Bacharach MVR-300 Maintenance Notification

MVR-300 VRF REFRIGERANT LEAK DETECTOR

MAINTENANCE NOTIFICATION

The MVR-300 VRF Refrigerant Leak Detector provides continuous monitoring of refrigerant leaks from variable refrigerant

ow (VRF) systems in occupied spaces. Bacharach recommends that equipment owners test or recalibrate the sensors in

deployed devices every 6 months to ensure optimal performance. The sensors have a 2-year operational life and should
be replaced every 2 years.

There are two methods for maintainig calibration in your facility’s leak detectors:

1. Perform a sensor calibration using a calibration adapter, regulator and calibration gas.

2. Replace the sensor with a pre-calibrated, plug-and-play sensor from the manufacturer.

OPTION 1: CALIBR ATION / BUMP TEST

To perform a sensor calibration or a bump test, the following accessories are required:

P/N DESCRIPTION

1100-2018 Calibration Adapter Kit (Includes extraction tool, magnetic

wand & tubing)

0051-2358 Pressure Regulator (0.5 L/Min)

0051-4208* Calibration Gas - R-410A (2,000 ppm)

0051-4209* Calibration Gas - R-407c (2,000 ppm)

0051-4210* Calibration Gas - R-404A (2,000 ppm)

0051-4211* Calibration Gas - R-404A (5,000 ppm)

0051-4206* Calibration Gas - R-32 (2,000 ppm)

*Use the calibration gas concentration listed on the label beneath the detector’s cover plate.

Please see the MVR-300 User Manual (P/N 6203-9000) for more information about performing calibration or a bump test.

OPTION 2: SENSOR REPLACEMENT

Pre-calibrated sensor modules are available for quick and easy, a plug-and-play sensor replacement.

Please see the MVR-300 User Manual (P/N 6203-9000) for more information about sensor replacement.

Bacharach recommends the use of a maintenance log to track the maintenance service performed on the MVR-300 refrigerant
monitors.
