Hayward HLXPLCONTROL Installation Manual page 11

If using an I/O expansion board, mount the HLX-DSP-MOUNT (sold separately) onto the Main Board as
shown below. Once installed, slide the I/O expansion board into the notches in the guide rails of the
plastic scaffolding. Reconnect all wiring connections to the I/O expansion board that were previously
removed, then push the board in until it plugs into the connector on the Main Board.

The Controller comes with a 15 ft cord and plugs into the Controller Bridge Board. It should be mounted
in a location that is convenient for the user to view and change pool/spa settings and within range of
the home's wireless network access point. When considering the mounting location, make sure there
is enough clearance above the enclosure so that the flip door will be able to be opened fully. Also be
sure to allow enough clearance below the Controller to access the USB and Ethernet connectors. For
best viewing results, position the Controller where it won't be subjected to direct sunlight.
The Controller has two keyhole cutouts on the back of its enclosure. A mounting template is provided
on page 14 of this manual. To mount, screw two appropriate fasteners into the mounting surface at
the desired location as shown below. Tighten until the bottom of the screw heads are 1/8" off the
mounting surface. Position the Controller cutouts over the screw and slide the unit downward. You
may have to tighten or loosen the screws slightly to fully engage the screw heads to get a snug fit.
