Starters by Other Manufacturers (SBO)
Occasionally a customer chooses to reuse an existing starter or purchase a starter directly from a
starter manufacturer. While this can be accommodated, it requires careful coordination between
theTrane sales representative and the owner, engineer, and starter manufacturer because generic
or existing starters are not compatible with theTrane
Non-Trane starters must be modified with the proper components and control wiring before they
are connected to aTrane
representative; new starters should modified by the starter manufacturer.Trane assumes no
responsibility for the design, construction, compatibility, installation, startup, long-term support,
and will not maintain records or drawings for the resulting starter.
Trane provides a Starter by Others specification, which provides the information required for
others to build a starter that is compatible withTrane
When a non-Trane-provided starter is used, it must be modified to conform to the appropriateTrane
Starter by Others specification. SBO specifications are revised on a regular basis, so it is important
to obtain the correct version before building or modifying a starter by others.
It is also important to include the cost of conversion when determining the total cost of a non-Trane
starter; therefore, the owner should be provided with the appropriate SBO specification before the
decision is made to reuse or purchase a non-Trane starter. Components required for conversion
include but are not limited to:
