Exhausting is performed by the pressure regulator.
When using the product

3-way on/off valves before port P1 and after port P2 (
è
Fig. 3, Fig. 4):
1. Close the 3-way on/off valve at port P1 (inlet).
2. Close the 3-way on/off valve at port P2 (outlet).
The pressure booster is exhausted by port 3 on the two 3-way on/off valves.

Exhausting the air reservoir faster
Close the on/off valve between the DPA pressure booster and the CRVZS air reservoir (

This contains the air in the high-pressure chamber of the pressure booster. The rotary knob remains in
the set position.
