Voltage-free contact
This part of the manual covers the voltage-free contact.
The illustration below shows the three connectors for the relay (used ex. in connecting to CTS or other external monitoring systems). The three connections, are respectively. Common, NO and NC.
The moment when voltage is applied the controller draws the relay, this makes it possible for the controller to respond to both high and low temperature alarms, door alarms and power failures. Temperature alarms and door alarms must be confi gured in the external alarm settings
(EAL) before they will activate the voltage-free contact. Find instructions on setting external alarms in the Parameter settings section.
The wires that are connected in the connection block for the voltage-free contact, are secured in place by the press-fi t plate that is pressed onto the block, thereby also preventing access to the electrical circuit.
Connection of the voltage-free contact should be done by a qualifi ed installer.

Mechanical low temperature protection
This part covers mechanical low temperature protection
The illustrations below depicts the locations of the low temperature protection on the different kinds of cabinets in the BioBlood range.
Applicable to BioBlood 425
- Only applicable to models with mechanical low temperature protection -
Mechanical low temperature protection is an independent module that is connected to the compressor.
It measures the cabinets temperature and turns off the compressor
(cut-off) if the temperature in the cabinet drops below the set value, ensuring that the cabinet does not become colder.
Please note that low temperature protection is set to between +2 and +2.5ºC as factory settings.
Ensure that the scale is set at the correct temperature prior to installation.
The scale of the low temperature protection is turned counterclockwise to adjust the “cut-off” down, and clockwise to adjust the “cut-off” up.
8
Example:
The compressor is turned off by the low temperature protection at
2.5 ºC, the desired “cut-off” temperature is 1.5 ºC.
Turn the scale on the low temperature protection counterclockwise until the desired value is set.
Applicable to BioBlood
500, 600/660 and
1270/1400

60079-15: Electrical apparatus for explosive gas atmospheres -
Part 15: Type of protection “n”. Zone 2 is the applicable zone. If the appliance is to be installed in a zone 2 environment, specialist personnel should perform the installation, or be consulted beforehand, in order to ensure that the appliance is installed in compliance with the guidelines currently contained in the standard.
The cabinet is intended for connection to alternating current. The connection values for voltage (V) and frequency (Hz) are given on the nameplate in the engine room.
The power cord from the mains is plugged in the terminal box, in the engine room. The plug is then fi xated in place by the hanger that is built into the terminal box. Please note that the hanger should be fi tted tightly around the plug, as shown below.
IMPORTANT
!
Fuses and similar must never be removed or replaced while the appliance is connected to a power source.
The electrical terminal box must never be opened while the appliance is connected to a power source.
The compressor starting equipment must never be dismantled while the appliance is connected to a power source.
The halogen lighting must never be dismantled while the appliance is connected to a power source.
Whenever electrical components are dismantled or replaced, the appliance must be moved to an area in which there is no risk of ignition caused by the electrical components or gases contained in the appliance.
Never use the cabinet if the plug is damaged. The cabinet should be examined by a Gram Commercial service technician in such cases.
The appliance must be connected to the external power supply using a suitable device which mechanically prevents the plug and socket from being separated unintentionally. The connection must be labelled:
”DO NOT SEPARATE WHEN ENERGIZED”
When setting up in an ordinary scenario that is not subject to regulations for Zone 2:
The appliance may be connected in accordance with applicable local heavy current regulations.
In both cases:
Use a three-wire plug, if the power outlet is intended for a three-wire plug, a the lead in green / yellow insulation should be connected to the ground terminal.
Power must be connected via a wall socket. The wall socket should be easily accessible.
All earthing requirements stipulated by the local electricity authorities must be observed. The cabinet plug and wall socket should then give correct earthing. If in doubt, contact your local supplier or authorized electrician.

Sensor calibration
The following part covers the calibration of the
A- and E-sensor.
The temperature sensors connected to MPC controller can be calibrated independently of each other under the parameter cAL.
Calibration is used in cases where there are deviations in the cabinets actual operation compared to the display and / or control measurements by independent temperature monitoring.
The cabinet is equipped with a sensor (A-sensor) and an extra sensor (E-sensor).
The A-sensor is used to manage the cabinets refrigeration system and is fi xated in a given position in the cabinet, not in storage space.
The location of the A sensor must not be altered.
The E-sensor is placed in the cabinet storage space and can be moved around in the cabinet to get the desired reference point for temperature. The E-sensor is the default display sensor and reference for the alarms. The E-sensor has no effect on control of the refrigeration system.
Calibration of the A-sensor
Press and hold + for more than 3 seconds
Press to calibrate the A-sensor
-The A-sensor is now calibrated, proceed to other parameters by pressing , and then navigate by using or
Leave the user menu by pressing several times until the cabinet temperature is shown in the display
The A-sensor is calibrated if the actual temperature in the cabinet does not match the setpoint, despite taking the hysteresis into consideration. Calibration of A sensor is named “cA”.
The E-sensor is calibrated if the actual temperature in the cabinets display, provided that the display sensor for reference is the
E-sensor, does not match the independent temperature monitoring used for control. Calibration of E-sensor is named “cE”
Calibration of the E-sensor
Press and hold + for more than 3 seconds
Press to calibrate the E-sensor
Practical example of calibration:
Example 1 - The temperature in the cabinet is operating colder than the actual setpoint.
With a setpoint of +4 °C, the actual temperature inside the cabinet is between +2 and +4 °C. The desired temperature range is between +3 and +5 °C. This means that “cA”, in this case, should be
-1,0K, so that the refrigeration system stops 1,0K before and starts
1,0K later than the setpoint normally otherwise would dictate.
- The E-sensor is now calibrated, proceed to other parameters by pressing , and then navigate by using or
Leave the user menu by pressing several times until the cabinet temperature is shown in the display
Example 2 - The temperature in the cabinet is operating warmer than the actual setpoint.
With a setpoint of +4 °C, the actual temperature inside the cabinet is between +4 and +6 °C. The desired temperature range is between +3 and +5 °C. This means that “cA”, in this case, should be 1,0K, so that the refrigeration system stops 1,0K later and starts
1,0K earlier than the setpoint normally otherwise would dictate.

Keep the marked areas in the cabinet (shown on this page) clear of all items, thereby ensuring adequate air circulation, and therein cooling.
Do not place items beneath the lowest shelf bracket.
All products to be stored, that are not wrapped or packed, must be covered in order to avoid unnecessary corrosion of the inner parts of the cabinet.
!
Items placed on the bottom of the cabinet will cause the air circulation to be impeded, which reduces the cabinets performance.
The items should be evenly distributed in the cabinet, with minimum layer-thickness / maximum surface. And at the same time, the air should be able to circulate freely between the items.
The illustration on the right shows the maximum load height of the cabinet.

Regular maintenance
b i o l i n e
Cleaning
Inadequate cleaning can lead to a the cabinet not functioning properly or at all.
Door gasket
The following part covers the importance of a properly functioning door gasket.
Always disconnect the cabinet before cleaning.
The cabinet should be cleaned internally with a mild soap solution
(max. 85 °C) at suitable intervals and checked thoroughly before it is put into operation again.
For the external maintenance – use stainless steel polish.
The compressor compartment and in particular the condenser must be kept free from dust and dirt. This is best done with a vacuum cleaner and a brush.
The air fi lters on the condenser and the front panel should be removed and cleaned with warm water (max. 50°C).
The re-evaporation tray should be emptied and cleaned at least once a year.
Do not fl ush compressor compartment and evaporator with water as this may cause short-circuits in the electrical system.
Cleansing agents containing chlorine or compounds of chlorine as well as other corrosive agents, may not be used, as they might cause corrosion to the stainless panels of the cabinet and the evaporator system.
Door gaskets are an important part of a cabinet, door gaskets with impaired functionality reduces a cabinets seal with the door.
Impaired seals can lead to increased humidity, iced evaporator
(and thus reduced cooling capacity), and in some cases, decreased lifetime expectancy of the cabinet.
It is therefore very important to be aware of the door gaskets condition. Regular inspection is recommended.
The door gasket should be cleaned regularly with a mild soap solution.
If a gasket is to be replaced, please contact your local Gram BioLine distributor.
The illustration below shows the location of the seal on a BioBlood
660
The location of the condensers for both bottom- and top-mounted cabinets is illustrated below.

The cabinet has to be disconnected at the mains if service is to be done on electrical components of the cabinet.
It is not suffi cient to switch the cabinet off on the front panel, due to the fact that there is still a possibility that there is current in some of the components of the cabinet.
Contact Gram customer service or qualifi ed personnel if the bulb(s) in the two spots above the door needs replacing

b i o l i n e
Defrost water
The cabinet creates defrost water , that is directed out into a re-evaporation tray at the back of the cabinet.
Door closing mechanism
Please note that BioBlood cabinets are equipped with doors that have a self-closing mechanism.
BioBlood (500, 600/660, 1270/1400):
Defrost water is led through a tube in insulation to a re-evaporation tray at the back of the cabinet.
The door is equipped with an automatic closing mechanism. Open the door up to 90 °, and it will shut by itself. Open the door more than 90 ° and door will remain open.
BioBlood 425:
Defrost water is led through a tube in the insulation to a reevaporation tray in the compressor room in the cabinet.
!
It is recommended that the re-evaporation tray is cleaned at least once a year. This shall only be done while the cabinet is turned off.
Be careful not to damage the defrost water tube and heating element (located in the tray) when cleaning.
Below are the re-evaporation trays for a BioBlood 425 and BioBlood
600 shown

Access port
All BioLine cabinets are equipped with an access port on the back of the cabinets, this can be used to easily fi t external sensors and the like.
The illustration below shows an access port on a BioBlood 600 cabinet.
All access ports are constructed in the same fashion, with a conical polystyrene plug ( fi tted from the back of the cabinet ) and a plastic cap ( fi tted from the inside of the cabinet ).
Please note, it is very important to re-fi t the polystyrene plug and plastic cap after mounting sensor, probe etc. Failing to do so can result in lowered performance or break-down of the cabinet.

Guideline for Service Technicians
- How to handle blood infected equipment when servicing BioBlood cabinets -
This guideline is intended to provide guidance for employees servicing BioBlood cabinets. Thereby ensuring that contact with biohazardous specimens (e.g. blood), does not lead to contamination and thereby infection.
Foreword
Gram BioBlood cabinets are intended for storage of blood and/or specimens that could be hazardous to your health if infection occurs.
With this in mind, simple but effective precautions can be taken to enable you to work safely with/around BioBlood cabinets.
1 - Ensuring maximum facility and patient safety -
There is always an inherent risk of you, contributing to contamination of the facility, its equipment and potentially, its patients when servicing a BioBlood cabinet. Therefore:
• Ensure that your tools are adequately clean prior to any work on a BioBlood cabinet.
• Ensure that you are not ill, when servicing a BioBlood cabinet!
This includes anything from the common cold, infl uenza and diarrhoea to pneumonia and anything in between. You as a host of an illness, have the risk of contaminating the facility, its equipment and potentially infecting patients if you disregard this precaution.
If you are sick, or have a suspicion of coming down something, do not hesitate to sign off the job to another colleague. We encourage full disclosure on this part, patient safety is of upmost importance.
The main focal point is that we want to ensure lowest possible risk of contamination!
2 - Always follow local hygiene regulations-
• Always follow any local hygiene regulations that may apply to the facility in which you are servicing a BioBlood cabinet.
3 - Recommended personal behaviour by our bioanalyst -
• All equipment used for biohazardous specimens (blood, plasma or other material of human origin) are to be considered infected.
• Leave coat, and other personal belongings not needed for the job, in a safe area (gowning room, wardrobe etc).
• Always use rubber gloves, the facility in which you are servicing the BioBlood cabinet can supply gloves if you do not have your own.
• Be exceedingly careful If you have wounds/scratches, as these wounds/scratches renders you without protection from biohazards if contact should occur.
• Always consider gloves as contaminated, even if it is not visually apparent. It is important that you consciously only touch what you consider contaminated areas i.e the inside of the cabinet of the BioBlood cabinet - if you need “clean hands”, remove the gloves and wash your hands before touching personal belongings such as phones, car keys etc.
• Change gloves immediately if they are visually contaminated.
• Consider your toolbag, tools, notepad, pens etc. used when servicing the cabinet as contaminated, this means that these items are not to be used outside facilities using BioBlood cabinets. This applies especially to your own home or with customers that are not in the hospital sector.
• Phone, laptop, car keys and the like, should never come in direct contact with tools and equipment that have been used in contaminated areas. If you need to use the phone, laptop or similar while servicing a cabinet, wash your hands thoroughly in advance.
4 - Wash hands -
• After contact with any BioBlood cabinet you should wash your hands and wrists very carefully with soap and disinfectant (also applies when gloves have been used, as they do not restrain all kinds of biohazardous specimens).
5 - Change your clothes -
• If you have been working with a BioBlood cabinet, you should always change your clothes immediately after leaving the facility.
This applies regardlessly of you going directly home, to the offi ce or another service job.
