Preventive Maintenance - Thermo Scientific 3110 Operating And Maintenance Manual

Your equipment has been thoroughly tested and calibrated before shipment. Regular preventive maintenance is important to keep your unit
functioning properly. The operator should perform routine cleaning and maintenance on a regular basis. For maximum performance and efficiency, it
is recommended the unit be checked and calibrated periodically by a qualified service technician.
The following is a condensed list of preventive maintenance requirements. See the specified section of the operating manual for further details.
We have qualified service technicians, using NIST traceable instruments, available in many areas. For more information on Preventive Maintenance
or Extended Warranties, please contact Technical Services.
Cleaning and calibration adjustment intervals are dependent upon use, environmental conditions and accuracy required.
Tips for all incubators:
Do NOT use bleach or any disinfectant that has high chlorine content.
Use water with characteristics as described in Filling Water Jacket.
Avoid spraying cleaner on the CO
Do not use powdered gloves for tissue cultures.
Action
Check CO and/or N tank levels (tanks without optional gas guard monitor)

Inspect the inner and outer door latches and hinges for proper operation and excessive
mechanical wear; inspect the line cord insulation and inner door silicone gasket for
chips and cracks. Replace as required.
Check water level in humidity pan, ½" from top. See "Filling the Humidity Pan".
Check proper blower motor operation (air flow, noise, and vibration)
Verify and document CO , humidity and temperature calibration, as applicable. See
