UNPACKING Remove the equipment from the packing material and check for damage. Notify the detail of any damage to your supplier or to Thermoline Scientific without delay. Retain the packing materials until the equipment has been thoroughly tested. Inventory: • Shelves and shelf support clips include std quantities. • 1 x 3-pin plug for connection of alarms to remote Building Monitoring System (BMS). • Door keys. • Chart recorder keys and paper. (Only if optional chart recorder is supplied).
USE & FUNCTION The Thermoline range of Laboratory refrigerators are designed to store temperature sensitive products within an adjustable temperature range. This product is identified by a label on the front of the unit as shown below:
Laboratory Refrigerator This products’ intended use is for the storage of temperature sensitive products. It CANNOT be used as a pharmacy or vaccine refrigerator. All TELR/TLR Refrigerators have loading requirements. When loading, product should be evenly distributed throughout the refrigerator. It is important to leave 1/3 of each shelf level free (3cm front, side, rear and between products) this allows air to flow evenly throughout the cabinet and maintain temperature accuracy in the refrigerators workspace. The digital temperature control monitors product temperature, and includes a temperature logging feature that allows the operator to determine the maximum and minimum temperatures reached during daily operation. When correctly maintained, the refrigerator has an expected lifespan in excess of 5 years. Regular maintenance and checks by a licensed refrigeration technician will help extend the life of the unit. The display also incorporates the HI/LO temperature alarms emitting both visual and audible signals, which can also activate a building monitoring system (BMS), via a connection socket on the cabinet. High temperature alarm set at 1ºC above setpoint. Low temperature alarm set at 1º C below setpoint. Operating temperature set between +4 & +10º C. These cabinets will operate from a standard 10 amp, 240 volt, 50Hz, general purpose outlet (power point). Cooling is by means of a hermitically sealed refrigeration unit using environmentally friendly refrigerant. Fan forced air circulation internally ensures that even temperature conditions are obtained on all shelf levels. The controller monitors the temperature inside of the workspace. The control sensor is located in a bottle that simulates product, this give a more accurate reading of the temperature inside of the workspace.

LOCATION & INSTALLATION
All refrigerated equipment generates heat as part of the normal operation. It is vital for correct performance and reliability that adequate ventilation is provided to allow this heat to dissipate.
I
Any refrigerated equipment that is operated in a small unventilated area, especially in warm weather, can cause the compressor to overheat and may result in premature failure. NOTE: Failure to observe ventilation guidelines will void the manufacturer’s warranty! All TELR/TLR Refrigerators require ventilation around them. 100mm (10cm) on each side and the back is required. See diagrams below showing correct placement and ventilation distances.
TELR 130, 145
TLR 520, 750, 950, 1150
TELR 200, 440, 740
Do not store items on top of the fridge as this will also affect ventilation! Level: The cabinet should be standing on level ground to ensure correct operation of the self-closing door, and proper draining of condensate from the evaporator (internal cooling surface). Castors: Where lockable castors are fitted they must be locked to prevent accidental cabinet movement. This can be achieved by pressing the lock-down tab with your foot. Ensure that both castors are locked. Mains connection: This cabinet is suitable for connection to a standard 10Amp, 240 volt, 50Hz, supply. A dedicated outlet should be used for the supply, do not use power boards or the like. A 3-pin moulded plug is fitted as standard to the mains lead.

OPERATION 1: Locate the cabinet as previously described, and plug the mains lead into the power supply but do not turn the power on just yet. 2: The cabinet is supplied with the shelves fixed in place. Adjust the shelf positions to suit your storage needs by moving the support clips provided. 3: Turn on the power and the circulating fan inside the cabinet will start immediately. You should also be able to turn on the internal light using the “light” switch on the front panel. 4: After a short warm-up period, the temperature control will display the temperature inside the refrigerator. The refrigeration compressor will start after a few minutes. 5. Allow the cabinet to reach operating temperature and to operate for at least 8 hours prior to loading stock.

CONNECTION OF ALARMS As previously mentioned, this cabinet is fitted with a 3-pin socket on the cabinet to allow for connection to a building monitoring system (BMS), or to a phone dialer. A plug is also supplied separately to connect the socket to your wiring. The alarm contacts have no voltage present, but we recommend that the wiring is connected by a suitably qualified technician (electrician or similar). An alarm can be triggered by one of the following conditions: • Loss of power. • High temperature inside the refrigerator (1ºC above setpoint). • Low temperature inside the refrigerator (1ºC below sepoint). *Normally Closed Will open loop upon alarm situation (No 1) *This is the optimum option as any break in the loop is detected.
Normally Open Will close loop upon alarm situation (No 2)
Common At least one wire is connected to this pin (No 3)
LOADING All forced draught refrigerators such as this one requires constant air flow throughout the cabinet to maintain the desired temperature. Correct loading of the shelves must be considered for efficient refrigeration performance. • Never block off air vents in the rear panel if fitted. • Allow air space around the product on each shelf. • Distribute the load evenly over all of the shelves rather than stacking everything on one shelf. • Whenever possible the load should be chilled prior to loading to reduce the effect on the temperature inside the refrigerator. If this is not possible then load the product a little at a time.
I
• All TELR/TLR Refrigerators have loading requirements. When loading, product should be evenly distributed throughout the refrigerator. It is important to leave 10% of each shelf level free (3cm front, side, rear and between products) this allows air to flow evenly throughout the cabinet and maintain temperature accuracy in the refrigerators workspace.
CALIBRATION Calibration of the unit ensures correct product temperature and optimal refrigerator perfrormance. Calibration should be done by a trained technician. Press and hold
+
the following parameters will be available
Ot - Sensor Offset in Bottle OE - Return Air Sensor Offset O4 - Low Temp Alarm Sensor Offset dP1 - Current Temperature of the Bottle Sensor dP2 - Current Return Air Temp
Calibration is normally performed at 5°C. This procedure is a standard procedure used by Thermoline Scientific. The aim when calibrating a Thermoline Laboratory Refrigerator is to have the Bottle at 5°c. This is acheived by placing a reference sensor in the bottle or in a bottle adjacent to the units bottle and noting the indicated temperature. The OE parameter is then adjusted to increase or decrease the air temperature until the reference sensor reads 5°c. Once the reference sensor has an average temperature of 5°c adjustments to Ot are made so that dP1 (Display Temperature) equals 5°c. Copyright 2018 Thermoline Scientific Equipment Pty Ltd

TEMPERATURE LOGGING The digital temperature control has a feature that allows the operator to log or record the maximum and minimum temperatures attained by the cabinet over a period of time. These logged temperatures can be reset on a daily basis by simply pressing the buttons on the face of the instrument as follows: i) ii) iii) iv)
Press and release the “UP” button until ‘Hi’ appears. This is ‘MAX’ temp logged. Press and hold the “SET” button until RST appears the maximum logged temperature will then be reset. Press and hold the “DOWN” button until ‘Lo’ appears. This is ‘MIN’ temp logged. Press and hold the “SET” button until RST appears the maximum logged temperature will then be reset.
OPTIONAL CHART RECORDER (IF FITTED) A circular chart recorder can be factory fitted as an optional extra. The recorder has a seven day chart with a battery back-up that will keep the chart running for at least twenty four hours in case of a power failure. To set the time: • Unlock the recorder door using the key supplied. • Raise the nib off the chart paper by pushing the lever at the top right corner. • With the pen nib lifted off the paper, insert a coin into the slot in the centre of the spindle, and turn it ANTICLOCKWISE ONLY! • Note: It is easier to set the time when the refrigerator is at the set temperature, this will enable you to determine the time more accurately. • Carefully remove the pen nib cover by gently turning it as you pull it off the nib. • Lower the nib onto the chart and close the clear lid with the key provided.
To replace the chart paper (weekly): • Raise the nib off the paper by pushing the lever at the top right corner. • Replace the chart paper by simply pulling the edges of the chart out from under the three locating tabs. • Place the new chart over the slot in the spindle taking care not to tear the chart as you do it, and fit the outer edges of the chart back under the locating tabs to keep it in place. • Lower the nib onto the chart and close the door using the key provided.
OPTIONAL LOW TEMPERATURE PROTECTIVE CUT-OUT (LTPC) (IF FITTED) Low Temperature Protective Cut-out: As an added safety feature the refrigerator can be factory fitted with a low temperature protective cut-out, which is factory set and not adjustable, to stop the temperature inside the refrigerator from falling below 0ºC. This is particularly important in the storage of vaccines which can be destroyed if frozen. The cut-out operates independently from the temperature control and turns off the compressor at +1 to +2ºC. In this way, should the controls fail in a “cooling” condition; the product will be protected against freezing. For testing and calibration of the LTPC contact your service technician.

CLEANING & MAINTENANCE General cleaning: The interior, exterior, and door gasket can be cleaned as often as required using a soft cloth and soapy water. Never use abrasive cleaners or scouring pads as these will scratch the surface and may result in corrosion. Never use caustic type cleaning agents.
I
All cabinets have electrical components such as the temperature control, internal light, refrigeration condensing unit. These items should not be subjected to any levels of moisture. For example, do not use a hose to wash down the refrigerator. Evidence of moisture entry into any electrical device will void the manufacturer’s warranty!
Maintenance: Apart from normal levels of cleanliness, it is important that the refrigeration condenser is kept clean and free from dust. Failure to keep the condenser clean could lead to higher temperatures inside the cabinet, higher running costs, and often a failure of the compressor. A clean condenser is a critical factor in keeping the refrigerator operating correctly. The condenser should be cleaned at least every 6 months, in some dusty locations this may need to be more frequent. By monitoring the amount “clogging” due to dust, the frequency of cleaning can be adjusted to keep it clean. Manufacturer’s warranty does not cover the failure of the compressor due to a blocked condenser. Procedure for cleaning the condenser: • The condenser is located in different areas depending on the model. The TELR-145 condenser is located on the rear of the unit as seen in the first image below. TELR 200, 440 & 740 have a cover at the base of the cabinet which can be removed to access the condenser for cleaning. The cover unclips from the bottom and has two locating pins at the top to secure it in place. The TLR range have the condenser located at the top of the cabinet behind the front panel. To remove this panel, push upward and pull it away from the cabinet.

• Turn off the power at the power point before cleaning the condenser! • Using a stiff paint brush, carefully remove dust and dirt build-up from the condenser, ensuring that dust is not pushed back into the condenser fins. The use of a vacuum cleaner will help in cleaning up the dislodged material.
I
• The condenser fins may be sharp, take care to avoid personal injury by not directly contacting them with your hands! • The fin material is thin and can be easily bent, take care not to flatten the fins as this may affect the efficiency of the condenser.
