WARNING The Compressor Module must be installed ONLY in systems that have been designed by qualified engineering personnel. The system must conform to all applicable local and national regulations and safety standards. These instructions are intended to assist in the installation and operation of the Compressor Module and MUST be kept with the Compressor. Service and maintenance of the Compressor Module must be performed by qualified technicians only. Service and maintenance must conform to all applicable local and national regulations and safety standards. Thoroughly review this manual, all instructions and hazard warnings before performing any work on the Compressor Module. Maintain all Compressor Module operation and hazard warning labels. WARNING Flammable gas can form explosive mixtures with air. Explosive gases can cause property damage, serious personal injury or death. WARNING Failure to disconnect and lockout electrical power from the Compressor Module before attempting maintenance can cause shock, burns, severe personal injury or death. WARNING Loosening or removing pressure-containing components from the Compressor Module when it is in operation can cause major property damage, serious personal injury or death. Failure to relieve system pressure prior to performing service or maintenance on the Compressor Module can cause property damage or serious personal injury. CAUTION Extreme heat can cause personal injury or property damage. CAUTION Always use a lifting device capable of supporting the full weight of the Compressor Module or component being lifted. Handling or lifting heavy assemblies can cause personal injury or property damage. Dual-Compressor Module Important Safety Information Safety Symbols Used in This Manual SAFETY ALERT SYMBOL When you see this symbol on the Compressor Module or in this manual, look for one of the following words and be aware of the potential for personal injury or property damage. WARNING A Warning describes hazards that CAN or WILL cause serious personal injury, death or major property damage.

The Compressor Module is designed for assembly into a Compressor Package ready for service in the field; the completed housing is done by equipment Packagers. This section provides an overview of these components. These terms are used throughout this manual: • Compressor Module - the SZO44 Compressor Module shown in Section 1.1 • Compressor - a Copeland Scroll® Compressor (two per Compressor Module) • Compressor Package - the entire assembly, including the Compressor Module, ready for service in the field • Packagers - the company that prepares the Compressor Module for service • VFD - Variable Frequency Drive used to power a variable speed Compressor Module 1.1 The Compressor Module The Compressor Module consists of two Compressors and the other components shown in Figure 1.
