Autopilot recommends that a licensed electrician or certified electrical contractor perform the electrical connections.
DANGER: ensure that the electrical panel or filter pump circuit breaker is turned OFF before wiring this unit.
Your
Lectranator Soft Touch Model ST 48
Control Box comes pre-wired from the factory for 230VAC (1.5 amps max draw) and can also
operate on 115 VAC, (3.0 amps max draw) at 50/60Hz. 1.8m (6ft.) of AC lead wires are provided with the unit and are located on the bottom
base plate of the control box along with the Cell, Tri-Sensor and optional ORP Interface connections.
Converting to 115VAC
is accomplished by accessing the circuit board, rewiring, and attaching the included jumper as shown below.
Remove the cover (see page 10) to access and ensure that the Jumper Connections on the circuit board marked “TRANSFORMER
PRIMARY” are matched to the LINE IN voltage. Follow all state/local codes for electrical installations.

in conjunction with your circulation pump.
Cell Cord
.
Each Cell Cord contains (2) Banana Plugs that attach to the (2) Banana Jacks on the bottom of the Control Box.
Polarity does not matter. The other end of the cell cord has a three-position plug that connects to the cell in any direction. See page
11 for service instructions.
Tri-Sensor Cord
.
The Tri-Sensor Cord connects to the keyed 6-pin harness on the Control Box Base Plate. The opposite end of
the cord connects to the Tri-Sensor Assembly with a locking ring quick connect. Align the grove and keyway on the connector and
twist the locking ring to ensure a proper connection. Refer to the instructions on pages 10 & 12 for diagrams and additional
instructions.
ORP Connection
.
When an ORP Chemical Controller is interfaced to your
Lectranator Soft Touch Model ST 48
, the Chemical Controller
will remotely control the SANITIZER Output. Adjust the output level to 0% and connect the ORP controller to the 2-pin connector
on the Control Box Base Plate. When the ORP is activated, the output will indicate ON with the display showing 0%.
WARNING: THE ORP CONNECTIONS ARE DRY CONTACT INPUTS, DO NOT ENERGIZE THESE
INPUTS! DAMAGE TO THE CONTROL BOX WILL OCCUR AND WILL VOID THE WARRANTY.
