This Watkins No Fault Heater is the factory replacement for the many Hot Spring, Tiger River and Limelight models. This heater is the 6kW/1.5kW version and comes with a built in pressure switch.
Note: This heater has a built in pressure switch which plugs onto the P34 port on the IQ 2020 motherboard. The advantage of this heater over the 73790 PDR Heater is that the IQ 2020 spa control system will alert you when this heater has shut down by displaying a blinking green Ready light and a blinking red Power light on the control panel. The 73790 PDR Heater will just trip off internally with no alert other than the spa water cooling. This heater is a 6kW (6000 watt) when wired 230 volts or a 1.5kW (1500 watts) when wired 120 volts.
Note #2: It is highly recommended to purchase new thermistors, 79006 and 79005, with this heater. The inlet thermistor port on these style heaters may require a wrench to thread in the thermistor. If your existing thermistors plug in to the OUTSIDE of your control box, please use item 78970 and 78969 as replacement thermistors. This heater comes with new thermistor o-rings.
Note #3: For tubs from 2004 and newer, you will need to remove the spade connectors on the end so the bare wire will fit into H1 and H2 terminals.
