Preparation for Use and Installation
The 108/118 Series DC motors are available in two types:
Permanent Magnet (PM) and Series Wound (SW).
The 165/175 Series uses DC Permanent Magnet (PM) motors.
Motor Ratings (nominal):
• 108/118 Series AC motor 115/230 VAC:
246 W
• 108/118 Series DC PM 12, 24, 36 VDC:
250 W
• 108/118 Series DC SW 12, 24 VDC:
425 W
• 165/175 Series DC PM 12, 24 VDC:
800 W
The 108 and 165 Series Power Units provide two ports, marked
UP for the left hand port and DN for the right hand port. In
standard power unit configurations, the UP port is the pressure
port for Single Direction models and the DN port is the return
port. For Reversible models, the UP and DN ports alternate as
pressure ports depending on the rotation of the electric motors.
See below:
The 118 and 175 Series Power Units provide a flat surface for
mounting a manifold. As in the 108 and165 Series versions,
these ports are also marked UP and DN. See below:
Acceptable fluids for 108/118/165/175 Series Power Units:
• Standard Automatic Transmission Fluid (ATF)
• Most mineral based hydraulic fluids
Viscosity range: 32-64 cSt (150-300 SSU) at 38°C (100°F).
Please contact Parker Oildyne to discuss any alternate fluids.
Parker Oildyne takes no responsibility if unapproved
alternatives are used.
Temperature Ranges for 108/118/165/175 Series:
Operating:
-7 to +60°C (+20 to +140°F)
Storage:
-7 to +60°C (+20 to +140°F)
Please contact Parker Oildyne for usage outside of this range.
108/118 and 165/175 Series Power Units should be installed
indoors in a clean environment.
108/118 and 165/175 Series Power Units are designed for
Intermittent Use Only.
Only under very limited circumstances can a 108/118 Series
Power Unit run continuously. These are when:
• The 108/118 Series 12 VDC Permanent Magnet motor is
drawing less than 12.6 A
• The 108/118 Series 24 VDC Permanent Magnet motor is
drawing less than 9.6 A
The Series Wound motors are not designed for continuous duty.
The 108/118 Series 115 VAC and 230 VAC motors are capable
of operating a maximum of 5 minutes on continuously. The
AC motors must then be off until they have cooled down to
the ambient temperature. This could take 90 to 120 minutes,
depending on the ambient conditions. The 165/175 Series PM
motors are not intended for continuous operation. For Motor
Duty Cycle Characteristics, see pages 17 - 20.
The 108/118 Series and 165/175 Series Power Units are
intended to be used in a variety of applications, specified by the
customer, where pressurized hydraulic fluid is required to move
an actuator, charge an accumulator or supply test equipment.
Parker Hannifin Corporation takes no responsibility for the
safety of any unit if it is not used for the intended purposes
detailed in this Instruction Manual.
Some examples of abnormal uses of this unit would include:
• Use of unit with higher pressure than that for which it was
intended
• Use with a higher or more frequent duty cycle than that for
which it was intended
• Use with higher or lower voltage than required for optimal
use
• Use in a mounting orientation other than that for which it was
designed
• Use of fluids not recommended
Preparation for Use
Unpacking and Checking
All units were carefully packed in containers or boxes, and may
or may not be on skids. In any case, do not remove anything
from the skid or any packaging until it has been carefully
checked for damage that may have occurred in transit. Report
all damage immediately to the carrier and send a copy to the
vendor.
All open ports on the power unit were plugged at the factory to
prevent the entry of contamination. These plugs must not be
removed until just before piping connections are made to the
unit.
Storage
If the unit is not going to be installed immediately, it should be
stored indoors, covered with a waterproof sheet, with all open
ports plugged. If long term storage is expected (six months or
more) we recommend filling the reservoir completely with clean
hydraulic fluid to prevent the entry of moisture.
Installation
Locating Power Unit
The unit should preferably be installed indoors in a clean, dry
environment with an ambient temperature of 16 to 37°C (60 to
100°F). However, if this is not possible, mount the power unit in
a location that is protected from direct liquid contact.
Parker Oildyne power units should not be installed where there
is a risk of objects falling from overhead or where there is any
risk of impact with external objects.
Mounting the power unit
108/118 and 165/175 Series Power Units are factory assembled
complete and tested based on the model codes ordered by
the customers. They are also assembled specifically for the
