Install the UI PCB and IR Module
If required, remove existing UI PCB and replace with the contactless PCB kit. Please ensure the
correct UI PCB is fitted to the correct water options version of the machine you are carrying out the
contactless retrofit to.
IR Module PCB connection
Pedal PCB Connections
IR Module PCB Connections
Ensure the correct IR module water options is
used in the correct machine, for example, Hot and Cold IR module is used with a Hot and Cold model.
When connecting the IR module to the PCB, ensure Hot is connected to Hot and Cold is connected to
Cold.
It is also important to make sure the signal and ground wires are connected the correct way. Due to
the pedal system not requiring correct polarity, ensure signal and ground are connected correctly for
the IR module.
Helpful tip
: If the IR module does not operate, the signal and ground may be the wrong way around,
by switching the signal and ground around the other way may solve the issue.
