PIPES
Secure all pipes to support so that they do not carry
on stress, strain or vibration to the pump.
The inner pipe diameter depends on the capacity
required. If possible, diameter has to enable a liquid
speed not higher than 1.5m/s during suction and
3m/s during delivery. The pipe diameters never have
to be smaller than the pump connections.
The suction pipe must be perfectly airtight and be
led upwards in order to avoid air pockets. For suc-
tion operation fit a strainer-equipped valve, which
must always be immersed.
For suction from a storage tank fit a check valve. For
positive suction head operation fit a gate valve. Fol-
low local specifications if increasing network pres-
sure. Fit a gate valve into the delivery pipe to adjust
delivery, head, and absorbed power.
Install a pressure gauge. With a geodetic head at
outlet over 15m fit a check valve between the pump
and the gate valve in order to protect the pump
from water hammering. Ensure the inner sides of
the pipes are clean before connection.

ELECTRICAL CONNECTION

Electrical connection must be carried out by a qual-
ified electrician in compliance with local regulation.
The unit must be properly earthed (grounded).
Position the terminals following the instructions
written on in the plate, which is placed inside the
capacitor box. Install a device for disconnection
from the supply, having a contact separation of
at least 3mm in all poles. Single phase pumps are
supplied with a capacitor connected to the ter-
minals and with inset thermal protector for 220-
230V - 50Hz.
START-UP
Check that the shaft turns by hand. For this pur-
pose the smaller pumps have a screwdriver notch
on the ventilation side of the shaft end. Never run
the pump dry.
Start the pump after filling it up with liquid
through the relevant priming hole.
When operating under positive suction head, fill
the pump by opening the suction gate valve slow-
ly and completely, keeping the delivery gate valve
open to release the air.
With three phase motor check that the direction
of rotation is as shown by the arrow on the pump
casing; otherwise reverse the connections of the
phases.
Check that the pump works within its field of per-
formance, and that the absorbed current shown
on the name plate is not exceeded.
Otherwise adjust the delivery gate valve, or the
sitting of any pressure switches.
MAINTENANCE
When the pump is not used, empty it completely if
freezing may be expected.
Before restarting the pump, check that the shaft
is not jammed from incrustations or other causes
and fill the pump casing completely with liquid.
CAUTION: disconnect the mains before any ser-
vicing operation.
