ACCESSORIES WARRANTY

All single-wall tank accessories and monitoring equipment are warranted to be free from material defects in workmanship and materials for a period of one (1) year following date of original delivery by Containment Solutions.

Containment Solutions� liability under this warranty shall be limited, at our option, to (i) repair of the defective unit, (ii) delivery of a replacement unit to the point of original delivery, or (iii) refund of the original price. CSI shall not be liable for any labor or other installation costs and shall not be liable for any special, indirect, consequential or other damages except as stated above in connection with such tanks, including, without limitation, costs, expenses or liabilities associated with environmental contamination, fires, explosions or any other consequences allegedly attributable to a breach of the warranty or damages under deceptive trade practices or similar consumer protection acts. THE FOREGOING CONSTITUTES OUR EXCLUSIVE OBLIGATION AND CSI MAKES NO EXPRESSED OR IMPLIED WARRANTIES, OR ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE WHATSOEVER, EXCEPT AS STATED ABOVE.

Failure to install the tank accessories or monitoring equipment in accordance with the Containment Solutions� installation instructions will void the warranty.

Fiberglass Tanks Intended Use

Fiberglass petroleum storage tanks are designed for the storage of gasoline, alcohol blended gasoline (with up to 100% methanol or ethanol), jet fuel, av-gas, motor oil, kerosene, diesel fuel, oxygenated fuels (up to 20% MTBE), or potable water at ambient underground temperatures. Fuel oil may be stored at temperatures not to exceed 150�F.

The storage of other liquids may result in tank failure. Before storing liquids other than those listed above, contact Tank Technical Support.

Installation Overview

Fiberglass underground tanks must be installed in accordance with the installation instructions (Containment Solution Pub. No. INST 6001). This document should be part of your tank specifications. Some key installation steps are highlighted below. See the published installation instructions for complete details.

Single-wall tanks must be mechanically unloaded from the delivery truck using a backhoe or crane (using all lift lugs provided to lift the tank).

All tanks must be vented and are intended to be operated with fluid in the tank no higher than the tank top. Fiberglass tanks are designed for operation at atmospheric pressure only, except when using vapor recovery systems, provided the pressure or vacuum does not exceed 1 psi maximum on the primary tank. Overpressurizing of the primary tank will result in tank failure.

For additional details, request Underground Tank Installations (Containment Solution Pub. No. INST 6001). Properly installed, fiberglass underground petroleum storage tanks can provide extended service in storing petroleum products without corrosion-caused leaks and without maintenance.

Containment Solutions maintains a listing of over 2,000 independent contractors who have received educational materials from Containment Solutions covering the proper installation of underground fiberglass tanks. On request, we can provide names of educated contractors.
