Safety and Maintenance Instructions

DANGER: Electrical voltage - Electrocution hazard

Disconnect the device from power supply

Ensure the equipment cannot be reconnected to mains unintentionally

Device opened by trained staff only

CAUTION: Hot surface - Burning hazard

Device cooled down before maintaining

CAUTION: High pressure - Risk of injury from ejected parts or oil, environmental hazard from oil

Cleaning and disassembly of the cooler matrix

Due to the design of the cooling fins, the cooler has low susceptibility to dust and dirt

Normally, it is sufficient to clean the front surface with a brush

However, particularly if the air has a high dust and/or oil mist content, the cooling matrices may require regular cleaning

– First allow the cooling matrix to cool down

Disconnect the motor from the mains and secure it against accidental restarting

– Depressurize the system and disconnect the piping to the cooling matrix

Place an oil drip pan below the cooling matrix to collect leaking oil

– Close all connections with plugs to avoid more oil leaking from the matrix

Warning: Ensure the fan is disconnected from power and secured against restarting before starting the procedure

Motor disconnected from power and secured against restarting

Four connecting screws to the box at the tips of the grate loosened

Retaining screw of the fan installed in the motor shaft using glue to secure the screws

WARNING; Danger due to rotating fan

Do not reach into the safety guard!

The device must not be started or operated outside the specifications!

Abrupt flow variation can lead to pressure peaks that may damage the cooler matrix

Make sure that the specifications are not exceeded in this case!
