NOTICE
!
The actual pressure loss increases due to bends and fittings. In some cases it might
be necessary to determine the final shape of the suction line on site under specific
conditions.
CAUTION
Damage to the cooling system in case of high pressure
To avoid damage to the cooling system make sure that the maximum pressure of the pump
is never exceeded.
Do not shut off or curb the system at the pressure side.
3.4 Electrical
connection
DANGER
Electrical voltage
Electrocution hazard.
Installation and maintenance must be carried out by by trained staff only.
Regard correct mains supply.
Fusing has to be done due to local regulations. Take care of the rotation direction of the fan which is
counter clockwise when looking from the motor side. Depending on the specifications (230°V or 400°V) the
motor is prepared for star or delta connection.
The pin assignment is shown in the cover of the terminal box.
4 Operation
4.1 Before
starting
¾
Check that all parts are free of damage, especially the cooling element and protective grating.
¾
Check if the two warning labels (rotating parts, vents) are fitted on the cooler’s housing.
¾
Check the correct connections of oil and power circuits according to chapter 3.
¾
Make sure that all valves or other parts in the cooling circuit which have to be opened are opened.
4.2 First start up
Check that the fan rotates counter clockwise when looking from the motor’s side. If not, change the
electrical connection.
Noise level:
The FGSL is supplied with a low-pressure pump producing low noise. If the noise level
increases significantly check if the suction line has the right dimension and that the pump works in the
appropriate temperature / viscosity range. Please do not hesitate to ask Bühler Technologies GmbH for
technical advice.
