To Prevent Fire or Explosion Hazard AWARNING Owens-Corning Recommends Air Driven Tools Whenever Possible. Do Not Use Electric Power Tools Where Flammable Vapors or Liquids Exist. Also, When Electric Hand Tools Are Used, Be Aware of Potential Shock Hazards. Wear Protective Clothing and Eye Protection. F1 -A. General —Secondary Containment Collar Intended use of this collar: • Termination point for secondary piping systems. • Must be continuously monitored for piping leaks using an electronic sensor. The secondary containment collar provides: • Containment of spilled liquids from a submersible pump. • Location for the leak monitoring sensor. F1 -B. General — Turbine Enclosure Intended use of turbine enclosure: • Separate turbine from corrosive coils. • Prevent ingress of groundwater when properly sealed, not the exit of fuels. The turbine enclosure provides: • Housing for a submersible pump. • Termination point for double-wall piping systems. If there is concern regarding the ingress of water: • Use optional adhesive kit to cement the secondary contain- ment collar (which is factory installed to the tank top). After completing all piping and wiring connections: • Place polyethylene top and lid over turbine enclosure. ❑ Polyethylene top is designed to prevent water run-off from entering turbine enclosure. Ll If groundwater rises to the polyethylene top, water will infiltrate turbine enclosure. For high groundwater conditions at or above subgrade: • Use sealable turbine enclosure to prevent water infiltration. F2. Handling • Wear gloves to manually lift the turbine enclosure. • Do not roll or drop. • Set on smooth ground. 20 Important: If high winds are anticipated, the contractor is responsible for tying down the turbine enclosure to prevent damage from being moved by high winds. F3. Inspection Before installation: • Visually inspect the turbine enclosure for potential shipping damage. • If damage is found, contact the Owens -Coming Field Service office nearest you. Phone numbers are listed on page 2. F4. Tank Burial Depth Before installing the turbine enclosure: • Measure length to be sure it is long enough. ❑ Turbine enclosures are available in lengths of one foot increments from 2' to 5' to accommodate deeper burial depths. If turbine enclosure is too long: • It can be trimmed to length before or after it is installed on collar. ❑ Carbide tipped blade or masonry blade is recommended. If cut to length at jobsite: • Cut upper portion of turbine enclosure. ❑ Cut lines are marked in 3" increments. If bottom portion of the turbine enclosure is trimmed: • Must be evenly cut within ± 1/4". ❑ Carbide tipped blade or masonry blade is recommended. To adjust the sealable turbine enclosure for final burial depth: • See section F11 for details. F5. Mounting Turbine Enclosure To Collar Prior to mounting turbine enclosure to collar: • Rotate the manway cover to align tank fittings and submersible pump with intended piping layout. • If manway cover is removed: ❑ Inspect manway gasket for damage. ❑ Replace if necessary. To prevent ingress of water: • Cement turbine enclosure using optional adhesive kit (kit AD) supplied by Owens-Corning. ❑ Joint is not designed as product tight.
