Model 3010 Incubator __________________________________________________________________Maintenance
Section 4: Routine Maintenance
Before using any cleaning or decontamination
method except those recommended by the
manufacturer, users must check with the
manufacturer that the proposed method will not
damage the equipment.
4.1 Disinfecting the Incubator Interior
If the units have been in service, dis-
connect the power cord connector
before disinfecting.
Use an appropriate disinfectant. All articles and surfaces to
be disinfected must be thoroughly cleaned, rinsed and rough-
dried.
Alcohol, even a 70% solution, is volatile and
flammable 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.
Allow the alcohol to fully dry before turning
power on.
Do not spray the T/C sensor with flammable solu-
tions. The internal temperature of the CO
2
sen-
sor is approximately 150°C when the unit is in
operation. Allow sufficient time for the sensor to
cool before cleaning.
Do not use strong alkaline or caustic agents.
Stainless steel is corrosion resistant, not corrosion
proof. Do not use solutions of sodium hypochlo-
rite (bleach), as they may also cause pitting and
rusting.
1. Turn the incubator off and disconnect the plug from the
power source.
2. Remove the shelves, access port filter and side duct
sheets. Remove the temperature sensors and the air sam-
ple filter tubing from the back of the blower scroll.
Refer to Figure 4-1.
3. Remove the filter from the air sample filter tubing.
4. Remove the wingnuts securing the top duct to the interi-
or. Carefully slide the top duct down and off the temper-
ature sensor, air sample filter tubing.
5. Wash the shelves, ducts, wingnuts and stopper with dis-
infectant and rinse with sterile water. Option: Autoclave
shelves, ducts and wingnuts.
6. Remove the blower scroll by first pushing the black
lever clip closest to you toward the scroll. Then turn the
scroll to the right to disengage it from the blower scroll
plate. Some manipulation may be required as the align-
ment holes are keyhole-shaped.
7. Remove the remaining wingnut, then pull down on the
blower wheel. If a new wheel and scroll are going to be
used, discard the old ones. If the old ones are being
reused, wash all parts with disinfectant and rinse with
sterile water.
8. Remove the blower scroll plate by first pushing the
black lever clip toward the chamber ceiling. Then turn
the plate to the left to disengage it from the alignment
keyholes. Clean as above, or autoclave.
9. Wash the cabinet interior with disinfectant starting at the
top and working down. 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.
10. Reinstall the blower scroll plate by aligning it with the
larger end of the keyholes and turning it to the left to
lock it on. Pull the black lever clip downward from the
ceiling.
11. Install the blower wheel onto the
motor shaft, aligning the d-shaped
flat sides of each. See Figure 4-2.
Secure the blower wheel with the
wingnut. Make sure the wheel turns
freely.
12. Locate the blower scroll over the
blower wheel into the larger end of
the keyholes on the scroll plate. Turn the scroll to the
right to lock it into the keyholes. Pull the black lever
clip closest to you toward the front of the unit.
