9.6 System discharge
1. evacuate the system
2. evacuate the exchanger, use all the cocks presents
3. use compressed air to blow the exchanger
4. dry completely the exchanger by an hot air jet; for greater safety ll the exchanger with glycoled solution
5. protect the exchanger from the air
6. remove the drain plugs to the pumps
Any anti-freeze liquid contained in the system should not be discharged freely as it is a pollutant.
It must be collected and reused.
Before starting a washing the plant.
