Note: In the case of a HazLoc certified product, please ignore additional appendices in
this document as they relate to a standard Hydran M2-X regarding servicing of parts, and
therefore are not applicable for a HazLoc certified product.
For any servicing needs, the unit must be removed from the transformer and returned
to a GE service centre.
Table 1 lists other HazLoc relevant materials for the Hydran M2-X / Hydran M2-X H2
