Safety Instruction

The KLC 10 is a safety component, and repair or adjustment must never be attempted. Replacement of
the flame detector is recommended in all cases of damage, due to impact shock, excessive moisture, or
other problems rendering it inoperable. Repair work must never be attempted and is strictly forbidden by
the relevant European Standards.

Prior to commissioning the unit; please carefully check that the wiring connections have been
made correctly. Also, before removing or checking the flame detector please ensure the power
supply is switched-off.
