HotSpring Tiger River Spas HEATER 6 KW NO FAULT 73790 Watkins
Introduced in 2010, this 'NO FAULT' PDR Titanium Heater is HotSpring Spas' latest cutting edge heater. Featuring a double-pass sleek design, this heater replaces all previously discontinued heater styles. By passing through the heater element twice, your spa water heats in two stages. Factory approved replacement for all 115 volt 1.5kW and 230 volt - 6kW installations for all 1995-now Hot Spring and Tiger River spa models, this heater is under factory warranty. Use your existing 3/4" vinyl tubing to attach to the NO FAULT heater. To aid in ease of installation, the thermistors have different thread sizes to insure they can't accidentally be reversed when re-installing them into the new PDR heater. Also, the wires have different tips on the ends, to insure they can't accidentally be plugged into the wrong port on the IQ Control Box.This replacement heater doesn't have a plug on the end of the power cord like on the 1995-1996 spas. In most applications, the heater is connected directly inside the spas control box. If your existing heater plugs in to the bottom of your control box, you may need the appropriate adapter. Note: If your existing heater has an additional wire plugged into the IQ2020 main board, you will need to either order the PDR heater with the built-in pressure switch (72795) or add a Flow Status Jumper (72768) to P34 on the main board. Using the heater with a built-in pressure switch is recommended.
