MAINTENANCE
NOTE: Prior to any maintenance or service on this unit, disconnect the service cord from
the power supply.
7.1 Cleaning: Cleaning and decontamination are recommended on a regular basis. To prepare the
incubator for cleaning remove all parts such as the shelves, shelf standards and false ceiling. If it
becomes necessary to pull out the Lab Stopper on the side of the unit (Part Number 102095), clean
and reinstall the stopper from inside the chamber. All stainless steel parts are autoclavable. Please
review the cleaning procedures described in the Installation section for detailed instructions.
7.2 Check CO

supply periodically and do not let it run out. (Automatic tank switches are available from
your dealer.)
7.3 CO

supply lines and connections can be checked for leaks with a liquid soap solution. Apply a
liquid soap solution to all areas of the CO

supply line and then look for bubbles which will indicate a
leak.
7.4 Keep the CO

flow system free of impurities. Erratic CO

control is usually traceable to the CO

pressure regulator on the tank, impurities in the tank, or impurities in the solenoid valve. Replace the
CO

in-line filter every six (6) months or when the filter has become noticeably dirty on the upstream
side. There is a CO2 filter attached to the tubing kit, and one inside the shadow box connected to
the GAS-IN line.
7.5 Storage: If the incubator is to be turned off for any length of time, dry the chamber and humidity pan
thoroughly and leave at room temperature. Failure to do this may cause the interior to become
contaminated. No adjustment to controls should be required when restarting the unit. If you intend
on shutting the unit down for transport, dry the chamber completely, remove the humidity pan and
shelving, disconnect the CO2 supply and power cord, drain the water jacket and screw in the leveling
feet. See Section 3.3 Lifting / Handling, for transport procedures.
7.6 There is no maintenance necessary for controls. If controls fail to operate as specified, review
Troubleshooting Section, before calling for service.
