Start-up Guide
Intended Use
The phx42 analyzer can be used to safely collect data in Class 1, Division 1
hazardous locations. This includes:
• Refineries & Chemical plants
• Gas or oil pipelines
• Compressor and pump stations
• Oil field production facilities
• Anywhere VOCs are present
• Indoor and outdoor environments
The phx42 must be installed in a backpack while in hazardous locations.
• The phx42 should be upright in the pack with the north end (with probe port)
facing up.
• The phx42 must not share a pocket with any other items or tools.
• Backpack should fit snugly so the phx42 does not tilt away from the tech or tip
over. This can cause probe kinks.
Overnight equipment storage and calibration should be done indoors at or near room
ambient conditions (15-25 °C or 59-77 °F) with a maximum humidity of 85%.

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.
FAQ
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.

Power Button Indicators
Device is powered on.
Device is powered off.
The light pattern provides an indication of the machine’s state so that you can give commands using
the power button.
*Once the battery is fully charged, but connected to a charger then it will cycle between OFF/ON/OFF/ON
and Breathing. This is because once the battery is fully charged it stops charging (even though it is still
plugged in) and the light goes OFF/ON/OFF/ON until the battery is depleted a minimal amount and the
charging process re-begins and the light starts to Breath.

Filling the phx42 with Hydrogen
Gases are typically stored under pressure in metal cylinders. Cylinders are designed to withstand high
pressures. Improper handling and use of compressed gases can result in devastating consequences. Be
sure to follow all safety guidelines outlined by your facility.
1. Remove the H2 quick-fill cover (LDAR#42908).
2. Make sure of the following:
(a) The hydrogen cylinder being used to fill the phx42 has a regulator in place.
(b) Turn the regulator to counter-clockwise if pressure has been bled.
(c) Verify that there is no dust or debris in the Hydrogen (H2) fill port.
(d) Verify that there is no dust or debris in the Hydrogen (H2) fill adapter.
(e) Verify the arrow on red handle is pointing to the
breather side of the fill valve.
(f) Gauge nearest the cylinder is reading ~1800 psi. If
not, adjust regulator.
(g) If pressure has bled off the fill adapter, turn the red
handle 180 degrees for 2 seconds to bleed any air
from the system before connecting to the phx42.
3. Power on the phx42. Sleep mode, connected, disconnected, or ignited are all ok. In some
cases, a flameout will occur. This is normal.
4. Connect the H2 fill adapter to the H2 fill port, then verify the connection by slightly
pulling on the 3-way valve.
5. Confirm that the H2 fill adapter is firmly seated on the H2 fill port.
6. Turn the red handle 180° to open valve. Arrow should point to the fill hose.
7. Wait for 10 seconds after the needle on the gauge stops moving.
8. Turn the handle back 180° to close valve.
There will be a slight hiss from the release of pressure.
9. Pull on the collar of the H2 fill adapter to release it.
10. Twist the H2 quick-fill cover onto the H2 fill port.
11. Close bottle. There is no need to bleed pressure off the H2 fill Adapter.

11
REMINDER: The phx42 MUST have the H2 quick-fill cover in place at all times unless filling.
A very small amount of O-ring grease should be applied to the phx42 side of the quick connect
weekly. Apply as little as possible.
Your phx42 is now filled with hydrogen, and while it has been designed to minimize
possible leaks, you should handle and store it with caution.
TECH TIPS:
1. Maintain a constant pressure range of 400 – 1800 psi. If the hydrogen is allowed to drop
below 400 psi, you may have to follow the “Receiving After Shipping” procedure below.
2. Fill your cylinder at end-of-day, this accomplishes several things:
a. Analyzer will have enough hydrogen for end of day drift.
b. Being full overnight allows the calibrating tech to see if the pressure is stable or
dropping (leak test).
c. Motor needle valve has time to stabilize with a full cylinder.
3. Many successful users have adopted a 2-fill practice: Mid-day and End of day.
4. If the H2 Quick Fill Cover pops off, it’s likely that there’s a hydrogen leak. Report an issue to
LDARtools Technical Support and send the Log files.
Receiving After Shipping
The battery and the hydrogen cylinder are drained for shipping. Special charging and fill procedures are
required.
Charge the battery:
1. PULL Charging Port Cover (LDAR# 42013) to access the charging port. Twisting/turning the
Cover to remove will damage the Tether. It does “click” into the Charging Port so some effort
will be required to remove the Charging Port Cover.
2. Align the red lines on the phx42 charger and the charger jack. Push gently and you will feel a
click.
3. Turn on phx42, if not already on. The power button should have a light on*.
4. If the pumps are still running, tap the power button four times to put the machine in Sleep
Mode.
If battery power is sufficient, power light on the phx42 will begin to breathe/pulse.
*REMINDER: If charging a phx42 with a fully depleted battery, the power button may blink rapidly or
not respond at all. Leave the phx42 powered off for a minimum of 90 minutes while connected to charger.
Then repeat steps 3 and 4.

12
Filling Empty cylinder with Hydrogen
The motor needle valve for the hydrogen cylinder will need some time to adjust from an empty to a
full cylinder. Follow the standard “Filling the phx42 with Hydrogen” procedure, with the following
exceptions:
• After step 6 (in the fill procedure above) instead of counting to 10, watch the gauge near the
hydrogen fill cylinder and stop the flow when the gauge is reading between 900 – 1000 psi.
Turn the handle back 180° to close valve.
• Pull on the collar of the H2 fill adapter to release it.
• Wait 4 minutes for the motor needle valve to adjust.
• Confirm that the H2 fill adapter is firmly seated on the H2 fill port.
• Turn the red handle 180° to open valve. Arrow should point to the fill hose.
• Wait for 10 seconds after the needle on the gauge stops moving (at 1800 psi).
• Turn the handle back 180° to close valve.
o There will be a slight hiss from the release of pressure.
• Pull on the collar of the H2 fill adapter to release it.
• Twist the H2 quick-fill cover onto the H2 fill port.
• Close bottle. There is no need to bleed pressure off the H2 fill Adapter.
TECH TIP: 2-3 ignition attempts may be required. Pressure Stabilization messages are normal. Wait 4
minutes between each ignition attempt. If Ignition Failure continues, perform a self-check, and submit a
failure with comments to LDARtools Support Team.

13
Charging the phx42
1. PULL Charging Port Cover (LDAR# 42013) to access the charging port. Twisting/turning the
Cover to remove will damage the tether. It does “click” into the charging port so some effort will be
required to remove the Cover.
TECH TIP: It is important to grasp the cable between the Cover and the crimp when
removing the charging port cover. This accomplishes two things:
• Protects the cable crimp.
• Ensures that you're pulling the Cover out straight instead of at an angle.
2. Align the red lines on the phx42 charger and the charger jack. Push gently and you will feel a click.
3. Turn on phx42, if not already on. The power button should have a light on*. If the pumps are still
running, tap the power button four times to put the machine in Sleep Mode.
*If battery power is sufficient, power light on the phx42 will begin to breathe/pulse.
TECH TIP: It is best to leave the charger connected during calibrations (daily, PreCal, or drift) for best
battery performance.
REMINDERS:
1. The Charging Port Cover MUST be in place while using the phx42 in a hazardous area.
2. If charging a phx42 with a fully depleted battery, the power button may blink rapidly or not respond
at all. Leave the phx42 powered off for a minimum of 90 minutes while connected to charger. Then
repeat step 3.
Replacing the Probe Tip Filter
REMINDERS:
1. A probe tip filter should be in place at ALL times while the phx42 pump(s) are running.
When prompted to change the filter by the handheld or before unit start up:
1. Remove the dirty filter, and then attach the probe tip to a clean filter. Probe Filter-Double
Thread (LDAR# 25).
2. Re-ignite.
