Installation and Servicing Instructions:
ULDC Air/Oil Cooler
These instructions should be observed prior to installation of
the PARKER ULDC cooler.
Mounting
The PARKER coolers permit both horizontal and vertical
mounting. The conduit entry of the DC motor must always be
turned downwards. To prevent personal injury, always secure
the cooler adequately. The distance from the nearest
obstruction should not exceed half the height of the cooler
core.
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 when possible. When this can not be
done, install the cooler in the system return line. Avoid
linking to systems that could cause pressure spikes in excess
of 200 psi. PARKER shall not be held responsible for any
consequences due to modification and/or variation with regard
to connections.
Electrical Connection
PARKER ULDC cooler is supplied with a 12V or 24V DC
motor. Connect the power source to the cooler as illustrated
below. For protection of the motor, always use a relay.
The circuit diagram below should be applied when connecting
a cooler equipped with a switch box.
In case where the cooler is provided with a thermoswitch, use
a relay if the current lULDC is greater than:
10 A
at
12V DC
5 A
at
24V DC
Prior to Start-Up
Check cooler core and fan guard for damage.
Check that the cooler is provided with a caution label for
fan rotation
Check that the cooler is correctly connected according to
the above. PARKER shall not be held responsible for any
consequences due to variations.
