Hi everyone, I’m new here and have a Rapak E3T 11kw 240volt spa heater that I can’t get the heaters to come on. I have a existing main service that is 200amp 3-phase I’m coming out of with a 70amp double pole breaker with #6 building wire going 90ft. to a sub panel with a 60amp double pole breaker. I’m showing 208volts at the heater across phases. I have 24gpm showing on the display and no error codes. The heater has to have 15gpm to turn on automatically after 1min. Of confirmed flow. This heater display also shows present water temperature. The heaters will not come on and this unit has me scratching my head why. Does anyone have any ideas or thoughts as to what the problem might be. Any ideas would be much appreciated thanks.
