Coolers from serial nos.: 95.. also have a mains selector (S1) on the basic board for either 230V 50Hz
or 115V 60Hz operation on the basic circuit board (see circuit diagram in appendix).
Before commissioning, use a screwdriver to turn the selector to the correct position 230/115
depending on your main power input supply.
