BEFORE COMMENCING OPERATION
Initial cleaning method
Before using the incubator for the first time, clean dirt (tape residue, smear, etc.) from the
chamber and the inner attachments thoroughly.
Keeping the chamber clean is essential for efficient performance. Clean the chamber and
all the inner attachments at least once a month. Use the following steps to clean the
incubator properly.
When these steps are not sufficient to remove dirt, contact our sales representative
or agent.
1.
Remove the inner attachments, referring to “Removing inner attachments” on pages 21
~22.
2.
Clean the inner attachments, the chamber inside walls, and the inner door gaskets with a cloth or
sponge soaked in neutral detergent, diluted by 5 % or less (Fig. 1). (Undiluted detergent can damage the
plastic components. For the dilution, refer to the instructions on the detergent.)
CAUTION
Do not use detergents or antiseptic solutions with acid, alkali, or chlorine. Doing so may cause
discoloration, corrosion, or rusting.
Be careful to keep the diluted detergent or water out of the temperature sensor, the CO
2
gas injection hole,
the fan motor shaft bearing, and the inner sample air outlet (marked on Fig. 2 by ). Also, do not wash
the temperature sensor, CO
2
sensor and the UV lamp using detergent. Doing so may cause failure.
3.
Soak a piece of gauze or unwoven cloth in distilled water, wring it out and wipe off the residual detergent
thoroughly.
4.
Wash the two silicon caps for the access port and the fan using the detergent and rinse them with
distilled water, and then autoclave them for sterilization (121
o
C, 20 minutes).
5.
Wipe the inside walls and the inner attachments thoroughly with an unwoven cloth soaked in alcohol for
disinfection. Be careful not to leave any alcohol residue.
6.
Reinstall the inner attachments correctly and securely, referring to “Installing inner attachments” on page
23.
