Section 5

Routine Maintenance

1.   Remove the shelves, access port filter assembly, HEPA filter, air sample

filter and tubing, and the left and right duct sheets. Discard the HEPA
filters and the access port filter assembly. See Figure 5-1.

2.   Wash the air sample filter tubing, shelves, and ducts with disinfectant,

then rinse with sterile water. Optionally, the shelves and ducts may be
autoclaved.

3.   Wash the inner door gasket with disinfectant.  This gasket 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 directions for length of time
needed before rinsing. Wash the inner door 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.

5.   Install the left and right ducts, inner door gasket, access port filter

assembly, and air sample filter and tubing, spraying each with 70%
alcohol.  

6.   Install a new HEPA filter.

7.   Install the shelves and spray with 70% alcohol.

Clean the incubator exterior with a damp sponge or soft, well-wrung cloth
and mild detergent dissolved in water. Dry with a soft cloth.
