Danger!
Warning against damage and injury.
1. The electrical supply circuit to the incubator must conform to all national and local electric
codes. Check the serial-data plate for voltage, cycle, phase and amperage requirements before
you connect the unit.
2. Only use grounded power source (outlet) to avoid an electric shock or fire.
3. In case of a problem, do not attempt to repair the product yourself. Do not open the power box
to avoid electric shocks.
4. Do not pull out the plug when the unit is in use. Never drag on the wire to unplug the unit.
5. A separate branch circuit is recommended to prevent loss of samples due to overloading or
failure of other equipment on the same circuit.
6. A surge protector is recommended to avoid power-related faults.
7. In case of malfunction or burning smell, the unit must be unplugged immediately .Use a circuit
breaker to cut off the power supply. Continuance of abnormal state will end up with fire as a
result of overheating.
8. The electric power supply must be cut off in following situations:

Attention!
Instructions for optimal performance
1. The unit must be placed horizontally on a solid, flat floor or table.
2. The incubator needs even heat lost on all surfaces in order to maintain small internal
temperature variations. As a result, a minimum of 20 cm must be allowed between the rear and
sides of the incubator and any walls, partitions or obstructions to facilitate adequate convection
of air around the unit.
3. Do not locate the unit exposed to direct sunlight or near heating /cooling ducts.
4. The unit must be kept away from electromagnetic interference sources.
5. Culture placed inside the incubator should be placed to the extent of which the air flow inside
the incubator is not affected to maintain the temperature uniformity in the working chamber.
6. Make sure the shelves inside the chamber are placed horizontally.
7. Slam the door(s) will probably leads to damage of the equipment.
8. When in operation, do not open the door (too much or too long) as this might affect the
temperature inside.
9. The incubator must be kept away from volatile, flammable, explosive liquids or gases.
10. Please keep the chamber clean. Regular cleaning is required.
11. After transport of the Incubator – DO NOT USE IT for at least 24 Hours, unless you are a
100% sure that the unit has been moved in an upright position only.
12. If the incubator is used continuously at low temperatures, condensate can occur inside of the incubator. You might need to wipe this
out, or-if possible-heat up the incubator to evaporate the condensation.
There is however on the right side (low) a drain that might be emptied.
(see the picture).
13. To extend the compressors life and maintain an excellent performance of your refrigeration system, the condenser of the unit should be
cleaned every month.

1. Performance Features
 Both the interior and exterior are made of robust materials for lifetime operations. The inner
chamber is made of high quality #304 stainless steel sheets, with 4 round coved corners. All
exposed edges are de-burred to insure no sharp edges. The exterior is cold rolled steel
finished with powder coated polyurethane finish, which is resistant to most chemicals and
easily cleaned with mild household detergents.
 The INCU-C BOD incubator microprocessor temperature control systems all use fast
responding PT 100 sensors which commands and executes a special control algorithm that
energizes a solid-state switch to supply power to the heaters.
 The compressor system runs at all times-(except for higher internal temperatures). If cooling
is required, a solenoid valve –also driven by the microprocessor-will be activated and cool
down the incubator to the required temperature.
 The 3 dimensional air circulation, motor fan speed adjustable in three steps via the controller ensures optimum temperature distribution across the internal chamber.
 The control electronics are protected through a circuit breaker that may trip at 110% of
loading rate, but will trip within 1 second at 150% of load rating.
 Space-age high density material is used to insulate the inner chamber walls.
 All electrical components are fully accessible after removing the top-cover.
 The inner glass door is 3/16” tempered with smooth-ground edges, and seals are tight
against a U-grooved door rubber gasket.
 A fluorescent light is installed as standard, for medium intensity of illuminating needs in the
chamber.
 A magnetic gasket on the outer door helps to insure a tight seal against the cabinet.
 A double-layered observation window comes as standard on every INCU-C Series Incubator.

2 grid shelves, 50mm test port, RS232 interface on the side wall as standard, built-in printer,
UV light as options available upon request.

the “Increase” and / or “Decrease” button to set the desired time.
7.5 Every time the “Set” button is pressed, the programmed value of the parameter is
stored and the next item is asked for, so the next parameter is the (Ramp End)
Temperature that the incubator has to reach for in the first segment (S1).
7.6 Press the “Decrease” or “Increase” button to set this temperature parameter for
segment 1.
7.7 Press SET to store and to set the “Temperature Hold” time. (The length of time that
the incubator has to maintain the (Ramp End) Temperature for this Segment 1); Use
the “decrease” and/ or “increase” buttons.
7.8 Press SET to store and enter the next segment (S2) setting process.
7.9 Press increase or decrease button to enter the second Ramp Time (S2)
And so on…….
7.10
You can terminate the program setting by choosing “end” or “cycle” in any of
the 10 segments. To do so, press the Decrease key- Lower than (below) 0.00 in the
“Hold Time” of designated segment.
 “End”. First the screen asks: “end”, which means the whole program terminates here
and the unit stops working.
 “Cycle”. If you keep pressing the Decrease (key) again, it will ask for: “cycle” that
means this is the end of the program and unit will restart the whole program.
7.11
After the last segment, the display asks for the “Hold Deviation”. This is the
temperature deviation that the incubator may have at the end of each” Ramp” before
starting the Hold Time, in another word, the difference between actual temperature
and desired “Ramp End Temperature”, which activates the Hold Time. If it’s set as
“0”, “Hold Time” will start counting down as soon as the “Ramp Time” dues. Otherwise, the "Hold Time" will remain on hold until the temperature reaches the value of
"Ramp End Temperature"+/- "Hold Deviation".
7.12
The last parameter is called “Cycle” meaning the number of programmed cycles the incubator must repeat. (max. 99 times). If “Cycle” is set to 1, the run is repeated 1 time, so a total of 2 times!

8.3 Power-off Recovery
This unit has power-off recovery function. When after a power failure, the equipment will
automatically recover to run according to the originally designed program.
No setting is required
8.4 Cooling System & Defrosting Settings
-Cooling Control Setting
The cooling system can be set to run automatically, continuously on , or off for the best
performance of temperature control. The factory default setting is "AUTO", but can be
changed to "ON", or "OFF" if needed.
-Auto Defrosting Setting
This unit is equipped with automatic and manual defrosting functions.
For automatic defrost, it is effective only when the cooling system is in operation, and
the actual temperature value is lower than 15℃.The unit will run auto defrosting cycle
according to the following two parameters settings,
Defrost Timer—Auto Defrost Cycle
This function indicates the time interval between two defrosting cycles. The set range is
between “0-240” hours. Set it as “0” to disable the auto defrosting function. Once the
“defrost timer” is set, the unit will automatically perform the defrosting cycle accordingly.
To find out the suitable "defrost timer" setting, the frosting time duration should be
counted from start of the low-temperature operation to the point that the actual temperature start bouncing up due to the frosting inside the evaporation chamber. Then set
the "defrost timer" as somewhere between 1/10-1/5 of the frosting time duration. For
example, if the frosting time duration is 20 hours, the "defrost timer" can be set from 2-4
hours. High relative humidity will require more frequent defrosting cycle.
Defrost Period/Time
This function indicates the time duration for each single defrost cycle both under auto
and manual operations. The set range is between “1-24” mins Set it as “0” to disable the
defrosting function.
When the ambient temperature is higher than 25℃, like in summer, the recommended
setting is 30 seconds, otherwise, 1 min is considered as adequate. As ambient conditions may vary, therefore, always try to find the most appropriate settings for your own
particular ambient condition.

10.Electric Inputs & Outputs
11 . Temperature Calibration.
Attention:
1. The unit is delivered with calibration done in the factory, so please
perform the calibration only if necessary. It's recommended the unit is
calibrated once a year or two years.
2. If the unit is running at one set point in most time, perform one point
calibration as 11.2.
3. To get a linear temperature in the chamber, a 2 point calibration must be
executed.
11.1 Take a certified calibrated thermometer in a small bottle with glycerin and place that
in the geometrical center of the incubator.
Low Temperature Point Correction (0.0)
11.2 Change the set point to the value that the unit is most frequently used for, or a lower
point, for example, 8.0°C and let the incubator run for at least 1 hour– until the
temperature is constant, and let the temperature inside of the chamber uniform.
11.3 Open the outer door and read the temperature on the thermometer through the inner
glass door; calculate the difference with actual displayed temperature. for example, if
reading is 6°C, difference would be 6-8= -2°C, while if reading is 9°C, the difference
would be 9-8=1°C
11.4 Press the SET button and go with the up arrow to code “47”.
11.5 Press the SET again, to enter the Step 1. "Low Temperature Point Correction (0.0)",
the display shows the "Temperature Correction" with "0.0" and the "Current Correction Value". Use the up and/or down key to make a further adjustment on the current
correction value by the temperature difference calculated above, for "-2°C ", decrease by 2, for "1°C ", increase by 1.
22
INCU-C Series V2018.1.1
11.6 Keep pressing "SET" button, skip the " High Temperature Point Correction (100.0)"
setting, save and exit.
11.7 The displayed temperature should have changed due to the calibration. Waiting for
another one hour to let the temperature stabilize again at 8°C, and check the thermometer value again, and calculate the new difference.
11.8 if necessary, perform the calibration again until the actual display value equals to the
calibrated thermometer value. Thus the Step 1. "Low Temperature Point Correction
(0.0)" is completed.
High Temperature Point Correction (100.0)
11.9 If the incubator is to be used for more than one temperature setting, and "High
Temperature Point Correction (100.0)" needs to be performed as well.
11.10
Change the set point to a higher temperature point as required, for example
60.0°C and let the incubator run for at least 1 hour– until the temperature is constant,
and let the temperature inside of the chamber is uniformed
11.11
Change the enter the code "47" again and press "SET" skip the "0.0", and enter
the "100.0" page.
11.12
Repeat the same procedure, like the "Low Temperature Point Correction", to
correct the high temperature point, until the display value equals to the actual
