Installation

The cold Water booster set is despatched mounted on a wooden pallet and covered in a protective film, it is

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.

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

The cable used for the incoming supply must be of adequate size to carry the motor full load

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

Water supply connections

Connect the incoming water supply to the break tank ball valve. The outlet of the tank will already be connected

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

to the booster set suction manifold. The tank will include a class AB air gap (Category 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 nuisance
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.
