attach the sensor at the same place by means of clips or adhesive tape, using
appropriate thermal insulation against environmental influences.

Sensor cable extension:
Sensor cables (22/4 AWG telephone cable) can
be extended up to 150 ft. A connection between the sensor and extension can be
established as follows:
Cut supplied heat shrinkable tubing to desired length (about ½ ”). Slide tubing
over one end of wire to be sliced after removing enough outer insulation to
accept the tubing. Then splice wire and slide tubing over the splice. Heat gently
all around until tubing shrinks tight.
Slide larger tubing (about ¾ “) over the entire completed splice. Heat gently all
around until tubing shrinks tight. This connection can then be drawn gently into
the pipe work. You need only two wires for sensor cable; the other two wires are
spare wires.
Caution:
Do not overheat tubing! Remove heat as soon as tubing shrinks tight,
as material will continue to shrink. With flame source, use even back and forth
motion all around tubing. A heat gun may be used, if available. Let tubing cool
for maximum strength.
ontroller unit installation:
For viewing comfort, the controller unit
should be positioned at eye level. It is always good practice to keep
electronic equipment away from cold, and heat, as extremes of temperature may
reduce the lifetime of the device. It is also good practice to keep electronic
equipment away from heavy electrical loads, switches or contactors as these
may cause electrical and electromagnetic interference when switched on or off.
