PRODUCT DETAILS

A high volume first flush diverter, designed

specifically for inground applications. Divert the

dirtiest water and transform your rain harvesting

system from “wet” to “dry” with this large volume

inground first flush diverter.

The unique manifold design uses standard

100mm or 4" pipe to create a high capacity

storage and diversion chamber for your first flush.

Using these smaller pipe sizes makes it easier to

source pipe and assemble the system, when

compared to using large diameter pipe on

traditional high volume diverters.

Installation WHAT’S IN THE BOX? TOOLS/MATERIALS YOU MAY REQUIRE Delta chamber end caps x 2 Tape measure Cage/Seat & Ball Marker pen Chamber support spacer Saw 100mm (4”) socket reducer File Transparent Rapid Release Exit Funnel Priming fluid Electronic Release Valve Solvent weld glue Primary Filter Screen Screws/Anchors Screw driver Drill 100mm (4”) pipe INSTALLATION 1 - It is a requirement to install a rain head upstream of any down pipe feeding the Delta In-Ground First Flush.

Figure 1 Suggested Installation Orientations 6 - Using priming fluid, clean all internal sockets of both Delta End Caps and each external ends of the six Chamber Pipes. 7 - Apply solvent weld glue to the Max Chamber adaptor and glue it onto the upper end of your diversion chamber. If you aren’t using the Max Chamber adaptor you can disregard this step. 8 - Working with one Delta End Cap, apply solvent weld glue internally to a Chamber Socket and then externally to one of the Chamber Pipes.

10 - Working quickly, apply solvent weld glue to each of the six internal Chamber Sockets of the remaining Delta End Cap and then externally to the six Chamber Pipes. Quickly bring the Delta End Cap together with the six pipes by first aligning three pipes and sockets on one side and then rolling onto the remaining three pipes. Using some force, push the Delta End Cap down onto the Chamber Pipes ensuring the pipes enter the socket fully and hold in position until secure (Figure 3 - Delta Diagram).

13 - Excavate the installation location for the T-junction, assembled Delta Chamber and adjoining pipe work. Trenches should be wide enough to include a minimum of 75mm bedding and overlay support and a minimum of 100mm side support. In non-trafficable areas allow for a minimum of 300mm cover (measured from the top of the Delta/pipe to the ground surface). See Figure 5 for installation. For further information we recommend using AS3500.2:2018 as a guide.

Figure 6 Installing and setting up the Electronic Release Valve 6a. Insert the Primary Filter into the end of the First Flush chamber. It should fit snuggly into the socket on the end of the pipe 6a. Insert the Primary Filter into the end of the First Flush chamber. It should fit snuggly into the socket on the end of the pipe 6c. Attach the Electronic Release Valve by first installing the 25mm x 20mm (1" x 3/4") reducing adaptor and washer to the 25mm (1") thread of the screw cap. Washer 6d.

6e. Attach the valve at the union and orientate dial for easy access. 6f. Remove the waterproof cover from the Electronic Release Valve. O-ring 6g. Ensure the reset interval and drain time control knobs are in the "RESET" and "CLOSED" positions. Carefully slide out the battery box and install two new 1.5-volt AAA batteries. "Reset" "Closed" 6h. Test the unit by turning the drain time knob to the "OPEN" position. You should hear the sound of the motor within 5 seconds.

6i. Ensure that the reset interval and drain time knobs are in the "RESET" and "CLOSED" positions. NOTE: The first time you program the Electronic Release Valve it will not begin to operate until after a time delay equal to the setting of the reset interval knob you select. The Electronic Release Valve starts to keep time when you set it. It is important that you set the timer at the hour you want it to operate.

NOTE: NOTE: 2 x Delta End Caps hold approximately 20.24 litres. (Excluding the pipe sockets of chamber.) 2 x Delta End Caps hold approximately 6.52 gallons. (Excluding the pipe sockets of chamber.) The above figure is total volume of delta end cap excluding the liquid contained within the 6x pipe chambers.

Maintenance It’s important to ensure that your first flush diverter outlet remains clear of any debris. If your outlet becomes blocked, the chamber will not empty and the first flush of water will not be diverted when it rains. To ensure the flow of water out through your Electronic Release Valve, periodically remove from the Transparent Rapid Release Exit Funnel to check for any build-up of matter. Remove primary filter plus ball, and clean if required.
