GENERAL DESCRIPTION
The RD99 is an advanced technology refrigerant gas leak detector. This
detector is capable of locating any of the current halogen based gases
such as refrigerants. These gases include CFCs, HCFCs and HFCs.
A partial list of these gases include:
CFCs - R11, R12, R13 etc
HCFCs - R22, R502, R500 etc
HFCs - R134A, R123, R125, R33 etc
This unit will detect other halogen compounds such as SF6,
Perchlorethylene and Halon.
Please contact your distributor or Kane International Ltd for more
information on a specific application.
This instrument is not to be used in combustible environments.

OPERATION
BASIC OPERATION
1. Turn the instrument ON by sliding the High/Low/OFF switch to either
LOW or HIGH in a non-contaminated environment i.e. Fresh air
2. The power light will be illuminated green when the unit is turned on.
If the batteries are too low to operate the instrument this light will be
RED.
3. The instrument can be switched off at any time by moving the switch
to OFF. It is advisable to turn off in fresh air.
4. If the tip of the sensor becomes wet shake off excess and allow to
dry naturally.
LOW SENSITIVITY MODE
With the switch set to LOW:
5. The LED array will cycle from green to yellow, and then red
indicating the instrument is performing an auto-zero.
6. Once the auto-zero is complete the green LED will settle to a steady
2 second flash rate accompanied by a “bip”. This indicates the
instrument is ready for use.
7. To pinpoint a leak source, move the sensor tip along the area to be
checked. The tick rate will increase as you approach a leak and the
green LED will flash faster. As concentration of gas increases the
LED array will progressively move from flashing yellow, orange and
red (highest).
8. The tick rate will decrease and the lights will go out when you move
away from the leak source.

6
HIGH SENSITIVITY MODE
To pinpoint the leak or find a very small leak:
9. Set the instrument to HIGH sensitivity using the slide switch, when
switching from LOW to HIGH sensitivity the top red LED will flash
once.
10. Operation is as in low sensitivity mode but is more sensitive to small
changes in concentration.
11. Move the tip to levels of higher concentration indicated by an
increase in tick rate and more lights on the LED array. If the LED
array displays continuously flashing red, turn the switch to Low
Sensitivity and continue.
RESETTING ZERO
12. In fresh air the green LED should settle to a 2 second flash rate
accompanied by a blip sound.
13. To reset zero in fresh air, turn off the unit for about 2 seconds then
turn on in either LOW or HIGH sensitivity mode.

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 detector 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 all readings are as expected. (A level of disturbance in
the readings 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 (Feb 1999) Kane International Ltd is not
aware of any field based situation where such interference has ever
occurred and this advice is only given to satisfy the requirements of the
Directive.

BATTERY REPLACEMENT
1. Remove the battery cover on the back of the instrument.
2. Replace the 9 volt battery. A lithium or alkaline battery should
always be used. Ensure the terminals on the battery are the correct
polarity.
3. Replace the battery cover ensuring it is clicked home and locked in
place.
SENSOR REPLACEMENT
If the tick rate becomes uncontrollable, it may be necessary to change
the sensor.
We recommend that the sensor should be replaced at least once a year.
To remove the sensor:
1. Turn the unit off and remove the battery.
2. Unscrew the sensor anti-clockwise from the gooseneck.
3. Replace with new sensor by turning the sensor clockwise until finger
tight.
WARNING!
Turn the unit off and remove the battery before cleaning or replacing
sensor. Failure to do so may result in mild electrical shock or damage to
the instrument.
