    Pre-Installation Guidelines & Checklist Introduction Before any pelletizer can be installed, the owner/operator must prepare the site for installation and operation. It is the owner’s responsibility to verify all the necessary preparations have been made to the installation site and meet the specifications and guidelines detailed in this publication.

    Always transport the machine in the upright position using a forklift. Pick up the machine from the side with the forks fully engaged and adjusted to the maximum width (refer to "Figure 1: Transporting and Lifting the Machine."). Forklift Requirements PR120H PR350H PR750H Load Capacity 1000 kg (2205 lb) 1500 kg (3307 lb)

  • Page 8: Pre-Installation By The Customer

    Pre-Installation of the machine at the site must be carried out by the owner/operator. After that, a Cold Jet technician will arrive on-site for the final commissioning, start-up, and training. Machine owner/operators are responsible for the physical installation, utility connections, and supply required to put a new machine into service.
