Hello. I have purchased couple of bathroom extraction fans from Mingfans in Auckland to install in our bathrooms each. I will pass these onto the sparky to install and do the ducting as we have other work we need sparky to complete on the house but out of curiosity I wanted to test suction performance and noise so when I opened it all up, the end plug has a 4 pin connector in total. We did get timers installed in both fans set to 10 minutes. I emailed the company and they advised of below.

"Just cut that plug as that plug is special we have for testing and will have four cords of wire. black , brown, blue and earth and then your electrician wire to that wire with box will do

Black to constantly 240v all time
Brown to switch
Blue is N "

I am sure the sparky will understand once I pass it to them but incase they did not, I assume that either sparky will replace the connector plug with a new one or they will remove the plug altogether and hard wire it to main and switch on wall in the bathrooms?









Do whatever you want to do man.

you can buy sockets for these, but easier just to get your electrician to chop it off and hard wire using a junction box, much cheaper than buying the socket.

Thanks. I believe the timer is also installed inside the fan speed selection box which is very light weight so I imagine it’s got plenty of free space inside. Can the sparky use the fan selector box also as a junction box to run mains wire into directly?

And any online links to a shop someone can point me to wanting to buy few bungy cords to provide to sparky so they can hang the fan unit and associated ducting to the roof framing to reduce noise even further. The ducting I purchased is acoustic and I went with 200mm duct size fan and 200mm ducting to reduce noise and keep performance to maximum.

As far as using the timer box as the junction box, depends on available room and how the flex currently connects inside the box.

 

 

 

Bungie cords for mounding the fan, yeah - nah, the cords will eventually break. best way is metal strapping - ideally follow manufactures instructions.

Thanks. Steel strapping reel is priced ok but looks like I will need to purchase a steel strapping device as well which is over $100 in most places. I see Kennards hire rent it out for $54 for 1 day. If that includes few meters of steel strap as well then I will hire this to the sparky for 1 day as I would be very surprised if he has a steel strapping device.

you just need the steel strapping with hole in it, screws or nails in to the wooden beams and screws in to the fan at the mounting points
