Introduction
General description
Each unit is completely assembled, wired, evacuated, charged, tested, ready for installation. The main
components are air-cooled condensers with integral sub-cooler sections, accessible semi-hermetic single-screw
compressors, shell-and-tube evaporators, shell-and-tube water heat recovery condensers (optional), oil
separators, complete refrigerant piping and electrical panel (including control and power sections). Liquid line
components are shut-off valves, charging valves, filter-dryers, sight-glass/moisture indicators, electronic expansion
valves, liquid receivers (only with total heat recovery option). Other features are compressor heaters, evaporator
heater for low ambient water freeze protection, automatic pump-down during circuit shutdown and fully integrated
microprocessor control system.
The chiller uses R407C refrigerant and operates at positive pressures.
Purpose of the manual
The manual allows the installer and the operator to perform correctly all the required operations for unit installation
and maintenance without any damages to the chiller or to qualified personnel.
