Champion R Series Operation & Service Manual page 14

Installation (continued)
Do not install isolating valves between compressor outlet and air receiver. This will cause excessive
pressure if valve is closed, and cause injury and equipment damage.
Always use an air pressure regulating device at the point of use. Failure to do so can result in injury
or equipment damage.
● Do not install in an area where ambient temperature is below 32°F or above 104°F.
● Do not install unit in an area where air is dirty and/or chemical laden.
AIR LINE PIPING
Connection to air system should be of the same size, or larger, than discharge pipe out of unit. The table
gives recommended minimum pipe sizes. A union connection to the unit and water drop leg is
recommended. Install a flexible connector between the discharge of the unit and the air piping. Piping
should be periodically inspected for leaks using a soap and water solution for detection on all pipe
joints. Air leaks waste energy and are expensive.
