NOTICE
Compressor Motor Damage!
Disconnect all electric power including remote
disconnects prior to evacuating refrigerant.
System power shall not be applied to the chiller
while the refrigerant system is in a vacuum.
Failure to disconnect power prior to evacuating
th
e refrigerant system, or application of
power
while the refrigerant system is in a vacuum, will
cause compressor motor damage due to the
nature of the solid state starter.
Important: Do NOT energize the unit if the refrigerant
side of the system is in a vacuum.
The Benshaw Solid State Starter is an “in-the-delta”
starter. The starter
leads and motor leads are always
energized. Catastrophic damage to the compressor motor
will occur if supply power is applied while the system is in
a vacuum.
Identify Existing Solid State
Starter
Trane has used three styles of solid state starters over the
past several years. Determine whether the SSS is an A515,
EasySTART or Intelligent Technology (IT) by comparing
the unit to the photographs below.
