The unit must remain on the container floor for at least 1 m. The space between the unit and the roof of the container is reduced. Contact with the roof can cause damage to the unit. With a second forklift (identified by letter B), insert the forks (under the centre of gravity) and slightly lift the unit. Remove hooks and chains and drive away with forklift A. Slowly drive forward with the truck until the unit is completely outside the container. 30366473EN-09 Alfa LU-VE is a trademark registered and owned by LU-VE Group.

Page 15: Mounting Dimensions
To avoid oxidation of the equipment feet, it is strongly recommended to mount the heat exchanger on concrete mounting bases. One base for each foot. Base minimum dimensions are 100 mm height and 260 mm width. Expansion joints (only for condensers) Alfa LU-VE recommends the installation of expansion joints on both inlet and outlet con- nections. Expansion joints are elastic elements which, if properly installed, absorb the thermal expansions of the tubing. Expansion joints are also helpful in order to reduce vibrations in the piping. 30366473EN-09 Alfa LU-VE is a trademark registered and owned by LU-VE Group.

Page 19: Operation
• Switch on fan power supply. • Start the fans and verify fan direction. • After some operating time, verify that current absorbtion does not exceed the value as given in the technical specifications. Shutdown If the unit requires emptying for maintenance, system shutdown or dismounting, proceed as follows: • Stop refrigerant supply and switch off electrical power supply. • Make sure neither refrigerant nor power supply can be resumed accidentally or unexpectedly. • Drain all liquid refrigerant into a suitable vessel. • Evacuate the coil to remove any remaining refrigerant gas. 30366473EN-09 Alfa LU-VE is a trademark registered and owned by LU-VE Group.
