Hydraulic Connections
The accumulator ports are identified in Figure 3 below.
Connect hydraulic power source to pump port. Enerpac recommends installing
an FL2202 high pressure filter between the coupler and hex fitting to insure that
no contaminants enter the accumulator block. Use
BFZ-2045 to connect the filter to the accumulator block.
Use the optional retract port for systems with double-acting cylinders. Order
Enerpac AH-652 male coupler half for retract port.
NOTE: Advance port comes with a male coupler half. Order Enerpac AR-650
for mating female half.
