Observe safety regulations concerning the handling of solvent (see Point 2).
You must perform the maintenance on the economy filter when an adjustable number of cycles has run

The filter pressure is displayed on the filter pressure gauge (8)*. When the machine has run through the
specified number of cycles, a diagnostic message (see diagnosis list) indicates that it is time for filter
maintenance.

you perform maintenance on the economy filter. Do this by opening the ball valve (1) and closing ball
valves (2) and (3).
