Refrigerant Recovery Unit

2020-9000 Rev 0
ATTENTION:
Use an in-line filter when recovering liquid. Contaminants
(particularly from the bottom of recovery cylinders) can enter the ECO-
2020 and become lodged in the valve seats causing damage and
resulting in leaks. We recommend using Bacharach in-line filter
P/N 2020-0001 for optimum recovery speed.
IMPORTANT:
Make all hose connections as shown in Figure 7.
Ensure that all connections are correct and secure.
IMPORTANT:
Ensure all valves are CLOSED and ensure the filter
screen is clean.
