WARNING: Installation, disassembly, repair and maintenance must<br />
be performed only by qualified personnel.<br />
All gas MUST be evacuated from the system before starting<br />
repairs. Remove the entire valve before performing repairs.<br />
Emergency service, on the actuator and lower stem assembly<br />
portion of the valve only, may be carried out with the valve installed,<br />
provided downstream pressure is relieved under the same conditions<br />
required for releasing LP-Gas, as in the caution below, and<br />
that there is positive assurance that the valve is closed tight with<br />
no leakage past the seats.<br />
Installation, usage and maintenance of this product must be in<br />
compliance with all Engineered Controls International, Inc. instructions<br />
as well as requirements and provisions of NFPA #54, NFPA<br />
#58, DOT, ANSI, all applicable federal, state, provincial and local<br />
standards, codes, regulations and laws.<br />
Inspection and maintenance on a periodic basis is essential.<br />
Be sure all instructions are read and understood before installation,<br />
operation and maintenance. These instructions must be<br />
passed along to the end user of the product.<br />
CAUTION: Contact or inhalation of liquid propane, ammonia and<br />
their vapors can cause serious injury or death! NH3 and LP-Gas<br />
must be released outdoors in air currents that will insure dispersion<br />
to prevent exposure to people and livestock. LP-Gas must be kept<br />
far enough from any open flame or other source of ignition to<br />
prevent fire or explosion! LP-Gas is heavier than air and may not<br />
disperse or evaporate rapidly if released in still air.<br />
Disassembly and <strong>Repair</strong> Procedure<br />
CAUTION: READ THROUGH ALL OF THESE INSTRUCTIONS, IN-<br />
CLUDING THE NOTICE AND WARNINGS BEFORE BEGINNING ANY<br />
DISASSEMBLY OR REPAIR.<br />
NOTE: Before repairing valve, thoroughly examine valve lever and all<br />
associated parts for excessive wear. Check handle for proper function<br />
and flange seating surfaces for excessive wear and damage. Any<br />
components that are not in good condition and not fully operational<br />
should be replaced during repairs.<br />
<strong>Repair</strong>s must be performed in a clean area. Hands, clothing, tools and<br />
work area must be completely free of oil, grease, and foreign matter to<br />
prevent contamination of component parts and valves.<br />
Manual/Pneumatic Actuator Disassembly<br />
NOTE: The standard A3217F Series is equipped with a manual<br />
actuator. It is possible that the valve under repair has been fitted with<br />
a A3217FPA pneumatic actuator. Please follow the disassembly and<br />
reassembly procedures for the appropriate actuator.<br />
Manual Actuator Removal –<br />
1. Remove the cotter pin from the handle/stem assembly that is<br />
located in the outer most area of the stem. Discard cotter pin.<br />
2. Loosen and remove steel bolt from the stem. Save bolt and washer<br />
for reassembly.<br />
3. Remove handle from stem. Save handle for reassembly.<br />
Pneumatic Actuator Removal –<br />
1. Remove cotter pin from pivot pin, located behind the clevis, and<br />
discard. Remove the pivot pin and washers. Save parts for<br />
reassembly.<br />
2. To remove crank arm, first remove cotter pin from crank arm and<br />
discard. Rotate the crank arm counterclockwise until the leg clears<br />
the clevis. Pull the crank arm off the stem. Remove nylon washer.<br />
Retain all parts.<br />
3. Remove and retain bracket screws and bracket lock washers. The<br />
actuator bracket can now be removed and saved.<br />

4. Lubricate the three (3) new stem seal rings, new jam ring and stem<br />
washer. Assemble these one piece at a time over the stem and into<br />
the seal gland. Be careful not to damage any pieces on the flat<br />
