Page 4: Scope Of This Service Manual
This service manual is made in order to aid service technicians when servicing and troubleshooting on the Gram Gastro 07/08 product range, and in particular related to the electrical controller. The service manual is not intended to be handed over to end-users, since unintended changes of settings potentially can cause situations where the temperature inside the cabinet cannot be kept as intended, (high foodstuff temperatures can occur if wrong adjustments are made). -
