Supply and Return Connections
108 Series ports:
• 7/16-20 SAE-4 o-ring type (model code -1)
• 7/16-24 inverted flare (model code -2)
• 1/8 in NPSF (model code -3)
• 1/8 in BSPP (model code -4)
165 Series ports:
• 7/16-20 SAE-4 o-ring type (model code -1)
• 1/8 in BSPP (model code -4)
Fluid connectors and conductors installed by the customer
should be selected based on an acceptable safety margin for
the maximum pressure required in the application. 108/118
Series Power Unit are capable of up to 207 bar (3000 psi);
165/175 Series Power Units are capable of up to 241 bar (3500
psi). SAE-4 ports are recommended when selecting a power
unit due to the integrity of the o-ring seal. 1/8 in NPSF ports will
use standard 1/8 in NPT tapered fittings.
Use great caution
when installing these tapered fittings as the aluminum
adapter casting will crack if the fittings are overtightened.
Use of a thread sealant, whether a PTFE tape or paste, is
permitted, however, ensure neither the excess tape nor paste is
allowed to enter the fluid passageways as these contaminants
could cause problems.
The 118/175 Series versions will not have connectors or
conductors installed directly, but, instead, will have a customer-
supplied manifold bolted to the flat port surface. Fluid
connectors and conductors will be installed into the customer-
supplied manifold.
Line sizes should be determined based on oil flow, operating
pressure and allowable pressure drop between the power unit
and actuator.
Warning
Check to insure that the proper rated hose or pipe is used on
pressure lines.
One of the key ingredients for good service and long life from
a hydraulic system is cleanliness. Because most most dirt
infiltrates a hydraulic system during installation, we recommend
the following:
a) All open ports on the power unit, cylinders, etc. must remain
plugged with tape or plastic plugs until just before the hydraulic
connections are made.
b) All interconnecting tubing, pipe, or hose should be clean, and
free of rust, scale and dirt. The ends of all connectors should be
plugged until just before they are to be installed in the system.
c) All openings in the reservoir such as the filler/breather or
access end covers holes must remain closd during installation.
Hydraulic Fluids
Follow all vendor-supplied instructions for safe handling, use
and disposal of the fluid selected for operation in this power
unit.
It is strongly recommended that the customer have available the
MSDS for the fluid chosen for use in the 108/118 and 165/175
Series Power Units. Follow all instructions should the fluid spill
or come in contact with an operator.
It is critical that the reservoir be filled with an approved fluid
prior to startup of the power unit. Any system failures due to
improper fluids being used or operating without the reservoir
being full of an approved fluid will result in voiding the warranty.
The reservoir must be filled with clean fluid through the filler
