PROCEPTOR®
TECHNICAL MANUAL
F) INLET, OUTLET AND VENT PIPES
1. Install standard pipe bedding for the inlet and outlet pipes per the sewer design. Attach inlet and outlet pipes to the
Proceptor unit.
If this is a PDI installation, install the flow control provided on the inlet of the tank, with the vent up.
Connect the flow control vent according to local plumbing code and PDI requirements.
2. Vent ports are provided on the top of all Preceptor separators. The vent ports should be extended to above grade per
the plumbing codes governing the installation location. Vents maintain equilibrium with the atmosphere and prevent
the creation of a vacuum within the Proceptor. A gooseneck must be provided at the top of the venting system to help
prevent foreign particles and storm water from entering the Proceptor or plugging the vents.
G) CONNECT EXTENSION COLLAR TO TANK BODY
Proceptor separators are manufactured with a short neck at the top, which is marginally less in diameter than the
extension collar. The fiberglass extension collar slides over the neck. Use only Zurn Green Turtle fiberglass extension
collar (EC2 for 24" dia accessways and EC3 for 36" dia accessways). This collar is designed to fit physically and perform
structurally for this application.
1. To trim the extension collar to fit, dry fit on the tank and measure from bottom of collar to Final Finished Grade. (= A).
2. Measure the height that the frame and cover will add to the collar (= B). Note that the cast iron covers bell fit over the
collar. If the frame and cover is fiberglass, it should be factory bonded to the extension collar already.
3. If the frame and cover is cast iron, allow for a gap (prox 1") between the frame and extension collar so that loading at
grade is not transferred to the extension collar. This gap should be filled with flexible sealant after installation. (Gap =C)
4. Calculate the required collar height: A - B - C = final extension height.
5. Measure and cut the fiberglass extension collar with a grinder or other appropriate cutting tool. Suggested grinding
wheel material is zirconia alumina grit 24.
6. Place the extension collar on the tank.
7. Seal the joint between the tank and collar from the inside, with SIKAFLEX 221 or 255. A standard caulking gun will hold a
300 ml tube of Sikaflex. This joint is normally dry on the inside, but if the sewer line backs up the oil or grease may rise in
the extension. Sealing the joint at the time of installation prevents backed up oil or grease from leaking into the ground.
H) CLEANOUT AND SAMPLE PORTS
Extend to grade or cap as required by customer, design engineer or local code.
I) ACCESSORIES (OPTIONAL)
1.
Suction Line
- If a suction line has been provided as an option on the Proceptor separator, the contractor is responsible
for extending the line to above top of grade using SCH 40 PVC pipe (or equivalent pipe as specified in the plans). The
pipe must be suitable for use as a suction pipe. Limit to four bends. Do not use 90° elbows – use
≤
45° elbows. The
maximum horizontal run recommended is 200 ft, and maximum vertical rise recommended is 15 ft. Install a quick
disoonnect fitting (i.e., Type “D” cam lock fitting) at the outside termination of the suction line for easy connection to a
vacuum truck hose. Ensure that the exposed suction port is protected from damage, ie. use bollards.
2.
Oil/Grease Point Alarm
- Information is provided as a separate dooument.
3.
Coalesoer
- Tanks shipped on their sides with coalescers will have retaining tabs to keep the coalescer in place while tank
is being moved. If equipped, remove the bolts and tabs once the tank is set in place. If left installed, they may impede
removal of coalescer pack(s) for maintenance. Further information on the coalescer is provided as a separate document.
4.
Double Wall
- Connect interstitial leak monitor conduit. Extend conduit with water tight seal. Install accessible port
directly above bottom of tank so probe can be pulled out for inspection in the future. See tank detail and installation
drawings. To install leak monitor device, see Level Monitor wiring instructions provided as a separate document.
