Page 8: Transport And Storage
Transport and storage During transportation the heat exchanger must be handled with all required care. Any instruction or warning signs attached to the heat exchanger or the packaging must be followed. Avoid shocks or continuous vibrations during transport. These may cause damage to the product. If required, consult Alfa LU-VE and disassemble during transport any parts that are likely to be set into vibration. - Page 9 Ensure that the cooler is not lifted directly onto the driptray or the finned coil. 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. Lift the unit to mounting position and secure following instructions given in chapter "6...

Page 12: Refrigerant Connections
Refrigerant connections Do not adapt headers position to the suction line. 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 adequately attached to the walls/ceilings of the cold room and not only to the cooler itself. -
Page 13: Pressure Test
Pressure test Ts1=cold room air inlet temperature. Te=evaporating temperature. It is related to the refrigerant pressure on the unit cooler outlet. Trs=refrigerant superheat temperature, on suction line near thermostatic valve bulb. (Trs-Te)=superheat (Trs-Te) ≤ 0.7 x (Ts1-Te) Keep the superheat as low as possible to obtain maximum unit cooler performance. -
Page 14: Electrical Connections
Electrical connections All electrical connections must be made in accordance with the locally valid regulations and in conformance with good installation practice. The site supply voltage, frequency, accepted power rating and number of phases must comply with the details on the technical documentation. All electrical supply lines must be connected to the terminal boxes through suitable waterproof glands using bottom entry or, in case of horizontal installation, the cable is routed to form a water trap. -
Page 15: Fan Motors Connections
Fan motors connections The maximum load of the motors and the recommended settings for the overload relays are to be respected. The electrical control circuit should be arranged with a manual reset device in order to prevent continuous on/off switching (tripping) of the motors. Suppliers and manufacturers of electrical motors provide no guarantee for motors that are combusted through overload. -
Page 16: 6.10 Defrost
6.10 Defrost Always refer to the electrical scheme for both connections and nominal voltage of the electrical defrost option. Earth cable must always be wired and connected to the appropriate terminal in the connection box. Always refer to the electrical scheme order to identify the ground terminal. Warning about the neutral wire: it must be connected if indicated in the electrical scheme. - Page 17 FMS30 Model No. fans Coil type connection scheme FMS30 FMS30 1130 FMS30 1200 FMS30 1755 FMS30 1400 FMS30 2130 FMS30 2070 FMS30 3130 FMS30 2740 FMS30 4130 1~230 V - 50/60 Hz fixing clip fixing clip driptray driptray 31592031EN-01 Alfa LU-VE is a trademark registered and owned by LU-VE Group.

Page 19: Maintenance
Maintenance It is essential after delivery that adequate protection and inspection are carried out on the equipment. This is especially important if there is any delay in installing or commissioning the equipment. After commissioning and setting up the defrost systems, the heat exchanger will require maintenance. -
Page 20: Electric Defrost Elements Replacement
Electric defrost elements replacement Before handling heater elements always: • disconnect power supply • ensure heaters are at ambient temperature. Disconnect drain line. Open the driptray and side covers on both sides. Open side covers. Remove fixing clips (T), disconnect heater elements from connection box (P) and extract elements (E). -
Page 21: Fans
Fans Fans should be checked 3 months after commissioning and thereafter depending on operating conditions and as experience dictates, for any dirt build-up and/or unusual vibration, which could ultimately cause damage to the fan or to the heat exchanger itself. Ensure complete electrical isolation before removing fan guards. -
Page 22: Residual Risks
Residual risks Sharp edges & corners • There is a substantial risk of injuries due to sharp edges and corners of coil and casing. Make sure to wear reliable protection during any handling of the unit and maintenance activities. • Drip tray Ensure the drip tray is empty before lowering or disassembling. -
