Connecting the Probe
1. Align the quick disconnect (A), which is attached to probe hose (B),
with the probe port (C).
2. Snap the quick disconnect into the probe port.
REMINDER: The probe and a probe tip filter should be connected to the phx42 before
igniting the device (unless performing filter detection calibration).
Never operate the phx42 pumps without a filter in place. Do not remove the filter on a
running phx42.
Can I use an extension/other probe on the phx42?
Any device certified for use in hazardous environments using modern standards is done so
with accessories defined or attached. The phx42 was certified with the basic probe. You
should consult your safety department for a hazard assessment before using a different
probe.
Any extension should not exceed 20ft of tubing with minimum ID of 1/8”. The tubing in the
standard probe is 1/16” and cannot be used as a base for an extension probe. The extension
probe should utilize the same filters as the standard probe.
Why is the probe handle so heavy?
The probe handle was made from stainless steel to comply with the applicable safety
standards.
TECH TIP: When using the probe, a few basic points should be kept in mind while using it daily:
1. When moving from place to place and not actively using the probe for inspections, the probe
handle should be attached to the backpack so that it isn’t accidentally dropped.
2. When using the probe, pay attention to the probe hose and avoid snagging or pulling on it.
This can place undue stress on the connections and potentially cause a leak.
3. Be mindful of the probe filter and tip. Dropping the probe onto the filter or prying with the
probe tip can potentially break the filter and either lodge plastic in the fitting at the end of the
probe or cause leaks at the filter interface.
4. Never mar or scratch the center of the Leur lock fitting where the sealing is occurring. Doing
so will lead to leaks and repairs of the probe.
5. Make sure the phx42 is oriented in the backpack so that the probe connection is not pinched,
or kinked while being used.
