OPERATION

WARNING: Prior to operation, review the Important Safety Instructions	Fig. 1
listed at the beginning of this instruction manual.

Once the heater is installed and the whirlpool pump is operating, the heater is totally automatic. The heater will help maintain the temperature of the water in the bath.

Pressure Switch

The heater is equipped with a preset pressure switch. The pump must be running with water flowing in the whirlpool to allow the heater to turn on.

Indicator Light

This light turns on whenever the heater is operating.

The heater includes an exclusive "Intelligent High-Limit". This safety circuit will not "false trip" from hot tap water. It will only turn the heater off if the thermostat fails. If the high-limit trips frequently, call a service technician.

To manually reset the circuit in the event that the “High-Limit” switch has been activated, simply (1) Turn off the whirlpool pump. (2) Drain water from the tub. (3) Remove power from heater by unplugging at receptacle or turning off circuit breaker. (4) The heater circuit will automatically reset in less than 15 minutes. (5) Restore power to the heater. (6) Whirlpool bath is now ready to use.

ELECTRICAL CONNECTIONS

Install a separate 120VAC / 15AMP dedicated circuit with GFCI (Ground Fault Circuit Interrupter) protection.

At initial start-up with power ON, push the GFCI test button. The reset button should pop out. Push this button in to reset. If the GFCI fails to operate in this manner, there is a ground fault or malfunction, indicating the possibility of electrical shock. Turn off the power and do not

use the bath until the source of the problem has been identified and corrected.

1.Route two separate branch circuits to the junction box near the whirlpool as shown in Figure 2. Each branch circuit MUST BE GFCI PROTECTED and must use copper conductors only.

2.Ensure the heater and pump are properly GROUNDED and BONDED as required. Attach the 8 AWG solid copper conductor supplied with the heater from the heater bonding lug to the motor frame bonding lug as shown in Figure 3. The conductor is secured to the lugs using set screws. The motor frame shall have a second 8 AWG solid copper conductor connected from the frame bonding lug to the homes electrical panel or approved local bonding point as shown in Figure 3.
