Has anybody got a service manual for the Zannotti gm 2 walkin freezer unit. One my customers has bought a second hand
one and has run it as a fridge for only a couple of days and its cutting in at 11 deg andcutting out at 14 deg. I'm suspecting that the controller is faulty as its not ackowledging when the buttons are depressed and won't let me change anything.

Cheers.
