Check that the voltage is not above or below 10% of the voltage
indicated on the equipment board.
The pressurizer pump has two different selectors:
1. Operation Mode Selector
I By selecting this mode the pressurizer pump will operate
manually.
II By selecting this mode the pressurizing pump will operate
automatically.
O Selecting this mode will keep the pressurizer pump off.
2. Operation Speed Selector
You are installing a pressurizing pump with 3 speeds, which you
can select depending to your water flow needs and according
to the curves chart. In this way we want to maximize the energy
consumption of your house.
To obtain the lowest flow it is necessary to position the selector
in option 1.
For an average flow you have to select speed 2.
If you want the largest available flow, locate the selector in
position number 3.
The values of maximum flow, maximum pressure and electrical
consumption shown in the table of technical characteristics
are based on operating the pressurizing pump at the maximum
speed.
The pressurizing pump is designed to work in open circuits of
pipes for clean water so to purge the air from the pump it is
only necessary to open some tap for a few minutes.
