Tighten retaining screws to secure. Figure 1-9. Power Cord Connection Connect Unit to Electrical See the serial tag on the side of the unit for electrical specifications or refer to the electrical schematics in this manual.
Section 1 Installation and Start-Up Freezer Start-Up With the freezer properly installed and connected to power, system set points can be entered. The following set points can be entered in Settings mode: Control temperature, high temperature alarm set point, low temperature alarm set point, and (optional) BUS set point.
Section 1 Installation and Start-Up Set High Temperature The high temperature alarm will activate an audible/visual warning when the freezer chamber temperature has reached or exceeded the high Alarm temperature alarm set point. To set the high temperature alarm set point: 1.
Section 1 Installation and Start-Up Run Mode Run mode is the default mode for the freezer. This mode displays the cabinet temperature on the temperature display under normal operating conditions. In addition, the Run mode allows display of the high stage heat exchange temperature.
Calibrate Section 2 Once the freezer has stabilized, the control probe may need to be calibrated. Calibration frequency is dependent on use, ambient conditions and accuracy required. A good laboratory practice would require at least an annual calibration check. On new installations, all parameters should be checked after the stabilization period.
Alarms Section 3 The Model 900 Series freezer alarms are displayed on the freezer control panel. When an alarm is active, the indicator next to the alarm description will light and there will be an audible alarm. Press the Silence key to disable the audible alarm for the ringback period.
Section 3 Section 3 Alarms Alarms High Stage System The "high stage system failure" condition is created when the high stage compressor and fans run for 30 minutes and are not capable of cooling the Failure interstage heat exchanger to the proper temperature. Under this condition, the high stage compressor and fans will turn off after 30 minutes and an audible and visual alarm will occur.
Maintenance Section 4 Clean Cabinet Exterior Wipe down the freezer exterior using soap and water and a general use laboratory disinfectant. Rinse thoroughly with clean water and dry with a soft cloth. Caution Avoid the excessive use of water around the control area due to the risk of electrical shock.
Section 4 Section 4 Maintenance Maintenance Clean Water-cooled The water-cooled condenser can be cleaned-in-place by using the CIP procedure. Cleaning solutions can be used, depending on type of deposits Condenser or build-up to be removed. Note Do not use liquids that are corrosive to stainless steel or the brazing material (copper or nickel).
Section 4 Section 4 Maintenance Maintenance Defrost Chamber 1. Remove all product and place it in another freezer. 2. Turn the unit off and disconnect it from the power source. 3. Turn off the battery switch (O). See Figure 4-6. 4.

Section 4 Section 4 Section 4 Section 4 Maintenance Maintenance Maintenance Maintenance Vacuum Relief Port The time required to draw 1.5-3.0 cu.ft. of air into the cabinet depends on two factors: (continued) a) the size and number of paths available for the air to enter the cabinet, and b) the pressure difference between the internal cabinet and the ambient room.

Section 4 Maintenance Vacuum Relief Port 3. The air exchange will be audible and could last a few Maintenance minutes. 4. As the air pressure equalizes, the door releases. Warning Do not leave the freezer unattended while the door is unlatched.
Section 4 Maintenance Replace Battery(s) 1. To gain access to the battery, open the lower door by grasping the bottom left corner. The battery is rectangular in shape, located on the front left corner of the compressor compartment and is secured in place by a mounting bracket.
Section 4 Maintenance PREVENTIVE MAINTENANCE Freezers Your equipment has been thoroughly tested and calibrated before shipment. Regular preventive maintenance is important to keep your unit functioning properly. The operator should perform routine cleaning and maintenance on a regular basis. For maximum performance and efficiency, it is recommended that the unit be checked and calibrated periodically by a qualified service technician.
Factory Installed Options Section 5 BUS - Back Up System Note Before installation of BUS components, make sure the power to the freezer is disconnected, the battery switch is turned off (O) and the freezer (195875, 195877) has warmed to ambient temperature. ▲...

Section 5 Factory Installed Options Install Vent Stack, Solenoid 7. Inside the chamber, seal around the end of the vent stack with Permagum. and Injection (continued) 8. Install the transfer hose connecting one end to the injection assembly, the other to the solenoid valve. Connect the solenoid valve to the supply source.
Section 5 Factory Installed Options BUS Control Panel The following section describes the configuration and operation of the BUS. Warning When activated, this unit injects liquid nitrogen or carbon dioxide. Liquid nitrogen can cause serious freezing (frostbite) if it comes in contact with unprotected skin or eyes.
Section 5 Factory Installed Options Configure Optional BUS The optional BUS can be configured for LN or CO supply. (Back Up System) To select the supply type: 1. Press the Mode key until the Backup indicator lights. 2. Press the up or down arrow key. The display will show OP1 for CO2 selection and OP2 for LN2 selection.
Section 5 Factory Installed Options Clean Vent Stack Routinely check the vent stack for frost or ice build-up. The type of frost that forms in the vent stack is generally very soft and may be easily removed with a bristle brush or soft cloth. If ice build-up has occurred, a complete defrost may occasionally be required.
Section 5 Factory Installed Options Change Recorder The chart recorder contains eight temperature ranges and is factory- programmed for the freezer. To change the recorder range: Temperature Range 1. Press and hold button #3 for one second, then let the pen move off the chart paper.
Section 5 Factory Installed Options Datalogger Dataloggers and ELPRO evaluation software provide monitoring and documentation of temperature and alarm conditions. The dataloggers have a memory capacity of 64,000 measured values or data points. Temperature is measured, stored and displayed. Alarm conditions are recorded. Evaluation software permits data to be downloaded to a PC.

Handling Liquid Nitrogen Appendix A Warning Contact of liquid nitrogen or cold gas with the skin or eyes may cause serious freezing (frostbite) injury. ▲ Handle liquid nitrogen carefully. The extremely low temperature can freeze human flesh very rapidly. When spilled on a surface the liquid tends to cover it completely and intimately, cooling a large area.

Appendix A Appendix A Handling Liquid Nitrogen Handling Liquid Nitrogen Introduction The safe handling and use of liquid nitrogen in cryogenic refrigerators and dewar flasks is largely a matter of knowing the potential hazards and using common-sense procedures based on that knowledge. There are two important properties of liquid nitrogen that present potential hazards: 1.
Page 80
Appendix A Handling Liquid Nitrogen Use proper transfer equipment. Use a phase separator or special filling funnel to prevent splashing and spilling when transferring liquid nitrogen into or from a dewar or refrigerator. The top of the funnel should be partly covered to reduce splashing.
Handling Liquid CO Appendix B Warning High concentrations of CO gas can cause asphyxiation! OSHA Standards specify that employee exposure to carbon dioxide in any eight- hour shift of a 40-hour work week shall not exceed the eight-hour time weighted average of 5000 PPM (0.5% CO ).
First Aid Appendix C If a person seems to become dizzy or loses consciousness while working with liquid nitrogen or carbon dioxide, move to a well-ventilated area immediately. If breathing has stopped, apply artificial respiration. If breathing is difficult, give oxygen. Call a physician. Keep warm and at rest.
