Frequently Asked Questions

The return number helps us to track the progress of your repair. Instruments sent without the proper return paperwork, return number and information on the outside of the package will cause delays in processing your order.

Pre-approved orders reduce the time it takes to return your instrument. We strongly recommend that you include the pre-approved amount on your request form. Pre-approval is required for the 24 Hour Priority Service.

In all cases, the actual cost of your repair will be applied to your purchase order or credit card. The pre-approved amount is an estimate maximum cost based on our experience of servicing instruments. A combustion analyzer, for example, may only need calibrated or one sensor and calibration which is less than the “Not to Exceed” price.

We will contact you for approval in the event the actual cost will exceed the pre-approved amount. This typically indicates the service is more than just a sensor and / or calibration. Several sensors, a pump, circuit boards, etc.. may need replaced.

Contact our customer service department at (800) 736-4666 extension 2. Our Customer Service Reps can suggest a replacement for your instrument if we are not able to repair it.

No. For security reasons, we do not accept credit card information through our website. We will contact you for your credit card information when your instrument is ready to be returned to you. Once approved, the paper copy in our possession will be shredded / destroyed. We do not keep any credit card information.

You will receive a confirmation email within a few minutes of submitting your request. If you do not receive a confirmation within 1-2 hours, please call our customer service department at (800) 736-4666 extension 2.

Generally, instruments are calibrated on a yearly basis. A few instruments may require calibration every 6 to 9 months. Your company procedures may require more frequent calibrations and should be followed.

Standard calibration includes a certificate that provides the date of calibration, due date for next calibration, part number, serial number, model, return number and the technician number who performed the service.

The NIST (National Institute of Standards & Technology) is a government agency that sets the standards for measurement and calibration. A NIST certificate provides traceability back to this government agency, and includes “before” and “after” readings, which are also known as “as found” and “as left” readings. There is an extra $105.00 charge added to the standard calibration for this certificate. A NIST certificate is generally required by most hospitals, laboratories and government agencies. You need this certificate if traceability is required.

Calibration is the process used to adjust an instrument’s readout when a known gas source is applied. The instrument’s sensor drifts over a period of time and needs to be adjusted periodically to assure the readout is accurate. Instruments without a digital readout or physical scale cannot be calibrated. A functional test is the process used to determine if an instrument is working as it was intended. Functional tests are performed on instruments that do not have digital readout or scales. Instruments that are tested functionally include Leakators, Informants and H10’s.

We strive to repair all instruments within 4 business days upon receipt with our standard repair service. A 24 Hour Priority Service is available for select instruments if you need your instrument back sooner.

All accessories including probes, filters, printers, carrying case, etc. should be included with your instrument. This will ensure your instruments and all its components are in working order when returned to you.

Disposable batteries do not have to be included with your instrument. Rechargeable batteries should be included except for the large lithium ion batteries on the PGM-IR. Part numbers for these instruments include the 3015-4484, 3015-4790, 3015-5696, 3015-5720 and 3015-5751. Return your PGM-IR without the rechargeable battery. If you are unsure, please contact our customer service department at (800) 736-4666 extension 2.

RMA stands for Return Material Authorization and RGA stands for Return Goods Authorization.

No. Our portable instruments are only sold through our authorized distributor partners. We only service our products to end users and distributors alike.

Bacharach may offer a trade in rebate direct to end users. Please contact customer service at (800) 736-4666 extension 2 for more information.

Why does my analyzer show “O2 Sensor Missing” when the sensor is installed?
Either the sensor is installed incorrectly, or the sensor is expired and needs replaced.

Why is my CO2 reading stuck and will not change?
The CO2 reading is a calculated number based on the fuel selected in the analyzer setup and the O2 reading. Typically, the CO2 appears stuck when the O2 sensor needs replaced and the O2 reading is always at 0.0%.

If I replace my oxygen sensor, do I need to calibrate the analyzer?
No. Each time you power up the instrument, it goes through a 60 second warm-up countdown. At the end of that countdown, the analyzer sets the O2 reading at 20.9% (ambient air O2 content) and the CO at 0 ppm, effectively calibrating the O2 channel.

How do I reset my O2 sensor code date on my Fyrite InTech and Fyrite Insight Plus?
Enter into the main menu, then the diagnostics menu, and finally select the O2 Sensor Life option. Depress the F3 key to reset the date code. Enter the O2 date code from the new sensor and depress the center key. Verify the month and year are correct, then depress the center key again. Return to the main menu and begin testing. See section 5.4.3 of the user manual for further specification.

What is the suggested calibration interval of my combustion analyzer?
Depending on which model you have, it can be either 6 months or 1 year. PCA, PCA2, Fyrite Tech60, Fyrite Pro and ECA450 have a 6 month calibration interval. Fyrite InTech, Fyrite Insight, Fyrite Insight Plus, PCA3 and PCA 400 have a 1 year calibration interval.

How do the B-Smart sensors work?
The B-Smart CO sensors are standard CO sensors that are run through multiple gas level tests and are given a B-Smart code based on the sensor output. Once installed in an analyzer, this B-Smart code is entered into the analyzer, which tells the instrument how to interpret the sensor output, and what to display on the analyzer screen. See section 5.4.5 of the user manual for further specification.

Why is my T-Stack reading showing as stars (******)?
This is an indication that the thermocouple is not connected to the correct input, is bad, or the wires inside the thermocouple male connector on the probe assembly are broken or disconnected. See section 6.1 of the user manual for further specification.

Why am I getting dashes (—-) for my efficiency, CO2, excess air and CO air free readings?
These are all calculated values that require all inputs be present and that the O2 reading is less than 16%. If the O2 reading is 16% or higher, the programming of the analyzer will only show dashes, thus indicating an extremely poor combustion process, or no valid combustion process is occurring. This can also occur if there is a leak or obstruction in the probe assembly or an inoperable sample pump. See section 6.1 of the user manual for further specification.

Why do I not get any change in my readings when I place the probe in my furnace exhaust stack?
Make sure the analyzer is in the RUN mode and the pump is running. Check that the T-Stack is indicating a temperature and that the O2 level is below 16%. If the O2 level is 16% or higher, check the device you are testing to make sure it is actually exhausting gasses lower than 16%. Check the probe for leaks or obstructions, and check the pump for proper vacuum or pull.

How Do I Resolve an “1800 Fault”?
Please see our technical bulletin HGM-MZ Sample Pump Flow and Manifold Testing for information on resolving an 1800 fault. It is the first topic covered in the bulletin. See section 4.5.3 of the user manual for further specification.

What is the supply voltage requirement?
100 to 240 VAC. See section 1.6 of the user manual for further specification.

Can the MZ be set for different refrigerants?
Each zone of the HGM-MZ can be set for a different refrigerant in the 1st Zone Setup screen. See section 4.2 of the user manual for further specification.

Can I set different alarm levels for different zones?
Each zone of the HGM-MZ can be set for different alarm levels in the 2nd Zone Setup screen. See section 4.3 of the user manual for further specification.

How do I reset alarms?
You must first acknowledge all alarms, then the alarms will reset automatically once the affected zones are sampled again.

How do I acknowledge alarms?
If the HGM-MZ is set for AUTO Acknowledge, the MZ will acknowledge automatically. If the HGM-MZ is set for MANUAL, it will be necessary to highlight each zone in the alarm screen and depress the left arrow to acknowledge each zone. See section 4.4.4 of the user manual for further specification.

How do I reset faults?
All faults will reset automatically once the fault condition is corrected.

Why do I need to set the sample tube length for each zone?
Setting the sample tube length is required so the HGM-MZ samples each zone for the correct amount of time to pull the sample into the HGM-MZ for proper analysis. See section 4.2.3 of the user manual for further specification.

What is the recommended maintenance required for the HGM-MZ?
Annually replace the hydrophobic filter inside the case and the external charcoal purge filter. Sample tube line end filters should be cleaned or replaced annually as well. See section 5.1 of the user manual for further specification.

Where should my purge line be routed?
Ideally, the purge line should be routed outside the building to an area that is free of all contaminates. If this is not possible, the purge line should be routed outside of any area where there might be refrigerant. The charcoal purge filter should be used in all instances. See section 2.2.3 of the user manual for further specification.

How can I stop moisture from entering my HGM-MZ?
You can use a line end water stop P/N 3015-5512 or an in-line water trap P/N 0007-1655 on each line that presents a moisture issue. See section 2.2.7 of the user manual for further specification.

How can I get a 4/20 ma analog output from the HGM-MZ?
You must purchase and install a 4/20 ma dual channel output PC card P/N 3015-5512. See section 2.9 of the user manual for further specification.

Can I connect the HGM-MZ to a BacNet communication interface?
Yes. This will require the purchase and installation of a BacNet converter P/N 3015-5705. See instruction BACnet Protocol Converter Kit for Use with Bacharach Multi-Zone Gas Monitors for further details.

How do I clean the pump on the H-10 PRO?
Remove the two Phillips head screws that are located inside the probe storage area.
CAUTION: DO NOT loosen or remove the two screws located on the back slotted area of the chassis.
Disconnect the battery and remove the chassis from the case, invert it, and lay it on the workspace.
Remove the four Torx screws from the bottom of the pump using a T6 Torx driver.
Disassemble the two plates and rubber valve plate from the pump.
Remove the rubber valve plate and clean with a clean, dry cotton swab and a can of keyboard duster.
CAUTION: When using the keyboard duster, make sure you hold the rubber valve plate to avoid blowing it from the bench top.
Re-assemble in reverse order and check pump for proper operation.

How do I determine the “Born-On” date for my Fyrite fluid?
The date code is printed on a sticker located on the label attached to your bottle of Fyrite fluid. It is the top number printed on the sticker.
