The following information is provided for your guidance: 1. Acceptance: Immediately upon delivery to you the product packaging and the product itself should be inspected for any signs of damage. It was perfect when it left us and should still be so when you receive it. If this is not the case please contact the supplier from whom you ordered it within three days of delivery. 2. Positioning: Units should be positioned so as to allow adequate airflow around the refrigeration compartment. Once in its final position for use, the equipment must be left to stand for at least 2 hours before being switched on to prevent damage to the refrigeration system. 3. Stabilisation: Following the above resting period the equipment can be switched on and left for at least 24 hours to cool down and the temperature to stabilise. After this time the unit should be checked for correct operation. Only after this should the product be used for the storage of material. 4.

OPERATING INSTRUCTIONS FOR LABCOLD LABORATORY FREEZERS MODEL RLVF08201 Read and follow these instructions carefully before use. Remove all internal packing materials and position the freezer away from all heat sources. Install your freezer with a minimum of 1 inch (25mm) clear space at the top and sides. To ensure a minimum of 3 inches (75mm) clear space at the back, fit the spacer provided in the envelope. The space must be clear to allow the warm air from the condenser, at the back of the refrigerator, to circulate freely. The cabinet should stand level or with a slight tilt backwards. The cabinet must not tilt forward as this could affect door sealing and closing. To ensure cabinet stands firmly on the floor, an adjustable foot is provided beneath the front corner. (A cold location is undesirable and may lead to condensation on the outer surface of the freezer). BEFORE STARTING Clean the interior of the freezer (see paragraph “Cleaning your freezer”). Check the voltage indicated at the back of your freezer conforms with your meter supply: failure to do so may invalidate the Guarantee. WARNING - This appliance must be earthed. IMPORTANT - The wires in the mains lead are coloured in accordance with the following codes: Blue - Neutral Brown - Live Green and Yellow - Earth A 3 - pin, 13 amp fused plug must be correctly fitted to the mains lead of your refrigerator and as three colours of the wires of the mains lead of your appliance may not correspond with the markings identifying the terminals in your plug, proceed as follows:Connect Green & Yellow coloured wire to plug terminal marked with letter ‘E’ or coloured Green or Green & Yellow. Connect Brown coloured wire to plug terminal marked with ‘L’ or coloured Red. Connect Blue coloured wire to plug terminal marked with letter ‘N’ or coloured Black. TO START Plug the mains lead of the freezer into a suitable earth socket. When switching on the freezer the green indicator should come on and remain illuminated. If the green indicator does not come on or goes out check that the unit is plugged in, the electricity socket is turned on and the fuse has not blown. The red warning indicator will illuminate when the unit is turned on for the first time, this will go out when the internal temperature reaches the required setting (see paragraph “Thermostat”). If the red warning indicator is illuminated at any other time check that the doors are shut correctly. Allow the freezer to operate for 24 hours to correct functioning before loading. DO NOT PUSH EXCESS MAINS LEAD INTO THE COMPRESSOR COMPARTMENT.

THERMOSTAT The internal temperature is controlled by a thermostat and the dial has 6 temperature settings, 6 being the coldest. The thermostat is situated under the control panel and is visible when the door is opened. For use in normal climatic conditions and general laboratory locations it is recommended that the dial should be set between 3 and 5. Such factors as location, room temperature frequency of door opening and frequency of defrosting will affect your freezer temperature and the cold control might have to be varied to allow for these. FAST FREEZE After defrosting, or when the freezer is first turned on, there is a fast freeze feature, which will cool it down quicker, enabling it to be used sooner. The fast freeze feature will make the freezer colder (approximately -28ºC) than the normal operating temperature of -18ºC. In order to activate the fast freeze turn the thermostat dial to 6. This feature does not cancel automatically and the thermostat dial will have to be reset to the normal operating temperature. The fast freeze feature should be used sparingly to conserve energy.

DOOR Door opening is by a pull handle. A light touch on the door should be sufficient for it to close firmly. A little extra pressure may be required according to the door loading. The magnetised door gasket around the door liner provides an effective seal when the door is closed.

DEFROSTING A heavy frost deposit on the inside of the freezer compartment is undesirable because ice acts as a form of insulation and affects freezing performance. To maintain efficiency the ice must be removed whenever a heavy layer has built - up. Scrape off the frost with a wooden or plastic scraper. Collect the removed frost and throw away. DO NOT use a sharp instrument to remove frost. It may cause expensive damage. For a complete defrost, unplug the freezer and remove all samples and store in a cool place. The tray supplied should be taken from the bottom of the freezer and with the small basket removed, slide into position under the bottom freezing shelf. A suitable container should then be placed under the hole in the tray to collect the defrost water. Defrosting should be carried as quickly as possible. It can be assisted by placing a bowl of hot water in the freezer, and closing the door as far as possible. On NO account use electrical heaters such as hairdryers, fires or hot air blowers. Check periodically that all the frost has melted and when this is so, remove the bowl of hot water, mop out any remaining defrost water and clean as instructed in the following section. Replace the tray and basket and restart the freezer. When the cabinet has reached its operating temperature, replace the samples. CLEANING YOUR FREEZER The cleanliness of your freezer is as important to your samples as maintaining proper temperatures. Your freezer is easy to clean and to keep clean. EXTERIOR Use a silicone liquid wax polish, which will clean and polish the cabinet in one easy application. Do not use aerosol polishes as the spray may damage the plastic parts. CAUTION Do not use waxes, which contain ammonia, as they tend to discolour the finish. INTERIOR Your freezer interior should be wiped with a soft cloth dampened with a solution of one teaspoonful of bicarbonate of soda, to one quart of water. Rinse with clean warm water and dry thoroughly. Do not use scouring powders, bleaching agents, solvents, acids, metals or nylon sponges when cleaning any part of your freezer. Metal polishes, waxes or furniture creams must not be used to clean the interior as damage to plastic surfaces will result. SERVICE Before calling for the Service Engineer, which could be expensive: 1) 2) 3) 4) 5) 6)

Make sure the mains cable from the freezer is correctly connected to the power point. Check the mains switch is “ON”. Check the fuse is intact. See that the cold control is correctly set. Ensure that your freezer has air circulation behind and above. Close freezer door firmly and check gasket sealing.

USEFUL HINTS Ensure that when your freezer is to be out of Service for any length of time that the interior is carefully cleaned and dried, door left open and plug disconnected from mains socket. Carry out cleaning regularly. See that vibration noises are not caused by objects in contact with your freezer and each other. In the event of a breakdown call our Service Department on 0870 300 1002 INSTR:G
