INTEGRATION WARNINGS
CAUTION
Based on expertise, the selection and installation of components outside the unit is the responsibility of
the installer, who must work in accordance with good engineering practice and the regulations in force in
the country of destination.
CAUTION
The connecting pipes to the machinery must be adequately dimensioned for the actual water flow required
by the system when in operation. The water flow at the heat exchanger must always be constant. In
particular, pressure loss values must be subjected to the correction factors specified under 0 for the glycol
content present.
CAUTION
Clean the unit thoroughly before connecting it. This cleaning allows any possible residues, such as
welding beads, secretions, rust or other impurities, to be removed from the pipes. These substances
may otherwise accumulate inside the unit and lead to the unit malfunctioning.
CAUTION
The connecting lines must be adequately supported so that their weight does not burden the unit.
CAUTION
In the event of system downtime, the water contained in the heat exchanger may freeze and cause
irreparable damage to the source-side heat exchanger (AWN circuit). To avoid the danger of freezing,
there are three possible solutions:
1. Fully draining the water
from the unit.
2. Operating with glycolised water
, with a glycol content selected according to the minimum external
temperature.
3. Using resistors.
In this case, the resistors must always be live whenever there is the possibility of
frost (machine in standby mode).
CAUTION
If the AWN fan fails (loss of power or fault), ensure that the heat pump also switches off. Otherwise the
system may be damaged. For this purpose, a release signal must be transmitted from the AWN to the
Connect WP via a potential-free contact (see below).
