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.
