INSTALLATION MMR ICM 2000
REMOVING THE ICM
WARNING!
Do not disconnect the alarm coupling nut when pressure is shown on the harness gauge.
Always be sure that you have released all pressure from the regulator. Removing the
coupling nut with the regulator pressurized may result in serious personal injury or death.
Note:
All repair procedures assume that the alarm assembly is disconnected from the apparatus
cylinder.
1. Be sure the cylinder valve is completely closed.
2. Be sure that nothing blocks the regulator outlet. Open the bypass valve to relieve pressure in
the system.
