6. HYDRAULIC CONNECTIONS (FIG.3)
Before proceeding with hydraulic connection it is essential to install a non-return valve in the pump´s inlet
or outlet.
The device must be connected in vertical position (FIG.3), the inlet port ( G1” male) directly to the main pump
discharge and the outlet port (G 1” male) at the main network.
It is compulsory to use an hydropneumatic tank in order to avoid continuous start-stops due to the deterio
-
ration of taps, valves, ... and also to prevent "water hammer" in installations with valves of wide diameter.
7. ELECTRIC CONNECTION (FIG.1 - FIG.2)
Before doing manipulations inside the device, it must be disconnected of the electric supply and after disa
-
bling, wait for 2 minutes in order to avoid electrical discharges.
Use cables type H07RN-F with section enough to the power installed:
•
Power supply: s ≥ 1,0 mm²(max.2,5 mm²).
•
Motor supply: s ≥ 1 mm² (max.2,5 mm²) depending on the cable length (FIG.2).
Verify if the power supply is 127-230 V. Dismount the front cover and carry out the connections according to
the indications of FIG.1.
Do the power supply connection (being sure there is a good earth connection): N
L
Do the connection by mean of magnetothermic switch in OFF mode.
The earth conductor must be longer than the others. It will be the first one to be mounted during the as
-
sembly and the last one The earth conductor must be longer than the others. It will be the first one to be
mounted during the assembly and the last one to disconnect during disassembling.
Do the pump connection: V W .
WARNING! Wrong connections could spoil the electronic circuit. The manufacturer declines all responsa
-
bility in damages caused by wrong connection.
