Performing inspection / maintenance
Mounting the filter regulator
The filter regulator is re-assembled in reverse order.
First the components of the lower assembly are
replaced in the housing. The upper assembly is then
put back together.
If new seals are used during re-assembly,
thoroughly grease them prior to installation.
Mounting the bottom part
• Insert the O-ring Ø 31x2 [9] in the housing.
• Insert the valve piston [10] and the pressure spring
[11] in the housing.
• Set the insert [12] in the housing [8] using needle-
nose pliers. While doing this, make sure that the
pressure spring [11] is centered; lock the insert in
place by turning it to the right.
•
Insert the filter element [13] into the mount for the
baffle in the container [14].
• Screw the drip tray [14] back into the housing [8];
while doing this, center the filter element and tighten
the drip tray [14] by hand.
Mounting the top part
• Insert the gasket [7] in the hole of the housing so
that the sealing lip points in the direction of the
housing bottom (carefully insert it so that the sealing
lip is not damaged).
• Center the valve piston [10] (already mounted in
place).
• Pull the piston [6] out of the housing [8]. While doing
this, make sure that the valve piston [10] and the
piston [6] are properly centered.
• Insert the spring [5] onto the centering spigot of the
piston [6].
• Screw the upper assembly [3] onto the housing [8]
(while doing this, secure the set screw) and securely
tighten the upper assembly [3].
