SECTION 4 – SYSTEM DESCRIPTION General The CMH air compressors are semi-packaged, air cooled units designed for power take-off applications. Each unit is designed to operate at ambient temperatures from - 10°F to 125°F (-23.3°C to 51.7°C). For the actual delivery of each unit at its rated operating pressure, refer to the typical General Data Decal supplied with each unit, and to the table in Section 5.

SECTION 5 - INSTALLATION Location After the type of drive is determined, satisfactory installation depends upon the ability of the installer. Refer to the appropriate foundation plan for the dimensions of the compressor package and the appropriate separator foundation plan for the dimensions of the combination primary oil separator tank- air receiver and the secondary separator tank (hereafter called the receiver separator).
Page 17
PIPING General As CMH Series compressors are comprised of two modules (compressor and separator), there is necessarily interconnecting piping between the two. These hoses are not provided with the units, as the required lengths of the hoses are dependent on the relative location of the two modules in their installed location.
