Forma Series II 3110 Water-Jacketed co2 Incubators User Manual

Incubator Models 3110, 3111 have an operating temperature range of 10
to 55°C, Models 3120, 3121 at 10 to 50°C, and Models 3130, 3131,
3140, and 3141 at 10 to 45°C.  All units require the cooling coil option to
run at any temperature lower that 5°C above ambient. The incubator is
shipped from the factory with a temperature setpoint of 10°C.  At this
setting all heaters are turned off.  
To change the operating temperature setpoint:
1. Press the Mode key until the Set indicator lights.
2. Press the right arrow until Temp XX.X is displayed in the message
center.
3. Press the up/down arrow until the desired temperature setpoint is
displayed.
4. Press Enter to save the setpoint.
5. Press the Mode key until the Run Indicator lights to go to Run mode
or right/left to go to next/previous parameter.
Caution The independent overtemp circuit is designed as a safety to protect
the incubator only. It is not intended to protect or limit the maximum
temperature of the cell cultures or customer’s equipment inside the
incubator if an overtemp condition occurs. 
▲
The incubator is equipped with an independent circuit that monitors the
air temperature in the cabinet.  The independent overtemp circuit is
designed as a safety for the incubator only.  Should the system’s
temperature control fail, this circuit would cut out all heaters when the
cabinet’s temperature reaches the Overtemp setpoint.  When an incubator
is operating in an overtemp condition, the temperature control in the
incubator will be ±1°C around the overtemp setpoint. 
The overtemp’s function is to prevent abnormally high temperatures that
will occur if the heaters are locked on as a result of a failure in the main
temperature control. Although the overtemp circuit will control the
chamber temperature close to the overtemp setpoint, it is not intended to
protect or limit the maximum temperature of the cell cultures or the
equipment inside the chamber when the overtemp condition occurs.

Setpoint
The factory setting for the Overtemp is 40°C.  It can be set over a range of
temp setpoint +0.5°C to 60°C.  If the temperature setpoint is moved above
the Overtemp setpoint, the Overtemp will automatically update to 1.0°C +
the temp setpoint.  It is recommended that the Overtemp setpoint be 1°C
over the temp setpoint.
To set the Overtemp setpoint:
1. Press the Mode key until the Set indicator lights.
2. Press the right arrow until Otemp XX.X is displayed in message center.
3. Press the up/down arrow until the desired Overtemp setpoint is
displayed.
4. Press Enter to save the setpoint.
5. Press the Mode key until the Run Indicator lights to go to Run mode
or right/left to go to next/previous parameter.
All T/C CO
2
cells are precalibrated at the factory at 37°C, high humidity,
and 10% CO
2
. Therefore, if a temperature setpoint of 37°C has been
entered, the humidity pan filled, and the CO
2
control is to run between 0-
10% with a T/C CO
2
sensor,  the CO
2
setpoint may be entered
immediately. Otherwise, it is important to allow the unit 12 hours to
stabilize at the temperature setpoint before entering the CO
2
setpoint.  
All models of the incubator have a CO
2
setpoint range of 0.0% to 20.0%.
The incubator is shipped from the factory with a CO
2
setpoint of 0.0%.
At this setting, all CO
2
control and alarms are turned off. 
To change the CO
2
setpoint:
1. Press the Mode key until the Set indicator lights.
2. Press the right arrow until CO2 XX.X is displayed in message center.
3. Press the up/down arrow until the desired CO
2
setpoint is displayed.
4. Press Enter to save the setpoint.
5. Press the Mode key until the Run Indicator lights to go to Run mode
or right/left to go to next/previous parameter.

Models 3130, 3131, 3140, and 3141 of the incubator have a built-in O
2
control system. The O
2
setpoint range is 1.0% to 21.0%.  The incubator is
shipped from the factory with a O
2
setpoint of 21.0%.  At this setting, all
O
2
control and alarms are turned off. The gas sample port must be capped
when running controlled O
2
levels.
To change the O
2
setpoint:
1. Press the Mode key until the Set indicator lights.
2. Press the right arrow until O2 XX.X is displayed in the message center.
3. Press the up/down arrow until the desired O
2
setpoint is displayed.
4. Press Enter to save the setpoint.
5. Press the Mode key until the Run Indicator lights to go to Run mode
or right/left to go to next/previous parameter.
