ATTENTION

The choice and installation of
components outside the NRP unit
is the installer's responsibility, who
must operate according to the
code of practice and in compliance
with the Standard in force in the
country of destination.

ATTENTION

The hydraulic connection pipes to
the appliance must be suitably di-
mensioned for the effective water
flow rate requested by the system
when running. The water flow rate
to the heat exchanger must always
be constant.

ATTENTION

Wash the system thoroughly
before connecting the unit. This
cleaning operation will eliminate
any residues such as welding drips,
scale, rust, or other impurities
from the piping. These substances
can also deposit inside and cause
appliance malfunctioning. The con-
nection piping must be adequately
supported so that its weight is not
borne by the appliance.

ATTENTION
SYSTEM DRAINING

If the system should stop during
the winter period, the water
present in the exchanger may
freeze, causing irreparable damage
to the exchanger itself.
There are three solutions possible
for the prevention of freezing:

1. Drain the water from the ap-

pliance

completely.

2. Operation with glycoled wa-

ter

, with a percentage of glycol

selected on the basis of the
minimum external tempera-
ture envisioned.

3. Use of resistances.

In this case, the resistances
must be live for the entire
period that freezing may occur
(machine in stand-by).
