Opening & Closing the Flame Arrestor Assembly
REMINDER: Never remove the flame arrestor unless instructed to by LDARtools Technical Support
within the context of a support case. Damage to the glow disk is likely if not certain.
Replacing the Battery
1. Report an Issue. Failure to do so voids warranty.
2. Wait to be instructed by LDARtools Technical Support to change the battery (LDAR# 42200).
3. Place the phx42 in Sleep Mode.
4. Remove the phx42 lid.
5. Power down the phx42.
6. Identify the three battery connectors.
7. Hold the connectors, and then carefully disconnect each one from the battery.
8. If tabs are present, use them to lift the battery out of the enclosure.
9. Return the battery to LDARtools.
10. Reverse steps to install new battery.
11. Close Reported Issue by entering new battery serial number in customer portal.
REMINDER: Do not use any battery other than the one sold by LDARtools. The battery is made and
certified for the phx42.
Replacing the Pumps
As with any other repair on a phx42, you must first Report an Issue. Failure to do this will void the warranty,
if any. When you are instructed by the Tech Support staff to replace the pump, follow this procedure:
REMINDER: Before you replace a pump, confirm that there is no contamination in the probe / sample
delivery system. The contamination that ruined the last pump, could ruin the new pump if not removed.
Contamination will always require an RMA.
1. Remove the phx42 enclosure lid.
2. Put the phx42 into “Sleep Mode”.
3. Cut the center of the Teflon tubing to remove the pump (2 on the Sample Pump, 1 on the
Combustion Pump).
4. Remove the pump from the mounting clip.
5. Gently follow the wire to the connector.
6. Unplug the connector, pulling from both sides of the connector (not the wire).
7. Remove the remaining Teflon tubing from the push-to-connect fitting.
8. Insert the new pump into the push-to-connect fitting.
9. Plug in the electrical connection.
