IMPORTANT! INSTALLATION STANDARDS
- Do not transport aggressive liquids or liquids
with abrasive substances in a suspension.
- Protect the pump from frost.
- Do not operate the pump dry.
- Never hang the pump up by its water delivery
hose or its power supply cable. Stand it on the
feet provided.
INSTALLATION (FIG. A1)
1 Suction hose (not supplied)
2 Foot valve with filter (not supplied)
3 Delivery hose (not supplied)
4 Non-return valve (not supplied)
5 On-off valve (not supplied)
6 Pump
To limit load losses, the electric pump must be
placed as near as possible to the water level,
while keeping a safe distance.
The suction hose must be rigid and must be
resistant to pressure.
There must be no air
infiltrations, which could prevent the pump
from being primed.
The suction hose must be immersed at least
30cm below the water level.
In order to limit load losses the suction hose
must have a larger section than the suction
duct.
The path of the suction and delivery hoses must
have as few bends as possible.
Important: Use a foot valve with filter (2) (not
supplied) in the suction hose (1) in order to
guarantee instantaneous priming whenever it
is switched on.
In the case of permanent installation it is possible
to anchor the electric pump using the holes on
the support base.
It is recommended to use a non-return valve (4)
on the delivery hose (3) to prevent water ham-
mering. For fixed systems it is recommended to
use an on-off valve (5) on the delivery hose, to
make maintenance operations easier.
STARTING THE PUMP
Fill the pump body and the suction hose with
water as far as the foot valve through the water
cap (Fig.A pos.5).
Open all the valves or taps in the hoses.
Start the pump.
Wait for the pump to be primed.
The use of a foot valve allows the pump to be
primed immediately whenever it is switched on,
without having to repeat the priming procedure.
IMPORTANT! The pump motor is provided
with a device to prevent overloading (thermal
protection). Should this cut in, it is necessary
to remove the cause of the overload and wait
for the motor to cool down before restarting
the pump.
PROPELLER RELEASE (FIG.A2)
!
Warning! Before any maintenance opera-
tions, disconnect the pump from the electric
power supply.
After a long period of disuse due to deposits on
the propeller, the pump could get blocked. In that
case, the pump shaft needs to be turned with
a screwdriver using the cut (where provided)
(fig.A2 pos.8).
MAINTENANCE
!
Warning! Before any maintenance opera-
tions, disconnect the pump from the electric
power supply.
Carry out the following operations in suitable
places and far from electric sockets.
Check and if necessary clean the suction and
delivery hoses and the foot valve (not provided).
Check that the suction and delivery hoses are
perfectly sealed.
Check that the connection cable is in perfect
condition.
!
WARNING DANGER! Do not open the pump
body for any reason. Do not attempt to replace
the pump cables. All maintenance operations
other than those quoted above must be carried
out in an authorised centre.
