Section 1-4: Important Safety Notes
• The LMV3 is a safety device. Under no circumstances should the unit be modified or
opened. SCC Inc. will not assume responsibility for damage resulting from unauthorized
modification of the unit.
• After commissioning, and after each service visit, the flue gas values should be checked
across the firing range.
• All activities (mounting, installation, service work, etc.) must be performed by qualified
staff.
• Before performing any work in the connection area of the LMV3, disconnect the unit
from the main supply (all-polar disconnection).
• Protection against electrical shock hazard on the LMV3 and all other connected
electrical components must be ensured through good wiring and grounding practices.
• Fall or shock can adversely affect the safety functions of an LMV3. Such units must not
be put into operation, even if they do not exhibit any apparent damage.
• The coupling that is used between the actuator and the driven valve / damper is safety
related, and must be of a robust and flexible design. Should this coupling fail during
operation, the LMV3 will no longer have control of the burner’s combustion, bringing
about a hazardous condition.
• Condensation and the entry of water into the unit must be avoided.
