4. INSTALLATION

NOTE:
Improper installation can cause equipment damage. HYDAC coolers must
be installed by properly trained and qualified personnel. Any operating
personnel must be instructed according to this manual.
No cutting or drilling operations are necessary in order to install the cooler.
The cooler should preferably be installed vertically on the mounting feet.
This is the recommended configuration. Other configurations must be
discussed with HYDAC.
If strong vibration is expected during operation (particularly on mobile
applications), the cooler must be decoupled from the machine as far as
possible with suitable shock absorber elements and by using flexible
connections (see the Accessories Catalogue).
The cooler should be fixed to a stable surface, using the bolt holes in the
feet or in the cooling element.
Unrestricted airflow should always be ensured. Please refer to the
dimensions W1 & W2 in the product catalogues for recommended
clearances for the air inlet and outlet.
In closed rooms sufficient ventilation must be provided to prevent a rise in
room temperature as a result of heated air dispelled by the cooler.
In case of doubt, ventilation between the cooler and the outside air should
be assured by installing ventilation ducts. The size of the ducts must
correspond at least to the frontal area of the cooler.
Inappropriate location of the cooler could
reduce cooling capacity and increase noise level.
If mounted in a contaminated environment (dust, oil, etc.) dirt will
accumulate on the cooling surface, therefore reducing cooling
performance. In this case frequent cleaning must be carried out.
Connect the cooling element using flexible hydraulic hoses and hydraulic
threaded connections. The inlet and outlet of the hydraulic connections are
clearly labeled (IN & OUT). Make sure that all connections and hoses are
sized according to the working parameters: pressure, flow, temperature
and type of fluid.
Please refer to Table 1 for the max. permitted torque rating on all the
available threaded connections.
If the unit is installed outside, sufficient protection against the weather
should be provided; electric motors in particular must be protected against
climatic influences.
