The hydraulic power unit requires three (3) phase 460 volts AC. The motor can be
requested for 230/220 volts but 460 provides
better performance. The hydraulic hoses to the
cylinder can be lengthened to 50 feet without
affecting cylinder operation, but the five (5)
control hoses should remain at 25 feet as
longer hoses will adversely affect cylinder
reaction time. The top connections are for the
control hoses, those on the side are for
cylinder hoses. Electrical is connected through
the top of the control box. The connections and
control switch should be easy to reach. The
fluid temperature gauge and filter condition
indicator is
on the
opposite
side and
will need to be seen and serviced. Mount the
power unit (step #2) securely by either bolting or
welding it to the rig floor. The unit requires
ventilation and secure routing of the five (5) control
hoses and two (2) cylinder hoses.
The control box should be mounted where 1) it’s
convenient to the driller and 2) the 25 foot control
