To maintain the guaranteed level of safety of the TCE, regular main-
tenance must be performed at max. 6 month intervals.
The maintenance operations must be performed in strict
compliance with the safety directions provided in this manual
and according to the applicable legislation and standards.
1. Check all TCE parts for wear with special attention to dirt, ero-
sion, rust, overheating.
2. Perform all tests and checks as envisaged in the section "Test-
ing".
!
5) Maintenance
This product is made up of different materials, some of which can be
recycled, such as plastic container, others must be disposed of as
waste, such as electronic board.
1. Disassemble TCE following in reverse order the procedures
described in chapter “Installation”.
2. As far as possible, separate all parts that can or must be recycled
or disposed of according to special procedures.
3. Sort the various materials and consign them to local licensed
firms for recovery and disposal.
Some electronic components may contain polluting sub-
stances; do not pollute the environment.
!
6) Disposal
TCE has two signalling LEDs which indicate the state of the relays.
Normally, they are “ON”. If they are off, this indicates a state of alarm,
meaning that the sensitive device has either triggered or malfunc-
tioned.
