cartridge, as it can be damaged when handled. Slide a new filter cartridge into the cap. Twist the cap with the
new filter cartridge onto the probe base until it is tight.
NOTE: It is very important that you operate the PRO-Alert 2791 with a filter cartridge installed at all times.
Failure to do so could damage the leak detector’s components.
Changing the Infrared Cell
WARNING
COMPONENTS MAY BE HOT. TURN OFF DETECTOR AND DISCONNECT POWER ADAPTER CORD
BEFORE REMOVING THE INFRARED CELL DOOR.
The PRO-Alert 2791 infrared (IR) cell is located in the body of the detector. The IR cell is a complete assembly
consisting of a metal tube, connectors and electronic components. The IR cell is not designed to be taken
apart. Doing so will destroy the cell. This specialized IR cell will operate for about 1,000 hours.
The PRO-Alert 2791 will flash all the yellow leak indicators when the IR cell has reached the end of its useful
life. To replace the IR cell:
1. Locate the latch for the IR cell door on the top cover at the rear of the detector.
2. Using a small screwdriver, pull the latch forward and remove the door.
3. Grasp the IR cell according to the directions printed on its label. Pull it straight out so both ends are
released at the same time.
4. Remove the replacement IR cell from the protective package.
5. Carefully align the male leads and air tubes on the IR cell with the connectors mounted on the circuit board.
Insert the leads into the sockets and push the IR cell straight down.
NOTE: Ensure the lead connectors on the IR cell ends are not bent and the cell is seated tightly.
Removing/Replacing the Power Stick
The PRO-Alert 2791 uses a preassembled power stick.
Remove the battery compartment door on the back of the PRO-Alert 2791 by pressing on both release
buttons on the grip and pulling the door straight out. The power stick is connected to the circuit board via a
miniature electrical connector. Disengage the connector and slide the power stick out of the PRO-Alert 2791.
Slide the new stick into the PRO-Alert 2791 and push the miniature connector on the power stick into the
mating half on the circuit board. Do not bend the circuit board’s connector away from the board. Once the
power stick is in place, close the battery compartment by aligning the two tabs and sliding the door straight in
until it latches. Ensure the wire leads on the power stick are not pinched in the door. Allow 10 hours to fully
charge the new power stick.
