The only regular maintenance required for your unit is
to keep it clean and free from contamination. Use the
guidelines and instructions in this section to maximize
the life
of your incubator and help prevent
contamination of your samples.
WARNING
Do NOT Use Flammable Cleaning Detergents.
Do NOT store Flammable materials In, On or Near
this equipment.
Disinfecting Your Unit
Although your operating conditions and related protocol
should
determine the actual decontamination
procedures you use, always keep the following
guidelines in mind when decontaminating your unit:

Use cleaning materials known to be
compatible with your unit. If any questions
arise about compatibility issues, contact
Customer Service, see page-21.
 Clean and disinfect the incubator interior on a
regular basis. If the inside of your incubator
smells strangely or contains rust, mold, or dirt,
you need to clean your incubator more
frequently
 Dust the outside walls of the incubator at least
every two months.
 For incubators placed on the floor, move the
incubator every two months to clean and
disinfect the floor below.
 Clean all gaskets and hinges every month.

Do not use chlorine-based bleaches or
cleaners with abrasives as they will corrode
and pit the interior of you incubator and any
other stainless steel surfaces. Use only non-
abrasive cleaners.

Do not use spray cleaners that might leak
through openings and cracks and get on
electrical parts. These cleaners may also
contain solvents that will harm the coatings.
 Do not use hard tools such as metal wire
brushes or steel wool. Use only soft tools such
as plastic brushes.
 Do not depend on the use of antibiotics to
maintain completely sterile conditions, as this is
an inadequate technique for sterilization.
Instead, use the aseptic techniques described
in this section to maintain sterile conditions in
the incubator.

You can use an autoclave to decontaminate
stainless
steel parts by following the
manufacturer’s instructions.
Otherwise, wash all parts and surfaces with
soap and water to remove any organic material.
Disinfect the parts with a 70% alcohol solution.
Rinse with distilled water and wipe dry with a
soft cloth.
