Section 3 Installation & Operation cont. 8) Shelves are pre-positioned to provide the best storage configuration. To remove each shelf For cleaning for example, slide them forward and lift. 9) Allow the refrigerator to operate until the temperature as displayed on the digital display reaches and stabilises at +4 C. Set up the chart recorder in next step. 10) Chart Recorder Set up (TCR-115) Thermograph Monitors and logs the internal temperature of the Blood Refrigerator. The dark band on the chart paper indicates the zone within which the blood temperature should remain. With the appropriate key, unlock the transparent cover on the Chart Recorder unit mounted centrally on the control panel. 11) Using a coin or similar, turn the centre spindle of the chart paper ANTI-CLOCKWISE ONLY to adjust to correct time and day. If the chart paper is turned clockwise, then a fault may arise, where the chart paper is actually 'ahead' of the timer motor. So, it may appear that the chart is not turning or it is slow when the timer motor maybe just 'catching up'. 12) Carefully remove the pen nib cover from the nib arm assembly. It is advisable to twist the cover while you are removing it. Press the lever at the opposite end of the arm to lower the nib onto the chart paper checking that the nib contacts the paper. 13) At the bottom left hand corner of the chart recorder face a pot labelled 'ADJ' is located. This pot is for calibration purposes and adjustment is not usually required at this point. Close the transparent cover of the recorder and lock accordingly to prevent tampering. 14) Internal Cabinet View Light - A viewing light is mounted at the top front internally of the cabinet which can be switched by a pushbutton switch beside the light assembly.

Section 3 Installation & Operation cont. 17) Performing the Alarm Test Sequence As a quick guide, please refer to the TS 1000 Alarm test Sequence in Section 4. Before commencing the Test, notify if applicable your security personnel that you are about to do so. They will receive a signal via the remote contacts on the refrigerator. Cabinet temperature will stabilise within 60 minutes of commencing the test sequence. It is suggested that you again contact security to verify that they did receive notice of an alarm. Important Notes regarding the TS-1000 and Test Sequence i) Frequency of Tests The test sequence can be performed quite regularly however usual frequency is once weekly. Always allow temperature to stabilise again before testing. ii) LOW BATTERY situation If this alarm occurs during the Test Sequence it will generally occur early in the sequence. If the Battery voltage drops below 11VDC, then the test will be aborted, the LOW BATTERY alarm will be activated with all signals emitted. The Battery will possibly need replacing. Refer to the Maintenance and Servicing section of the this manual for Battery location and servicing. iii) A Test Sequence will not initiate if the cabinet temperature is above the HIGH TEMP alarm setpoint or if there is a POWER LOSS situation. If the TEST button is pressed in these instances, then nothing will occur. DOOR AJAR ALARM This refrigerator is supplied with a door ajar alarm whereby an audible signal will sound when the cabinet door is opened for an extended time period. Alarm Sequence Door open time > 1 x minute = 1 x beep pulse/5seconds Door open time > 2 x minutes = continuous beep pulse Note To prevent nuisance alarming remote alarm is not activated whilst door ajar alarm occurs. If door is left open unattended, then it is expected that the HIGH TEMP alarm will be activated and notify security personnel. If you are loading the refrigerator with stock and have to keep the door open for longer than normal, to reset the alarm, simply close and reopen door. If the refrigerator is to be stored or shut down for a period exceeding 1 week then it is suggested that the Battery is disconnected by physically removing the RED +ve terminal from the battery. This will enhance Battery life. 18) Allow the refrigerator to operate for a period of twenty-four hours, then check that the chart recorder has maintained correct time. 19) Once all steps 1-18 of this manual have been performed, the refrigerator will now be ready to use.

Section 4 Alarm Test Sequence: With the TS1000 in Standby mode the green standby indicator will be illuminated and the display will indicate Alarm Armed : Press and hold the Test button for a few seconds, the buzzer will sound during this period and then the test sequence will begin. The TS1000 first checks the condition of the battery, during this time the power loss alarm and battery indicators will be illuminated. The indicator on the Test button will also be illuminated. TLS 10/10/07 8
If the battery condition is inadequate the test sequence will fail and the display will indicate Low battery. The test will have to be aborted and the battery replaced before continuing. Use the Hidden button to turn the TS1000 off (standby light out), this will remove the low battery alarm. Then after replacing the battery use the hidden button to place the TS1000 in standby again. If the battery condition is good the test sequence will continue and the Power loss alarm & Low battery indicators will flash for one minute before proceeding to the low alarm test. The TS1000 will cool the sensor down to the low alarm temperature of 2.5ºC. When the sensor reaches the low alarm temperature of 2.5ºC the buzzer will sound and the display will indicate a low temperature alarm: TLS 10/10/07 9
The TS1000 will then heat the sensor up to the high alarm temperature of 5.5ºC. When the temperature reaches 5.5ºC the buzzer will sound and the display will indicate a High Temperature Alarm. Use the Mute button to silence the buzzer at this time. TLS 10/10/07 10
At this time the test sequence is essentially complete. The sensor will cool down naturally below the 5.5ºC high alarm temperature within a few minutes. The display will then indicate that the test is complete, and the Test button indicator will be illuminated for 60 minutes. During this 60 minutes the test sequence cannot be started again. Section 5 Maximum & minimum logging: The TS1000 has an extra feature that allows the operator to view the minimum and maximum logged temperatures at the press of a button. The operator can also reset these temperatures whilst viewing them. To view the minimum logged temperature press the button once. Press the button again to view the maximum logged temperature. To reset either temperature, press the button whilst viewing the temperature. TLS 10/10/07 11
