Hot Spring Spas 1500w circulation heater replacement kit for replacement of current models 2003+ with internal pressure switch cord.
- 2 x temperature sensor locations - hi limit and control.
- 1 x directional flow switch to plumb inline with the heater
- 3/4" barbs for tubing connection
*Its extremely important that you ensure water has flooded the heater and is flowing through the plumbing (primed) after installation and after every drain/refill. Failure of the heater due to 'Dry Running' will likely result if the heater has not properly primed. This is not a manufacturing defect and therefore not a warranty covered failure.
This heater is for replacement of heater models with a second small wire with internal pressure switch
