SA ETY PRECAUTIONS – INSTALLATION AND MAINTENANCE
Using electrically operated equipment near gasoline or gasoline vapor may result in fire or explosion causing
serious personal injury and/or property damage. ALWAYS disconnect and lock power supply before testing or
servicing the Yenen shut-off valve.
The following instructions are provided to guide you in properly installing and maintaining your Yenen shut-off
valve. Failure to follow these instructions may cause failure of the valve to close in the event of an
emergency, resulting in a hazardous condition. Make sure that all necessary safety precautions have been
taken during installation and maintenance.
The valve body must be firmly anchored to a structural part within the island to ensure breakage at
the shear groove in the event of severe impact. Failure to ascertain a rigid mounting may result in failure of
the valve to close in the event of a severe impact, resulting in excessive loss of product and a hazardous
condition.
The shear groove must be positioned at the same level as the dispenser mounting frame. Failure to install the
shear groove at this level may result in a failure to break-off in the event of severe impact, causing a
hazardous condition.

Attaching valve to riser pipe
1- The riser pipe threads should be coated with a non-hardening, gasoline resistant pipe compound.
Do not use Teflon tape.
2- Thread the valve tightly on the riser pipe wrenching on the main valve body only. Do not wrench
above the shear section as this can result in valve breakage.
3- Maximum torque on pipe threads: 16 kgm.
Attaching outlet valve to fuel dispenser
1- The connecting pipe threads should be coated with a non-hardening, gasoline resistant pipe compound.
Do not use Teflon tape.
2- Hold the valve steady with a wrench on the hex head of the valve. Use a second wrench to tighten the
connection.
3- Maximum torque on pipe threads: 16 kgm.
Manual valve operation
To open the valve, rotate the latch counter-clockwise and hook the latch into the notch on the soldered wind
arm.
To close the valve, unhook the latch from the soldered wind arm, allow the latch to rotate clockwise until it
stops.
Disconnect power to the fuel pump before testing or servicing valves. DO NOT OPEN WHEN P P NG
SYSTEM S UNDER PRESSURE.
Required maintenance
To ensure that the valve is operating freely, it should be manually opened and closed several times, then
reset, at least once a year.
Pressure testing the piping system
This testing is only for the piping system. The tank should be isolated and not subjected to the pressure
used in testing the piping system.
Yenen shut-off valves have a built in 3/8” NPT test plug to permit testing of the piping system for leaks after
installation. Before starting the test, make sure that the pump is turned off. Then manually close all shut-off
valves connected to the same product line, remove the test plug. Attach the gauge and pressurize. t is not
necessary to break any other connections. Maximum recommended test pressure is 4 bars and recommended
test duration is 30 minutes. Local regulations or specifications supersede these recommendations. When
reinstalling the test plug, coat the threads with a non-hardening gasoline resistant pipe compound.
