32
vertical distance greater than 2 meters.
ATTENTION
If the suction tank is higher than the pump, an anti-siphon valve should be installed to
prevent accidental product leaks. Size the installation to contain the back pressures caused by water
hammering.
ATTENTION
It is a good system practice to immediately install vacuum and air pressure gauges at
the inlets and outlets of the pump which allow verification that operating conditions are within anticipated limits.
To prevent the suction pipes from being emptied when the pump stops, a foot valve should be installed.
CHARACTERISTICS OF THE SUCTION PIPES
The suction pipe must have the following technical specifications:
-
recommended minimum nominal diameter: ¾ ”;
-
recommended nominal pressure: 10 bar;
-
Use pipes suitable for low pressure operation (e.g. with metal core)
CONNECTIONS
ELECTRICAL CONNECTIONS
ATTENTION
IT IS THE INSTALLERS RESPONSIBILITY TO CARRY OUT THE ELECTRICAL
CONNECTIONS IN COMPLIANCE WITH THE RELEVANT STANDARDS.
WARNING
Comply with the following (not exhaustive) instructions to ensure a proper electrical
connection:
-
During installation and maintenance make sure that power supply to electric lines has been turned off.
-
Use cables with minimum sections, rated voltages and installation type that are suitable for the
characteristics indicated paragraph ELECTRICAL DATA and the installation environment.
-
Always make sure that the cover of the terminal strip box is closed before switching on the power supply,
after having checked the integrity of the seal gaskets that ensure the IP55 protection grade.
-
All motors are equipped with a grounding terminal that is to be connected to the ground line of the electrical
system.
PUMP FITTINGS:
The pump is fitted with:
single-phase motor with 2 m power cord
bipolar switch
capacitor
Wired and installed inside the terminal strip box (see chart)
NOTE
The capacitor characteristics are those indicated on the pump label. The switch has the only
function of starting stopping the pump and cannot in any way replace the main power switch required by the
relevant standards.
