    Hooking up BZ-40 - Water Purifier/Electricity

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi guys:

    I am looking at $330 for a two stage water purification system. The good news if there is any is that I will have a tap put in so it can be used for drinking water too. First stage is one micron sediment and the second stage is carbon/hexaphosphate (for softening).

    The other thing is that I need to put in a 15 amp circuit which will cost $150.

    It all needs to be done but if there are cheaper ways on the water purification let me know.

    I have to protect my investment.

    Thanks,
    Grant

    Phew, I was surprised by your previous post that said a 2550 watt unit only needed a standard powerpoint (and thought I had forgotten the last of my electrical engineering training from a previous life) :o

    2550w / 240v = 10.6amp

    With most 10amp "safety switches" set to a litigation safe level of 9.xamp I would expect them to throw each time you turned the machine on.... unless you opted for the 3" nail ;D

    As far a water purifiers go Im even less of an expert but I do know that all the 1 micron ones that I looked at previously had REALLY low flow rates and that is when they are brand new. Depending on how clean (or not clean) your water is as to how long it will take for the flow rate to halve. You might find that using a 5 micron system will be a better compromise between flow and filter life.

    Most of the canister systems have different cartridge options that will get you to the results needed, you just need to know how much water the new toy needs (litres/hour)

    Andy:

    Im not sure there is really a 10amp restriction on the circuit as such. Each power circuit will take 20amps. We think the kitchen or the laundry is on its own 16amp circuit anyway as this was something I got done when we moved in along with a safety switch. I have forgotten though what I had done.

    I have a thing about making sure that there are plenty of volts.

    The real problem is just the risk of tripping the circuit. A standard fan heater is 10amp this is about 11amps, it isnt much of a difference.

    Andy:

    Re the water purifier, that could be a good point about the flow rate, I will have to find out from Barazi what the required flowrate is. I got told by Peter from Supreme that 4 micron filter is sufficient.

    Thanks,

    Youve probably considered and discarded this option: a Brita jug filter. The cartridge elimnates calcium hardness residue, chlorine and impurities, and at $10 each, lasts for 150 litres -- in our case where filtered water is used exclusively for the coffee machine and odd drink thats about 3 months.

    It works out to some 6.6 cents a litre. The jug holds 2 litres, and filters fairly rapidly, down to 3 microns.

    I think the problem with that is Robusto that his machine needs to be plummed in.

    I have a Brita and it rocks! I only paid $10 for it ;)

    Wattgn, Dont quote me, but Im fairly sure there is an inline, under the sink DIY Brita filter available. Pretty sure I saw it in Kmart, but then I have a vivid imagination and could well have dreamt it.

    I use a Brita filter attached to the fawcet and manually top up the Silvia, and while mine doesnt rock, it does do the job ;)


    Remember, girls and boys, always use a licensed plumber. ;D

    Good luck

    Hi Grant, just another point in relation to the use of a safety switch. *
    Each of the power circuits have a current rating, ie 10Amps, 16Amps etc. *This is to protect the wiring of the house, not the people in the house. *
    The safety switch, which is usually used as a main switch, has a very low current rating, usually 20 milliamps. *This is to protect the people inside the house from being electrocuted, when they stick knives in the toaster, drop the hairdryer into the sink full of water, etc. *
    The safety switches detect this current that is flowing through the unfortunate person, which should be flowing back through the circuit, and trips the safety switch, preventing the death of that person. *
    As a consequence of this low current rating, safety switches are notorious for tripping when certain electrical appliances are used, mainly the ones where electricity is coming into contact with water, ie irons, clothes dryers, kettles, etc as the safety switch thinks that someone is being electrocuted.
    At the end of the day, an espresso machine is a big complicated kettle, which may cause the safety switch to trip, as it thinks that someone is being electrocuted.
    The point of all this rambling is that I would suggest having the machine hooked up to a separate circuit, of the appropriate current rating, which is not connected to a safety switch. *Any good sparky could do this for you for a moderate fee.
    All the best,
    Steve.

    Hi Lovey:

    I think the safety switch saved my electronics box in my Bezzera which costs $250 and it cost $150 to install so I am $100 ahead! :)

    I got water in it when I was messing with the insides of the Bezzera. I could actually see where there was a short circuit at the bottom of the board but instead of 16Amps going through it, it got only 20mA. The Bezzera doesnt trip it in normal circumstances.

    I have never had trouble with them tripping, not once that I can remember in fact. I think it did trip once when one of the heat lamps blew in the bathroom but it wasnt a drama.


    Im going to keep it wired in with the safety switch unless there is a good reason.

    It is quite handy too if you actually drop your toaster in the bathtub while enjoying breakfast (with an espresso of course).

    Hmmm,

    I dont think it is a good idea to take any kitchen appliance (no matter where it is installed) off the Safety Circuits in your house. Anything that is earthed and metallic, and said metal can be touched by a person during the normal operation of the appliance should be connected to the safety switch circuits in your household. I think it is even now the law that this should be done.

    If you did have an appliance whose power draw was consistently above the nominal 10 Amps of a standard household power circuit, then it should be wired directly to its own 15 Amp circuit but still within the Protected zone of the Safety Switch in the main switchboard. It doesnt pay to muck around with safety where electrical appliances in the home are concerned, the price that can be paid is the ultimate one :o .

    Cheers,
    Mal.
