Hydraulic connection
Connect the cooler as illustrated below using hydraulic hoses both to and from the
cooler. We recommend mounting in a separate cooling circuit; In case this is not
possible, install the cooler in the system return line. Avoid linking to systems that
could yield pressure spikes greater than 200 psi. Parker Hannifin Corporation shall
not be liable for the consequences of any modification and/or variation with regards
to connections.
Installation and Servicing Instructions: ULRM Rear-Mount Oil Cooler
NOTE: These instructions should be strictly observed prior to installation of ULRM cooler
Mounting
The ULRM oil cooler permits both suspended (vertical) and
foot (horizontal) mounting. To prevent personal injury, always
secure the cooler properly. The distance from the nearest wall
should not be less than half the height of the cooler core.
Motor Seal
See chart for size of motor opening based on the motor frame size. The required length
of the e-seal is the circumference of this opening. The values below represent an
approximate length only. It is recommended to cut the seal slightly longer than the
required length then adjust once it is mounted to the housing.

Cleaning the cooler core
The easiest way to clean the air fins of the core is by using compressed air. Fouling
can be dealt with using a high-pressure washing system and a degreasing agent.
Flush with water afterwards.
Caution: When using a high-pressure washing system, point the jet parallel to the air
fins. The cooler core should be cool before cleaning.
To clean the inside of the core, connect the core to a closed circuit and flush the
inside with degreasing agent. After cleaning, the core should be flushed with the
same fluid as used in the system itself.
Miscellaneous
· Contact Parker Accumulator & Cooler Division when using fluids that are very
different to normal hydraulic fluid (ie. high viscosity fluids) or in extreme conditions.
Rotating the cooler core
The core can be rotated in 90 degree intervals to add plumbing flexibility. Detach
core from housing by removing 4 bolts. Dispose of used foam strips attached to
housing. Rotate core and apply new foam strips to housing, making sure to cover
unused bolt holes while making sure foam does not leave any air gaps between core
and housing. Replace 4 bolts and washers and tighten to housing using manual
wrench.
Prior to start-up
· Check the cooler core for damage
· Check that the cooler is correctly connected (see above). Parker Hannifin
Corporation shall not be liable for the consequences of any variation.
