5.7 Set Overtemperture Thermostat: As mentioned in step 5.2, the Overtemperature
Thermostat should be initially set to its maximum position to allow the unit to stabilize.
Once the temperature is stabile at the desired set point, turn the Thermostat
counterclockwise until the OVER TEMP light turns on. Next turn the Thermostat
clockwise just until the pilot lamp turns off. Then turn the Thermostat clockwise two (2)
of the smallest divisions on its scale past the point where the light went out. This will set
the Overtemperature set point at approximately 1

C above the Main Temperature set
point.
5.8 Low Temperature Control: This control is factory set and should NOT be adjusted. It is
pre-set at 1

C and is an added feature that keeps samples from freezing.
5.9 High Temperature Control: Not to be confused with the Overtemperature Thermostat,
this control is factory set and should NOT be adjusted. It is pre-set at 50

C and is an
added feature that will shut down the compressor so that it will not burn up in the event
of a temperature run away.
5.10 Accessory Outlet: There is an electrical outlet inside the chamber for use with
equipment not exceeding one (1) amp. Note that equipment in the chamber may
provide additional heat that could affect the temperature range of the incubator. It is
recommended that testing be done with the incubator and any additional equipment to
insure that the desired operating conditions can be met.
CAUTION: When operating at normal conditions, this incubator is capable of damaging
certain accessory equipment. Make certain that accessory equipment is capable of
operating under the conditions you intend to run your incubator.
5.11 Exterior Heat: Under normal operating conditions the unit will generate enough heat to
be felt by the hand when touching the sides of the unit. This is normal and does not
indicate improper performance.
