Tracer TP-9361 PRO-Chek CO2 AM08043 - Manual (Page 7)

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-Chek CO2’s 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 800 hours.
The PRO-Chek CO2 will fl ash all the 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. Pull the IR cell straight out by grasping both edges of the label and
pulling evenly.
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.
