OPERATING GUIDE:
1. The refrigerant leak detector unit is not equipped with anti-explosive
designs and measures. Do not use this unit in the environment with any
burnable gases
2. There are some environmental conditions that might cause error
readings:
• Pollutant places
• Large temperature variation
• Places with high wind velocity
• Organic solvent, adhesive vapor, fuel gas and vesicant will cause an
abnormal response from the sensor. Try to avoid environments affected
by these substances
• Places filled with too much Freon gas

LED LEAK INDICATOR DEFINITION:
GETTING STARTED:
INSTALLING BATTERIES
• Loosen the screw and remove the battery compartment door located on
the bottom of the instrument as shown below (Fig.1).
• Install 4 “AA” batteries.
• Reinstall the battery cover by aligning it with the handle.
When the batteries are nearing the end of their useful life, the Red LED Low
Battery indicator will illuminate. The batteries should be replaced as quickly
as possible.

AUTOMATIC AMBIENT RESET FEATURE:
The Refrigerant leak detector features an Automatic Ambient Reset function
that sets the unit to ignore ambient concentrations of refrigerant.
• Automatic Ambient Setup - Upon initial power on, the unit automatically
sets itself to ignore the level of refrigerant present at the tip. Only a
level, or concentration greater than this will cause an alarm.
CAUTION!
Be aware that this feature will cause the unit to ignore any refrigerant
present at turn on. In other words, with the unit off if you place the tip up to a
known leak and switch the unit on, no leak will be indicated!
• Ambient Reset Feature - Resetting the unit during operation performs a
similar function, it programs the circuit to ignore the level of refrigerant
present at the tip. This allows the user to “home-in” on the source of the
leak (higher concentration). Similarly, the unit can be moved to fresh air
and reset for maximum sensitivity. Resetting the unit with no refrigerant
present (fresh air) causes any level above zero to be detected.
• After the unit is warmed up, the default sensitivity level is set at “High”
and Auto Reset function is “ON”.
• Auto Reset function is best used initially when user is moving around
trying to identify leakage source. Once the leak source is determined,
cancel the Auto Detect function to proceed with leakage measurement.
• Auto Reset function should be turned OFF when use in fixed position
leakage detection.
FEATURE SENSITIVITY ADJUSTMENT:
The instrument provides two levels of sensitivity. When the unit is switched
on, it is set to the high sensitivity level.
• To change the sensitivity, press the “Lo” key. When this key is pressed,
the visual display will momentarily show the two left LED’s (green)
indicating low sensitivity level is selected.
• To switch back to high sensitivity, press the “Hi” key. The two right LED’s
(red) will light momentarily indicating high sensitivity level is selected.

OPERATING PROCEDURE:
WARNING!
Do not operate this instrument in the presence of gasoline, natural gas,
propane, or in other combustible atmospheres.
• HOW TO FIND LEAKS
NOTE: A sudden whipping of the leak detector probe or “blowing” into the
sensor tip will affect the air flow over the sensor and cause the
instrument to alarm.
(1) POWER-UP KEY:
The “ON/OFF” key turns the Refrigerant Leak Detector instrument ON or OFF
and is also the reset function.
• Press it once to turn on the Refrigerant Leak Detector. The display will
illuminate with flashing for 45 seconds to heat up the sensor.
• Press and hold this button for 5 seconds to turn OFF the power.
(2) AUTO RESET & RESET FUNCTION KEY
When the Auto Reset function is turned ON, the meter will monitor
background status and fine tune itself. When Reset LED light is on, it
indicates it is in ON mode. Press Reset button and hold for 2 seconds the
Reset light will turn off and Auto Reset function is in OFF mode. When the
Reset light is off,it indicates the Reset function is in manual mode. Press the
Reset button once to enable manual Reset function.
(3) VERIFY THE CONDITION OF THE UNIT AND SENSOR:
• Set the sensitivity level to “Hi”.
• Open the Leak Check bottle cover and slowly move it closer to the
flexible stainless probe nozzle.
• The indication should move up to high from low. Then move the check
bottle away and the LED should go off again. This shows that the unit is
in working condition.
• If the unit does not perform as expected, order a new sensor and
batteries from your local supply office.
(4) ENTER THE MEASURING MODE:
• Place the tip of the leak detector probe as close as possible to the site
of the suspected leak. Try to position the probe within 1/4"
(6mm) of the possible leak source.
• Slowly move the probe past each possible leakage point.
• When the instrument detects a leak source, the audible tone will alarm.
Additionally, the visual indicators will light from left to right, Green LED,
then Orange LED, then Red LED (highest concentration) as increase in
level indicates that the location is close to the source.
RLD382P Manual -6P-071008:RLD382P 7/10/08 11:32 AM Page 6
• When the instrument signals a leakage, pull the probe away from the
leak for a moment, then bring it back to pinpoint the location. If the
refrigerant leak is large, setting the sensitivity switch to “Lo” will make
it easier to find the exact site of the leak.
• Return the sensitivity switch to “Hi” before searching for additional
leaks.
• When you've finished leak-testing, turn OFF the instrument and store it
in a clean place to protect the leak detector from possible damage.
REPLACING A NEW SENSOR:
Under normal operation, the sensor should work for more than one year.
Though, the sensor may experience a limited operative period. Exposing the
sensor to high densities of coolant (>30000ppm) will shorten its life cycle
rapidly. It is important to ensure that the sensor surface is free from water
droplets, vapor, oil, grease, dust and any or all other forms of contaminant.
Furthermore, to ensure good working condition of the unit, a sensor must be
replaced periodically when it’s operative life is over.
WARNING! When replacing a new sensor, the worn-out sensor may be HOT!
(1) Remove cone cap cover from the tip of flexible probe.
(2) Pull out the old sensor and insert the new sensor into the plug
(see below fig. 2).
(3) Seal the cap cover over the plug.
CLEANING:
The instruments plastic housing can be cleaned with standard household
detergent or isopropyl alcohol. Care should be taken to prevent the cleaner
from entering the instrument. Gasoline and other solvents may damage the
plastic and should be avoided.
WARNING!
Detergent or isopropyl alcohol may damage the sensor. Please avoid contact
with the sensor at all times.
