This manual is intended to give the<br />
installer of this certifi ed engine all of the<br />
information that is necessary to properly<br />
install the engine and related components.<br />
Failure to follow these instructions when<br />
installing a certifi ed engine violates federal<br />
law (40CFR 1068.105(b)), subject to fi nes<br />
or other penalties as described in the Clean<br />
Air Act.<br />
Use of the correct engine fuel supply<br />
pressure is essential. It is the responsibility<br />
of the installer to install a fuel pressure<br />
regulator upstream of the engine and to<br />
verify the correct fuel pressure specifi ed by<br />
the manufacturer is supplied to the engine.<br />
After the fuel pressure has been set and<br />
verifi ed it is the responsibility of the installer<br />
to protect the fuel pressure setting from any<br />
further adjustment or tampering.<br />
Arrow cannot be held liable for any<br />
emissions noncompliance resulting from<br />
incorrect installation of this engine or failure<br />
to use the required settings.<br />
ALTITUDE ADJUSTMENTS<br />
Below are the adjustments required to the inlet fuel pressure for the certifi ed engines<br />
at various elevations to maintain the certifi ed emissions, eg: C-101 running 800 RPM at<br />
10,000' elevation the fuel pressure should be set at 3.5" WC, fi gured thusly - Standard fuel<br />
setting 5" WC + -1.5" WC = 3.5" WC<br />
