NOTE: Non-contractual drawings. Refer to the certified
dimensional drawings.
For the positioning of the fixing points, weight distribution
and centre of gravity coordinates, also refer to the certified
drawings.
For 30RWA units without condenser, installed with a
remote air-cooled condenser, the refrigerant inlet and
outlet position correspond to the condenser water inlets
and outlets. See C in the legend on the left.
