Hello everybody 'Lurgs' here welcome to my channel and today it's how to prime and commission the
Mira Advance ATL Thermostatic shower, now this is the slightly older model, I've got another
video for the newer model which is a slightly different procedure, now on this particular model
there might be a reason that you need to prime and reset the shower if you get a 'Water Supply' error
or you actually get the 'Reset' light come up on your Mira shower now if it's a Water Supply error
you can try a different shower head because these do get blocked up with bits of grit and limescale
or maybe your shower's not running efficiently and you just want to prime and recommission it,
right let's get cracking, first thing you need to do is turn off the shower at the switch
and just to be double safe you can switch off at the RCD unit, then you need to remove the
front panel you do this by removing this base plate screw so unscrew that anti-clockwise this
just holds the front panel in place you can if you want to remove the shower hose which makes access
slightly easier but you don't have to, I've just removed that just because it makes it slightly
easier now pull at the bottom of the shower it should just pull away from the wall don't rip
it off the wall though because it's got a ribbon attached to the front panel for the electronics
so just be careful when you pull it away hopefully you haven't siliconed it against the wall,
that's the cover for the electrics so you need to put that back in
that's why you don't pull it off really hard so you need to unattach the ribbon
literally just pull it out towards you that just unplugs
put the front panel somewhere safe and now we need to prime the shower
let me do this by using this button here remember you do not need the electricity on for this you
don't need the power on so push that button down hold it down for at least 10 seconds
and then the cold mains water will come through the shower head
leave it for a little while
then again push that button down hold it down for at least 10 seconds
you will get a little bit of water coming out of the button where that bleed valve is so
afterwards you need to make sure that you mop up any water at the bottom of the base of the shower
and then we do it a third and final time push down that button hold it for at least 10 seconds and
whilst I'm doing that there's a link above now about how to remove mould from silicone sealant
in your bathroom with no scrubbing at all it's a really great tip, this bathroom could definitely
do with some of that! Excellent that means the shower is now primed as I mentioned earlier
make sure you mop up any water at the base of the shower because that button does leak
put the electric cover back in that just slides into place
now put the front panel back on remember to plug the ribbon back in this plug can only
go one way up because it's got a little divot in it let's just plug that in whilst I'm doing
that there's a link above now about how to keep your washing machine hygienically fresh
put the top of the panel in first towards the back of the shower
so get that lined up and then push the bottom in
it should all be fairly natural don't try and force it there we go
then remember to put the base plate screw back in just to hold that
front panel in place screw that in clockwise always put it in with your fingers first hand
tighten it then get the screwdriver on it and tighten it all the way up,
then remember to turn the electricity back on and turn the shower back on now we need to commission
the shower. Within 30 seconds of turning the power on if you hold the 'Flow' button and the 'Start'
button in at the same time with the temperature dial set to the max as soon as you hear the first
beep then release the 'Start Stop' button as soon as you hear the second beep then release
the 'Flow' button now the water will flow for at least a minute while it's commissioning itself
and you just need to wait for that do not interrupt this cycle at all so let that finish
Either you'll get an error because you've still got a fault or it will finish and once
it's finished you can then turn the shower back on again and set it to the desired temperature,
then press the 'Start Stop' button to turn it off again it's important that
you let all the water run out the shower head before you switch it off at the main switch,
and that is the shower primed and commissioned if you've still got an error then you'll have
to contact the Mira helpdesk or your local plumber who deals with Mira electric showers,
after all that hard work it's time for a lovely cup of tea!
