5.4 Leveling
The unit must sit level and solidly. Leveling feet are supplied and must be installed in the four holes in the bottom corners of the unit.
With the feet installed and the unit standing upright, each foot can be raised by turning it in a counterclockwise direction. Adjust the
foot at each corner until the unit stands level and solid without rocking. If the unit must be moved, turn the leveling feet all the way
clockwise to prevent damage while moving.
5.5 Cleaning
The unit chamber should be cleaned and disinfected before use. Remove all of the interior parts, and clean thoroughly with a
disinfectant that is appropriate to your application.
NOTE:
Do not use chlorine-based bleaches or abrasives as this will damage the
chamber interior. Regular periodic cleaning is required.
6.0 Controls
1. Power switch:
The main power ON/OFF switch controls all power to the unit. The power must be On before any systems are
operational. The green switch will be lighted when ON.
2. Main temperature control:
This control consists of the digital display and Up/Down buttons for inputting set point temperatures
and calibration.
3. Safety thermostat:
The Safety is completely independent of the Main Controller. The Safety guards against any failure of the Main
Controller that would allow temperature to rise past set point. If temperature rises to the safety set point, the Safety takes control
of the heating element and allows continued use of the incubator until the problem can be resolved or service can be arranged.
4. Fan switch:
This operates the turbo fan inside the chamber for fast heat up times and recovery. The switch is lighted when
activated.
5. Safety light:
This pilot light comes on when the Safety thermostat is activated. Under normal operating conditions this pilot light
should never be on.
7.0 Operation
Check power supply against unit serial plate. They must match. Plug the power cord into the electrical outlet.
Push power switch ON, and turn the Safety thermostat to its maximum position, clockwise.
7.1 Set Main Temperature Control
Enter desired set point temperature. To enter set point mode on the control, press either the Up or Down button one time. The digital
display will start to blink, going from bright to dim. While blinking, the digital display is showing the set point. To change the set
point, use the Up and Down buttons. If the buttons are not pressed for five (5) seconds, the display will stop blinking and will read
the temperature of the unit.
NOTE:
The Safety thermostat should be turned to its maximum position, until the unit has stabilized at
desired set point temperature. Allow the incubator at least 24 hours to stabilize.
7.2 Calibration
The Main Temperature Controller was calibrated at the factory at 37°C; however, it is recommended that calibration is done
once the unit is installed in its working environment and has been stable at set point for several hours. Place a certified reference
thermometer in the chamber. Be certain the thermometer is not touching any shelving. Allow the temperature to stabilize again
until the thermometer reads a constant value for one hour. 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 buttons at the same time
until the two outside decimal points begin to flash. While the decimal points are flashing the display can be calibrated by pressing
the Up or Down arrow buttons until the display reads the correct value. Allow the incubator temperature to stabilize again, and
recalibrate if necessary.
7.3 Set Safety Thermostat
As mentioned above, the Safety thermostat should be initially set to its maximum position, to allow the unit to stabilize. Once the
incubator is stabile at the desired set point, turn the Safety thermostat counterclockwise until the Safety light turns on. Next, turn
the thermostat clockwise just until the Safety light turns off. Then turn the thermostat clockwise two (2) of its smallest divisions on
its scale past the point where the Safety light went out. This will set the Safety thermostat at approximately 1°C above the main
temperature set point.
