- It is also recommended to install a filter for
particles at the end of the tube or hose to avoid dirt
particles entering the pump and blocking it.
5.2.2. IMPULSION CONNECTION
Connect the impulsion tube using a 1¨ male connector
to the aspiration of the pump.
If you use a hose instead of a tube for aspiration
make sure that the hose is adequate and depression
resistant.
If the installation is fixed, we recommend using a
flexible metallic hose to avoid transmitting noise and
vibrations to the installation.
5.2.3. PRIMING THE PUMP
The pump of this machine must be primed the first
time it is turned off after its installation.
For water to be pumped, the deposit of the pump
must always be full of water. NEVER work with the
machine dry.
5.2.4. ELECTRIC CONNECTION
It is obligatory to connect the machine to a mains
switch protected by a residual differential equal
to or less than 30mA. Electricity tension should
be 230v, frequency 50Hz and have a magnet and
thermic switch between 10A-16A.
When using a cable extension, make sure that
its minimum section is 1.5mm2 and no longer
than 25 metres, always unrolled and adequate for
outdoor use. The use of the cable extension adequate
for outdoor use, reduces the risk of electric shock.
Place the cable extension in such a way that it does
not touch the water and that it will not fall into the
water when the pump starts working. The cable
extension must always be well away from the water
and dry.
Connect the pump to the mains.
6. MACHINE USAGE
Use this machine only for jobs for which it has
been designed. The use of this machine for any other
jobs is dangerous and can cause dangers to the users
and/or to the machine.
Do not rely solely on the security elements of the
machine.
6.1. CHECKING POINTS PRIOR TO START UP
It is important to check that all parts are well
tightened. If you detect any anomaly, stop the machine
straight away and check the machine carefully. In case
of any water leakages, check the installation carefully.
Never carrying on working if the machine is not
working correctly.
6.2. START UP AND STOPPAGE
6.2.1. FIRST START-UP AFTER INSTALLATION (SELF-
PRIMING):
1. Open the circuit stopcocks that exist on both the
suction and delivery side.
2. Open a tap in the installation circuit to allow the air
and water driven by the pump to escape.
