INSTALLATION AND OPERATION MANUAL

Hydro-Kinetic®Installation and Operation Instructions
Wastewater enters the pretreatment chamber to precondition the waste before it flows into the anoxic chamber.
Once in the anoxic chamber, facultative anaerobes digest organic matter. Flow then enters the aeration chamber
where aerobic bacteria biologically convert the waste into stable substances and oxidize ammonia into nitrite and
nitrate. Following aeration, liquids flow to the clarification chamber where gravity settles out biologically active
material. A recirculation pump in the clarier transfers a portion of the wastewater back to the anoxic chamber where
nitrogen compounds are converted to harmless nitrogen gas. From the clarier, treated liquids pass through the ow
equalization device and into the disposal system. E󰀪uent passes through the Bio-Film Reactor for nal treatment.
The Hydro-Kinetic system is certied to BNQ Standard 3680-600 Class B-IV, D-I, N-I and BNQ Standard 3680-910 Class III,
averaging e󰀪uent quality of 3.0 mg/L CBOD, 2.0 mg/L TSS, 67% Nitrogen removal and 2,200 CFU/100 ml fecal coliform.

Pre-Delivery Tank Preparation
The Hydro-Kinetic tank equipment package contains some components that are cast-in the tank during the manufacturing
process, and other components that are installed after the casting process is complete. In the standard two-piece tank, the
only component that needs to be installed prior to delivery is the intermediate recirculation assembly. In a one-piece tank,
the distributor will need to provide a pretreatment outlet tee, an aeration chamber inlet elbow and a Bio-Film Reactor outlet
tee. Norweco recommends assembling all of these components, as well as the Bio-Film Reactor elements, before the tank
is delivered to the installation site. Install components according to the following steps:
1. For a one-piece tank, solvent weld the 4" Schedule 40 PVC pretreatment outlet tee to the coupling that was cast-in the
outlet of the pretreatment chamber (distributor to provide). Solvent weld the 4" Schedule 40 PVC aeration chamber
transfer elbow into the coupling cast-in the inlet of the aeration chamber (distributor to provide).
2. For all systems, begin in the anoxic chamber and solvent weld subassembly S1 into the coupling that was cast-in the
wall between the anoxic and aeration chambers. The elbow should be oriented as shown in Figure 2, with the short
stub of pipe parallel to the oor and ceiling of the tank.
3. Solvent weld subassembly S2 into the aeration chamber side of the same cast-in coupling. See Figure 2.
4. Starting in the aeration chamber, pass subassembly S3 through the wall into the clarication chamber. Solvent weld
the coupling on subassembly S2 to subassembly S3. See Figure 2.
5. Place the Bio-Film Reactor elements into the media chamber of the Bio-Film Reactor tank. They will rest on the
support rib cast into the media chamber. The Bio-Film Reactor elements should be installed with the media service
hatch oriented toward the middle of the tank and facing up. See Figure 3.
6. Using the universal tool, rotate the two slide locks on each Bio-Film Reactor element so that they lock into the recesses
cast into the tank.
Tank Delivery and Setting
1. When installing a Hydro-Kinetic system, rst check the length, width and depth of the excavation. Insure the excavation
is long enough to allow at least 2' between the treatment tank and the Bio-Film Reactor for installation of the interconnect
plumbing and backll between the tanks. Cut a 4" Schedule 40 PVC pipe (distributor to provide) 6" longer than the
distance between the tanks for the interconnect plumbing. Insert the interconnect pipe into the inlet of the Bio-Film
Reactor tank prior to tank placement. This allows the interconnect pipe to be backed straight out, and solvent welded
into the cast-in outlet coupling of the clarication chamber when the tank is set. The excavation should have su󰀩cient
overdig to allow for a minimum of 6" clearance around the entire perimeter of the system. Additional overdig will be
required on deep installations or where unstable soil conditions exist. Safe working conditions must be established
and maintained during the entire installation procedure.
2. 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" from inlet invert to outlet invert. Therefore, the outlet line from the system must be installed
5" lower than the inlet sewer line. The bottom of the excavation must be level and smooth. A 4" layer of gravel, sand
or ne crushed stone should be installed and leveled to within ¼" from side to side and end to end.

3. Using extreme caution, place the treatment tank into the excavation. Place the Bio-Film Reactor in the excavation
allowing at least 2' between the treatment tank and the Bio-Film Reactor tank. Insure tanks are installed square and
level.
4. Connect the building sewer line to the pretreatment chamber inlet. The inlet line must be laid continuously and
unspliced from the tank to undisturbed earth beyond the limits of the tank excavation.
5. Back the interconnect pipe out of the Bio-Film Reactor tank and solvent weld the pipe to the outlet coupling of the
clarication chamber. Then, connect the discharge sewer line to the Bio-Film Reactor tank outlet continuously and
unspliced from the tank to undisturbed earth beyond the limits of the tank excavation. If using a one-piece tank, insert
discharge sewer line through tank outlet seal, leaving 4" to 6" protruding inside the tank. Solvent weld the 4" Schedule
40 PVC outlet tee (distributor to provide) to the discharge sewer line.
6. Install risers as required to bring the access covers to grade.
Plant Wiring and Control Center Installation
1. Electrical work must be performed in accordance with the latest edition of the National Electrical Code as well as
applicable local codes.
2. All electrical service cable used with the Hydro-Kinetic system must be UL and CSA approved, type UF, #14/2 AWG
minimum and must have a full-size center ground. Larger cable is required if the length of the underground service is
greater than 80 feet. Consult your electrician for details.
3. An approved cable must be installed from the air pump to the junction box provided for connection to the control
center. If installing the air pump in a location other than the aeration chamber riser, insure the air line is no more
than 75' in length and the air pump is protected from the elements in a clean, dry, well-ventilated area and proceed
to step 6.
4. Inspect the power cable entrance in the side of the aeration riser. Remove any sharp edges or ash. 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 aeration riser. Guide the power cable into the riser. Pull enough cable through the riser to reach 36"
above the riser top. Coil and secure the cable in the aeration riser so that it will not hang down into the tank.
5. Lay the conduit ell with cable directly across the top and down the tank side. Do not allow the power cable to be laid
across the end of the tank or any removable access cover. Seal the connection between the conduit and the aeration
riser with mortar or approved sealant.
6. A second underground cable must be installed unspliced from the Service Pro control center into the clarication
chamber riser to supply power to the recirculation pump.
7. Inspect the power cable entrance in the side of the concrete clarication riser. Remove any sharp edges or ash.
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 clarication riser. Guide the power cable into the riser. Pull enough cable through the
riser to reach 36" above the riser top. Coil and secure the cable in the clarication riser so that it will not hang down
into the tank.
8. Lay the conduit ell with cable directly across the top and down the tank side. Do not allow the power cable to be
laid across the end of the tank or any removable access cover. Seal the connection between the conduit and the
clarication riser with mortar or approved sealant.
9. Two alarm leads must be installed from the air pump pressure switch to the Service Pro control center. The alarm
leads should be #16 AWG minimum and installed in conduit where contact with concrete may occur. IMPORTANT:
Alarm leads and power leads must always be installed in separate conduits.
10. Two alarm leads must be installed from the high water oat switch to the Service Pro control center. The alarm leads
should be #16 AWG minimum and installed in conduit where contact with concrete may occur. IMPORTANT: Alarm
leads and power leads must always be installed in separate conduits. If the air pump will be installed in the aeration
riser, the high water and air pump alarm leads should be installed in the same conduit. Properly seal the conduit
opening in the riser with mortar or approved sealant.
11. Check the excavation and sewer line trenches to be sure they are free of debris, rocks and any sharp or abrasive
objects that could damage electrical cables or alarm leads during backll or settling.

Page 4
12. Uncoil the electrical service cables and alarm leads into the excavation and inuent sewer line trench. Leave su󰀩cient
slack in the cables so they will not be stressed or pulled tight during backll or settling.
13. Always encase the electrical cables and alarm leads in conduit any time they are above nished grade. Route the
conduits and cables as directly as possible to the control center mounting location.
Required Prior to Backlling
1. For installations where the air pump will not be located in the aeration riser, install a ¾" Schedule 40 PVC air line from
the air pump to the system. The air line should be buried in a trench at a recommended depth of at least 12 inches.
Protect the air line in a casing pipe if heavy loading is anticipated. The air line must be run into the aeration riser and
the opening in the riser sealed with mortar or approved sealant.
2. On the Bio-Film Reactor elements, use the universal tool to insure each of the slide locks are rotated until they are in
the furthest extension point possible.
Backlling
1. The system should be backlled immediately after sewer lines and underground electrical cables are installed. Fine,
loose earth should be used to backll the tank excavation and sewer line trenches. Be sure it is completely free of
rocks, large clumps of earth and construction debris. Use ne granular material when backlling around electrical
cables and conduits. The underground electrical cables should have at least two feet of earth cover. If the proposed
nished grade will not permit this coverage, the cables should be installed in approved conduit from the tank to the
building foundation. Backll evenly around the entire perimeter of the tank rather than all at once on each side. Take
care to completely ll in the cavity beneath the hopper at the bottom of the clarier end wall.
2. Final grading should be 6" below the top of each access cover and should slope away from the tank so surface runo󰀨
will drain away from the treatment system. Use extreme care in backlling. Do not allow dirt or mud to enter any part
of the treatment system or sewer lines. If dirt or mud enters any portion of the system, it must be removed to insure
proper system operation. Removing the dirt or mud may require repeated ushing and tank pumping.
3. Immediately after backlling, ll each chamber of the
treatment system with water to the outlet invert. The
water must be free of leaves, mud, grit or any other
materials that might interfere with system operation.

side wall of the tank as shown in Figure 4.
5. Remove air pump and components from carton. If
the air pump will be installed in the aeration chamber
riser, install a concrete support base for air pump.
6. Install the air pump in the aeration chamber riser on
the support base (or in a clean, dry, well-ventilated
area protected from the elements no more than
75' from the tank). Attach subassembly A4 to
subassembly A5 at union as shown in Figure 4.
Securely tighten union by hand.

Figure 8. Use the universal tool to insure the device is completely seated in the ange.
Completing the Installation
1. The control center should be wired for operation when the tank and underground electrical cables are installed. The
control center should be located so that the red warning light can be seen and the audible alarm heard. The mounting
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.
2. Remove the cover from the alarm wire junction box connected to the oat switch. Solvent weld the junction box to the
conduit containing the alarm leads, located in the aeration chamber riser.
3. Reference Figure 9 for all wiring instructions. The black and white alarm wires contained in the junction box are
provided to connect the oat switch to the control center. Connect the black wire in the junction box to either alarm

Final Check and System Startup
1. Place the dedicated circuit breaker for the Hydro-Kinetic system in the main service panel in the "on" position.
2. To commission the telemetry system, rst insure the phone/network cable is properly installed. Place the control
center power switch in the "o󰀨" position. While holding in the reset button, place the power switch in the "on" position.
Continue to hold the reset button for 5 seconds. Release the reset button and allow the telemetry system up to 60
seconds to call out and complete the commissioning process. The phone/network light will illuminate during the
call out process. If commissioning is successful, the alarm light will ash 5 short ashes and stop as verication. If
commissioning is unsuccessful, refer to the Service Pro Model 801P Installation and Operation Instructions.
3. If no telemetry system is installed, press and hold the RESET button on the control center for 5 seconds. The audible
alarm should sound and the alarm light should illuminate.
4. 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. DANGER: Make sure the system
access covers are in good condition and securely installed on the mounting castings. Never allow access
risers to be left uncovered or partially covered. Failure to secure access covers and safety nets could result
in bodily injury, illness or death. Riser safety nets are available from Norweco for concrete or plastic risers.
Routine Maintenance
The following should be performed every 12 months (or as required by your local governing regulations) by a qualied
service technician:
1. If applicable, inspect the e󰀪uent discharge point to make sure there are no restrictions to the e󰀪uent ow. If restrictions
are present, perform service as needed.
2. If e󰀪uent sampling is required, it is recommended that a proper sampling port be installed downstream of the system.
3. Inspect the vent cap, perimeter vent and air pump for objects, plants, insects or debris that could impede the air intake.
Remove these items if present.
4. Check the air pump for proper operation. Check the air lter and clean or replace as required. Check the aeration
chamber for odor. A musty odor indicates the presence of aerobic conditions essential for proper treatment. A septic
odor indicates inadequate aeration, suggesting that the delivery of air into the aeration chamber has been restricted.
5. Check the aeration chamber and insure the di󰀨user assembly is creating a rolling motion of the chamber contents. If
a rolling motion is not visible, verify air pump operation. Remove and clean di󰀨user assembly if necessary.
6. Check the anoxic chamber and insure the mixing bar is operational. The recirculation pump operates on a
pre-programmed on/o󰀨 cycle, so press the reset button if necessary to verify operation.
7. Inspect the ow equalization device. Rinse the design ow, sustained ow and peak ow ports with a garden hose and
insure they are free of debris. Clean the ow ports with a brush if necessary.
8. Use the hopper scraping tool to gently scrape all surfaces of the clarication chamber hopper.
9. The settled solids should be pumped from the Bio-Film Reactor tank to the pretreatment chamber. With the ow
equalization device securely in place, install the outlet blocking tool into the clarier outlet coupling prior to pumping.
Place the intake of the service pump at the bottom of the inuent chamber. Pump the contents from the bottom of
the Bio-Film Reactor tank until the accumulated solids are withdrawn and the water level is below the bottom of the
Bio-Film Reactor elements. Approximately 150 gallons will be removed during service. Rinse the media with a hose
during tank pumping. After pumping, remove the outlet blocking tool and allow the Bio-Film Reactor tank to rell to
normal operating level. Never leave the Bio-Film Reactor tank empty after pumping.

Page 9
10. Inspect the system to determine if complete pumping may be required. See "System Pumping" section of this document.
11. Upon completion of the inspection, insure that all access covers are properly reinstalled. Any missing or damaged
access covers should be immediately replaced. DANGER: Make sure the system access covers are in good
condition and securely installed on the mounting castings. Never allow access risers to be left uncovered
or partially covered. Failure to secure access covers and safety nets could result in bodily injury, illness or
death. Riser safety nets are available from Norweco for concrete or plastic risers.
12. Approved replacement parts are available from the authorized system dealer listed on the control center cover.
System Pumping
1. The Hydro-Kinetic system is a biological treatment device and will not require pumping as often as a septic tank.
Pumping of the system will likely be required at 3 to 5 year intervals depending upon system usage, loading and
treatment requirements. If pumping is required more frequently than every 2 years, there is an operational problem
with the system and it should be evaluated in greater detail.
2. If the service technician suspects that the system may require pumping, a settleable solids test should be performed on a
sample from the aeration chamber. The air pump must be removed from the aeration chamber riser to perform this test.
3. Immediately after removing air pump, dip a graduated cone or other clear container into the aeration chamber to a
depth of 2½ feet. Set the container on a level surface and then allow the solids to settle for 30 minutes while you
complete the service inspection. Do not disturb the container during the test.
4. After 30 minutes, read the level of solids and compare it with the total liquid volume in the container. Calculate the
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.
5. If it is determined that pumping is required, contact a tank pumping service licensed by the local regulatory agency.
The septage or biosolids from the system must be removed and disposed of in a manner consistent with federal, state
and local regulations. Advise the pumping service that they will be pumping approximately 1,500 gallons.
6. Turn o󰀨 the air pump and recirculation pump before tank pumping.
7. Remove the access cover from the aeration and clarication chambers. Unplug the air pump and disassemble the
union located on the primary air connection. Remove the air pump, primary air connection and support base from
the aeration riser. Use the universal tool to bend exible di󰀨user tubing and remove the di󰀨user drop pipe assembly.
Connect the suction hose to the pump being used to evacuate the chamber.
8. Activate the pump and remove the aeration chamber contents. Pump the aeration chamber from the top down, to remove
biologically inactive material. Feed the hose down as the liquid is being evacuated from the aeration chamber. It is not
necessary to wash down the sidewalls or tank bottom. Pump only 75% of the volume out of the aeration chamber to
facilitate plant re-start. Replace the di󰀨user drop pipe assembly. Reinstall the support base, primary air connection and
air pump. Reassemble the union in the primary air connection and plug in the air pump. Replace both access covers.
9. The Bio-Film Reactor tank should be pumped after the aeration chamber. Remove the Bio-Film Reactor tank
access cover. Lower the hose into the inuent chamber until it contacts the bottom of the tank. Withdraw the hose
approximately 2 inches. Completely pump 100% of the contents from the chamber and rinse the media with a hose
during tank pumping. Replace the Bio-Film Reactor tank access cover.
10. Next, pump the anoxic chamber. Remove the anoxic chamber access cover. Use the universal tool to bend exible
mixing bar tubing and remove the mixing bar drop pipe to allow access for the suction hose. Lower the hose until it
contacts the bottom of the tank. Withdraw the hose approximately 2 inches. Completely pump 100% of the contents
from the chamber. Reinstall the mixing bar drop pipe assembly and replace the access cover.
11. The nal chamber to pump is the pretreatment chamber. Remove the pretreatment chamber access cover. Break
up the scum mat to facilitate pumping. Lower the hose until it contacts the bottom of the tank. Withdraw the hose
approximately 2 inches. Activate the pump and remove 100% of the chamber contents. It is not necessary to wash
down the sidewalls or tank bottom. If solids are so concentrated that the suction hose cannot withdraw them, tank
contents may be backushed to break up the solid matter. Replace the pretreatment chamber access cover.
12. After pumping, rell all chambers to capacity with clean water. Return all plumbing and equipment to its properly
installed location. Replace any access covers that were removed. Turn on power to the air pump and the recirculation

pump. Check for proper operation of all equipment. DANGER: Make sure the system access covers are in good
condition and securely installed on the mounting castings. Never allow access risers to be left uncovered
or partially covered. Failure to secure access covers and safety nets could result in bodily injury, illness or
death. Riser safety nets are available from Norweco for concrete or plastic risers.
Troubleshooting
This troubleshooting section provides solutions to the most common problems encountered in the operation of the system.
Control Center Alarming
1. Liquid in tank at level of high water alarm oat: system is ooded due to an obstruction in the ow
equalization device, outlet, e󰀪uent line or disposal eld. Determine cause and remove obstruction, or make
repairs as required. Be sure to check e󰀪uent disposal system for proper operation.
2. No rolling action in aeration chamber:
•Air pump is pumping air but there is an obstruction in the line between the air pump and di󰀨user: disassemble
air line and remove obstruction.
• Di󰀨user is plugged: remove and clean di󰀨user.
• Air pump is not running: check power supply to air pump.
• Air is escaping through a leak in the plumbing assembly between air pump and di󰀨user: identify and repair
air leak. If necessary, remove the di󰀨user, di󰀨user drop pipe assembly, and primary air assembly from the
aeration chamber and use a soapy water solution to thoroughly coat the plumbing and check for bubbles.
Repair any leaking air pipe or tting and retest.
3. Air pump is running but does not pump air: clean or replace air lter. Internal components are worn and
the air pump is failing. Rebuild or replace the air pump. Contact the authorized Norweco representative for
replacement components.
4. No mixing action in anoxic chamber:
• Recirculation pump is operating but there is an obstruction in the line between the recirculation pump and
mixing bar: disassemble mixing bar plumbing and remove obstruction.
• Recirculation pump is not operating. Pump needs replaced. Contact the authorized Norweco representative
for replacement components.
• Mixing bar is plugged: remove and clean mixing bar.
• Check valve is stuck in closed position: repair or replace check valve.
Septic Odor from System
1. No power to air pump: check air pump for proper operation. Insure the breaker is in the "on" position, the air
pump is plugged in and power is present (check with test light from Tool Kaddy)
2. Insu󰀩cient air delivery to aeration chamber: see “Control Center Alarming”
3. Incomplete treatment due to hydraulic overloading: see “Hydraulic Overloading of System”
4. Water softener backwash discharging into system: notify owner to remove backwash line from system
5. Excessive solids in aeration chamber: evaluate chamber and pump if necessary
6. Excessive solids in anoxic chamber: evaluate chamber and pump if necessary
Hydraulic Overloading of System
1. Ground water entering tank through defective inlet or outlet seal: excavate and repair seal
2. Ground water entering system through crack in tank: excavate and repair crack with hydraulic cement
3. Ground water entering system through joint between riser and tank: excavate and reseal joint with
non-shrink grout or mastic
4. Roong down spouts, footer drains or oor drains tied into system: notify owner to relocate connection
downstream of system
5. Check valve is stuck in closed position: repair or replace check valve

Sampling
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.
If a sample port has not been provided, e󰀪uent from the Bio-Film Reactor should be evaluated by collecting a sample from
the liquid above the Reactor Elements. The sample should be collected from 2-3" below the liquid surface to avoid collection
of any oating solids that could interfere with results.
If a sample port has not been provided, e󰀪uent from the Phos-4-Fade lter should be evaluated by collecting a sample
from the liquid above the Phos-4-Fade media. The sample should be collected from 2-3" below the liquid surface to avoid
collection of any oating solids that could interfere with results.
Samples of the UV system e󰀪uent must be collected from a sample port installed downstream of the UV disinfection system.
If an inuent sample is required, the inuent sample should be collected from the pretreatment chamber.
