13.1. SELECTION OF PUMPS
NB:
For each NS model the selection of
the pump is unique, which means that
for all the circuits that make up the
selected model the pump will always
be the same.
In the presence of a second reserve
pump, the switching is done manually
by acting on the pump switch located
inside the electrical panel.
Premise: the item's latest figure of the
selected model indicates the number
of hydraulic machinery and composes
the machinery. For the models 3002 to
4802, as said above the pump will be
selected by dividing the total water
flow rate indicated in the table of
technical data for 2 (last digit symbol of
trade). The same procedure should be
applied with the models 5002 to 7203.
As above mentioned the total flow is
divided into three (last digit of the sym-
bol). For all the remaining models, the
water flow rate remains the same as
indicated in the technical data table.
