
To avoid obstruction of the suction passages, it is recommended to check periodically that no dirt has accumulated in
the collection cistern (leaves, sand, etc.). It is advisable to leave a minimum distance of 20 cm (8") to avoid clogging
of the suction grid (Fig.2)

Insert the plug in a socket, main power must to be 115-120V.

the pump must be activated only if immersed in water. Consider a minimum submersion of 12 cm (4.7"). If the water
is finished the pump must be stopped immediately, taking the plug out of the socket.

The pump must be placed in a stable position inside a collection cistern or in the lowest part of the place where it is
installed.

Ensure that the minimum dimensions of the collection cistern in which it is housed are as follows:
Min. base dimensions 130x130 mm (5.12"x5.12") / 800mm (31.5") Fig 2

The dimensions of the cistern must always be in relation to the quantity of water arriving and to the flow of the pump,
so as not to subject the motor to excessive starts/hour; it is strongly recommended not to exceed 20 starts/hour.
The pump must be installed in vertical position!

7. ELECTRICAL CONNECTION

The length of the power cable on the pump limits the maximum depth of immersion in use of the pump.
Follow the indications on the technical data plate and in this manual, table 2.

8. START-UP

The float switch automatically controls the pump starting and stopping (ON/OFF) depending on its position.
The models with a float switch are started automatically when the water level rises and will switch off when the required
minimum level is reached
1) Leave the float free to move.
2) Insert the plug of the power cable in a 115-120V power socket.
3) When the float reaches the ON level the pump will start and will continue operating until it reaches the OFF
level.
The best working condition is with the pump be completely submersed in water.
Anyway the motor's cooling system allows the use at the minimum suction height for very short periods (50 mm/
The pump is equipped with a stainless steel anti-deposit filter.

9. PRECAUTIONS

RISK OF FROST: when the pump remains inactive at a temperature lower than 32 F, it is necessary to ensure that there
is no water residue which could freeze, causing cracks in the plastic parts.
If the pump has been used with substances that tend to form a deposit, or with water containing chlorine, rinse it after
use with a powerful jet of water in order to avoid the formation of deposits or encrustations which would reduce the
characteristics of the pump.

10. MAINTENANCE AND CLEANING

In normal operation the pump does not require any type of maintenance. In any case, all repair and maintenance work
must be carried out only after having disconnected the pump from the supply mains. When restarting the pump, ensure
that the suction filter is always fitted so as not to create the risk or possibility of accidental contact with moving parts.
