WARNING
Danger due to rotating fan
Injuries to the hand may occur. Do not reach into the safety guard!
NOTICE
The device must not be operated beyond its specifications.
NOTICE
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!
5.1 Before starting
– Check that all parts are free of damage, especially the cooling element and fan guard. Do not put a damaged device into op-
eration.
– Check if the two warning labels (rotating parts) on the cooler’s housing are fitted.
– Check the correct connections of oil and power circuits according to chapter „Installation and connection“.
– Make sure that all valves or other parts in the cooling circuit, which have to be opened, are opened.
5.2 During starting
First, check that the motor is proper electrically connected and the fan rotates counter clockwise when looking from the motor’s
side.
CAUTION
Hot surface
Burning hazard
Let the device cool down before maintaining.
CAUTION
High pressure
Hazard of injury due to flung off parts or oil, environmental hazard due to oil.
a) Before starting any maintenance or repair to the oil circuit, make sure that the device
is depressurized. This applies to the threaded plugs as well.
b) Avoid environmental pollution (oil spills) during cleaning or maintenance of the oil
circuit.
c) Use drip pans.
Noise level
The coolers, which are supplied with an additional circulation pump, have a low noise. If the noise level increases significantly
over the listed value, this could be caused through improper installation of the cooler, specially of the suction line. The technical
consultants from Bühler Technologies GmbH will be happy to assist you.
