25.1 Maintenance
Perform the following steps to maintain your unit.
•
Checking the Battery Level: Check the battery once a year. The output must be 2.7 volts (minimum).
Authorized personnel only must replace the battery if the output is below the minimum required
level or every five years.
•
Visually inspect your unit once a year. Make sure that there are no signs of corrosion or residue on
the PCBs. If these issues appear, it means that:
o
the TRIO is installed in an environment with high humidity, ammonia content, or some
other destructive agent.
There is a lack of (silicon) sealing or that the sealing has degraded.
•
Make sure that the silicon seal around the PGs installed in the knockouts is not cracked.
•
Check that the gasket is not
cracked.
