D2. TURBINE ENCLOSURE HEIGHT -continued If turbine enclosure is too long: ♦ Trim length before installation on the collar. ❑ Carbide tipped blade or masonry blade is recom- mended. ❑ Cut lines are marked in 3" increments. ❑ Must be square cut within ±%" in order for adhesive kit to properly seal the joint. D3. TOP CLEARANCES Important: Isolate All Turbine Enclosure From Direct Traffic Loading (Applicable to Non -Sealed, Watertight and Sealed Turbine Enclosures) Typical Installation Plywood (48"x48"x314") Street Box NTE Friction Fit Lid * Reinforced Concrete 7F7 er nt * #5 Rebar 8" o.c., both ways, extending 4'0" in all directions from center er backtillinq to top of turnine enclosure: ♦ Place 1-114" of specified gravel and then 314" thick ply- wood (4'x 4') over turbine enclosure top (but not over fid) to allow 2" minimum clearance between top of turbine enclosure and bottom of concrete surface pad (see fig- ure 27). • This 2" clearance also provides a channel for water runoff. If the tank is located in a traffic area: ♦ Pour traffic slab directly onto plywood. ❑ Reinforce with #5 rebar 8" on center both ways ex- tending 4' in all directions from street box. ♦ After turbine enclosure is installed: ❑ Use a minimum 36" diameter (or 36" square) street box to allow lid removal after installation. 20 D4. MOUNTING TURBINE ENCLOSURE TO COLLAR Priorto mounting turbine enclosure to collar: ♦ Rotate the manway cover to align tank fittings and sub- mersible pump with intended piping layout. If manway cover is removed: ❑ Inspect manway gasket for damage. ❑ Replace gasket if necessary. To prevent ingress of water: ♦ Cement turbine enclosure to collar using optional adhe- sive kit (Kit AD) supplied by Containment Solutions.

Step 2 Sand bottom 3" of the turbine enclosure interior surface using supplied sandpaper Step 3 Sand inside surface of the adhesive channel on the sec- ondary containment collar. NOTE: All surfaces must be sanded until they are clean and appear "white" in color. Step 4 Wipe the mating surfaces clean. Position Turbine Enclosure on Collar (see figure 28) Step 1 Use a rubber mallet, if necessary, to seat turbine enclosure on collar. Step 2 Confirm that surfaces inside adhesive channel are dry and clean before mixing or applying the adhesive. NOTE: As an option, you may apply tape to the exterior of the joint to minimize adhesive run on the exterior of the turbine enclosure.
