MAINTENANCE
NOTE: Prior to any maintenance or service on this unit, disconnect the service cord from
the power supply.
8.1 Cleaning: Cleaning and decontamination are recommended on a regular basis. To prepare the
incubator for cleaning remove all interior parts such as the shelf standards and false top. All
stainless steel parts are autoclavable. Please review the Cleaning procedures described in the
Installation section for detailed instructions.
8.2 Check CO
2
supply periodically; don't let it run out. The internal auto tank switch is not alarmed.
8.3 CO
2
supply lines and connections can be checked for leaks with a liquid soap solution. Apply
liquid soap solution to all areas of the supply line and observe for bubbles that will indicate a leak.
8.4 Keep the CO
2
flow system free of impurities. Erratic CO
2
control is usually traceable to the CO
2
pressure regulator on the tank, impurities in the tank, or impurities in the solenoid valve. Replace
the CO2 in-line filters every six (6) months or when the filters have 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.
8.5 If the data logger fails to function as specified, check to verify that the port connections are solid
and not loose. If the data logger still fails to function properly call Customer Service for
assistance.
8.6 There is no maintenance required on any controls. If the controls fail to operate as specified,
please review Section 9.0 Troubleshooting, prior to contacting customer service.
8.7 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
the unit is to be shut down for transport, drain the water jacket, remove humidity pan and shelves,
dry the chamber and disconnect the CO2 and power supply’s. See section 3.3, Lifting / Handling
for transport procedures.
