FITTING INSTRUCTIONS
Downpipe fits into SUPADIVERTA top inlet and to outside of bottom outlet.

100mm x 50mm RECTANGLE DOWNPIPES

Step 1. Measure, mark then cut out 342mm section of downpipe.
Step 2. Position SUPADIVERTA to rejoin the upper and lower downpipe sections.
A 3mm gap is needed between the downpipe and wall to fit the SUPADIVERTA and enable easy removal of the inspection lid. Fit spacers between the downpipe and wall if needed.
Step 3. Secure downpipe with downpipe clips. Spacers may be needed.

90mm ROUND DOWNPIPES

Step 1. Purchase two downpipe adaptors (prior to hiring plumber).
95mm x 45mm x 90mm adaptors do not require a coupling, fit into the SUPADIVERTA inlet and are recommended for a snug fitting to the outlet.
100mm x 50mm x 90mm adaptors require an internal fitting of a section of 100mm x 50mm PVC to couple the adaptor to the inlet. This provides a neat and firm fitting.
Step 2. Carefully measure, mark then cut downpipe to size. As adaptors vary between manufacturers, Aquatrek is unable to indicate the precise length of downpipe to be removed.
IMPORTANT: it is the adaptors internal fitment that needs measuring, not the height of the adaptor!
Step 3. Fit SUPADIVERTA and adaptors to rejoin the upper and lower downpipes. There is no need to glue or screw the adaptors to SUPADIVERTA. A 3mm gap is needed between the downpipe and wall to fit the SUPADIVERTA and enable easy removal of the inspection lid. Fit spacers between the downpipe and wall if needed.
Step 4. Secure downpipe with downpipe clips. Spacers may be needed.

OTHER SIZE DOWNPIPES

Adaptors are available to fit many other downpipe sizes. Contact AQUATREK if you have difficulty in locating suitable adaptors.
IMPORTANT: Purchase adaptors prior to hiring a plumber.
SUPADIVERTA normally will not require additional bracing.
Carefully consider intended usage prior to selecting the height position.
Check that the filter is properly positioned (as per box diagram).
Use Teflon tape on threads of supplied fittings. Do not over-tighten.
Some outlet fittings, for example elbows, are best fitted prior to securing downpipe.
Tanks can be optioned or retro fitted with additional outlets.

IT IS ESSENTIAL THAT THE VERTICAL POLYPIPE REMAINS VERTICAL AND CONNECTS TO HORIZONTAL POLYPIPE AT A 90 DEGREE ANGLE TO ENABLE PRIMING. 19mm polypipe is recommended for the vertical feed to horizontal 25mm polypipe. 20mm BSP outlets accept various low pressure pipework. Using polypipe is the easiest and lowest cost option. Polypipe can be painted if first treated with a suitable bonding agent.

QUICK PRIME

The 2nd priority outlet is quickly primed when a 13mm bleed tube is fitted at an upper level between the 2nd and 3rd priority hoses. Fitting reducing tees into both hoses and connecting the tees with 13mm tubing allows the 3rd outlet to act as a snorkel to quickly purge trapped air from the 2nd outlet.

This method is recommended to speed priming of 25mm polypipe fitted to the 2nd priority outlet.
19mm POLYPIPE VERTICAL DROPS DO NOT REQUIRE QUICK PRIME.
25mm polypipe is generally used over longer distances and in high intensity rain areas.
Fitting 25mm polypipe directly to the 3rd priority outlet is not recommended.
AQUATREK recommends using a flexible UV stabilised 13mm tube in preference to 13mm polypipe as the quick prime bleed tube.

6mm ALTERNATIVE
Quick Prime is also easily achieved by fitting 6mm take off adaptors to the upper levels of the second and third priority vertical drops and then connecting the adaptors with a 6mm tube. While not as fast as 13mm tube when purging air pockets from a 25mm drop, it is nevertheless effective unless the SUPADIVERTA has been installed unusually high.

HANDY HINT: Tapping a 6mm take off adaptor into a 19mm or 25mm polypipe after piercing a hole with a punch tool can be difficult and the tool can cost around $4 - $5. It is often easier to carefully drill 2.5mm & 3.5mm holes through one side of the 19mm & 25mm polypipes respectively and then fit the adaptors.
A 6mm Quick Prime fitting can be purchased from AQUATREK.

CAUTION

SUPADIVERTA is designed for use with 19mm vertical drops and syphonic flow is all about having discharge pipes running full of water at increased velocity during heavier rainfall. The quick prime solution is only shown to assist householders who have fitted 25mm x ¾" BSPM directors to the second outlet ( further information).

HINTS

• Householders should address any gutter debris issues prior to fitting SUPADIVERTA.
• Regular flushing of the downpipe and storm-water is recommended.
• Syphonic drainage is vastly superior to gravity drainage and the inlet inflow often exceeds the maximum capacity for gravity but is insufficient for syphonic. In this situation, flow will alternate between the two mediums.
• Use 25mm polypipe when diverting to a tanks top meshed inlet and fit end with a 90 degree elbow to prevent splash.
• Head pressure decreases as a tank fills.
• Use 19mm polypipe if diverting to drip hoses.
• Use a 25mm horizontal mainline when diverting from more than one additional downpipe to a tank.
• Rises (highpoints) along the polypipe should be avoided as these can create air locks.
• If an outside T.V. antenna (bird roost) is close to a downpipe, consider harvesting other downpipes if the water is to be diverted to a tank or pool.
• When cleaning gutters, wrapping 2 or 3 layers of cling wrap (overlay from bottom to top) around the filter will prevent any passage of debris to the internal reservoir.
• If a film builds up on the filter mesh, cleaning is best done with a soft brush and a mild detergent. Do not use abrasive and coarse household cleaning products.
• If painting adaptors and SUPADIVERTA, it is best to use a suitable priming agent prior to painting.
• Inline taps fitted to the outlet hoses are a handy accessory.

The central outlet will scavenge much of the heavier debris (sand) that passes through the 750 micron mesh filter and fitting a short polypipe and inline tap will allow capture of this debris. To divert the polluted first flush, a first flush kit designed for SUPADIVERTA is available from AQUATREK.

10mm rainfall per hour on 50 sq. metres of roof servicing one downpipe is an average of 8.3 lt/min - 500lt/hr.

MAINTENANCE

• For quality rainwater harvesting, householders should address any gutter debris issues prior to fitting SUPADIVERTA and regular gutter inspections are recommended. A new technology surface tension guttering system can be found at www.leafsafeguttering.com.au
• AQUATREK strongly recommends against the use of filtering devices placed into downpipe drops. Many such devices easily block!
• The filter will rarely need cleaning and a quick back flush with a hose negates the need to remove the filter. If a film builds up on the mesh, cleaning is best done with a soft brush and a mild detergent. Do not use abrasive and coarse household cleaning products.
• When cleaning or flushing gutters, wrapping 2 or 3 layers of cling wrap around the filter will prevent any passage of debris to the internal reservoir. Wrapping from bottom to top provides a suitable overlay.
• Regular flushing of the downpipe and storm-water is recommended.
