5 Maintenance
5.1 Safety
Advice
DANGER
Electrical voltage
Electrocution hazard.
Before opening the cover or working on electrical components, disconnect the
device from power supply. Make sure that the equipment cannot be
reconnected to mains unintentionally.
Installation and maintenance must be carried out by by trained staff only.
Regard correct mains supply.
WARNING
High pressure, environmental hazard
Possible injuries due to ejected parts or oil during maintenance
Do not work on the pressurized oil circuit. This includes work on plug screws. Depressurize
the system before starting maintenance or cleaning.
Avoid environmental pollution during. Use oil pans or similar devices to collect leaking oil.
WARNING
High temperature
Burning hazard
Let the device cool down before starting maintenance or cleaning.
5.2 Maintaining the Cooling Matrix
5.2.1 Cleaning the Cooling Matrix
Due to the fin design, the cooling matrix is resistant to contamination. Generally, brushing the front of the
cooling matrix is sufficient. Nevertheless, if the ambient air carries impurities or other particulates, the
cooling matrix could become clogged quite quickly. In this case we recommend cleaning the matrix on a
regular basis.
-
Disconnect the motor from the mains supply and secure it against re-connection.
-
Let the device cool down.
-
Depressurize the system and unscrew the hoses at the cooling matrix.
-
Plug all ports to avoid oil spills.
-
Secure the cooling matrix against falling down. Loosen the four bolts to dismantle the matrix from the
fan case. Carry the matrix to the cleaning place. Be careful not to damage the fins during transportation
and cleaning.
-
Clean the matrix by blowing pressurised air from the rear side through the fin rows in parallel.
-
Remount the cooling matrix in reverse order after cleaning.
