4.2.3 Loading Operation: Installation above head and below head
With reference to its position with respect to the water to be pumped, the installation of the system may be defined "above head" or "below head".
n particular the installation is defined "above head" when the pump is placed at a level higher than the water to be pumped (e.g. pump on the
surface and water in a well); vice versa it is "below head" when the pump is placed at a level lower than the water to be pumped (e.g. overhead
cistern and pump below).
Installation "above head": with the aid of the accessory tool (Fig.3_ point 5) or with a screwdriver, remove the filling cap which, for the horizontal
configuration, is the one on Face F (Fig.1). Fill the system with clean water through the loading door, taking care to let the air out. The quantity of
water with which to fill the system must be at least 1.5 litres. It is recommended to fit a non-return valve at the end of the suction pipe (foot valve)
so as to be able to fill it quickly too during the loading operation. In this case the quantity of water necessary for the loading operation will depend
on the length of the suction pipe (1.5 litres + ...).
Installation "below head": if there are no check valves between the water deposit and the system (or if they are open), it loads automatically as
soon as it is allowed to let out the trapped air. So slackening the filling cap (Face F – Fig.1) enough to vent the air allows the system to load
completely. To slacken the cap, use the accessory tool (Fig.3_ point 5) or a screwdriver. You must survey the operation and close the loading
door as soon as the water comes out (however it is recommended to fit a check valve in the section of the suction pipe and to use it to control the
loading operation with the cap loose). Alternatively, in the case where the suction pipe is intercepted by a closed valve, the loading operation may
be carried out in a similar way to the one described for installation over head.
5. COMMISSIONING
– Maximum working pressure 8 bar.
– The intake depth must not exceed 8m.
5.1 Electrical Connections
To improve immunity to the possible noise radiated towards other appliances it is recommended to use a separate electrical duct to supply the
product.
The line voltage may change when the electropump is started. The line voltage may undergo variations depending on other devices
connected to it and on the quality of the line.
It is recommended to carry out installation as indicated in the manual, in compliance with the laws, directives and standards in force in the place
of use and depending on the application. The product contains an inverter inside which there are continuous voltages and currents with high-
frequency components (see table 1):
