- Page 2 Installation procedures, equipment and personnel should always comply with applicable safety regulations as well as all federal, state and local codes. The Hydro-Kinetic system must be installed by an authorized representative of Norweco according to these instructions to insure safe, reliable and efficient operation. Carefully unpack and inspect the system components.
- Page 3 Bio-Film Reactor outlet tees if these components have not been cast in place. Norweco recommends assembling all of these components, as well as the Bio-Film Reactor elements, before the tanks are delivered to the installation site. Install components according to the following steps: For a one-piece tank, solvent weld the 4"...
- Page 4 Prepare the excavation to the appropriate depth based on the elevation of the building sewer line. Concrete systems should have a maximum burial depth of 42" below grade to top of the tank. HDPE systems should have a maximum burial depth of 36½" below grade to top of the tank. Allow ⅛" of fall per foot from the building to the system. Fall through the system is 5"...
- Page 5 Inspect the power cable entrance in the side of the clarification riser. Remove any sharp edges or flash. Insert the free end of the power cable through the shorter segment of a pre-formed ½" conduit ell (2' by 1'), then into the power cable entrance of the clarification riser.
- Page 6 Install the smaller diffuser and drop pipe assembly into first aeration chamber by bending the flexible tubing. Lower assembly into the tank until the diffuser bar contacts both the floor and side wall of the tank as shown in Figure 4. Install the longer diffuser and drop pipe assembly into second aeration chamber by bending the flexible tubing.

pump rests on the floor of the hopper as shown in Figure 7. Attach subassembly subassembly S6 at the union. Securely tighten the union by hand. In the anoxic chambers: Attach subassembly ANOXIC CHAMBER subassembly S8 at union as shown CLARIFICATION in Figure 7. - Page 8 location should minimize exposure to direct sunlight, freezing rain or conditions that might prevent routine inspection or access. The control center should always be mounted out of the reach of children. Remove the cover from the alarm wire junction box connected to the float switch. Solvent weld the junction box to the conduit containing the alarm leads, located in the second aeration chamber riser.

The system is operational once all installation and startup steps have been completed to this point. It will take 2 to 6 weeks for the system to reach biological maturity, depending upon system loading. Routine Maintenance The following should be performed every 12 months (or as required by your local governing regulations) by a qualified service technician: If applicable, inspect the effluent discharge point to make sure there are no restrictions to the effluent flow. -

percentage of settled solids volume (i.e. ½ full of solids equals 50%). If the settled material contains large pockets of clear liquid, estimate the volume of these pockets and reduce the settled solids reading by that amount. A settled solids reading of up to 80% indicates no adjustments are necessary. A settled solids level greater than 80% in the aeration chamber indicates excessive solids and that the system should be pumped. - Page 12 Air pump is running but does not pump air: clean or replace air filter. Internal components are worn and the air pump is failing. Rebuild or replace the air pump. Contact the authorized Norweco representative for replacement components.

- Page 13 Proper sampling techniques are important to ensure that the results are representative of system performance. To ensure an accurate sample is collected, Norweco recommends that a sample port be installed immediately downstream of the treatment system. The sample port should allow a free falling sample to be collected. Sample ports should be cleaned before attempting to collect a sample.
