7.4 Fan Switch
Turn the fan switch on during the warm up cycle for faster heat up time. Also, this switch may be used for rapid recovery. Once the
unit has reached a stable temperature the fan may be turned off.
8.0 Cleaning and Maintenance
Both the interior and exterior of the incubator should be wiped down with a soft cloth periodically to prevent any build-up of dust and grime.
Any spills in the incubator should be cleaned immediately. Cleaning may be performed with a soft, damp cloth. If required, the
chamber may be disinfected. The unit was cleaned at the factory, but not sterilized. Clean the inside of the chamber thoroughly with
a disinfectant that is appropriate to your application. Make sure to rinse the cleaned surface with a damp cloth, using water only,
and dry the surface with a clean cloth. NOTE: Do not use chlorine-based bleaches or abrasives, as this will damage the stainless steel
surfaces. A similar periodic cleaning is recommended.

LABNET 311D AND 611D DIGITAL INCUBATORS
Solution
Controller failed – call Customer Service.
Wiring error – call Customer Service.
Probe is unplugged or broken – call Customer Service.
Recalibrate – see Section 7.2.
Safety set too low – see Section 7.3.
Controller set too low – see Section 7.1.
Unit not recovered from door opening – wait for display to stop changing.
Unit not recovered from power failure or being turned off – incubators will
need 24 hours to warm up and stabilize.
Element failure – call Customer Service.
Controller failure – confirm with front panel lights that controller is calling
for heat.
Safety failure – confirm with front panel lights that Safety is operating
correctly.
Wiring problem – call Customer Service.
Loose connection – call Customer Service.
Ambient temperature is lower than range of unit – compare set points and
ambient temperature to rated specifications.
Sensor is plugged in backwards – call Customer Service.
Confirm that fan is moving.
Confirm that set point is set high enough.
Check if all controller functions work.
Check if the Safety is set high enough – for diagnostics, should be fully
clockwise with the pilot light never on.
Check if the fuse/circuit breaker has blown.
Stabilize ambient conditions – either door opening or room airflow from
heaters or air conditioning. If not the ambient conditions, call Customer
Service.
Calibration sensitivity – call Customer Service.
Safety set too low – be sure that its setting is more than 5°C over desired
set point; check if pilot light is on continuously; turn controller knob
completely clockwise to see if problem solved, then follow instructions in
Section 7.3 for correct setting.
Electrical noise – remove nearby sources of RFI including motors, arcing
relays, or radio transmitters.
