H. Unit Installation
Flush the system through 10 micron full flow filters prior to
installing the servo valve. A flushing plate can be manufac-
tured. (See Figure 6.) The plate passes the fluid directly to
the tank port. Continue flushing until new filters show no sign
of contamination. It may be necessary to change the system
fluid. If so, filter the new fluid as it is poured into the reservoir
and then flush the system as described above. After the
system is flushed, remove the flushing plate and install the
servo valve. Torque the mounting screws to a maximum of
112 lb.in.
