AMC-SIR Refrigerant Gas Sensor/Transmitter

6 MAINTENANCE

6.1 GENERAL

The AMC-SIR Refrigerant Gas sensor/transmitter unit should be brushed or wiped as required,
depending on the rate of accumulation of any dust or dirt.
To avoid sensor damage, the unit MUST NOT be submerged in any liquids. Hosing or
splashing of the unit with any liquids must also be avoided.

6.2 VERIFICATION OF OPERATION

Scheduled calibration is critical in maintaining proper function of gas sensor/transmitters.
Verification of operation should be performed at least once every 6 months. For highly
demanding applications, more frequent verification is recommended.
As mentioned, Armstrong Monitoring offers a number of different maintenance plans to suit your
requirements see Section 5.

6.3 SENSOR/TRANSMITTER REPLACEMENT

When its signal is greatly reduced or unstable, a sensor/transmitter replacement is required; see
section 2.2 for replacement sensor/transmitter P/N. Contact AMC immediately.
Warning:
DO NOT replace the sensor/transmitter board while the system is still powered up.
