About this Manual This user Manual contains instructions which must be followed in order that the product is operated correctly. General Notes Please observe the following safety precautions: 1. Fill the tank prior to connection to power supply. 2. Connect only to a power supply with the corresponding voltage to that specified on the rating label positioned on the rear of the unit. 3. Ensure the power supply has a safety earth (ground) terminal. 4. Ensure the mains switch and power supply connector are accessible during use. 5. The mains supply cord fitted to this products is a heat resistant type and should be replaced by an equivalent type. 6. Do not block ventilation slots during use and follow installation instructions. 7. Always follow good laboratory practice by ensuring substances being heated present no risk of a hazard (explosion, implosion or release of toxic or flammable gases) or that these have been addressed. When heating substances where liberation of gases occurs suitable extraction should be used. 8. Use only liquids specified in this Instruction Manual within their specified temperature range. 9. Use caution when topping up or draining the tank as the liquid in the tank may be very hot or cold. Allow the liquid to cool to 40°C before draining. 10. Drain before moving the bath. 11. Recommend using a Lid above 60°C. Take care when lifting the lid - steam and hot vapours can cause scalding. 12. Use a thermometer to check the temperature - do not touch liquid. 13. If this product is not used in accordance with these instructions, then basic safety protection afforded by the water bath may be affected. 14. Before using any cleaning or decontamination method except those recommended, check with your distributor that the proposed method will not damage the equipment.

Location The surface on which the product is to be located should be smooth, level and sturdy. Use in a ventilated room. Ambient room temperature 5°C to 40°C. Maximum humidity 80% for temperature 31°C decreasing to 50% at 40°C. Product is designed for laboratory use. Unpacking Remove the product from its packaging. Any damage to the product notify your dealer immediately. Retain packaging over warranty period. Contents consist of a bath, stainless steel false base, power lead and instruction manual. Safety Do not touch any electrical contacts or open any closure panels RISK OF ELECTRICAL SHOCK! Assembly Place the false base inside the bath. Fit the power lead into the socket at rear. Power Supply Before attempting to connect the product to an electrical supply check the information on the rating label is compatible. IF IN DOUBT CONSULT AN ELECTRICIAN. THE PRODUCT MUST BE EARTHED!. Where the mains supply or plug differs refer to local regulations or qualified electrician. Liquid Level - NE1 range Minimum liquid level - must cover the top of the false base by 40mm Maximum liquid level - must not exceed the ridge in the tank. Always ensure the product is disconnected from the electrical supply when emptying and filling. Suitable Liquids - NE1 range Operating temperatures from ambient +5°C to 99°C, for general use we recommend either: Distilled water. Heat transfer liquid [The LB range is formulated for temperatures from -45°C to 90°C and provides complete protection from freezing and algae growth and safeguards against corrosion. See accessories for the full range available]. VIRKON dissolved in distilled water has proven efficacy against bacteria (including mycobacteria), viruses, spores and fungi in a variety of independent tests using different protocols. Liquid Level - NE1B range Minimum and maximum water level is governed by the constant level which maintains water level during boiling. Using standard laboratory tubing, connect to the bottom outlet of the constant level to a regulated water supply/tap, adjust the water supply to provide a slow feed of water and maintaining boiling and this automatically maintains safe water level. The side outlet acts as an overflow to a sink or drain. Suitable Liquids - NE1B range Normal tap water is suitable since a maintained water supply is required. 4

Cleaning General cleaning Important - please follow these instructions to avoid possible damage to the unit, otherwise affect its performance and or warranty. Disconnect the product from the electrical supply before cleaning. The water bath must be cleaned at regular intervals wiping casework with a cloth or sponge soaked in warm soapy water. The stainless steel crevice free tank with smooth corners should provide years of valuable service and is resistant to chloride containing solutions it is however important to avoid high concentrations of halogens - especially chloride. With such a high quality and resistant tank it may show symptoms of these halogens as rust, which are deposits from external sources in the water supply. We recommend always empty the bath of liquid after use and wipe out the internal faces of the tank with a non-abrasive cloth and allow to dry. Any deposits can be removed with nitric acid (10%) on a cloth. WEAR PROTECTIVE EQUIPMENT! It is also recommended to use an accessory lid to prevent contaminates landing in bath liquids. Descaling Descale the stainless steel tank regularly to maintain it in as new condition ensuring the corrosion resistance and normal operating conditions are maintained throughout its working life. Descale by adding 1 litre of vinegar to water and gently heating to 50°C for an hour, empty, and brush the lime away. Rinse thoroughly afterwards. Virucidal Disinfectant We recommend Virkon a powder product for the safe and rapid disinfection of surfaces and equipment in a wide variety of situations available from your distributor.. VIRKON is dissolved in water for use, providing a safe working solution with a faint lemon odor. It has proven efficacy against bacteria (including mycobacteria), viruses, spores and fungi in a variety of independent tests using different protocols. Presents no serious long term health risks to staff – obviating the need for costly ventilation equipment and health monitoring. Also provides high level disinfection of laboratory equipment and instruments where autoclaving is neither practical nor necessary. The ultimate high level surface disinfectant. Its chemistry is a balanced stabilized blend of peroxygen compounds, surfactant, organic acids and an inorganic buffer system. Mode of action is by oxidation of proteins and other components of cell protoplasm, resulting in inhibition of enzyme systems and loss of cell wall integrity. Virkon is Registered in accordance with the requirements of the Medical Devices Directive, (93/42/ EEC) as a Medical Device.

FITTING ACCESSORIES FOR NE2D SERIES GRP GABLE LIDS Position the lid over the bath and lower into place. The lids are designed to fit snugly so that condensate runs into the bath. STAINLESS STEEL GABLE LIDS Position the lid over the bath and lower into place. These lids have bo drip points, provide full working height across the bath when fitted and have a ventilation gap. For “H” suffix lids place the lid onto the bath with the hinges hanging over the rear of the water bath aliigning with threaded bushes. Insert two screws provided into each hinge and tighten screws. The lid can be raised and lowered using the handle on the side. STAINLESS STEEL FLAT LIDS Position the lid over the bath and lower into place. STAINLESS STEEL FLAT LIDS WITH CONCENTRIC RINGS Position the lid over the bath and lower into place. Each set of rings can be used to vary the diameter of aperture to accommodate different sizes of vessels of evaporating dishes and glassware, including round-bottom flasks. STAINLESS STEEL TEST TUBE RACKS Place the loaded test tube rack into the bath on top of either the stainless steel perforated shelf or the raised shelf. Note: 4 Litre = 1 Rack, 8 Litre = 2 Racks, 14 Litre = 4 Racks, 22 and 28 Litre = 6 Racks HEAT TRANSFER FLUID Use as a ‘neat’ liquid solution for best results. THERMOMETER CLIP This can be positioned anywhere on the perimeter of the bath by cliping over the edge. The thermometer then lies flush with the top edge of the bath to prevent accidental damage. DRAINING SYPHON Allows the easy and quick emptying of any water bath. Water temperature must be below 45°C before emptying can commence. DRAIN TAP A drain tap outlet is featured on the 22, 28 and 56 litre sizes. Make sure the bath is empty, hold the outer nut, then using a socket/allen key undo the threaded insert. Once removed and still holding the outer nut, screw in the accessory drain tap into position and pinch tight. POLPROPYLENE SPHERES Place on top of the water/oil to provide a floating lid reducing evaporation and insulating the bath reducing heat losses. The range of Unstirred water baths: 4 litre bath requires 1 pack; 8 litre bath requires 2 pack; 14 litre 2 packs and 9, 22 and 28 litre requires 4 packs.
