Introduction
1. Introduction
The Sabroe reciprocating compressor and unit can be configured with various types of equipment
depending on its function and requirements. Some of the equipment may be described in this
manual even though it is not featured on your particular unit.
This all-in-one manual provides all compressor information needed for sales, installation, mainte-
nance and service. Operating instructions and spare parts data are not included, but can be found
in the operating and spare parts manuals respectively.
The manual includes:
• Description of all component parts
• Description of all important technical functions to ensure a thorough understanding of the
product functionality
• Refrigerant safety
• Connecting data
• Installation, maintenance, service instructions
• and much more.
1.1 Main users
