Operating manual for LT series cooling water heat exchanger

16.      Disposal

The cold circuit of the cooling water heat exchanger contains R407C cooling fluid
(R134a for tropical design). Before maintenance work on the cold circuit of the unit, it
should be drained and the cooling fluid disposed of adequately. Retrofitting on the cold
circuit of the installation may therefore only be performed by an expert company.
