Caution: To avoid damage to your unit or incorrect fitting, take account of the following
cautions:
1) The mini Opal is designed for mounting vertically on a flat surface. Do not mount it
on the underside of a roof edge because the sensor cannot be angled correctly in this
orientation.
2) The range and focus of the mini Opal can be affected by grease on the lens or sensor.
Always hold the lens by the edges and do not touch the sensor. If touched, clean
with an appropriate isopropyl-alcohol based cleaning agent and a soft, lint-free
cloth.
3) Do not install your mini Opal outside during wet conditions such as rain or mist.
Moisture inside the case can cause faults. The moisture will remain in the air-tight
enclosure indefinitely.
Mount
1) Choose a mounting position, it should:
Be 60cm (2ft) from lamps
If possible, allow the wiring to be run through the wall
Be smooth enough to hold the tamper plate in position and provide a good seal
against the expanded foam back plate
Make allowance for obstacles that may cause a varying thermal image. For
example, trees or shrubs in a wind, ripples on ponds (or large puddles), boiler
flues and animals
2) Using a 3mm hex key to loosen the hex screw and remove the cover.
3) To reveal the two cable access, unscrew the top, plastic wing-nut and, remove the
circuit board and lens unit.
4) The cable entry holes are protected by two sealed grommets. Use a screwdriver to
punch out the centre of the grommet(s) you intend using.
5) Hold the unit to the mounting surface and, mark the location of mounting and
cabling holes.
WARNING: To prevent injury or damage to the unit, do not drill through the holes
in the back of the case.
