York AWHC40L

Hello There,
We have a problem with a VERY old (circa 1983) York chiller model number AWHC40L50E. Would anyone out there have a wiring diagram for it?
Thanks in advance!!

Bones.
I would assume that model is pre .pdf's.
IE. Too old to be in a pc format.
Good Luck all the same, maybe someone has it in hard copy?

Thanks all,
I've been in touch with York UK but they didn't hold out much hope!

So what's the problem with the chiller then bones?
There are a good few active x York guys on the forum.
So maybe someone can help?

Hi Grizzly,We've been through the usual: flow switch HP,LP, compressor thermistor control. The cam timer (yes...it's got a cam timer!) turns to the start position but it doesn't start. The controller is a very quaint unit with rotary knobs but it seems to be OK as it drives the cam timer. The cam timer micro-switches are all OK but there are loads of relays for the solenoid valves etc. Would take hours to fault find!
