6. ALARM SYSTEM (supplied only on request for Fekabox 200 l – Fekabox 280 l)
For the parts references, see the diagrams on pages 18-19.
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
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.
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 22).
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.
7.3 It is recommended to clean the system at least once a year with running water, operating the pump
repeatedly.
