Introduction

The 16600 is an electronic leak detector used to detect refrigerant leaks in air

conditioning and refrigeration systems. It features a sensitivity selection switch

which allows it to be used with CFCs and HCFCs at one setting and HFCs at

the other. The unit is able to detect leaks smaller than 1/2 ounce per year.

Other features include audible and visual leak indicators, a volume control, a

threshold balancing control and a 16" gooseneck probe, which holds its

position for one-handed operations. When the unit is not being used, the probe

wraps into a retaining clip on the back of the case.

to meet SAE J-1627 (1993)

for R-12 and R-134a refrigerants.

Description

Controls and Indicators

ON/OFF and BALANCE—The same control turns on the unit and gives you

infinite control for eliminating background contamination to find leaks fast.

VOLUME—Allows you to adjust the audible leak signal to the appropriate

volume for the working conditions.

SENSITIVITY LEVEL—The 16600 can be used for a wide range of

refrigerants, but because of different properties of the refrigerant, the correct

sensitivity level should be selected. Here are guidelines:

• Level 1—HFCs such as R-134a, HP 62, AC 9000, AZ 20, and AZ 50

(refrigerant blends made up primarily of HFCs)

• Level 2—CFCs and HCFCs such as R-12, R-22, R-500, and R-502

(refrigerant blends made up primarily of CFCs and HCFCs).

If you are not sure which refrigerant is in the system, start with Level 2 and

change to Level 1 if you have trouble pinpointing the leak after balancing the

leak detector several times.

VISUAL LEAK INDICATOR—The LEDs light up to show increasing levels

of concentration. One LED means a minimal amount of refrigerant is reaching

the sensor; when all LEDs are lit, there is a sizeable leak or concentration. The

LEDs illuminate in sequence from bottom to top.

LOW BATTERY INDICATOR—If only the top LED is lighted, the batteries

are low and should be replaced.

AUDIBLE LEAK INDICATOR—The normal operating sound is a steady

ticking. As you move the probe closer to a leak, the tone will change to a faster

ticking sound and then to an alarm sound (the loudness of this indicator can be

adjusted using the volume control).

WARNING

Wear safety goggles when working with refrigerants.

Contact with refrigerants can cause eye injury.

One-Hand Operation—

The 16" gooseneck probe

holds its position, so you

can operate the detector

with one hand.

Audible and Visual Leak

Indicators—An alarm increases

in frequency as the tip nears a

high concentration of refrigerant.

LEDs light up to indicate a leak

and refrigerant concentration.

Volume Control—Adjust

the audible signal to the

volume that’s right for the

background noise in the

shop or at the job site.

Threshold Balancing

Control—Gives you infinite

control for eliminating

background contamination,

so you can zero in on the

leak site.

Battery Door—Located

on the back side of the

handle, the door is easy

to remove to change

batteries.

Sensing Selection Switch—

Slide the switch to Level 1 or

Level 2, depending on the

type of refrigerant in the

system.

Features

The first time you use the 16600 leak detector, install the batteries before

turning on the unit. Four “AA” alkaline batteries are included (see

“Maintenance Instructions”).

1. Remove the gooseneck probe from the retaining clip on the back of the leak

detector case.

2. Turn the ON/OFF switch to ON.

3. Select the sensitivity level by sliding the switch to either the “1” setting or

the “2” setting.

4. Adjust the balance. Turn the BALANCE control up to a loud alarm sound,

then turn it down until you hear a slow, steady ticking.

5. Begin searching for the leak. The recommended scan rate is two (2) inches

per second with the sensing tip as close as possible to the area being

searched. Run the probe under tubing and check carefully around bends,

fittings, and other typical leak points.

TIP: Refrigerant is heavier than air, so check for leaks at the top of the system

first, working your way toward the bottom. In strong wind conditions, you may

need to shield the area before searching for leaks.

6. To pinpoint a leak, you may need to adjust the balance. When you are near a

concentration of refrigerant, the alarm tone will sound. Keep the probe in

the same position and turn the balance control down until you hear the

ticking sound. Then continue searching for the leak. You may need to

balance the unit several times if there is a large leak and refrigerant has

accumulated.

7. If you find more than one leak, or if you suspect more than one, repair the

larger leak(s) first so pinpointing the smaller leak is easier.

Maintenance

Cleaning/Replacing the Sensing

Tip

The sensing tip is the most critical component of the leak detector.

Periodically it may become clogged with dirt, grease, and oil. If the tip looks

dirty, and you have difficulty pinpointing a leak or experience constant false

alarms, the tip probably needs to be cleaned or replaced.

To Clean the Tip:

1. Turn the ON/OFF switch to OFF.

2. Unscrew the tip from the gooseneck probe.

3. The tip can be cleaned in most vaporizable solvents, such as denatured

alcohol. We recommend using a solvent, but if this is not possible, wash

the tip in warm, soapy water. Rinse thoroughly with clear water and allow

to air dry completely before reinstalling the tip on the probe.

IMPORTANT! Allow adequate time for the tip to air-dry before using

the leak detector. Moisture in the tip can trigger false alarms.

Be sure your hands are clean and dry. Be careful not to contaminate

the tip with perspiration, grease, hand cleaners, etc.

Maintenance

To Change the Tip:

An extra tip comes with the unit. You can also buy replacement tips. One extra

tip stores in a special slot inside the battery compartment. Follow the

instructions in “INSTALLING/REPLACING BATTERIES” to open the battery

compartment.

1. Turn the ON/OFF switch to OFF.

2. Unscrew the tip from the gooseneck probe.

3. Thread the new tip onto the probe until it’s finger-tight. Do not overtighten.

4. When the leak detector is not in use, wrap the gooseneck probe into the

retaining clip to protect it.

Installing/Replacing Batteries

Your unit uses four (4) “AA” alkaline batteries. The batteries should be replaced

if the top LED (beside the words LOW BATTERY) lights up when the unit is

first turned on. The battery compartment is located on the back of the case.

1. Turn the ON/OFF switch to OFF.

2. Remove the screw holding the battery compartment door. If you are

replacing batteries, remove the old batteries.

3. Place the new batteries in the battery compartment, following polarity

indication.

4. Replace the battery compartment door, and secure the door with the screw.
