    4.2. Power Connection

    Warning! Before making the power supply connection to your unit, you must perform the following procedure:

    1. Verify the power supply voltage rating established for your chamber (listed above). The

    voltage rating is also found on the serial tag on the side of the oven. Note the rated value here:

    2. Measure and record the intended voltage source.

    Note the measured value here:

    3. Reference the Line Voltage Min/Max Tables below. Verify that the power supply voltage source you measured and recorded is within the minimum and maximum allowable operating voltages for your chamber rating. If it is not within this operating range, do not make the power connection! Otherwise, erratic operation and damage may occur to your equipment, which may void your warranty. If you have any questions, please call the NEWTRONIC Service Department.

    Important! One of the most common causes of equipment malfunction is low line voltage as the power source to the unit. Ordinarily in this condition, the heat output would be reduced and the system's motors would operate erratically, eventually overheat, and shut down. You must be certain that your equipment is connected to a circuit with an adequate voltage and current source. An oversupply voltage would also cause erratic operation and eventual shutdown, or damage to your equipment.

    Supply Voltage should remain 23010Volts at all-time having 50Hz frequency Operation outside this limits can results in damage to controller.

  • User Manual 2.0

    BOD Incubator Page 8 of 32

    Making the Power Supply Connection to the Chamber: A main power disconnect switch is normally provided with your small chamber. We recommend that a fused disconnect switch on a separate branch circuit be installed as the power source to your chamber, in accordance with all national and local electrical codes. Reference your Electrical or Power Schematic for all electrical requirements. The power connection is made via a cord and plug for standard units. Connect the plug to a receptacle that has the appropriate power supply on a branch circuit of its own.

    Warning! High Accessible Current An Earth connection is essential before connecting the power supply. Make sure equipment is properly grounded in accordance with all codes.

    Application of Power Before energizing any equipment, make a visual inspection for loose components,

    electrical connections, fittings, etc. Shut all operating switches to the OFF position before energizing.

    Have trained personnel start and check out the equipment before its first cycle.

    5. Product Description System Overview: NEWTRONICs BOD Incubators are engineered with precise control action. Heaters are mounted on the right side of chamber. Air circulation system provides maximum uniformity. The air circulation system sucks air from chamber; allows it to pass trough heater and back in the chamber. Accurate Temperature PID controller ensures tight control without over shoots of temperatures. Over temperature safety device provides protection against overshoots of temperature.

    5.1. Heating System

    Heating is done by long lasting stainless steel tubular heaters. Heating system controls temperature in the BOD Incubator using PID function. Supply to heaters is controlled by solid state relay. Safety relay prevents excessive temperatures and possible damage to samples or equipment.

  • User Manual 2.0

    BOD Incubator Page 10 of 32

    5.2. Air Circulation

    Air circulation system is provided for maximum uniformity of temperature. The circulation motor is mounted on the back side of equipment. It remains continuously ON for uniformity of temperature. Process air is conditioned as it is drawn through the chamber by fan/blower wheel. It is than passed through heaters and the refrigeration coil. The conditioned air is discharged down and then enters the workspace through semi-pierced openings over the entire width of plenum of the working chamber. Air flows horizontally across the working space and then gets distributed on both side of the chamber. It is then passes through product vertically/horizontally and exits the workspace through circular semi-pierced openings at the top of plenum. Processed air flows from bottom and returns to the plenum for reconditioning. A inbuilt Temperature sensor is used to measurement of temperature inside the chamber. The control sensor is placed in the discharge air in the right side duct wall for better accuracy and control. Adjustable ventilation is provided for air changes in the Incubator.

    5.3. Cooling System

    CFC free (Refrigerant 134A) cooling system consists of hermitically sealed compressor coupled with evaporation coil and condenser provides required cooling. Compressor is been safe guarded by time delay programmed in the controller and by using a robust electromagnetic relay circuit. The condenser unit is mounted in the top compartment of the chamber. Temperature will raise minimum 5C above ambient in case of Cooling System OFF/ not working Low temperature safety thermostat prevents excessive cooling.

    It is recommended to keep Cooling ON for set temperature of 10C to 35C. For

    temperature above 35C cooling should be kept OFF. Note: 1. The ambient/ environment room condition where chamber is going to be

    placed/kept must be between 25C to 30

    10. Maintenance Only qualified service personnel should ever be permitted to perform any service related procedure on this chamber! Disconnect and Lock-Out / Tag-Out all electrical power from the facility at its source before servicing or cleaning.

    Frequency of preventive maintenance procedures depends upon how the facility is used and upon other circumstances. Because of this, a hard and fast schedule of maintenance operations is difficult to present. Indeed, an inflexible schedule might be suitable for one user, but completely inadequate for another. Therefore, we have provided periodic figures when to perform maintenance procedures, based on the average chamber use. We suggest that you maintain a preventive maintenance log. In this log you will record operating notes, pressures, temperatures, and electric readings. The log is valuable because it will help maintenance and service people by documenting long term trends and by showing parameter levels when the chamber is operating properly.

    10.1. Interior/Exterior surfaces

    The interior and exterior surfaces of the chamber are best cleaned by using warm water with mild soap and a clean soft cloth. For finger prints or other stains, mild, non-abrasive cleaners may be used. On stainless steel outer body with a satin finish, run strokes in the direction as the grain. Inspection Period: 15Days

    10.2. Door Gasket

    Door gaskets should be cleaned on a regular basis. To clean the gasket, use baking soda and warm water, wiping dry with a soft cloth. The vinyl gasket from around the inside door will assure an air tight seal if properly maintained and inspected regularly. When inspecting, check that the gaskets are properly seated in their retainers. A visual check for wear and tear is also required. If gaskets should become torn or broken, they should be replaced immediately. Inspection Period: 30Days

    10.3. General Electrical Connections

    Warning! Remove All Power From Chamber!

    Inspect inside the control panel and the machinery compartment for loose electrical connections, frayed wires, loose components, or other potential problems. Inspection Period: 6 Months
