ELECTRICAL INSTALLATION INSTRUCTIONS
(continued)
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 home's electrical panel or approved local
bonding point as shown in Figure 3.
NOTE: For all "EcoSilent" pump configurations, the
pump housing is plastic. Therefore, the first copper
conductor attached to the heater must be grounded
directly to the home's electrical panel or approved local
bonding point. this type of configuration does not need
the second copper conductor shown in Figure 3.

Instructions 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

(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.
