Attachment 3 - Pre-installation guideline DIPH.pdf

This document is a Pre-Installation Guidelines & Checklist for Cold Jet's Dry Ice Production Hub, a 10-foot container system equipped with either a PR120H or PR350H pelletizer. The guide establishes the owner/operator's responsibility for site preparation and specifies comprehensive technical requirements across multiple utility and infrastructure categories prior to Cold Jet technician arrival for final commissioning and training.

The document outlines critical pre-installation requirements including CO₂ supply system specifications (liquid supply pressure 13-18 bar at -30°C to -20°C with fluctuation limits, vapor supply 150-300 psi, standard male JIC type connections), exhaust system design (maximum 2-3 psi static pressure with dedicated ducting and moisture drain capability), electrical service specifications (11 kW maximum consumption, 35 A Class J fuse protection, either EU 3×400 VAC or US 3×480 VAC configurations with four-wire three-phase power), compressed air supply (8-10 bar pressure with 150 L/min minimum flow for instrument air), and internet connectivity for Cold Jet Connect remote support. Additional requirements address operating environment conditions (36°F to 140°F ambient temperature, level floor with adequate load bearing), safety protocols regarding CO₂ hazards and dry ice handling, and relocation procedures. The document includes a pre-installation checklist requiring owner sign-off on CO₂ supply tank installation, pipeline systems, exhaust configuration, electrical compliance, documentation, and internet connection readiness before Cold Jet personnel commence on-site work.
