Personnel and Equipment Safety Information
This section describes important safety information to avoid personal injury
and damage to the equipment while installing, operating, maintaining, or
servicing the equipment. All safety regulations, standards, and procedures at
the analyzer location must be followed. All personnel involved with
installation, start-up, operation, maintenance, service, or troubleshooting of
the analyzer must review and follow these Warnings and Cautions.
Hazardous Locations Always disconnect mains AC power and/or alternate power
sources to the analyzer before opening any covers or doors on the analyzer to
check or perform maintenance on any components within the enclosures.
If it is necessary to open the analyzer’s covers or doors while the circuits
are live, test the area for flammable gases (and proceed only when the area is
safe). To work on the analyzer with it powered up and its electronics
enclosure(s) open, take appropriate precautions to avoid electrical shock.
Hazardous voltages are present inside.
Refer to the analyzer User Manual for additional warnings when working on the
analyzer and Heated Acid Gas Sample Probe.
Any adjustments or servicing of the analyzer while it is energized should be
performed only by properly trained and qualified personnel.
For hazardous areas, all covers must be tightly fastened with all screws or
latches while the circuits are live.
The Probe Heater Assembly is hot while it is powered up; take precautions to
avoid burning yourself.
If potentially flammable gases or vapors are present, do not open any covers
on the analyzer without first disconnecting mains AC power and/or alternate
power sources to the analyzer.
vi | Heated Acid Gas Sample Probe
PN 903-8663, Rev H
The Probe Heater Assembly is certified for use in hazardous classified areas
and is rated T3, which means that it will not produce surface temperatures
higher than 200 °C that could be an ignition source. This rating, however, is
based on the maximum temperature that can be achieved with energy supplied by
its electrical heater. An internal thermal switch disables the heater at 170
°C. In practice, this is the limiting factor, but those responsible for
installation and maintenance of the overall probe assembly must take other
factors into consideration.
Although the maximum process temperatures are stated as 210 °C (standard) and
450 °C (High Temperature version) these ratings apply to the probe and valve
assemblies. In normal installations, the low sample flow and aspirator
operation, combined with simple thermal losses, result in temperatures well
below the dewpoint of the sample, so the heater must be added. However, if
installed incorrectly, the use of external insulation and heat tracing could
theoretically combine with high process temperature and process radiation to
drive the surface of the heater assembly over 200 °C without any internal
electrical heating being applied. To ensure this is not the case, the user
must verify that the probe heater is being controlled at its set point and not
being influenced by the process temperature. If the analyzer indicates the
temperature is higher than the setpoint (greater than 170 °C), this indicates
a problem.
When working on the analyzer/Heated Acid Gas Sample Probe, all safety policies
and procedures for the hazardous area must be strictly followed. These
policies and procedures are specified by the Owner Company and the local
electrical inspection authority.
Any electrical connections, adjustments, or servicing of the analyzer/Heated
Acid Gas Sample Probe while it is energized or de-energized should be
performed only by properly trained and qualified personnel using materials and
methods specified and approved by the Owner Company and the local electrical
inspection authority.
For electrical-shock protection, the analyzer/Heated Acid Gas Sample Probe
must be operated from a grounded power source that has a securely connected
protective-ground contact.
Disconnect the power before removing any components from the analyzer or HAG
Probe.

Electromagnetic Compatibility (EMC)
Read and follow the recommendations in this section to avoid performance
variations or damage to the internal circuits of this equipment when installed
in harsh electrical environments.
The various configurations of analyzers that use Heated Acid Gas Sample
Probes, and ASR900 Heaters used on Heated Acid Gas Sample Probes, should not
produce, or fall victim to, electromagnetic disturbances as specified in the
European Union’s EMC Directive. Strict compliance to the EMC Directive
requires that certain installation techniques and wiring practices are used to
prevent or minimize erratic behavior of the Analyzer or its electronic
neighbors. Below are examples of the techniques and wiring practices to be
followed.
In meeting the EMC requirements, the various Analyzer configurations described
in this manual rely heavily on the use of metallic shielded cables used to
connect to the customer’s equipment and power. Foil and braid shielded I/O and
DC power cables are recommended for use in otherwise unprotected situations.
In addition, hard conduit, flexible conduit, and armor around non-shielded
wiring also provides excellent control of radio frequency disturbances.
However, use of these shielding techniques is effective only when the
shielding element is connected to the equipment chassis/ earth ground at both
ends of the cable run. This may cause ground loop problems in some cases.
These should be treated on a case-by-case basis. Disconnecting one shield
ground may not provide sufficient protection depending on the electronic
environment. Connecting one shield ground via a 0.1 microfarad ceramic
capacitor is a technique allowing high frequency shield bonding while avoiding
the AC-ground metal connection. In the case of shielded cables the drain wire
or braid connection must be kept short. A two-inch connection distance between
the shield’s end and the nearest grounded chassis point, ground bar or
terminal is highly recommended. An even greater degree of shield performance
can be achieved by using metallic glands for shielded cable entry into metal
Electronics Enclosures. Expose enough of the braid/foil/drain where it passes
through the gland so that the shield materials can be wrapped backwards onto
the cable jacket and captured inside the gland, and tightened up against the
metal interior.
Inductive loads connected to the low voltage “Alarm Contacts” are not
recommended. However, if this becomes a necessity, follow proper techniques
and wiring practices. Install an appropriate transient voltage suppression
device (low voltage MOV, “Transzorb,” or R/C) as close as possible to the
inductive device to reduce the generation of transients. Do not run this type
of signal wiring along with other I/O or DC in the sameshielded cable.
Inductive load wiring must be separated from other circuits in conduit by
using an additional cable shield on the offending cable.

PN 903-8663, Rev H
In general, for optimum protection against high frequency transients and other disturbances, do not allow installation of this Analyzer where its unshielded I/O and DC circuits are physically mixed with AC mains or any other circuit that could induce transients into the Analyzer or the overall system. Examples of electrical events and devices known for the generation of harmful electromagnetic disturbances include motors, capacitor bank switching, storm related transients, RF welding equipment, static, and walkie-talkies.

Overview
This manual describes how to retrofit a Heated Acid Gas (HAG) Sample Probe
when replacing an existing Sample Valve, and how to install the HAG Probe for
new applications (Chapter 2). This manual also describes (in Chapter 3) how to
diagnose problems with the HAG Sample Probe and how to change out replaceable
parts to ensure the HAG Sample Probe continues to operate at peak efficiency.
PN 903-8663, Rev H
Overview | 1-1
About the Heated Acid Gas Sample Probe
The Sample Probe is a heated probe that uses a dedicated temperature
controller to heat and maintain the temperature of the sample gas above the
sample dewpoint temperature. To do this, the analyzer uses a control loop with
a temperature sensor to control the temperature of the Sample Probe.
The set points, Too Hot and Too Cold, depend on the application. The set point
is usually set at 10 °C above the sample dewpoint temperature, to a maximum of
120 °C. The Too Cold set point is typically a few degrees below this and the
Too Hot is typically a few degrees above.
The Probe Heater is protected from overheating by a temperature switch, which
will disconnect power if the Heater Assembly exceeds approximately 170 °C/338
°F. If the temperature of the probe falls below the analyzer Too Cold
parameter, the analyzer Microcontroller board will de-energize the flow
control valve to allow zero gas to backpurge the entire sample system.
The aspirator draws sample gas from the process duct and through the analyzer
sample system, and then returns it to the process duct (see Figure 1-1 for an
example plumbing schematic). Valves contained within the probe allow for
complete isolation of the sample system from the process duct.
Figure 1-1 is an example drawing only. For your system, refer to Final “As-
Built” drawings in the Documentation Package folder shipped with the
analyzer/probe.

About the Analyzer Sample System
The components of the Heated Acid Gas Sample Probe and their functions are
detailed below (see Figures 1-2, 1-3, 1-4.1, and 1-4.2).
Component
Function
HAG Sample Probe Sample Probe
The HAG Probe is made up of the following components: Extends into process duct to obtain a representative sample.
Sample Isolation Valve (Red handle)
Isolates the analyzer’s sample path from the Sample Probe that extends into the process duct.
Fiber Filter
Part of the Fiber Filter Assembly, which is the first filtration stage, this filter removes coarse particulate and some liquids.
Membrane Filter
The Sintered Disk, the third filtration stage, removes small quantities of low surface tension liquids (such as hydrocarbons) that are not extracted by the first and second filtration stages.
Aspirator
Provides flow to move the sample gas through the sample path, and the condensed sulfur (in the Sample Probe) back to the process duct.
Flow Restrictor
(in Solenoid Block) Provides a consistent back-pressure for setting the Aspirator Air, which reduces sample rate fluctuations caused by process pressure fluctuations. The flow rate obtained at a gauge pressure of 210 KPA (30 PSIG) is 30 L/min (1 SCFM).
CAUTION: To avoid plugging problems within the HAG Probe, do not remove this fitting or replace it with a general purpose fitting.
Vent Isolation Valve (Black handle)
Isolates the analyzer’s sample path from the process duct.
Double Block Valve Assembly (Optional)
This optional two-valve assembly (Sample and Vent) isolates the process gas
from the upper portion of the HAG Probe, to allow for service on the upper
portion and main Isolation Valves of the HAG Probe without having to remove
the probe from the process. (Special applications only.)
Sample Isolation Needle Valve This needle valve (T-handle, below and closest
to Red Sample Valve handle) can be closed to isolate the HAG Probe from the
sample stream and to allow service to be performed on the upper sections of
the HAG Probe.
Vent Isolation Needle Valve This needle valve (T-handle, below and closest to
Black Vent Valve handle) can be closed to isolate the HAG Probe from the
sample stream and the upper sections of the HAG Probe. Close this valve to
allow service to be performed on the upper sections of the Probe.
Pipe Adapter
Threaded connection provides mounting of the Sample Probe to the process duct.
Probe Heater Assembly The Probe Heater maintains the temperature of the Sample Probe above the dewpoint temperature to prevent condensation of liquids.
Connection Tube
(Thermal Insulation Tube) This stainless steel tube encases the Heater Cartridge wires, ground wires, and RTD cable, and joins the Junction (terminal) Box to the Heater Assembly (heater block).
Junction Box
Contains the termination block for power, ground, and RTD wiring for the Heater Assembly.

Installation and Start-Up
Safety Considerations
Before installing the HAG Probe and powering up its Heater, review and follow
all safety information in this chapter and under “Personnel and Equipment
Safety Information” following the Table of Contents. This information
describes procedures to follow to avoid personal injury and/or damage to the
equipment. All regulatory agency and personnel safety procedures for your
jurisdiction must be followed.
Take all appropriate safety precautions to prepare for replacing the existing
Sample Valve with a HAG Probe.
This includes obtaining a “hot permit” plus meeting all other safety
requirements, as required by company and hazardous areas safety policies.
Under normal operating conditions, lethal concentrations of H2S and other
toxic gases from the process duct may be present within the sample system. The
sample system is defined as all components in the analyzer system through
which sample gas passes.
A breathing apparatus must be worn when installing/removing equipment from the
sample gas extraction point. The sample stream is under positive pressure, and
injury or death from inhaling toxic gases in the sample stream could result
from attempting to install/remove equipment without the use of a breathing
apparatus.

Installation and Start-Up | 2-1
Pre-Installation Requirements
Storage Prior to Installation
If the HAG Probe is stored for any period of time prior to installation, store the equipment in an environment where it is not subject to dripping or splashing liquids, corrosive gases, high humidity, or excessive heat or cold. Recommended storage conditions include:
Temperature: Relative Humidity:
0 °C to 50 °C (32 °F to 122 °F) <70 %
Failure to comply with these storage conditions will void your warranty.
Uncrating and Inspecting the HAG Sample Probe
When lifting the HAG Sample Probe out of its shipping container, or when transporting it to the process pipe, do not use its isolation valve handles.
The Probe Heater Assembly is shipped detached from the Sample Probe Assembly.
This allows for easier installation of the equipment. Upon receiving the
Sample Probe and the Probe Heater assemblies, remove them from their shipping
crates and examine their exteriors for any obvious damage.
If equipment is damaged or parts are missing, notify the carrier and contact
AMETEK Service (www.ametekpi.com/customersupport/aftermarket) immediately. If
damage is found, contact AMETEK Service to verify if damaged parts will
require replacement prior to safely installing and operating the equipment.

Installing the Heated Acid Gas Sample Probe
This section describes how to retrofit an existing Sample Valve with AMETEK’s
HAG Sample Probe, and how to install a HAG Sample Probe in new applications.
Refer to the appropriate section for your installation requirement.
The Sample Probe must be installed a minimum of two pipe diameters away from
any process piping component that causes process turbulence, such as bends,
valves, etc. Failure to comply with this recommendation may result in an
excessively noisy and therefore, erroneous, output signal.
To avoid plugging, do not install the Sample Probe horizontally.
IMPORTANT Performing HAG Probe start-up and verification procedures requires
working from analyzer’s System 200 Configurator Software. Familiarize yourself
with the Software operations before installing the HAG Probe. See “Navigating
in the Software” in the analyzer User Manual for more information.
2-4 | Heated Acid Gas Sample Probe
PN 903-8663, Rev H
Installing the HAG Sample Probe in New Applications
For installation drawings, refer to the Final “As-Built” drawings in the
Documentation Package folder shipped with the analyzer or the HAG Sample
Probe.
To install the HAG Probe:
1. Prepare the HAG Probe for installation:
· Ensure the probe end is the proper length for the process duct being sampled
from. If necessary, cut the probe end so that it extends 3050 % into the
process duct.
· Ensure the Sample (Red) and Vent (Black) isolation handles on the HAG Probe
are closed.
Potentially lethal concentrations of H2S and/or other toxic gases are present
in the process. Before proceeding, follow all necessary safety precautions,
such as wearing a supply air apparatus.
2. Install the new HAG Probe:
Applications with a Threaded connection: Apply a thin bead of pipe sealant on
the lower threads of the Sample Probe Pipe Adapter. Use care to avoid cross-
threading the threads on the Sample Probe.
Applications with a Flange: Remove the existing flange blind and, using a
gasket suitable for the application, connect the Sample Probe (comes with
replacement flange assembly) to the flange on the process duct.
If mounting the HAG Probe on a vertical section of pipe, it is critical to
position the probe with the Vent Valve (Black handle) angled downward
slightly.
3. Lay out the Sample and Vent Lines between the probe and the analyzer.
PN 903-8663, Rev H
Installation and Start-Up | 2-5
4. Connect the Sample and Vent Lines to the HAG Probe.
The Sample Line fitting is on the same side of the HAG Probe as the Sample
isolation valve (Red handle). The Vent Line fitting is on the same side of the
HAG Probe as the Vent isolation valve (Black handle).
Do not install the Insulating Flex Pack on the HAG Probe at this time. This
will be done after the analyzer and HAG Probe have been powered up and the
Sample Probe fittings have been leak-checked (with no leaks).
5. Connect the Sample and Vent Lines to the Sample Inlet/Outlet Fittings on
the analyzer:
Non-Shelter Installations: Route the Sample Line to the analyzer and connect
it to the Sample Inlet fitting.
Route the Vent Line to the analyzer and connect it to the Vent Outlet fitting.
Shelter Installations: Route the Sample Line through the hole marked “Sample
Line” on the side of the shelter and connect it to the Sample Inlet fitting.

Retrofitting the HAG Sample Probe
This section describes replacing an existing Sample Valve with a HAG Sample
Probe. Refer to the drawings shipped with the Sample Probe.
To replace an existing Sample Valve with the HAG Sample Probe:
1. Prepare the probe end of the Sample Probe for installation by ensuring the
probe is the proper length for the process duct being sampled from. If
necessary, cut the probe end so that it extends 3050 % into the process duct.
Apply Teflon tape or a liquid thread sealant (must comply with company/
hazardous location policy) to the probe pipe threads and thread it into the
bottom of the Pipe Adapter.
2. While working from the System 200 Configurator Software, view and record
the analyzer’s current Flow Control Mode.
3. Manually Zero the sample system for 23 minutes to remove all residual gas
in the sample system. Information on how to do this is described in the
analyzer User Manual.
4. After the Zero is complete, isolate the analyzer sample system from the
process duct by closing the isolation valve on the existing Sample valve.
5. Power down the analyzer and its temperature zone circuitry. Refer to the
analyzer User Manual for safe power down instructions.
Hazardous Locations Before proceeding, test the area around the analyzer for
flammable gases and proceed only when the area is safe.
Do not remove the cover of the Explosion-Proof Digital Communications Port on
the front of the Lower Enclosure (931 or 932 Analyzers) and do not power
up/down the analyzer or computer if there is an explosive gas atmosphere
present.
6. Remove the Sample Line from the existing Sample Valve.
Potentially lethal concentrations of H2S and/or other toxic gases are present
in the process. Before proceeding, follow all necessary safety precautions,
such as wearing a supply air apparatus.

Powering Up the Probe Heater Assembly and Analyzer
This section describes how to safely power up the analyzer, the Probe Heater
Assembly, and the rest of the temperature zone circuitry for operation after
installation or maintenance.
If the entire analyzer system (analyzer and HAG Probe) has been installed or
reassembled, continue with this procedure; if not, complete the
installation/electrical connections before continuing.
Hazardous Locations Before proceeding, test the area around the analyzer for
flammable gases and proceed only when the area is safe.
Do not remove the cover of the Explosion-Proof Digital Communications Port on
the front of the Lower Enclosure (931 or 932 Analyzers) and do not power
up/down the analyzer or computer if there is an explosive gas atmosphere
present.
Refer to the analyzer User Manual for additional safety and important
information about the operation of the analyzer before and during power-up.
After the entire analyzer system has been installed (or maintenance has been
completed) and the analyzer is ready to be put into service, power up the
analyzer and its temperature zone circuitry:
1. Before powering up the analyzer: Systems without the optional Double Block
Valve: Ensure the Vent Line valve (Black handle) and the Sample Line valve
(Red handle) are closed, to isolate the process gas from the sample system.
Systems with the optional Double Block Valve: Ensure the upper Vent Line
(Black handle) and Sample Line (Red handle) valves and lower Vent Line and
Sample Line (T-handle) valves are closed, to isolate the HAG Probe from the

disconnect switch, if used) that supplies AC power to the analyzer.
Retrofits (i.e., AMETEK 732 Analyzers): Turn the power switch on the rear
panel to On.
3. Install the Insulating Flex Pack on the Sample Probe to allow the Sample
Probe to warm up quickly.
4. Verify the Probe Heater Assembly is working.
Applications where the Probe Heater Assembly is controlled by the analyzer:
This is part of the overall analyzer verification, as described under the
section “Analyzer Start-Up and Verification” in the analyzer User Manual.
Upon power-up the “f: Probe temperature too low” alarm error message typically
will be displayed due to a low Probe Heater Assembly temperature. For more
information about this and other Probe Heater Assemblyrelated alarms, refer to
“Analyzer Start-Up Diagnostics Checklist” and “Host Controller Board Error
Conditions and Corrective Action” in the analyzer User Manual.
If it is suspected there is a shorted RTD, ensure AC power is making it to the
Probe Heater. To do this, check the wiring by measuring across Terminals 4 and
5 in the Heater Assembly Junction Box.
Retrofit applications where the Probe Heater Assembly is controlled by a
standalone external Temperature Controller: Check the Temperature Controller
display to verify the temperature is increasing and stabilizes at the required
temperature for the application.
5. Complete all other checks for starting up the analyzer, as described under
the section “Analyzer Start-Up and Verification” in the analyzer User Manual.
PN 903-8663, Rev H
Installation and Start-Up | 2-23
6. After all temperature zones have reached normal operating temperatures
(for 931 or 932 Analyzers, the normal operating temperatures are above the Too
Cold set point; for retrofits with a standalone Temperature Controller, the
temperature has stabilized at the required temperature), open the valves as
listed below:
Systems without the optional Double Block Valve: Slowly open the Vent Line
valve (Black handle) and then the Sample Line valve (Red handle) on the HAG
Probe to allow sample gas into the sample system.
Systems with the optional Double Block Valve: Slowly open the lower Vent Line
valve (T-handle) and then open the upper Vent Line valve (Black handle). Then,
slowly open the lower Sample Line (T-handle) valve and then open the upper
Sample Line valve (Red handle) to allow sample gas into the sample system.
After the valves have been opened, turn on the Aspirator Gas and adjust the
sample gas flow rate to the recommended pressure listed on the system drawings
shipped with the analyzer or HAG Probe.

Diagnostic Flowcharts
This section describes how to check different HAG Probe areas for possible
problems, to reduce the occurrence of problems with the HAG Probe. Since most
analyzer problems originate within the sample system, the primary objective of
the Flow Charts is proper care of the sample system.
Preventing leaks in the HAG Probe and the rest of the sample system is
critical to proper analyzer operation. Leak check the HAG Probe and the rest
of the sample system whenever it has been dismantled for maintenance.
Setup (tab)
Temp Control
Maintenance details and assembly drawings are included in this chapter. Refer
to the analyzer User Manual for additional information while performing
maintenance.
Checking and Recording Operating and Set Point Temperatures
Approximately every six (6) months, check and record the HAG Probe operating
Temperature and Setpoint temperatures (Temperature Control dialog box: Setup
tabTemp Control). Ensure the operating Temperature is within proper range of
the Setpoint temperature. Refer to the analyzer User Manual for descriptions
of these settings.
Depending on process stream conditions, the suggested maintenance frequency may be shortened or extended.
If temperatures vary outside this range, inspect the Insulating Flex Pack on
the HAG Sample Probe. If there is any exposed metal, take appropriate safety
precautions and re-insulate it properly.

Maintenance and Troubleshooting | 3-5
See “HAG Sample Probe
Extended Maintenance Spare Parts” for Isolation valve ordering numbers for
your application.
Possible Leaks in Sample Probe Valves
The Sample/Vent Isolation (or optional Double Block) valves typically do not
require regular maintenance. However, if it appears that leaks are originating
from the HAG Probe Main Sample/Vent Isolation Ball Valves or from the optional
Double Block Valves the valves assembly will have to be immediately replaced
or rebuilt.
IMPORTANT Depending on the application for your analyzer, the Sample Probe may be either Basic or Extended Temperature.
To avoid further delays during maintenance, be sure to have on-site all required parts that are being replaced prior to disassembling the Sample Probe valve assembly. Twenty-four (24) hours of curing time is required for the liquid sealant.
Probe-Related Alarms are Active
The Heater Assembly temperature zone circuitry does not require regular
maintenance. However, if problems arise with the Heater (Probe-related alarms
are active), determine the origin of the problem and immediately replace the
faulty part(s). These parts can include the Over-Temperature Switch, Heater
Cartridge, and RTD.
Refer to the “Maintenance and Troubleshooting” chapter (see section “Host
Controller Board Error Conditions and Corrective Action”) in the analyzer User
Manual for information on specific alarms. See “Replacing Probe Heater Parts
Extended Maintenance” in this chapter.
IMPORTANT Be sure to have on-site the proper replacement parts prior to
disassembling the Heater Assembly. Refer to the “HAG Sample Probe Heater
Assembly Spare Parts” list in this chapter for part numbers.
Checking Flamepaths and Gaps
During each Probe Heater Assembly maintenance, use a feeler gauge to check the
flamepath gap between the Heater Body and the Heater Cover (see Figure 3-4 for
location). The gap must not exceed 0.04 mm; if the gap exceeds this value,
contact AMETEK for advice. See “Examining and Caring For the Flamepaths” in
this chapter for more information.

section describes how to power down the analyzer for all maintenance
requirements discussed in this chapter. This section refers to 931 or 932
Analyzers only. For 919 or 920 Analyzers, refer to the companion document
“919/920 Analyzers with Heated Acid Gas Sample Probe” Manual Supplement
shipped with the HAG Probe or analyzer.
Hazardous Locations Before proceeding, test the area around the analyzer for
flammable gases and proceed only when the area is safe.
Do not remove the cover of the Explosion-Proof Digital Communications Port on
the front of the Lower Enclosure (931 or 932 Analyzers) and do not power
up/down the analyzer or computer if there is an explosive gas atmosphere
present.
Follow appropriate regulatory and/or company procedures to lock out the analyzer while the HAG Probe or its Heater Assembly is being worked on.

10. Replace the Sample Probe on the process duct.
All regulatory agency, personnel safety procedures, and installation/ removal
procedures must be followed during the installation/removal of the components
that make up the sample system. A breathing apparatus must be worn when
installing/removing the Sample Probe. The process duct may be under positive
pressure, and injury or death from inhaling toxic gases in the process could
result from attempting to install/remove the equipment without the use of a
breathing apparatus.
If applicable, remove the flange blind (or remove the cap) and connect the
Sample Probe to the process duct.
11. Using a suitable detergent-based leak detection fluid (e.g., Snoop®),
leakcheck the threaded connections.
Do not use a leak detection fluid on hot fittings. If the analyzer/probe
system is at operating temperature, the temperature zone circuitry must be
powered down to allow the temperature zones to cool down before using a leak
detection fluid on the fittings.
For detailed information about leak-checking fittings, refer to “Sample System
Leak Check” in the analyzer User Manual.
Applications With a Threaded Connection: Leak-check the Pipe Adapter threads
(where the Pipe Adapter enters the threaded connection on the process), the
Isolation Needle Valves T-handles (if the probe is a Double Block HAG Probe,
and if these valves were replaced), and the Sample/Vent Line connection points
on the Sample Probe.
Applications With a Flange: Leak-check the Pipe Adapter threads/replacement
flange assembly, the Isolation Needle Valves T-handles (if the probe is a
Double Block HAG Probe, and if these valves were replaced), and the
Sample/Vent Line connection points on the Sample Probe.
3-18 | Heated Acid Gas Sample Probe
PN 903-8663, Rev H
12. After the leak-check passes, and maintenance on the Heater Assembly is
complete, replace the Heater Assembly (Figure 3-3):
a. Use a non-abrasive cloth to gently clean the joining surfaces (heat
transfer) of the Heater Block and the Sample Probe.
b. Place the Heater Assembly on the Sample Probe.

10. Replace the RTD:
a. Disconnect the RTD wiring and remove the RTD from the Heater Block.
b. Remove the Heater Plug.
c. Install the new RTD (Part No. 300-4924) in the Heater Block.
Connect the new RTD wires to the old RED wires and pull the wires through the
Thermal Insulation Tube from the Junction Box side.
Carefully pull the RTD cable back from the Junction Box end until there is no
excess cable remaining inside the Heater Block.
d. Replace the Heater Plug.
e. Continue with Step 11 for final Junction Box assembly.
11. To allow for easier wiring inside the Junction Box, cut any excess wire
leads to approximately 4″ (10 cm).
Wire the terminal strip as per your notes (or Figure 3-4).
12. Using a soft, non-abrasive cloth, clean the o-ring groove and the joining
surfaces (flamepath) on the Heater Block and its cover. Take care to avoid
dropping any contaminants into the Heater Block.
13. Insert the new Heater Assembly o-ring (Part No. 300-8721) by using your
thumbs to push it into the o-ring groove in the Heater Block. Ensure it is
properly seated in the groove.

14. Ensure the joining surfaces (flamepath) of the Heater Assembly Cover and
the Heater Block are free of debris. Replace the Cover on the Heater Block and
the eight (8) M6 x 16 screws that secure the Cover to the Heater Block.
AMETEK recommends applying a small amount of high-temperature thread lubricant
to the threads. Tighten the screws.
The thread lubricant must not contain copper.
15. Reposition the conduit (North American installations) or cable(s)
(European installations) to the Probe Heater Assembly, reconnect the field
wires, and reassemble the Junction Box (Figure 3-3 and Figure 3-4):
a. Insert the field wires into the Terminal Block tag locations, according to
your notes or Figure 3-4.
Tighten the screws to secure each wire to the appropriate Terminal Block tag
location in the Junction Box.
b. With the Junction Box o-ring in place on the Junction Box Cover, thread the
Cover onto the Junction Box Body by hand and then tighten it using a suitable
tool. Take care to avoid damaging the o-ring and the threads.
Tighten the set screw on the end of the Junction Box Cover.
Reconnect the ground to the Junction Box Body using the ground screw and
washer.
c. Tighten the conduit connectors (North American installations) or cable
gland(s) (European installations).
16. If all maintenance on the Heater Assembly is complete, replace and secure
the Heater Assembly on the Sample Probe, as described in the section
“Replacing Sample Probe Parts.”
The procedure is complete.

Maintenance and Troubleshooting | 3-31
Examining and Caring For the Flamepaths
The HAG Sample Probe Heater Assembly is designed with a flamepath that will
prevent flame propagation from within the Heater Assembly to the outside,
should an internal explosion occur. The minimum flamepath length must be at
least 9.5 mm with a maximum surface roughness of 6.3 µm. The gap between the
flange surfaces with the bolts tightened must not exceed 0.04 mm. Use A2
stainless steel fasteners with yield stress 450 MPa (65,300 psi).
The flamepaths on the Heater Assembly consist of:
· The Heater Assembly joining surfaces (Heater Body and the Heater Cover).
During each analyzer maintenance, use a feeler gauge to check the flamepath
gap between Heater (Block) Body and the Heater Cover joining surfaces. The gap
must not exceed 0.04 mm; if the gap exceeds this value, contact AMETEK for
advice. See Warning below.
· All separable joints between the Heater Body and its Junction Box. These
parts include the threads in the Heater Body and the Junction Box used to
connect to the Thermal Insulation Tube, the threads on each end of the Thermal
Insulation Tube, the larger diameter threads on the Junction Box and its
Cover, and the o-ring groove. See Caution and Warning below.
If the Thermal Insulation Tube is removed, take extreme care to avoid damaging
its threads and those in the Heater Block. Also, take care to avoid damaging
the threads on the Junction Box and its cover. After removing these parts,
cover the threaded end to avoid damaging the threads. Clean, defect-free
threads are essential to ensure a flameproof connection.
When performing equipment maintenance in hazardous areas, all safety standards and procedures must be followed, as specified by the Owner Company, local electrical-inspection authority, and National/ EU regulations.
Do not apply power to the analyzer/HAG Sample Probe if there is damage
(scratches, indentations, or wear) to any flamepath. Applying power to an
analyzer with a damaged flamepath is dangerous and could result in serious
injury or death and/or serious damage to equipment. Review this section for
complete information about caring for the flamepaths.
Replace the parts immediately if damage or wear is apparent. Contact AMETEK
immediately if there is any doubt about the integrity of any flamepath.

PN 903-8663, Rev H
Specifications
The Heated Acid Gas (HAG) Probe is designed for applications in which process gas is to be returned to the process pipe, where the process gas contains only small quantities of particulate and entrained liquids.
Methodology
The heated sample probe simultaneously extracts a sample, maintains high
integrity, prevents condensation, and provides a sample return point to create
a truly closed-loop sampling process.
