WARNING: Installation, usage and maintenance of this product must<br />
be in compliance with all Engineered Controls International, Inc.<br />
instructions 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. Installation<br />
and maintenance should be performed only by qualified personnel.<br />
Be sure all instructions are read and understood before<br />
installation, 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 their<br />
vapors can cause serious injury or death! NH3 and LP-Gas must be<br />
released outdoors in air currents that will insure<br />
dispersion to prevent exposure to people and livestock. LP-Gas must<br />
be kept far enough from any open flame or other source of ignition to<br />
prevent fire or explosion! LP-Gas is heavier than air and will not<br />
disperse or evaporate rapidly if released in still air.<br />
CAUTION: Wear approved protective gloves and eye protection when<br />
working with Chek-Loks ® . Do not vent LP-Gas near possible sources<br />
of ignition.<br />
7590U-20 Application<br />
The 7590U-20 Liquid Evacuation Adapter is for use with RegO ® 7590U and<br />
7591U Chek-Lok ® Actuated Liquid Withdrawal Excess Flow Valves. It is<br />
designed to provide a simple means of evacuating a container equipped<br />
with a RegO ® 7590U and 7591U Chek-Lok ® Valve. The Adapter’s operating<br />
handle opens and closes the equalizing stem in the Chek-Lok ® Valve.<br />
The 7590U-20 Adapter eliminates gas flow through the Chek-Lok ® Valve<br />
during installation or removal of the adapter. This Adapter allows for the<br />
proper connection and opening of the check mechanism.<br />
7590U-20 Features<br />
• Built in nylon gasket provides a gas tight seal.<br />
• Installed without depressing the equalizing stem of the<br />
Chek-Lok ® .<br />
• Eliminates gas flow through Chek-Lok ® Valve during installation or<br />
removal of the Adapter.<br />
• Eliminates need to slug excess flow feature of Chek-Lok ® when removing<br />
the Adapter.<br />
• Built in bleeder valve allows controlled discharge of<br />
liquid before removing the Adapter.<br />
Operation Instructions for the 7590U-20<br />
NOTE: Use of an appropriate 3 /4" shut-off valve with<br />
the 7590U-20 Adapter is recommended. The shut-off<br />
valve should be installed between the outlet of the<br />
Adapter and the unloading hose.<br />
Unloading operations should be performed only by<br />
thoroughly trained and qualified personnel.<br />
Opening 7590U or 7591U Chek-Lok ® with the<br />
7590U-20 Adapter<br />
NOTE: Use a suitable wrench when removing the cap<br />
and Adapter from the Chek-Lok ® . Do not allow the<br />
Chek-Lok ® to un-thread from the tank during removal.<br />
When necessary, use a second wrench to secure the<br />
Chek-Lok ® in position.<br />
1. Loosen the 7590U-5 cap to vent any accumulated<br />
LP-Gas from the Chek-Lok ® . After venting stops,<br />
remove the cap.<br />
If venting does not stop, retighten the cap and use<br />
other approved means to withdraw liquid from the<br />
container.<br />
2. Move the lever of the 7590U-20 Adapter to the<br />
UP & CLOSED position.<br />
3. Completely thread the 7590U-20 Adapter onto the<br />
Chek-Lok ® by turning Adapter’s coupling nut clockwise<br />
with a suitable wrench. Do not over tighten.<br />

CAUTION: DO NOT move lever until instructed. Turning lever will result in<br />
the discharge of liquid propane.<br />
4. Connect an unloading hose to the outlet of the Adapter or to the Adapter<br />
and shut-off valve assembly installed onto Chek-Lok ® Valve.<br />
5. Close the shut-off valve at the tank end of unloading hose. If a shut-off<br />
valve is connected to the outlet of the Adapter, also close this valve.<br />
6. Turn lever to DOWN & OPEN position. This allows flow through Adapter.<br />
WARNING: If the lever does not completely reach the full DOWN & OPEN<br />
position, the equalizing stem may have already been fully opened. Do<br />
not force the lever down further. Forcing the lever will damage the<br />
equalizing stem and seat assembly. This could prevent proper contact<br />
between the seat assembly and the seat when closing the Adapter –<br />
resulting in leaks and the free flow of liquid or vapor through the Adapter.<br />
7. Equalize pressure in the Adapter and Chek-Lok ® . This allows the excess<br />
flow check mechanism in the Chek-Lok ® Valve to open – necessary for<br />
evacuation.<br />
• To equalize pressure when a 3 /4" shut-off valve is connected to the<br />
Outlet of Adapter:<br />
Be sure shut-off valves at adapter outlet and tank are closed. It<br />
should take approximately 20 to 30 seconds to equalize pressure.<br />
After pressure is equalized, slowly open the 3 /4" shut-off valve at the<br />
adapter outlet to pressurize the unloading hose.<br />
• To equalize pressure when a 3 /4" shut-off valve is not connected to the<br />
Outlet of Adapter:<br />
Be sure the shut-off valve at the tank is closed. It may take several<br />
minutes to equalize pressure between the Chek-Lok ® and the<br />
unloading hose.<br />
8. Evacuate the container.<br />
