10. HYDRAULIC CIRCUIT
10.1.
ATTENTION
The choice and the installation
of components external to
the NRL up to the installer,
who must operate according
to the rules of good technical
design and in compliance with
the regulations in force in the
country of destination.
ATTENTION
The hydraulic pipes connecting
to the machine must be pro-
perly sized to the actual flow of
water required by the system
in operation. The water flow to
the exchanger must always be
constant.
ATTENTION
Carefully wash the plant, be-
fore connecting the unit. This
allows cleaning to remove any
residue such as weld spatter,
slag, rust or other impurities
from the pipes. These substan-
ces may otherwise accumulate
in and cause a machine mal-
function. The connecting pipes
should be supported so as not
to weigh, with their weight on
the unit.
