** Plug-in voltage indicates closest IBPAN preference. The GRR unit-temperature, the element maximum-temperature, the rated amperage (current) or power, cannot be exceeded in any configuration of use.  The configuration of use will change with end caps, load, flow, placement of control thermocouple and extent of insulation that is ordered.  If not puchasing a MHI control system with the GRR unit/model or if choosing multiple units, please confirm the RR volts of the unit with the sales agent.
