On all components, the flow direction change is performed by rotating an instal-
lation by 180° around the vertical axis. The housing cover and pressure gauge
need to be replaced for the purpose.
Changing the pressure gauge and housing cover
(NL2, NL4, NL6)
g Fig. 9
Changing the housing cover is not possible on the NL1.
1. Remove the mounted pressure gauge by unscrewing it from the thread in an
anti-clockwise direction.
2. Remove the blanking plug and screw it in at the other side.
3. Remove the side cover caps on the compressed air connections by sliding a
suitable tool under the cover cap vanes, carefully lifting them up and taking
them off.
4. Lift the front and rear cover cap by pushing the lock-in bolts (2 on each side)
up on the latches.
Remove the cover caps carefully and evenly so that the 4 lock-in bolts
do not break off.
5. Now lift the front and rear cap evenly by carefully levering them open with a
suitable tool and taking them off.
6. Mount the cover caps on the opposite sides in the reverse order. The cover
cap with the AVENTICS logo should be facing to the front.
7. Screw the pressure gauge into the opposite side (see g 5.2. Mounting the
pressure gauge).
8. Screw the blanking plugs into the opposite side.
9.2.2 Turning the reservoir with bayonet catch
1. Release reservoir.
2. Rotate reservoir 180° and click it back into place.
The release is now pointing to the front.
9.2.3 Pressure regulator conversion with continuous pressure sup-
ply
No conversion is required for pressure regulators and precision pres-
sure regulators RGS-DS and RGP-DS with continuous pressure supply.
On these devices, air can be supplied from the left as well as the right.
