Very pleased with manual except that a few more details in the drawings might make the job (not yet done, tut-tut) easier. Should be adequate though. Actually I didn't have to pay for this anyway as I was given credit for another item that wasn't quite complete. Good service, then.
Very useful manuals, somewhere graphics not very clear!

SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.
