4.2 Transport
Avoid subjecting the products to needless impacts and collisions.
4.3 Weight and dimensions
The adhesive plate on the packaging indicates the total weight of the pump and its dimensions.
5. WARNINGS
The pumps must never be carried, lifted or allowed to operate suspended from the power cable; use the
handle provided.
The pump must never be allowed to run when dry.
The pump must be positioned so that the holes on the suction side cannot be partially or totally clogged by dirt.
The sealing device contains lubricant which is non-toxic but which may alter the characteristics of the water, in the case
of pure water, if the pump were to have any leaks.
The pump has a thermal overload safety device. In the event of any overheating of the motor, this device automatically
switches off the pump. The cooling time is roughly 15 to 20 minutes, then the pump automatically comes on again. If
the overload cutout is tripped, it is essential to identify and deal with the cause of the overheating. See Troubleshooting.
6. INSTALLATION
The electrical system must be compliant with local norms.
Screw on the elbow with hosetail fitting provided in the packaging. For the dirty water version only the fitting for 1''1/2 pipes;
if you want to use a pipe with a larger diameter, change the elbow coupling. Use a pipe tightening clamp to secure the pipe
to the fitting.
It is advisable to use pipes having an internal diameter of 38 mm (1.5") to avoid the decrease of pump performance
and the possibility of blocking.
If the bottom of the trap where the pump is to be placed is particularly dirty, a raised support should be provided so as
to avoid blocking of the suction grid (Fig.1)
Totally immerse the pump in the water.
Ensure that the minimum dimensions of the trap in which it is housed are as follows:
Min. base dimensions (mm) 400x400 (15.75"x15.75") / Min. height (mm) 400 (15.75")
Pay attention to ensure that the float is free to move, leave at least 5 cm (2") from the wall of the trap.
The dimensions of the trap 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
There are two operating modes:
MANUAL (A)
Although they have a float, the pumps can be used in manual mode Fig.2
1)
Fix the float switch so that it remains vertical above the pump (with the cable below) (a). As long as the float switch
remains raised, the pump keeps operating irrespective of the water level.
2)
Insert the plug of the power cable in a 115–120V power socket.
3)
The pump will start up; ensure that it is immerse in the liquid to be pumped.
Pay attention because the pump will not switch off automatically once it reaches the minimum level; it must be switched
off manually by the user, either by taking the power out of the socket or by lowering the float (automatic operation).
The maximum suction level is reached only during manual operation because, in automatic operating condition, the
automatic float switch stops the pump before it reaches that level.
AUTOMATIC (B)
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 (Fig.3).
1)
Leave the float free to move.
2)
Insert the plug of the power cable in a 115–120Vpower socket.
3)
When the float reaches the ON level the pump will start and will continue operating until it reaches the OFF level.
