INSTALLATION INSTRUCTIONSQuick4 Plus Chamber SystemsBefore You BeginThese installation in struc tions are for Quick4 Pluschambers in North Carolina. These chambers may only beinstalled according to state and/or local regulations. Ifunsure of the installation requirements for a site, contactthe local health department.Similar to conventional systems, the soil and siteconditions must be approved prior to installation.Conduct a thorough site evaluation to determine theproper size and location of the system before installation.Materials and Equipment NeededQuick4 Plus ChambersQuick4 Plus EndcapsQuick4 Plus All-in-OneEndcapsPVC Pipe and CouplingsBackhoeLaser, Transit or LevelTape measureShovel and RakeUtility Knife1 1/4-inch Drywall Screws*Screw Gun*Small Valve-cover Box*4-inch Cap Inspection Port* OptionalThese guidelines for construction machinery must befollowed during installation:Avoid direct contact with chambers when using constructionequipment. Chambers require a 12-inch minimum of compactedcover to support a wheel load rating of 16,000 lbs/axle orequivalent to an H-10 AASHTO load rating.Only drive across the trenches when necessary. Never drivewheeled machinery over chambers.Avoid stones larger than 3 inches in diameter in backfill.Remove stones this size or larger that are in contact withchambers.Excavating and Preparing the SiteNote: As is the case with conventional systems, do not install thesystems in wet conditions or in overly moist soils, as this causesmachinery to smear the soil.1. Stake out location of all trenches and lines. Set elevations ofthe tank, pipe, and trench bottom.2. Install sedimentation and erosion control measures.Temporary drainage swales/berms may be installed to protectthe site during rainfall events.3. Excavate and level 36" wide trenches with proper center-tocenterseparation. Verify that trenches are level or have theprescribed slope.Note: Over excavate the trench width in areas where you are planningto contour.4. Rake the bottom and sides if smearing has occurred whileexcavating. Remove any large stones and other debris. Do notuse the bucket teeth to rake the trench bottom.Note: Raking to eliminate smearing is not necessary in sandy soils. Infine textured soils (silts and clays), avoid walking in the trench toprevent compaction and loss of soil structure.5. Verify that each trench is level using a level, transit, or laser.Preparing the End CapNote: Quick4 Plus and Quick4 Plus All-in-One Endcaps are avaliable foruse with the Quick4 Plus chambers on either end of the trench, dependingupon installer’s preference and configuration requirements.1. With a hole saw drill anopening appropriate for pipediameter being used (normally3 - 4 inches) on front or sideof end cap using center pointmarking (see illustrationbelow) as a guide.2. Snap off the molded splashplate located on the bottomfront of the end cap.3. Install splash plate into theappropriate slots below theinlet to prevent trench bottomerosion.1" PRESSURE LATERAL (TYP.)2" PRESSURE LATERAL (TYP.)Installing the Quick4 Plus Inlet AdapterNote: Available for use with Quick4 Plus All-in-One Endcap only.Invert options based on system design.1.
