Switched it on this morning and thought after a while it was taking it's time to fill up. Looked at the gauge and it was at 11 Bar and still going normally switches off at 9.
Had a quick look but I haven't a clue how these things work.
From what I can see there's what appears to be some sort of safety valve connected underneath the switch assy. This normally vents air when starting from empty for about 10-15 secs and then closes allowing the receiver to fill, which it is still doing, however it's going past the switch off point and staying closed. If I pull on the bit on the end of it (after I've switched it off) it vents the receiver for a while before closing again. I'm sure that this is some sort of safety feature but from what I see isn't connected to the switch.
On top of the receiver is a tee piece with a small bore tube which connects into a brass fitting under the power switch, this I reckon is what turns the thing off when it reaches the set pressure (there's no adjustment) so what's going on then?
If the pressure do dah isn't switching off the juice and it's going over pressure why ain't the safety valve venting? Can't have two faults surely?
BTW it's an old Sealy 2HP 50ltr job direct drive.
I know it's difficult to visualise so I'll try to post some pics later.
