VST Installation Procedure for
Phase II EVR Vacuum Assist
Safety Breakaway Devices
Part Number Series:
VST-HEVR-SBK;
VST-ISVR-SBK
APPLICATION
These VST Safety Breakaway devices are intended to prevent damage to the
dispenser and hose in the event of a vehicle drive off. These devices separate
at pull forces up to 350 lbs. You will need to determine that 350 lbs. of pull
force will not damage the dispenser.
After verifying that the dispenser is securely bolted to the island, it can be
tested by using a spring scale and a length of rope. The rope must be connected
at the dispenser outlet casting, which may require a threaded bushing with a
hole for attaching the rope. Attach the scale to the rope and pull to 350 lbs.in
several directions. Be sure to avoid damaging the dispenser.
NOTE
a. The whip hose ALWAYS attaches to the dispenser. If a retractor is
being used, the retractor clamp MUST be between the breakaway and
dispenser.
b. VST hoses are made to withstand 350 pounds tensile pull without damage.
If another brand of hose is present at the dispenser, VST recommends that
you contact the hose manufacturer regarding the compatibility with this
breakaway device.

GENERAL INFORMATION

If hanging hardware components are involved in a drive-off or incur other
customer abuse, each individual component must be functionally tested prior
to customer dispensing activities.

INSTALLATION PREPARATION

These procedures must be followed to ensure leak-proof installation and
operation of these safety breakaway products.
1. Turn off and tag the power to the dispenser. Dispenser must be de-energized
prior to service to avoid personal injury.
2. Barricade work area to block vehicle access to the dispenser.
3. Close dispenser shear valve prior to performing any service work with the
hanging hardware (hoses, safety breakaways, and nozzles).
4. Drain liquid product from the hanging hardware set into an approved
container prior to replacing any hanging hardware component.
5. When not using the VST Breakaway Assembly Tool (VST-BAT-200), remove
hanging hardware from the dispenser prior to making replacement
component assembly connections. VST recommends connecting the
whip hose to dispenser as the last connection during hanging hardware
assembly.
INSTALLATION AND FUNCTION TESTS
1. Initial inspection:
a. Carefully unpack safety breakaway from shipping carton.
b. Inspect safety breakaway for any damage to threads, O-rings, exterior, etc.
2. Lightly lubricate ALL O-rings on mating connections with petroleum jelly or
other suitable lubricant. DO NOT USE pipe dope or thread sealant.
