Operation

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.
