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.
