Operation
3. When the COOL position is employed, place the WATTAGE switch
in the "Off" position.
Allow the chamber temperature to decrease to within 5°C of the desired
temperature; then select the appropriate heater wattage.
Desired Chamber
Wattage Setting Temperature °C
700 5 to 20
1400 21 to 37
All Models
Deviations from the above temperature wattage recommendations may be
necessary, due to low voltage, extreme ambient conditions, or unusually
large loads. For these conditions, select the wattage which allows an
approximate 50% heating cycle [Heat "On” (Control Pilot Lamp "On”)
50% of the time, and "Off" 50% of the time]. With each wattage setting,
allow the unit to operate for at least 30 minutes; then determine the
percent of heat cycle.
Setting the SAFETY and CONTROL Thermostats:
For Model 30M:
1. Using a small screwdriver, turn both the temperature control and
safety temperature thermostat adjustment screws fully clockwise. The
temperature control pilot lamp should now be illuminated.
2. When the incubator reaches the desired temperature, slowly turn the
safety thermostat adjustment screw counter-clockwise unitl the safety
pilot light is illuminated.
3. Turn the safety thermostat adjustment screw approximately ¼ turn in
a clockwise direction. The safety thermostat light should now be off.
The thermostat is now set a few degrees above the desired incubator
temperature.
4. Turn the Control thermostat adjustment screw counterclockwise until
both pilot lamps are off. Next turn the control thermostat adjustment
screw clockwise until the control pilot lamp just comes on.
5. Allow the unit to stabilize then readjust or fine tune the control
thermostat as necessary. The chamber temperature is stabilized when
the Control pilot light cycles (50% of the time on and 50% of the
time off).
