Hi, @AmberLauren! I can't believe we have the same kiln. I've not been able to find any one else who's even heard of 'Arterial Engineering Works' so far!
I didn't get a manual for the kiln but I found the manual for my control panel (IPCO 3300) relatively easily and that's all I've really needed so far. Did your kiln come with a control panel? I was reallllllly lucky as mine came with the panel, the (damaged) thermocouple and an industrial circuit breaker.
When I was sorting out the thermocouple (I'd only learnt what one was ten minutes before my original post!) I ended up sending photos to 'Peak Sensors' and explaining what I needed and they worked out the rest. I posted my old thermocouple to them and they reused all the parts of it they could salvage but I think it probably cost me about the same as if I'd bought a new one in the end, including postage etc. I know it's an industrial Type R but it also has a ceramic sheath around the wire - that can withstand the top temps of the kiln - and is the right length so as to reach but not be too in the way (can you tell I had a lot of fun trying to figure all this out with them? They were SO helpful...and patient). I'll attach a photo of my order so you can swot up a little bit but what I WILL say is the diameter of the ceramic sheath was sliiightly too big so I've had to make the hole a bit bigger (just the fire brick at the top) to allow it to drop down all the way to the flange/collar and sit flush with the top of the kiln.
And here's the diagram they sent me:
Am I making this less or more confusing?
As for wonderful creations...none yet. Life's been a bit hectic recently BUT it works! I've switched it on and everything seems to be in working order. I've just ordered myself some cones to monitor heat work and see just how hot it'll go (the elements are OLD) which, knowing my luck, will reveal a whole host of new problems and things to learn about but fingers crossed we'll be making stuff in the next couple of weeks.
I hope some of this was useful and not completely overwhelming. Hopefully we can help each other out in the future now we've found someone with twin kilns!
Good luck! Here to (try to) answer any other questions you have.
