Macurco GD Operation Manual
Do not disassemble unit or attempt to repair or modify any component of this
instrument. This instrument contains no user serviceable parts, and substitution of
components may impair product performance.

6 Maintenance

The GD-6 is low maintenance. The unit uses a long life pellistor sensor that has a 5+ year life expectancy. The
detector's performance should be tested regularly by using gas as detailed in the Testing and Field Calibration
sections. All other maintenance and repair of products manufactured by Macurco are to be performed at the
appropriate Macurco manufacturing facility. Macurco does not sanction any third-party repair facilities.

6.1 Sensor Life Reset

1. Remove the Philips screw on the front of the GD-6. Pull the front cover of the unit off.
2. To reset the sensor life (rSt), from normal or warm-up mode, press the Next button five times to get to SEn
or Sensor Mode.
3. Then press the Enter button to get to "rSt" - Reset Sensor Mode.
4. Press the Enter button again to see the sensor reset status. If the sensor life has already been reset, done
"don" will be displayed. If it has not already been reset, "no" will be displayed. Push Next to change it to "
YES" (flashing) then push Enter to confirm the change (solid) and push Enter again to return to "rSt" in the
SEn menu. Push Next until "End" is displayed then push Enter to get back to normal operation. The sensor
life will be reset for 1 year.
NOTE : If the sensor is reset and the detector not replaced it is necessary to test and/or calibrate the sensor to
assure that it is still performing within acceptable specifications though the sensor is nearing the end of its expected
life. There will be no other indication of sensor performance.

6.2 Cleaning

Cleaning of the external surfaces is best carried out using a damp cloth with a mild detergent or soap. Use a vacuum
cleaner with soft brush to remove dust or contamination under the cover. Do not blow out the sensor with
compressed air.
CAUTION
Avoid the use of harsh cleaning materials, abrasives, and other organic solvents. Such materials may permanently
scratch the surfaces and damage the display window, labels, sensor, or instrument housing.
