OPERATING INSTRUCTIONS FOR LABCOLD BS BLOOD BANK POSITION The cabinet should be stood on a firm level surface away from direct heat sources such as steam pipes, autoclaves or ovens. It is better to avoid direct sunlight if possible. POWER REQUIREMENTS The power cable with moulded on plug supplied with this cabinet is coded as follows : Brown Blue Green and Yellow

- Live - Neutral - Earth

It is rated for 220/240 volts 50Hz unless made to your special order for a different supply. It is essential that the cabinet is earthed. The supply must be fused at 13 amps unless otherwise indicated. BEFORE START UP If the cabinet has been tilted during its positioning it is important that it is left to stand for 12 hours before connecting the power. (This procedure allows compressor oil to return to the sump and prolongs compressor life expectancy). Some models have a separate vaporiser tray to get rid of waste water from the automatic defrosting system. This is fitted at the back on the bottom. DO NOT TOUCH this tray as it gets very hot. The recording thermometer will need the pen fitted. Access to the recorder is by key (there are two sets of keys supplied, one for the recorder and one for the door). Open the recorder door and lift the pen arm gently away from the chart, remove the pen tip cover. To fit a new chart, unscrew the outer knurled ring and remove from the shaft, lay the chart over the spindle and rotate so the pen arm will touch the right time and day. Then screw the ring on the spindle down to secure the chart and clip chart under the tab on the face of the recorder. Lower the pen arm to its set position above the chart and close the outer door. For full details of the recorder see separate operating instructions. OPERATION Connect power supply. The operating temperature and alarm thresholds are factory set and should require no adjustment. The cabinet will pull down to operating temperature which can be confirmed by the indicating and recording thermometer. This cabinet has been set up to the perametres shown on the enclosed certificate and should not require further adjustment. DOOR LOCK This model may be fitted with a magnetic lock controlled by a 12 character key pad. The code for the lock is “1111”, this is factory set. After the code is put in, you then have a one second delay before opening the door. After fifteen seconds the keypad resets and the door will lock when closed. If there is a power failure the door will be unlocked, it is therefore recommended that the key lock is used in the case of a prolonged power failure.

INNER DRAWERS DO NOT OPEN MORE THAN ONE DRAWER AT A TIME If your cabinet is fitted with drawers, they can be removed by extending the drawer fully on its runners and pressing the black levers (right hand side up and left hand side down). The drawer can now be removed. To replace the drawer just slide back into position. To adjust the drawer dividers backwards and forwards, grasp the two ends of the divider and walk the divider along the rods using a rocking motion. The dividers can be removed by undoing the screws holding on the face plate and removing the rods from the keyhole slots. DOORS PLEASE ENSURE THE INTERNAL DOORS OR DRAWERS ARE FULLY CLOSED BEFORE CLOSING THE OUTER DOOR. DO NOT SLAM THE DOORS OF A DOUBLE DOOR UNIT AS THE TRAPPED AIR PRESSURE OF THE CLOSING DOOR CAN OPEN THE OPPOSITE DOOR. DUAL SYSTEM CYCLING (WHERE FITTED) This unit is provided with two independent refrigeration systems to give complete product security. To maintain the system in good condition the work load is shared between the system, asymmetrically on a time basis. With the switch in the “Auto” position (autocycle) the two systems will cycle. You may notice that a different unit indicator on the front panel illuminated from time to time. If one of the systems fails note which system is active, the unit can then be switched to either 1 or 2 unit (opposite number to the unit that has failed) by positioning the switch on manual and pressing the button once to change to the other system. The switch and displays can be found on top of the control box behind the blue fascia. RL1

CARE AND MAINTENANCE The following routine cleaning and maintenance should be carried out in order to ensure that the refrigerator continues to function effectively when in use. THERMOGRAPH AND ALARMS The recording thermograph and alarm system should be tested at least once each week, preferably after changing the temperature chart. The records of such testing should be kept in a permanent log. The chart of the recording thermograph should be changed when completed, dated, labelled for proper identification of the refrigerator and signed by the person responsible for changing the charts. Note: These charts should be retained for at least 11 years. Important: The recorder battery should be changed every 6 months or if the unit fails to rotate or tick. DOOR SEALS The door seals should be visually checked for cleanliness, deterioration and air leakage at least once each week. OBSERVATIONS The following checks should be carried out daily: (a) For any unusual noise or apparent vibration; (b) For any evidence of build-up of condensed water on the internal surfaces of the refrigerator; (c) For any condensation of water on external surfaces; (d) That the air circulating fan operates; (e) It is recommended that the cabinet is checked for loose fixtures and fittings. CLEANING All internal surfaces should be cleaned periodically using a mild (neutral) detergent solution. The coils of the external heat exchanger should be cleaned at least once every 3 months to remove build-up of dust. Whenever blood is spilt on the internal or external surface of the refrigerator, the spill should be wiped immediately clean and the surface decontaminated using a suitable disinfectant. After decontamination, the surface should be rinsed clean. Where manual defrosting is necessary care should be taken not to use sharp instruments which may damage the lining.

BLOOD-BANK ALARM UNIT Description The blood bank alarm unit uses a micro-controller which is programmed to provide all the necessary functions. The unit is fitted to a blood-bank temperature-controlled cabinet to ensure that if the temperature does not stay within predetermined limits, alarms are generated to attract attention. The basic function of the unit is to sense the temperature in the cabinet by means of a thermistor probe, and to generate visual, audible and remote alarms if the temperature moves outside pre-set limits. In addition a door switch senses when the door is open and generates an alarm. The state of the cabinet is displayed, the messages being one or more of the following: NORMAL OPERATION DOOR OPEN LOW TEMPERATURE HIGH TEMPERATURE MAINS FAILURE CHECK BATTERY When the unit is switched on, or if the ‘TEST’ button is pressed, the unit first of all performs a self check during which the display shows the programme version number, followed by the above messages in sequence, and then the local sounder is activated briefly. After these tests are complete the unit starts monitoring for faults, and when there is a fault, the appropriate message is repeatedly flashed on the display, and, after a delay, the local and remote alarms operate. In the case of two or more faults being present at the same time e.g. ‘OPEN DOOR’ and ‘HIGH TEMPERATURE’, the error messages are repeatedly flashed on the display alternately, each for about one second. When the continuous message ‘NORMAL OPERATIONS’ is displayed a flashing hyphen between the words confirms that the alarm programme is running normally. The display is a green electro-luminescent, 16 character x 1 line module. Delays in Operation of Alarms To avoid nuisance operation there is a delay of ~3 minutes after a temperature or door fault is detected before the audible alarm is activated, however the alphanumeric display responds immediately. If an audible alarm is cancelled and a further fault occurs, the audible alarm will resound after ~3 minutes. In the case of ‘MAINS FAILURE’, the alphanumeric display and the audible and remote alarms are activated immediately. All of the alarm indications cease as soon as the fault condition returns to normal. The ‘CHECK BATTERY’ alarm is advisory and does not generate an audible or remote alarm. Remote Alarms To avoid nuisance alarms the closure of the contacts has an additional delay of 6 mins built in to allow the operator to accept the alarm before the switchboard is alerted. To test the remote connections,either an alarm must be triggered, by opening the door for instance and the alarm left unmuted for 6 minutes,or switch off the unit at the mains. The contacts will change state after a short delay Settings The alarm has the following fixed settings built in :Acceptance of an alarm from detection of an abnormal state - 3 mins. Acceptance of a door alarm - 3 mins Cancel time recall –15 mins Temperature settings low alarm 2oC. High alarm 8oC .

Mute Button This silences the audible and remote alarms for ~15 minutes but only operates if there is in fact a fault present, so that casual pressing of the button when all is healthy will not prevent correct response to a later fault condition. N.B. Following a failure of the mains, the MUTE button silences the sounder, which remains silent until the mains supply is restored. During a failure of the mains the remote alarm can not be cancelled. Test Button Pressing the TEST button will restart the unit, repeating the above tests and resetting timers and alarms. If any faults are still present, the appropriate message appears and the audible and remote alarms operate after the normal delay (~3 minutes), (except in the case of mains failure). Watchdog Timer The watchdog timer is a part of the processor which monitors programme operation, and if for any reason the programme should halt, the watchdog timer will restart the alarm unit thereby providing continuous protection. Brown-out Protection Circuit The brown-out circuit is included to protect against drops in mains supply voltage which might otherwise cause the alarm to malfunction. When the supply voltage falls below a critical level and then returns to normal, this circuit restarts the alarm unit. Standby Battery The nickel cadmium battery is trickle charged when the mains supply is present, its condition is monitored and if a fault is detected the ‘CHECK BATTERY’ message will be displayed. In the event of a mains failure the battery will maintain the operation of the unit for ~2.5 hours. If the mains supply fails, the sounder pulses (~2 per sec, ~0.1 sec duration) until it is cancelled, and it remains cancelled until the mains supply is restored. The alphanumeric display read ‘MAINS FAILURE’ until the mains supply is restored or the battery is discharged. The remote alarm activates and can not be cancelled manually but resets when the mains supply is restored. The remote alarm will remain activated even if the standby battery discharges and the alarm unit shuts down. Defrost Facility If the cabinet is supplied with a defrost cycle with normally open volt-free contacts to signal the cycle, these contacts can be connected between pins 7 and 8 of the 16 way orange connector on the alarm board. The alarm board will then ignore any faults occurring during the defrost cycle, however, should the cabinet stick in defrost mode the alarm board will return to monitoring faults after ~60 minutes. N.B. The MUTE button will not function during defrost which is not important as all alarms are suppressed, but should the cabinet be stuck in defrost cycle the temperature will rise, and ~60 minutes after the start of the defrost cycle the ‘TEMPERATURE HIGH’ alarm will sound. It will not be possible to cancel the alarm under these conditions, call an engineer. LABCOLD Unit F The Loddon Centre Wade Road Basingstoke RG24 8FL
