3.4 Hydraulic connection

Optional:

gauge
Carry out the hydraulic connection as shown in the wiring dia-
gram. Connect the lines stress and vibration free, so typically
using hoses.
Be sure to use suitable lines (with regard to pressure, fluid res-
istance, environmental influences, fire) when connecting to
the hydraulic-, lubrication circuit. Tighten the hose lines with
a suitable torque (see appendix).
Contaminated fluids impact the life of the cooling system, we
therefore recommend a purity class of 23/19/13 per ISO 4406.
When installing the aggregate onto the reservoir cover, the
suction and return pipes immediately go down, vertically, as a
straight pipe. Ensure the thread is sealed well, particularly on
the suction end, and use the included seals for the aggregate.
When installing the aggregate next to the reservoir or a differ-
ent location in the system, the suction- and return bores on
the underside of the aggregate must first be sealed tightly.
With this installation, the suction pipe must not be small than
defined by the present threaded connections. If longer suction
pipes are required, the cross-section of the lines may need to
be larger so as not to continuously exceed the approved neg-
ative suction pressure of max. 0.4 bar.
For proper evacuation of the suction parts it's advisable to fill
the pump or the suction pipe with oil prior to initial start-up
and for long suction pipes. Add some oil to the empty filter
housing will usually suffice. Then briefly run the e-motor with
the filter cover open. If the oil level in the filter housing rises,
the pump is suctioning properly. Now insert the filter element
and close the filter cover. The unit is now ready for use.
On BKF series aggregates the plate heat exchanger connec-
tions are indicated in the nameplate.

The piping to and from the plate heat exchanger must have
shut-off valves. When connecting the pipes, be sure the seals
for the screw connection are clean.
Pipes must generally be run so movement in the lines or pro-
hibited forces are not applied to the plate heat exchanger!

3.5 Electrical connections

DANGER
Electrical voltage
Electrocution hazard.
a) Disconnect the device from power supply.
b) Make sure that the equipment cannot be reconnected to
mains unintentionally.
c) The device must be opened by trained staff only.
d) Regard correct mains voltage.
CAUTION
Electrical voltage
Wrong mains voltage may damage the device.
Installation of the device shall be performed by trained staff
only. Regard the voltage given on the type plate. Make sure
that the cables have sufficient strain relief.
Fusing
Fusing has to be done due to local standards!
Polarity
Take care of the directional rotation of the motor. The rota-
tion direction is indicated on the motor housing "M" and an
arrow.
