8.2c Assembly – Place the gasket on the bottom surface of the heating element
mounting plate. Insert the heating element though the opening in the back wall of the
wash tank. Push the wires through the center opening and align the studs with the
mounting holes on the bottom surface of the tank. Install the nuts on outside surface of
the tank to secure the heating element to the bottom of the tank. Tighten the nuts to
pull the mounting base snug against the bottom surface of the tank and then turn the
nut another ½ turn to secure the element. Fill the tank with a few inches of water and
check for leaks around the heating element mounting holes. Connect the heater wires
to the terminal block. Machines that have three power supply wires (L1, L2, L3)
attached to the terminal block will use the three phase connection and machines that
only have two power supply wires (L1, L2) attached to the terminal block will use the
single phase connection.
Install the cover over the heater access opening inside the wash tank. Be sure that the
cover is seated well with no gaps around the edges that will allow debris to enter the
pump suction manifold. Start a wash cycle and check the operating temperature of the
water. The water should heat to approximately 115°F within two hours.
The heating element access cover must be installed while the
pump is operating. Failure to install the heating element access
cover will allow objects to enter the pump suction and damage
the pump impeller.
