SAVE THESE INSTRUCTIONS

CAUTION:

The vessel manufacturer must comply with the requirements
of CFR 40 1060.202. Any questions can be directed to www.
attwoodmarine.com

Failure to follow these instructions may result in accidental
fuel system over-pressurization. Users must follow these
instructions to ensure vessel function and operation

EMISSION-RELATED INSTALLATION INSTRUCTIONS

Failing to follow these instructions when installing the Attwood
Carbon Canister System Direct Fill in a piece of nonroad equipment violates
federal law (40 CFR 1068.105(b)), subject to fines or other penalties as
described in the Clean Air Act.

FEATURES:

The Attwood Carbon Canister System Direct Fill is sturdy, non-corrosive plastic. Bonding
and grounding are not required because they are non-metallic. The Direct Fill cap is water
resistant when secured correctly; turned until an audible sound is heard. They meet all
requirements for ISO 10080, ABYC, and USCG.

The Carbon Canister Direct Fill is not certified for diurnal emission control. The use of a
certified Carbon Canister for proper diurnal emission control is required to meet EPA diurnal
emission control requirements. The Attwood Direct Fill is equipped with over pressure relief
valve. This valve is intended only to prevent the accidental over pressurization of a fuel
system and is a safety device only, not for use as diurnal emission control devices.

MOUNTING LOCATION AND REGULATIONS

Select location that meets these conditions:

1. Conforms to all ABYC, U.S. Coast Guard, and EPA regulations. (See end of this document

wrench is acceptable.

2. Pressure test tank to ensure connection integrity, per CFR 33 183.580, at a pressure
of 3 psi for no less than 5 minutes. Inspect all connections for leak by method other
than pressure decay.

3. If leaks occur, rotate the cap clockwise until the second Anti-Backout tooth clicks past
the tab. (prefered position)

4. Pressure test tank to ensure connection integrity, per CFR 33 183.580, at a pressure
of 3 psi for no less than 5 minutes. Inspect all connections for leak by method other
than pressure decay.

5. If a leak occurs, rotate cap clockwise until the third Anti-Backout tooth has clicked
past the Tab.

past the Tab.

8. Pressure test tank to ensure connection integrity, per CFR 33 183.580, at a pressure
of 3 psi for no less than 5 minutes. Inspect all connections for leak by method other
than pressure decay.

CARE AND MAINTENANCE

Care should be taken, when cleaning the boat, to prevent contaminating the valves and direct
fill. Cleaning with only mild soapy water is recommended. All connections should be checked
annually.

MANUFACTURER REQUIREMENTS

The information below applies only to EPA CFR 40 1060.135. The vessel manufacturer is
responsible to meet all additional regulatory labeling requirements including EPA, CARB,
USCG and others as necessary. The below information is for reference only. The vessel
manufacturer should refer to CFR 40 for complete labeling guidelines.

In order to meet the requirements of CFR 40 1060.135, the vessel must be labeled with respect
to evaporative emissions in the following manner when installing certified components;

Excerpt from CFR 40 1060.135

(a) You must affix a permanent and legible label identifying each engine or piece of equipment before
introducing it into U.S. commerce. The label must be—

(1) Attached in one piece so it is not removable without being destroyed or defaced.
(2) Secured to a part of the engine or equipment needed for normal operation and not normally requiring
replacement.
(3) Durable and readable for the equipment’s entire life.
(4) Written in English.
(5) Readily visible in the final installation. It may be under a hinged door or other readily opened cover. It
may not be hidden by any cover attached with screws or any similar designs. Labels on marine vessels
must be visible from the helm.

(c) If you produce equipment without certifying with respect to evaporative emissions, the equipment label
specified in paragraph (a) of this section must—

(1) State: ‘‘MEETS U.S. EPA EVAP STANDARDS USING CERTIFIED COMPONENTS.’’
(2) Include your corporate name.

Below is an example of a label specified by CFR40 1060.135 for use with certified components;
