The right module is the Night (or low) control. Both the Day and Night modules function in the same way, and the following operation instructions apply to both. - Page 8 lights indicate when the Overtemperature Thermostat has been activated. Under normal operating conditions these pilot lights should never come on. DAY/NIGHT Program Timer: This is a continuous timer with a 24 hour dial divided into two 12 hour sections indicating day and night. This timer switches between the DAY/NIGHT controls.

Page 9: Operation
Section OPERATION The refrigeration system, heater, and air circulating fan are used in conjunction with the temperature control circuit to achieve sensitive temperature control. The thermostat sensor located in the air stream senses any temperature deviation from the control point, and heat is provided to maintain desired temperature. - Page 10 Calibration: It is recommended that calibration is done once the unit is installed in its working environment and has been stabile at set point for several hours. Once it is stabile compare the digital display with the reference thermometer. If there is an unacceptable difference, put the display into calibration mode by pressing both the Up and Down arrow pads at the same time for five (5) seconds until the display begins to blink.
- Page 11 CAUTION: This incubator is capable of safely operating at conditions that might otherwise damage certain accessory equipment. Make absolutely certain accessory equipment is capable of operating under the conditions you intend to run your incubator. 5.10 Exterior Heat: Under normal operating conditions the unit walls may feel warm. This is normal and does not indicate improper performance.

Page 12: Maintenance
Section MAINTENANCE The design of the chamber is such that periodic maintenance is kept to a minimum. NO lubrication or adjustments of components is needed. If the incubator is used frequently at temperatures below ambient room temperature or in any manner that increases moisture build-up within the chamber, a frequent defrosting schedule is recommended. - Page 13 compartment should be vacuumed out at least once every six (6) months to ensure maximum efficiency. Electrical Components: There is NO maintenance to electrical components. If the incubator fails to operate as specified, please review Section 7.0 Troubleshooting, prior to calling for service.
