7.1 Swapping Input Power Cord Connection (SRCOOL33K only)
The SRCOOL33K is furnished with two points of possible mains power input, one at the top of the unit and one at the bottom. Neither is
recommended over the other and a circuit inside the unit only allows one to be used at a time. If the unit is connected to mains power input
at both points, it will default to receiving power from the input at the bottom of the unit.
To switch the point of mains power input from bottom to top, use the following procedures. Reverse procedure to move point of input from
top to bottom.
WARNING! Make sure the unit is powered down and
disconnected from any mains power input when adjusting the
electrical connections. Personal injury and damage to the unit
will result if the unit is powered during these procedures.
