a suitable electrical supply. It is therefore important to check
whether the supply voltage stated on the unit's rating plate
is compatible with that of the mains electrical supply.
The rating plate also states the year of manufacture as well
as the type of refrigerant used with the required volume
capacity of each compressor circuit.
