The air discharge side should be free of restrictions. Recirculation of air is to be avoided. • The heat exchangers should not be connected to ducting on either the air inlet side or discharge side, unless the heat exchanger has been specifically designed for such an application. • Adequate distance from heat sources. • Adequate distance from sources of radio or electromagnetic emissions. • Noise within the limits permitted by applicable standards and regulations. • Adequate space and illumination must be left for maintenance operations and personnel. • Installation area free from oils, vapours and flammable gases. • Installation surface shall support the weight of the unit and minimize vibration transmission. Weight information and dimensions are listed on the product label and/or in the relevant product documentation. • Do not obstruct passageways or doors. • Coolers must be hung such that the coolers can contract and expand somewhat. Cooler contraction occurs during refrigeration operation, and cooler expansion occurs during defrost. For air coolers with copper tubing this figure runs up to 1.65 mm per meter cooler length. All heat exchangers must be set up level. • Hazards, position of controls and switch must be correctly signalled. Controls and switch must be positioned so that they are easily accessible and manageable. It is important to remember that the total amount of heat to be dissipated depends on receiving the full design air volume at the design entry air temperature which allows this air to be freely discharged after passing through the heat exchanger. Any restrictions may impair the performance of the cooler. If in doubt, please check with LU-VE Group. 3.2 Lifting Air coolers may be lifted by a fork lift. In doing so, ensure that the cooler is not lifted directly onto the drain tray or the finned coil. The forks must be long enough to enable lifting the cooler past its center of gravity. In the case of long, slim coolers extra attention must be paid to prevent the cooler bending. Utilizing the proper wooden transport beams and/or pallets prevents the cooler bending at the extremes such that the cooling circuit or other components are damaged. In principle, air coolers are not designed to be hoisted from above. In hoisting air coolers, lifting lugs must be used. To hoist long, slim coolers, a hoisting beam may be required to prevent possible bending at the extremes. All lifting procedures must be carefully carried out by properly qualified personnel, ensuring absolute safety at all times. If in doubt about the proper hoisting or lifting method, please check with LU-VE Group. Check the instruction manual for detailed lifting instructions about specific heat exchanger models. 3.3 Drainage The coolers' drain lines must have adequate fall. In freezer areas, drains must be equipped with an internal or external heating element to prevent freezing. Î All pipework should be adequately attached to the walls/ceilings of the cold room and not only to the cooler itself. Î The heater tape, if external, must provide heating right up to the casing (drain tray) of the cooler. Î Check all drain lines and drain trays to ensure that no improper material such as, e.g., packaging material blocks the drain. 3.4 Pipework and connections All pipework and connections must be made in accordance with good refrigeration design and installation practice. Ensure that no stresses are transmitted to the pipework. All pipework should be
