Section 2 Calibrate

Once the freezer has stabilized, the control probe may need to becalibrated. Calibration frequency is dependent on use, ambient conditionsand accuracy required. A good laboratory practice would require at least anannual calibration check. On new installations, all parameters should bechecked after the stabilization period.

Before making any calibration or adjustments to the unit, it is imperativethat all reference instruments be properly calibrated.

Plug a type T thermocouple reader into the receptacle located inside thelower door (see Figures 1-4 and 1-6). Compare the control temperatureset point to the temperature of the measuring device.

1. Press the Mode key until the Calibrate indicator lights.

2. Press up/down arrow to match the display to calibrated instrument.

3. Press Enter to store calibration.

4. Press the Mode key to return to Run mode.

Startup - Allow 12 hours for the temperature in the cabinet to stabilizebefore proceeding.

Already Operating - Allow at least 2 hours after the display reaches setpoint for temperature to stabilize before proceeding.

Note During calibration, the temperature display will not be available. s

If no keys are pressed for approximately 5 minutes while in calibrationmode, the system will reset to Run mode.

Section 3 Alarms

The 700 Series ULT freezer alarms are displayed on the freezer controlpanel. When an alarm is active, the indicator next to the alarm descriptionwill light and there will be an audible alarm. Press the Silence key todisable the audible alarm for the ringback period. The visual alarm willcontinue until the freezer returns to a normal condition. The alarms aremomentary alarms only. When an alarm condition occurs and then returnsto normal, the freezer automatically clears the alarm condition.

The Wrong Power alarm occurs when incorrect voltage is applied to thefreezer. If a 230V freezer is connected to a 120V power source or a 120Vfreezer is connected to a 230V power source, the electronics will detect thatthe "Wrong Power" has been applied. Under this condition, the fans andcompressors will not turn on and an audible and visual alarm will occur.This alarm may also occur if the battery switch is turned to Standby mode( ) prior to applying power to the freezer. The audible and visual alarmswill remain until the freezer is connected to the correct power source. Theaudible alarm cannot be silenced under this condition.

Section 3Alarms

The "high stage system failure" condition is created when the high stagecompressor and fans run for 30 minutes and are not capable of cooling theinterstage heat exchanger to the proper temperature. Under this condition,the high stage compressor and fans will turn off after 30 minutes and anaudible and visual alarm will occur. The audible alarm can be silenced andwill ring back every 15 minutes.

The microprocessor in Model 700 Series freezers continually scans allprobes including the control probe, heat exchanger probe and condenserprobe to ensure that they are operating properly. Should an error bedetected, the "Probe Failure" alarm will occur as described in 3.1 above. Ifan error is detected with the control probe, the high and low stagecompressors will run continuously. As a result, the cabinet temperaturewill decrease until it reaches the lowest temperature that the refrigerationsystem can maintain. If an error is detected with the heat exchangerprobe, the freezer will cycle properly at its temperature set point using a 5minute step start between the high and low stage compressors. If an erroris detected with the condenser probe, there is no impact on theperformance of the freezer; however, the hot condenser alarm may alsooccur. Contact the Technical Services department (1-888-213-1790) oryour local distributor.

If the freezer is compensating for high or low line voltage, the system willmeasure the compensated AC voltage. If the voltage is incorrect, the unitwill stop attempting to compensate, and the compressor will run on directline voltage. Under this condition, there will be a visual and audible alarmthat can be silenced with a ringback period of fifteen minutes. This alarmcondition is unlikely to occur, and as such, there is no LED alarmindicator for this condition.

An internal communications failure has occurred with the micro board.Under this condition, a visual and audible alarm occurs that can besilenced with a ringback period of 15 minutes. The temperature displaysreads “E07”, and the remote alarm contacts trip. During this alarm, thecompressor(s) attempt to run continuously. With this type of failure,freezer operation becomes undependable.

Communication between the micro board and the display board has beenlost. Under this condition, the visual alarm flashes along with dashes in thetemperature display (----). Contact Technical Services.

PREVENTIVE MAINTENANCEFreezers

Your equipment has been thoroughly tested and calibrated before shipment. Regular preventive maintenance is important to keep yourunit functioning properly. The operator should perform routine cleaning and maintenance on a regular basis. For maximumperformance and efficiency, it is recommended that the unit be checked and calibrated periodically by a qualified service technician.

The following is a condensed list of preventive maintenance requirements. See the specified section of the instruction manual forfurther details.

We have qualified service technicians, using NIST traceable instruments, available in many areas. For more information on PreventiveMaintenance or Extended Warranties, please contact the Technical Services Department at 1-800-438-4851.

Cleaning and calibration adjustment intervals are dependent upon use, environmental conditions and accuracy required.

Tips:

• Fill an upright by starting at the bottom near the probe and add racks to one shelf at a time. Allow freezer to recover to set pointbetween shelves.

• Fill a chest by starting at the left side near the probe. Filling with room temperature racks will result in a long pull-down time.

• Fill unit with frozen product to help overall performance; frozen water jugs, for example.

• Always make certain the vacuum relief port is free of frost and ice, to allow for timely re-entry into the freezer after a door opening.

Action Monthly Yearly Every 2 Years

Verify ambient temperature, <90°F 4

* Adjust door handle for firm latching, as needed 4

Check and clean probe cover, gaskets, hinges and lid(s) of ice and snow. SeeFigure 1-4 for probe location. See “Clean Lid Gasket”.

Section 5 Factory Installed Options

Note Before installation of BUS components, make sure the power to thefreezer is disconnected, the battery switch is turned off (O) and the freezerhas warmed to ambient temperature. s

The built-in BUS (back up system) will keep the freezer chambertemperature below the critical level in the event of a power or equipmentfailure. If power to the freezer fails, or temperature increases to the back upalarm set point, the BUS injects liquefied gas into the chamber to keep thechamber temperature within the specified range.

The BUS operates on an internal 12-volt, rechargeable battery which iskept charged during normal operation by the integral battery charger.

1. Locate the mounting hole for installing the injection tee assembly. SeeFigure 5-1.

Note Cover the open end of injection assembly with tape to keepinsulation from entering the nipple. s

2. Slide 3/8” flatwasher over open end of nipple.

3. Insert the covered end of the injection assembly through the exteriorhole.

1 Installation category (overvoltage category) defines the level of transient overvoltage which the instrument isdesigned to withstand safely. It depends on the nature of the electricity supply and its overvoltage protectionmeans. For example, in CAT II which is the category used for instruments in installations supplied from a supplycomparable to public mains such as hospital and research laboratories and most industrial laboratories, theexpected transient overvoltage is 2500V for a 230V supply and 1500V for a 120V supply.

2 Pollution degree describes the amount of conductive pollution present in the operating environment.Pollution degree 2 assumes that normally only non-conductive pollution such as dust occurs with the exception ofoccasional conductivity caused by condensation.

Appendix A Handling Liquid Nitrogen

Warning Contact of liquid nitrogen or cold gas with the skin or eyes maycause serious freezing (frostbite) injury. s

Handle liquid nitrogen carefully.

The extremely low temperature can freeze human flesh very rapidly. Whenspilled on a surface the liquid tends to cover it completely and intimately,cooling a large area. The gas issuing from the liquid is also extremely cold.Delicate tissue, such as that of the eyes, can be damaged by an exposure tothe cold gas which would be too brief to affect the skin of the hands orface.

Never allow any unprotected part of your body to touch objects cooledby liquid nitrogen.

Such objects may stick fast to the skin and tear the flesh when you attemptto free yourself. Use tongs to withdraw objects immersed in the liquid,and handle the object carefully.

Wear protective clothing.

Protect your eyes with a face shield or safety goggles (safety glasses withoutside shields do not give adequate protection). Always wear gloves whenhandling anything that is, or may have been, in immediate contact withliquid nitrogen. Insulated gloves are recommended, but heavy leathergloves may also be used. The gloves should fit loosely, so that they can bethrown off quickly if liquid should splash into them. When handlingliquid in open containers, it is advisable to wear high-top shoes. Trousers(which should be cuffless if possible) should be worn outside the shoes.

Appendix AHandling Liquid Nitrogen

A -2 ULT Chest Freezer


A -2 ULT Chest Freezer

The safe handling and use of liquid nitrogen in cryogenic refrigerators anddewar flasks is largely a matter of knowing the potential hazards and usingcommon-sense procedures based on that knowledge. There are twoimportant properties of liquid nitrogen that present potential hazards:

1. It is extremely cold. At atmospheric pressure, liquid nitrogen boils at -320°F (-196°C).

2. Very small amounts of liquid vaporize into large amounts of gas. Oneliter of liquid nitrogen becomes 24.6 cu. ft. (700l) of gas.

The safety precautions in this booklet must be followed to avoid potentialinjury or damage which could result from these two characteristics. Do notattempt to handle liquid nitrogen until you read and fully understand thepotential hazards, their consequences, and the related safety precautions.Keep this booklet handy for ready reference and review.

Note Because argon is an inert gas whose physical properties are very similarto those of nitrogen, the precautions and safe practices for the handling anduse of liquid argon are the same as those for liquid nitrogen. s

Use only containers designed for low temperature liquids.

Cryogenic containers are specifically designed and made of materials that canwithstand the rapid changes and extreme temperature differencesencountered in working with liquid nitrogen. Even these special containersshould be filled SLOWLY to minimize the internal stresses that occur whenany material is cooled. Excessive internal stresses can damage the container.

Do not cover or plug the entrance opening of any liquid nitrogenrefrigerator or dewar. Do not use any stopper or other device that wouldinterfere with venting of gas.

These cryogenic liquid containers are generally designed to operate with littleor no internal pressure. Inadequate venting can result in excessive gaspressure which could damage or burst the container. Use only the loose-fitting necktube core supplied or one of the approved accessories for closingthe necktube. Check the unit periodically to be sure that venting is notrestricted by accumulated ice or frost.

Introduction

Use proper transfer equipment.

Use a phase separator or special filling funnel to prevent splashing andspilling when transferring liquid nitrogen into or from a dewar orrefrigerator. The top of the funnel should be partly covered to reducesplashing. Use only small, easily-handled dewars for pouring liquid. Forthe larger, heavier containers, use a cryogenic liquid withdrawal device totransfer liquid from one container to another. Be sure to followinstructions supplied with the withdrawal device. When liquid cylindersor other large storage containers are used for filling, follow the instructionssupplied with those units and their accessories.

Do not overfill containers.

Filling above the bottom of the necktube (or specified maximum level) canresult in overflow and spillage of liquid when the necktube core or cover isplaced in the opening.

Never use hollow rods or tubes as dipsticks.

When a warm tube is inserted into liquid nitrogen, liquid will spout fromthe top of the tube due to gasification and rapid expansion of liquid insidethe tube.

Warning Nitrogen Gas Can Cause Suffocation Without Warning! s

Store and use liquid nitrogen only in a well-ventilated place.

As the liquid evaporates, the resulting gas tends to displace the normal airfrom the area. In closed areas, excessive amounts of nitrogen gas reducethe concentration of oxygen and can result in asphyxiation. Becausenitrogen gas is colorless, odorless and tasteless, it cannot be detected by thehuman senses and will be breathed as if it were air. Breathing anatmosphere that contains less than 18% oxygen can cause dizziness andquickly result in unconsciousness and death.

Note The cloudy vapor that appears when liquid nitrogen is exposed to theair is condensed moisture; not the gas itself. The issuing gas is invisible. s

Never dispose of liquid nitrogen in confined areas or places where othersmay enter.

Disposal of liquid nitrogen should be done outdoors in a safe place. Pourthe liquid slowly on gravel or bare earth where it can evaporate withoutcausing damage. Do not pour the liquid on pavement.

Appendix B Handling Liquid CO2

Warning High concentrations of CO2 gas can cause asphyxiation! OSHAStandards specify that employee exposure to carbon dioxide in any eight-hour shift of a 40-hour work week shall not exceed the eight-hour timeweighted average of 5000 PPM (0.5% CO2). The short term exposurelimit for 15 minutes or less is 30,000 PPM (3% CO2). Carbon dioxidemonitors are recommended for confined areas where concentrations ofcarbon dioxide gas can accumulate. s

Store and use liquid CO2 only in a well-ventilated place.

As the liquid evaporates, the resulting gas tends to displace the normal airfrom the area. In closed areas, excessive amounts of CO2 gas reduce theconcentration of oxygen and can result in asphyxiation. Because CO2 gasis colorless, odorless and tasteless, it cannot be detected by the humansenses and will be breathed as if it were air. Breathing an atmosphere thatcontains less than 18% oxygen can cause dizziness and quickly result inunconsciousness and death.

Note The cloudy vapor that appears when liquid CO2 is exposed to the airis condensed moisture; not the gas itself. The issuing gas is invisible. s

Never dispose of liquid CO2 in confined areas or places where othersmay enter.

Disposal of liquid CO2 should be done outdoors in a safe place. Pour theliquid slowly on gravel or bare earth where it can evaporate withoutcausing damage. Do not pour the liquid on pavement.

Appendix C First Aid

If a person seems to become dizzy or loses consciousness while workingwith liquid nitrogen or carbon dioxide, move to a well-ventilated areaimmediately. If breathing has stopped, apply artificial respiration. Ifbreathing is difficult, give oxygen. Call a physician. Keep warm and atrest.

If exposed to liquid or cold gas, restore tissue to normal body temperature(98.6° F) as rapidly as possible, followed by protection of the injured tissuefrom further damage and infection. Remove or loosen clothing that mayconstrict blood circulation to the frozen area. Call a physician. Rapidwarming of the affected part is best achieved by using water at 108° F.Under no circumstance should the water be over 112° F, nor should thefrozen part be rubbed either before or after rewarming. The patient shouldneither smoke nor drink alcohol.
