4.
Test the HPU.
A.
Remove the 1/2” NPT pipe plug and install the breather in the
reservoir cover.
B.
Make sure all the pressure, return, and drain port caps are in
place.
C.
Press the
Start
button (be sure the
Stop
button is released).
D.
Check that the output pressure is less than 6.9 MPa (1000 psi).
E.
Press the
Stop
button.
5.
Connect the hydraulic lines.
See
on page 13 to determine the locations
of the hydraulic connections to the HPU. See the following table to
identify the size of each hydraulic connection.
NOTE
Some maintenance procedures require you to set the HPU for a no-
flow condition (where no fluid is flowing to other hydraulic
equipment). You may want to consider plumbing in a bypass circuit
in the system hydraulic lines.
