C. Disconnect the 1” hose from the minimum pressure valve.
D. Disconnect the 1/4” tube from the elbow on the separator tank lid.
E. Disconnect the 1/4” tube from the elbow on the discharge pressure regulator valve.
F. Disconnect the 1/4” tube from the elbow on the blowdown valve.
G. Disconnect the 1/4” tube from the straight connector on the oil return line.

I.
Lift and remove the lid from the package.
J. Remove the separator element.
K. Install a new element.
L. Reinstall the separator tank lid.
M. Reinstall the eight 5/8” bolts.
N. Uniformly tighten the bolts in a crisscross pattern to a torque of 220ft-lb.
O. Reconnect hose and tubes and ensure they are correctly located and tightened properly.
P. Start machine and check for any leaks.
Substitute filters may have inadequate working pressure
limits, resulting in filter leakage or rupture. Replacement
filters must be the same quality and type as the original Boss
Industries, Inc. separator element.
When disconnecting hose and tube, be sure to note the
location to ensure there is no confusion when
reconnecting.
Note the location of the separator tank lid so that it can
be reinstalled in the same orientation.
The separator element flange must have a gasket on each side
to seal the lid on one side and the vessel on the other. The
staple in each gasket acts as a static ground and must not be
removed.
The separator tank lid has a pick-up tube installed and
damaging or moving the tube will affect the machines.
