Need help with a manual for this up right freezer. Customer said it freezes fine, runs steady, and he is right, as my gauge says -40 and it does run steady. He was told it was the temp control board, so he ordered it, and installed it and that did not correct/or control the temp. So he was going to order the lower board, and they wanted 170.00 for it, and went and bought a new horizontal. So he gave it to me. I plugged it in, and hes right. On the front monitor, it flashed from CE to 48 degree, but inside its -40 with my gauges. So need the manual to figure this animal out.

Only a few years old, in mint condition.
