Maintenance and Service
Clean the detector and/or HUB before any maintenance or service.
WARNING!
Do not use silicone-type lubricants in assembling the detector and do not allow silicone vapors to be drawn
into the flow system while in operation. Silicone can desensitize the combustible gas sensor, thereby giving
erroneously low readings.
Use only genuine MSA replacement parts when performing any maintenance procedures on the detector.
Substitution of components can seriously impair performance.
Failure to follow the above can result in serious personal injury or loss of life.
WARNING!
Alterations of the HUB beyond the procedures described in the Setup, Deployment, Operation, and
Decomissioning sections of this manual or by anyone other than a person authorized by MSA, could cause
the unit to fail to perform properly.
Repair of the HUB must be performed by a person authorized by MSA.
Failure to follow this warning can result in serious personal injury or death.

Authorized Maintenance
Any authorized maintenance shall be performed in a non-hazardous area with HUB(s) and detector(s)
powered off. Clean the detector and/or HUB before any maintenance or service. Power off the HUB and the
detector before any further maintenance. Clean the detector and/or HUB before any further maintenance.
Observe proper grounding techniques to avoid damage caused by static discharge to the exposed
electronics. Orient the detector and/or HUB such that the printed circuit board is not accessible during
maintenance.
WARNING!
Before handling the PC board, ensure you are properly grounded; otherwise, static charges from your body
could damage the electronics. Such damage is not covered by the warranty.
Failure to follow this warning can result in serious personal injury or death.
MSA recommends always using the latest app.
