For proper operation of the HTK, all wires listed above must be pulled and terminated as explained in
the following section.

Wire Terminations
The wire terminations should proceed as follows:

One side of the three power supply wires (120VAC HOT, 120VAC NEU, and 120VAC GND)
should be attached directly to the electrical service panel supplying power to the installation.
They should be connected to a 15 AMP circuit breaker and the HTK should be the only de-
vice on this circuit. The other end of these three wires should be routed into the HTK through
the installed conduit. The wires should be terminated as follows: Refer to “Power Supply”
diagram on page 17.
NOTE: The removal of the Power Supply and duplex outlet is rec-
ommended for ease of connection to backside of duplex outlet
NOTE: The signal presented to the car wash controller is a nor-
mally open, dry contact relay closure.
