6.1 Pre-set system
This type of system requires only a float supplied on request,
which is fixed inside the (empty) tank using the cable clamp (87)
already installed inside the tank.
Strictly respect the cable length between the cable clamp and
the float, indicated in figure C.
Pass the float cable out of the tank, through the pre-set fairlead
(149), tighten the ring nut and connect the cable to the control
panel following the instructions provided with the panel.
The signal may be visual and/or acoustic, depending on whether
the control unit is connected to a warning light and/or a 230V-ac /
10 Watt siren, also supplied on request.
6.2 AS1 System (supplied only on request)
The AS1 alarm system, supplied on request complete with
instructions, is composed of:
- an electronic control unit with reserve charge
- a float
The float is fixed to the inside of the (empty) tank, using the
cable clamp (87) already installed inside the tank.
Strictly respect the length of the cable between the cable
clamp and the float, as indicated in the figure C.
Pass the float cable out of the tank through the preassembled
fairlead (149), tighten the ring but and connect it to the control
box.
Before filling the tank, manually operate the float to check functioning of the alarm system, previously
connected to the mains in accordance with the instructions supplied with the AS1.
6.3 Testing the alarm system
Make a complete test of the system with clean water, checking that the alarm system intervenes only in the
case of pump breakdown or lack of current in the mains.
To do this, proceed as follows:
1. Fill the tank up to pump intervention level and interrupt the supply to the pump. In this situation the
alarm system must not intervene.
2. Continue filling the tank until the alarm system intervenes Check that in this condition the water level is
a few centimetres lower than the MAX emergency level (figure on page 27-28).
If this condition does not occur, shorten the length of the cable between the cable clamp and the safety float.
7. MAINTENANCE
7.1 After starting up the plant, it is advisable to inspect and clean it, especially the no return valve, about
every three months. This interval may be increased after the first inspections have given a favourable
outcome.
7.2 Clean the pump accurately, removing any foreign bodies stuck in the intake grille and check that the
float moves freely. If necessary, remove the pump from the tank.
It is recommended to clean the system at least once a year with running water, operating the pump
7.3
repeatedly.
