9. When set the OTL system prevents runaway heating in the event of a failure of the microprocessor controller or its thermometer probe while the TEC H is heating the chamber The OTL does this by depowering the TEC H heating circuits whenever the temperature in the incubation chamber exceeds the OTL setting This provides a limited protection against heat damage to samples Typically the OTL is set 1 C above the digital controller temperature set point Because of its nature as a mechanical system and its lack of PID analytics the OTL cannot deliver the same degree of temperature stability and measurement precision as the digital controller The OTL System should only be used as a means of heating regulation for the incubation chamber until a failed controller or its thermometer probe can be repaired or replaced The OTL will not prevent a rise in heat caused by a complete failure of the Pletier TEC H itself With the loss of the chilling function the chamber temperature will rise to the ambient room temperature plus 1 or 2 C 21 Page LAB OPERATION CONTINUED Note Setting up the incubator for use in a new workspace environment requires an 8 period for the unit to come up to temperature and sit undisturbed This is done to achieve thermal stability Thermal stabilization at the operational set point is necessary to achieve an accurate on site temperature calibration See the Calibrating the Temperature Display procedure on page 24 fo

14. ATOR Humidification should not be needed for closed bottle BOD applications Placing only a small number of open or breathable media containers in the incubator chamber may lead to excessive drying of sample media Unusually dry environmental conditions may also contribute to sample drying To counteract this Sheldon Manufacturing offers an optional humidity collection pan and tubing accessory kit Part Number 9900708 The kit redirects moisture that normally condenses on the heat sink fins of the Peltier TEC heating and cooling device and uses it to humidify the incubator After ordering and receiving the kit place the stainless steel pan on the lowest chamber surface Connect the tubing that comes with the kit to the port on the back of the Peltier duct cover Run the tubing down the back of the incubator behind the shelves and secure the end of the tubing inside the pan The pan is supplied with a copper slug to help prevent microbial contamination The humidification kit is intended for use while running small loads 29 Page LAB OPERATION CONTINUED MANAGING CONDENSATION Excessive condensation in the incubation chamber may create leaks around the chamber door and may cause corrosion damage if allowed to continue for significant lengths of time Condensation appears wherever the humidity level in the incubator chamber reaches the dew point The dew point is the level of humidity at which the air cannot hold more water vapo
