There are three heating coils within one element and each heating coil has two wires to
connect the coil to the electrical circuit. The wires for a single coil are directly across
from each other on the longest dimension of the mounting plate.
The heating element in a Power Soak sink is rated at 7000 watts. Electrically, the
Heater is considered as three separate elements, each rated at 2333 watts. To check
operation of the heat element, first turn the power off at the circuit breaker located in the
enclosure on the wall. Disconnect the H2 wire from terminal H2 and the H1 wire from
the triac H1 terminal (and H3 wire from H3 triac, if 3 phase) in the Control Panel. Use
an Ohm Meter to check between each heater lead and the control panel ground to be
sure there is not a connection. Check the resistance between each of the combinations
of heater wires listed on the chart. The heater should be within approximately 10% of
the resistance value shown on the chart. The voltage and phase information is
imprinted on a surface of the heating element mounting flange. See section 8.2 of this
manual for instructions on removal of the heating element.

If the reading varies significantly from the chart above, the heater may be defective, or
there may be a broken wire or loose connection
These two wires are part of the
same heating coil on both the
round rod style and the flat bar
style.
