replacement kit (see parts list section)
should be on hand prior to cleaning the interior of the incubator.
1. Remove the shelves, access port filter assembly, HEPA
filter and the left and right pilasters. Discard the HEPA
filter and the access port filter assembly.
2. Wash the shelves and pilasters with disinfectant, then
rinse with sterile water. Optional: The shelves and
pilasters may be autoclaved.
3. Wash the inner door gasket with disinfectant. This gas-
ket may be removed to be cleaned, or replaced.
4. Wash the cabinet interior with disinfectant, starting at
the top and working down. Refer to the disinfectant
label for instruction on the length of time needed before
rinsing. Wash the inner door(s) both inside and out. The
cabinet and door must be rinsed with sterile water until
the disinfectant has been removed. After the cabinet has
been rinsed, spray with 70% alcohol.
Some precautions in the cleaning and care of the incubator
glass doors:
Moisture leaches alkaline materials (sodium, Na) from the sur-
face of the glass. Evaporation of the moisture concentrates the
alkaline and may produce a white staining or clouding of the
glass surface. Cleaning chemicals with a PH above 9 and heat
(autoclaving) accelerate the corrosion process. Therefore, it is
very important to rinse and dry the glass doors after cleaning.
Autoclaving the glass doors should be avoided. There is no
simple method for repairing corroded glass. In most cases, the
glass must be replaced.
5. Install the left and right pilasters, inner door gasket and
access port filter assembly, spraying each with 70%
alcohol.
6. Install a new HEPA filter.
7. Install the shelves and spray with 70% alcohol.
7.2 Cleaning the Cabinet Exterior
Clean the incubator exterior with a damp sponge or soft,
well-wrung cloth and mild detergent dissolved in water. Dry
with a soft cloth.
