Combustible Gas Leak
Detector

INTRODUCTION
Please read these instructions fully before using the GLD/450PLUSplus.
The GLD/450plus is powered by two AA batteries. Take care to ensure
the batteries are inserted correctly. When replacing batteries please
dispose of used batteries in accordance with local regulations.
The GLD/450plus will enable the operator to pin-point small
combustible gas leaks. It does not MEASURE gas levels
Do not use the GLD/450plus as a personal safety monitor.
Take extreme care when using the GLD/450plus, especially when gas is
detected. If in any doubt, open doors and windows to ventilate rooms
under test, ensure people are not at risk and call the Emergency Service
Provider.
The leak detector operation:
Warm up:
Switch the GLD/450plus ON in fresh air, (push the slide switch away
from you). All 3 LEDs will briefly illuminate and the unit will bleep for
approximately 1 second.
The LEDs will then cycle for approximately 20 seconds to indicate the
warm-up / reset period as the sensor stabilises.
When the warm up / reset period is complete all 3 LEDs will briefly
illuminate and the unit will bleep for approximately 1 second.
Normal operation:
The Green LED will remain illuminated if the batteries have sufficient
power to run the GLD/450plus. If the Green LED is not illuminated the
batteries in the KANE425/450 must be replaced.
In fresh air the unit will bleep about twice a second and the Yellow LED
will also flash.
If gas is detected the rate of bleeping and Yellow LED flashing will
increase.
The Red LED will illuminate at higher levels of gas and the bleep rate will
increase to become almost continuous.

To pin-point a gas leak:
After completing the warm up period in fresh air, move the tip of the
GLD/450plus’s “wand” towards the suspected gas leak. The rate of
bleeping and LED flashing will increase as the concentration of the gas
increases, thereby leading you to the gas leak.
If the Red LED is illuminated and the bleeping is continuous before you
have pin-pointed the gas leak, you must reset the GLD/450plus in this
concentration of gas. To do this switch the GLD/450plus OFF, then back
ON and wait for 20 seconds to allow the sensor to reset itself in this
concentration of gas. You can then continue to pin-point the gas leak.
Tips:
If the initial bleep rate does not settle to about twice a second, switch off
and back on to allow additional re-setting time.
The unit may be reset at any time by switching off and back on.
The unit will detect methane and most other "HC" gases down to low
ppm levels.
The unit will respond to some leak detection fluids. Use the
GLD/450plus first!
The unit is intended for use in sheltered areas or indoors as severe
draughts may cause (temporary) false indication.
Avoid contamination by water or dirt and do not allow any reactive
chemicals etc. to come in to contact with the sensor.

ELECTROMAGNETIC COMPATIBILITY
The European Council Directive 89/336/EEC requires that electronic equipment does
not generate electromagnetic disturbances that exceed defined levels and has an
adequate level of immunity to enable it to be operated as intended. The specific
standards applicable to this product are detailed in the appendices.
Since there are many electrical products in use that pre-date this Directive and may
emit electromagnetic radiation in excess of the standards defined in the Directive
there may be occasions where it would be appropriate to check the analyser prior to
use. The following procedure should be adopted:
•Go through the normal start up sequence in the location where the equipment is to
be used.
•Switch on all localised electrical equipment that might be capable of causing
interference.
•Check that performance is as expected. (A level of disturbance in the
performance is acceptable). If not adjust the position of the instrument to minimise
interference or switch off, if possible, the offending equipment for the duration of
the test.
At the time of writing this manual (December 2006) there is no awareness of any field
based situation where such interference has ever occurred and this advice is only
given to satisfy the requirements of the Directive.
