<br />It is important to follow the procedures and instructions in this
<br />manual in order to safely and properly install a Xerxes
<br />Underground Storage Tank. Failure to follow these instructions
<br />will void the tank warranty and may cause tank failure, serious
<br />personal injury, or property damage. The Xerxes warranty applies
<br />to a tank installed according to these instructions. Since Xerxes
<br />does not control the parameters of any installation, our sole
<br />responsibility in any installation is that presented in our warranty.
<br />Use the Tank Installation Checklist for all Single Wall Tanks (SWT),
<br />Double Wall Tanks (DWT), Oil Water Separator (OWS) and Multi
<br />CompartmentTanks (MCT) found inserted in this manual, as the
<br />installation proceeds. Retain a copy of the checklist, along with any
<br />deviation—authorization letters, certification etc. in your files and any
<br />other project files. Consult your Xerxes representative or distributor
<br />for a supply of additional checklist fors.
<br />Comply with all applicable regulations and standards, such as:
<br />• national, state and local construction, health, safety and
<br />environmental codes
<br />• National Fire Protection Association standards (e.g. NFPA
<br />30, 30A & 31)
<br />• industry standard practices (e.g. PEI/RP100, API RP1615 &
<br />EPA "Doing It Right")
<br />For additional information, contact your state, county and city
<br />storage tank authorities, including health, fire or building depart-
<br />ments, and environmental agencies. All work must be performed
<br />according to standard industry practices and OSHA regulations.
<br />A Xerxes requirement will never take precedence over a
<br />requirement imposed by any federal, state or local code or
<br />regulation. In all cases, any such requirement takes precedence
<br />over any provision of the Xerxes manual.
<br />Xerxes must authorize any variation to, or deviation from, these
<br />instructions. This authorization must be made in writing, prior to
<br />the tank installation.
<br />DEFINITIONS: Throughout this text, these definitions will apply:
<br />• Service fitting: a fitting, either on a manway or on the tank
<br />shell, which opens into the primary containment vessel,
<br />where the tank's contents are normally stored;
<br />• Monitor fitting: a fitting, located on the tank shell, which
<br />opens into the secondary containment vessel, which is the
<br />normal monitoring location on the tank.
<br />For additional terminology, see Figure 0-1.

<br />Before beginning the tank installation, read through the entire
<br />installation manual. It is the installer's responsibility to comply
<br />with all safety precautions, codes and regulations. No instructions
<br />or procedures presented in this manual should be interpreted as
<br />to put at risk any person's health or safety or to harm any
<br />property or the environment. Keep the Installation Manual
<br />available at the installation to refer back to safety procedures as
<br />needed. The following definitions will serve as a guide when
<br />reading the Installation Manual:
<br />Q DANGER:
<br />Indicates immediate hazards which, if not avoided, will cause
<br />death, serious personal injury or significant property damage.
<br />Q WARNING:
<br />indicates hazards which, if not avoided, could cause death,
<br />serious personal injury or significant property damage.
<br />tQ- CAUTION:
<br />indicates hazards which, if not avoided, may cause personal
<br />injury or property damage.
<br />Working in excavations is dangerous and is regulated by both
<br />federal and state safety codes. Careless activity or operation of
<br />equipment can cause severe personal injury or death.
<br />Although the corrosion -resistant Xerxes tanks are rugged, care
<br />must be taken that they are not dropped or damaged during
<br />delivery, unloading and handling on the job site.
<br />L WARNING:
<br />The tanks are heavy and have a large surface area. The tanks
<br />will roll on sloped surfaces and can be blown about by the
<br />wind. Uncontrolled movement of the tanks can cause death,
<br />serious personal Injury and property damage.
<br />Before the tanks are unloaded or relocated on the job site:
<br />• be sure that all equipment used to lift the tanks is rated to
<br />handle the load (Refer to the installation supplement "Tank
<br />Handling Data" for tank weight),
<br />• prepare the unloading and/or storage site by removing all
<br />rocks and debris,
<br />• arrange for sandbags or tires to be used as chocks.
<br />Use the lifting lug(s) when hoisting the tank. Do not wrap chain or
<br />cable around the tank. Tanks larger than 12,000 gallons have
<br />multiple lifting lugs. Use all of the lugs to move the tank. (See Fig.
<br />1.1). Use guy ropes to guide the tank when needed. Do not move
<br />the tank by rolling.
