2. High Limit (HSP1). This high-temperature alarm setting is set at 248°F (120°C). If this temperature is detected at
this sensor. the controller will disengage the main load contactor and sound the audible alarm. This will require a
manual reset of the heater once the overheat event has been corrected.
Pressure Relief Valve:
The heating columns are protected from pressures over 100 PSI (6.9 Bar) by a type 316 stainless steel Pressure Relief Valve
(PRV) mounted on the inlet of the heater. If the column pressure exceeds 100 PSI (6.9 Bar), the pressure relief valve will open
and vent excess water pressure to the drain.
