Before You Begin
Improper installation may endanger installers and users of this equipment!
Read these instructions CAREFULLY.
1.1
Installer Safety
Installers must be experienced with the requirements of intrinsically safe
devices and must strictly obey the instructions in this manual to perform
a safe installation.
Installation must be in accordance with the U.S. National Electrical Code
(NFPA No. 70) and the Automotive and Marine Service Station Code
(NFPA No. 30A).
For Installations outside of the United States, ensure that the installation
adheres to all applicable local codes.
A fuel tank is a
hazardous area
as defined in the NEC. Only non-
intrinsically safe devices can be installed in or above the Class 1
Division 1 Hazardous area.
1.2
Precision Leak Test
A precision leak test should be performed on each tank—
especially
older ones
—before installing the SiteSentinel® iSite™ Integrated Tank
Monitoring System. This test ensures that leak data generated by the
system is accurate and reliable. A pressurized precision leak test can be
performed on a tank after the probe has been installed, but pressure is
NOT to exceed 5 psi.
Most regulatory agencies will accept the ATG tank test as the
acceptance test on new tank installations.
1.3
Initial Inspection
The console Data Sheet, which can be downloaded from the OPW
Global website at www.opwglobal.com, provides specific details about
your system. Store this sheet in a secure location.
All packaging materials should be inspected thoroughly for damage
that may have occurred during shipping.
1.4
Manifolded Tanks
Tanks can be physically connected or manifolded so that product flows
freely between them. To monitor manifolded tanks with the
SiteSentinel® iSite™ system, each tank in the group must have its own
probe installed and all probes must be connected to the same VSmart
Module.
Many of the procedures described in the following pages must be followed
for each tank that is to be included in the system. Please read all
instructions carefully before proceeding.
