Battery Installation
1. See Figure 2. Using a #1 Phillips screwdriver,
fi
rst loosen the battery
door screw located at the rear of the detector; then remove the door.
2. Install four ‘AA’ alkaline batteries into the detector, observing the
polarity markings that are molded on the side of the case.
3. Reinstall the battery door and tighten its screw.
Turning the Detector ON / OFF
See Figure 3. The detector is toggled ON and OFF by pressing the
POWER
button.
When
fi
rst turned on, observe that the Power LED glows and that all
other LED’s are tested by being turned on for 1 second.
The detector requires 10 seconds to warm up. After which time all LED’s
should be off except for the Power LED, along with the probe tip blinking
and audible indicator ticking at approximately once-per-second.
Note that during the warm-up period, the detector has zeroed out any
background concentration of vapors or refrigerant that may have been
present in the area.
After the detector is turned on and allowed to warm up, it is ready to per-
form leak testing as described in Section
Procedure for Locating a Refrig-
erant Leak.
