This is the latest No-Fault PDR Titanium heater. It replaces all previous no fault versions for Hot Springs and Tiger River spas from 1995 to 2002 including the nofault 6000,5500 and 1500 cartridge style heaters. It also replaces the tri-bend heater. The heater is designed with a double pass to heat water ultra efficiently. It is used in both 115v and 230v hot tubs.
This Universal Retro-Fit heater wired at 230 Volts is rated at 4000 or 6000 watts. If your spa is running on 230 volt operation only, then you can select the 6000 watt version for faster heating times. 4 KW 73791. 6 KW 73790
This heater does not come with a plug on the end of the power cord. In most applications it is hardwired into your control box.
Your existing tube will retrofit easily to the PDR titanium heater. Your old sensors simply unscrew from the old heater and thread into the new one.
The PDR design eliminates the reset button. Resetting this heater is accomplished by cycling the circuit breaker to the heater/tub.
This heater is a universal fit for serial numbers
