Operating Instructions

Note: There are some environmental conditions that might cause an inaccurate reading: high pollutant environments, large temperature variations, high wind velocity and environments with large amounts of freon gasses. Organic solvents, adhesive vapors, fuel gasses and vesicants will cause an abnormal response from the sensor. Avoid these environments.

Fast movement of the sensor probe or blowing into the sensor tip will affect the air ow over the sensor and cause the unit to alarm.

Power-Up & Reset

ONON

The

button turns this refrigerant leak detector instrument ON, OFF and serves as an ambient concentration reset button (see ambient concentration reset for more information).

Press indicators will then illuminate. Please take note, you have to wait for 1.5 minutes to heat up the sensor for proper functionality.

Press

Press and hold inactive for 10 minutes it will automatically turn off.

Testing the Unit

Turn the unit ON and set the sensitivity level to “Hi”. Open the cover to the leak-check bottle and slowly move it closer to sensor tip. If the unit is in working condition the LED leak indicators will light up, from low to high. Repeat this process to conrm that the closeness of the leak-check bottle results in the leak indicators to uctuate from low to high. If the unit does not perform as stated you must send your unit in for maintenance. For service on this or any other REED product, contact REED Instruments at info@reedinstruments.com.

Measuring

Position the tip of the sensor probe within 1/4 inch (6 mm) of the suspected leak source. Slowly move the sensor probe past each possible leakage point. When the unit detects a leak source an audible tone will sound and visual indicators will light on the LED leak indicator display, appearing from left to right; green to orange to red (red being the highest concentration, green the lowest). Increasing levels indicates the proximity of the leak location is getting closer. When the unit signals a leakage, pull the probe away from the leak for a moment and then bring it back slowly to pinpoint the location. If the refrigerant leak is large setting the sensitivity switch to LOW (see sensitivity adjustment) will make it easier to nd the exact site of the leak. Return the sensitivity switch to HIGH before searching for any additional leaks. When you’ve nished testing for leaks turn the unit OFF and store it in a cool, dry, clean place to protect the sensor and unit from any possible damage.

Ambient Concentration Reset

This combustible leak detector features an ambient concentration reset function that sets the unit sensors to ignore the ambient concentrations of refrigerant present.

Automatic Ambient Setup When turned ON the unit’s sensor will set itself to ignore the level of refrigerant present at the tip. Only a level or concentration great than this will cause the unit to alarm.

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 of the sensor. 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.

Note: Be aware that this feature will cause the unit to ignore any

that high sensitivity has been selected.

Sensor Replacement

To ensure the accuracy of the unit, the sensor must be replaced periodically. This unit’s sensor has a limited operative period and under normal operation it should stay operative for over a year. To prolong the sensor’s life-cycle ensure that the sensor’s surface is free from water droplets, vapor, oil, grease, dust and any other form of contaminant as well as any exposure to high density coolants (>30000ppm).

WARNING

When replacing the sensor, the old sensor may be very HOT.

1. Remove the sensor protector cover from the tip of the sensor probe

2. Pull out the old sensor and insert the new sensor into the plug (see below)

3. Place the sensor protector over the new sensor

Cleaning

This plastic housing can be cleaned with isopropyl alcohol or standard household detergents. Do not allow any cleaner to enter the unit or to come into contact with the sensor as it may cause damage. Gasoline and any other solvents may damage the plastic and should be avoided.

WARNING: The detergent or isopropyl alcohol could damage the sensor, be sure to keep them from the sensor when cleaning the unit.

Battery Replacement

Note: When the battery power is running low, the red LED low battery indicator will illuminate. The batteries should be replaced as quickly as possible.

1. Loosen the battery cover screw and remove the battery cover located on the bottom of the instrument as shown below.

2. Install 4 “AA” size alkaline batteries.

3. Replace battery cover by aligning it with the handle and sliding back onto the unit.

4. Tighten the battery cover screw so the battery cover is securely into place.
