Xylem O&M Mini V Series Variable Speed - Manual (Page 2)

Installation
The cold Water booster set is despatched mounted on a wooden pallet and covered in a protective film, it is
recommended that the unit be retained in the protective packaging until the product is to be
installed. The unit will arrive pre-packaged and wired ready for installation. This product has
been fully run tested at our works under simulated site conditions. The unit should be thoroughly
checked for physical damage that may have been caused during transit. If the unit is found to
have damage it must be reported immediately and should not be installed. The unit should be sited
in a ventilated, dry frost free position also ensuring adequate room for general maintenance and service. The set
should be fixed in position directly to the floor, if vibration separation is required then cork mats should be
used supplied by others.
The water tank is constructed to have a weir slot as required by the water bylaws to prevent back flow
contamination, if the inlet ball valve suffered a catastrophic failure the overflow may not be able to keep up
with the inflow in which case excess water will be ejected through the weir slot and onto the plant room
floor, if this is not acceptable then consideration should be given to fitting the booster set onto a try with
overflow to drain.
Never run pumps dry
Ensure the pumps are filled with water before switching the power on.
Electrical connections
The electrical connections must be carried out by a competent electrician in accordance with local
regulations.
The cable used for the incoming supply must be of adequate size to carry the motor full load
current of all pumps as they are able to operate at the same time. Motor ratings are shown on the
set duty plate. All non power cable should be limited to 1.5mm².
All connections must be made using the appropriate wiring drawings for the equipment being
installed; with particular attention being paid to the supply voltages. The supply voltage is shown
on the set duty plate.
Never operate this product with isolation panels removed or the control panel door in the open
position. These Sets are fitted with variable speed drives which include large capacitors so wait at least
8 minutes after the supply has been removed before opening or removing covers.
It is essential that this equipment is earthed to the building earth system.
All metal parts must be earth bonded directly to the building earth system.
Electrical data TKS/GTKS
Note: whilst the input to the
inverter is Single phase, the
output to the motor is Three
phase.
Water supply connections
Connect the incoming water supply to the break tank ball valve. The outlet of the tank will already
be connected to the booster set suction manifold. The tank will include a class AB air gap (Cate-
gory 5 protection) the tank will also include a low level float switch connected to the booster set to
protect against dry running. Connect the 22mm warning pipe to a position where a discharge will cause a nui-
sance and be remedied. Connect the overflow pipe to drain.
When the tank has been filled check the water level and adjust ball valve as necessary.
Ensure the tank is thoroughly flushed through before the set is put on line.
It is the responsibility of the installer to ensure that the overflow is able to keep up with the incoming
water volume; if this is not the case then a pressure reducing valve should be fitted to reduce the incoming
mains water volume.
