Repair Kits Available By Part Number Section 2 Page - GAMECO

WARNING: Installation, disassembly, repair and maintenance must
be performed only by qualified personnel.
Complete maintenance should be performed only after all gas has
been evacuated from the system and container. Remove the entire
valve before performing repairs.
Emergency service, on the actuator and lower stem assembly portion
of the valve only, may be carried out with the valve installed,
provided downstream pressure is relieved under the same conditions
required for releasing LP-Gas, as in the caution below. There
must be positive assurance that the valve is closed tight with no
leakage past the seats.
Installation, usage and maintenance of this product must be in
compliance with all Engineered Controls International, Inc. instructions
as well as requirements and provisions of NFPA #54, NFPA
#58, DOT, ANSI, all applicable federal, state, provincial and local
standards, codes, regulations and laws.
Inspection and maintenance on a periodic basis is essential.
Be sure all instructions are read and understood before installation,
operation and maintenance. These instructions must be passed
along to the end user of the product.
CAUTION: Contact or inhalation of liquid propane, ammonia and
their vapors can cause serious injury or death! NH3 and LP-Gas
must be released outdoors in air currents that will insure dispersion
to prevent exposure to people and livestock. LP-Gas must be
kept far enough from any open flame or other source of ignition to
prevent fire or explosion! LP-Gas is heavier than air and may not
disperse or evaporate rapidly if released in still air.
DISASSEMBLY AND REPAIR PROCEDURE
CAUTION: READ THROUGH ALL OF THESE INSTRUCTIONS, IN-
CLUDING THE NOTICE AND WARNINGS ON THE BACK OF THIS
SHEET, BEFORE BEGINNING ANY DISASSEMBLY OR REPAIR.
NOTE: Before repairing valve, thoroughly examine valve lever and all
associated parts for excessive wear. Check handle for proper function
and flange seating surfaces for excessive wear and damage. Any
components that are not in good condition and not fully operational
should be replaced during repairs.
Repairs must be performed in a clean area. Hands, clothing, tools and
work area must be completely free of oil, grease and foreign matter to
prevent contamination of component parts and valves.
MANUAL / PNEUMATIC ACTUATOR DISASSEMBLY
NOTE: The Standard A3219F Series is equipped with a manual actuator.
It is possible that the valve under repairs has been fitted with
a A3219FPA pneumatic actuator. Please follow the disassembly and
reassembly procedures for the appropriate actuator.
Manual Actuator Removal
A. Handle Removal
1. Remove cotter pin from jam pin which is located below the handle.
Discard cotter pin.
