a) Connect the hydraulic pressure and drain lines to the hydraulic fluid distribution system or directly to
a hydraulic device. Use hydraulic line or hose that is rated to handle the maximum hydraulic pressure
of the HPU.
Note:
If check valves are installed on the pressure or return ports, an extension tube might be required
on the drain port to aid in final connection to the system drain line.
b) An appropriate shutoff valve should be installed between the water source and HPU.
c) Connect the water supply to the HPU Water In port. Connect the Water Out port to your drain line.
d) A regulating valve must be adjusted according to your water temperature. For a description of how to
set the water regulating valve see, the “Changing the Water Flow” procedure.
The water supply must also be capable of maintaining water flow at a rate listed in the following table.
