    *HF SYSTEMS*

    Note that fittings are durable thermo plastic or fibre glass, undue stress during assembly should be avoided.

    Safety Considerations

    • Protect from direct sunlight
    • Empty if temperatures go below 2 c
    • Always read the instructions, do not assume!
    • Consider ergonomics Eye protection
    • Check your system pressure is rated to our system

    Communication

    Since this could be your first exposure to EZ-FLO products note that we are available office hours to offer support on either 0419 780180 or by email: [email protected]

    We have 14 years experience with EZ-FLO, with 1000 ‘s of applications via thousands of clients.

    Ezflo fertilising Australia is the sole importer and distributor for Oceania

    Points To Note

    • Discuss your fertiliser program i.e. inputs with us prior to purchasing PRODUCT.
    • If the packet says “only use under constant agitation” do not use.
    • 99% of inputs work fine but anything that does not go into solution does not work; however, there is an exception: Calcium Nitrate (a highly soluble input), in powdered form is one of the few that does not work in an EZFLO because it forms stable hydrates when supersaturated in the EZ-FLO

    You have received 2 boxes • tank

    • Fittings, including funnel and 3/8” tubing note that the majority of “screw’ on adapters are fitted with “o”rings hand tighten only

    Assembly Steps

    • Tank base assembly
    • Injection head
    • Join “blue” into “blue”: and “clear” to “clear”, push tube all the way into quick-connect fitting
    • Screw injection head onto tank base: do not use side fittings as leverage
    • Fit fertilizer “out” port
    • Fit liquid products “in” assembly
    • If using water soluble simply swap ports
    • Do not forget drain valve

    The tank is now fully assembled

    • Move to location next to injection point
    • Ensure on good solid footing
    • Assume you have fitted the adapter provided, onto the mains
    • Good idea to provide a 19 mm hose point/hose at the system
    • Fit clear 3/8” tubes between the correctly coloured fittings from injection head to adapter, shorten tubes to suit
    • Fill tank with water, ensure no air remains, run irrigation and test all the fittings are tight

    Final adjustment

    • With tank full of water and irrigation system operating
    • Fully open the dial on the rotameter and observe flow rate
    • If you are able to adjust the input between “0 and 20” nothing else to do
    • However if little or no flow with rotameter dial fully open
    • Slowly close the adapter handle, a small fraction at a time
    • Until you can adjust the flow between “0 and 20” using the dial
    • Generally, we need a 20 kpa (3 psi) differential across the ball valve adapter ports
    • If concerned about pressure loss; test the furthest sprinklers with a pitot tube before adjusting the adapter handle, just to check, confirm and sign off!

    Ready to go!

    • Close drain valve then fill with product you have selected

    • Drain tank

    • For ease of filling:

    If you are filling with a “water-soluble” , sometimes powders contain lumps which makes it awkward to keep clearing the funnel mouth

    We suggest you use a 10 or 20-litre bucket. put a few kgs of product in at a time, add a bit of water to make a slurry. Repeat until the bucket is full of slurry then empty into tank using the funnel.

    Repeat these steps
    Fill the tank with the desired quantity then top up with water, remove all air.

    • Close fill valve

    Start injecting

    • Check no air in unit, overflow with water at fill valve!
    • Close fill valve
    • Start irrigation
    • Slowly open appropriate water in and fertiliser out valves on the injection head
    • Dial the GPH ( gallons per hour) injection rate required, convert to litres x 3.8
      Science and chemistry, a.k.a smoke and mirrors
    • If unit is filled with liquid product:
      1 GPH on the gauge = 1 GPH product to the paddock
    • If unit is filled with water soluble product ( prill, granule or powder):
      Refer to the manufacturer’s label as to its solubility, normally in grams per litre So if the solubility of your product is 250 g/l then you need to dial 4 litres on the gauge to get 1 kg/h out to the paddock.
