Instructions for repair
This Service – Manual contains instructions for the repair of MEMMERT baths. For maintenance works please see the Operation Instructions added to each unit. We point out that actions which require disassembly (even in part) of the unit have to be carried out by experts only.
The dismantling and dismounting of parts is described in this document down to the module level, because spare parts usually are replaced as complete modules only.
Please note the safety instructions and general directions of the
Operating Instructions added to the unit.
ATTENTION!
Before removing the side panel – pull out the plug
and remove the liquid of the bath !!
Separating the unit sets free raw metal edges – therefore
always use gloves!
This Service – Manual describes the steps for the dismounting of the unit. Reassembly is done in reverse order, if not stated differently.
