The unit must be installed according to national and local standards that regulate the use of electrical devices and according to the following
indications:
•install the unit inside residential buildings with an ambient temperature between 3 ° C and 45 ° C;
•avoid areas near sources of heat, steam, flammable and / or explosive gases and particularly dusty areas;
•install the unit in a place not subject to frost (the condensation water must be drained not frozen, at a certain inclination, using a
siphon;
•do not install the unit in areas with a high relative humidity rate (such as a bathroom or toilet) to avoid condensation on the
external surface;
•choose an installation site where there is sufficient space around the unit for the connections of the air ducts and to be able to
carry out maintenance operations;
•the consistency of the ceiling / wall / floor where the unit will be installed must be adequate for the weight of the unit and not
cause vibrations.
The environment chosen for the installation must contain:
•connections of the air ducts;
•230 V single-phase electrical connection
•connection for condensate drain
•water inlet and outlet water connection
2.2 UNIT POSITIONING
Ceiling mount
To mount the unit on the ceiling, you need:
•Use the 4 mounting holes on the top of the unit.
•Fix the unit to the ceiling, using the brackets, using
suitable anchoring systems (dowels, threaded bars,
chains…) and check the leveling with the help of a
level.

2.3 CONDENSATE DRAIN CONNECTION
For the heat recovery unit to function correctly, a condensate drain must be connected to the plumbing system (drain) of the house.
Furthermore, to allow the condensate water to flow correctly and avoid unpleasant odors, the condensate drain must always be equipped
with the appropriate siphon to be placed on the drain line by the installer;
To install the condensate drain, comply with the following
standards:
•give a slope of at least 2% to the exhaust pipe;
•provide for the possibility of disconnecting the drain
hose for any maintenance (in particular in the case of
ceiling installation);
•make sure that the discharge end of the pipe is at
least below the water level of the siphon;
•make sure that the siphon is always full of water.
In horizontal positioning the drain is 18 mm in diameter;

4HYDRAULIC CONNECTIONS
4.1 GENERALITY
The units are equipped with hydronic coils with water-air exchange;
-The connections on the units, even in the different applications and versions, are always common to all the units.
-Make sure to respect the flows indicated on the labels: inlet (water entering the unit), outlet (water leaving the unit)
- Make sure that the weight of the pipes does not weigh on the predisposed connections
-Provide shut-off valves on the delivery and return pipes to the system
-All the chilled water pipes must be insulated to minimize unwanted heat exchanges and the formation of condensation.
- Before filling the pipes, make sure that they do not contain foreign materials: such as sand, stones, rust flakes, welding drops, slag, etc.
Otherwise, wash the hydraulic circuit by bypassing the unit.
- Absolutely avoid pump cavitation and the consequent presence of air in the hydraulic circuit.
Physico-chemical characteristics of water
Incompatible chemical-physical characteristics could compromise the integrity of the hydraulic parts of the unit.
Check the characteristics of the water:

4.2 POSITIONING AND CONNECTION PROCEDURES
The hydraulic connections are located on the side of the
unit.
The connections are with Eurokonus ¾ ”male thread.
Respect IN as the water inlet to the
unit and OUT as the
water outlet from the unit.
Connect the pipes with a Eurokonus threaded fitting and
tighten it with dedicated tools;
The external thread is connected through a swivel fitting to
the battery to prevent rotation in the tightening
from
damaging the internal pipes;
In any case, be careful not to rotate or twist the pipes
coming from inside the unit;
Rotating the pipes during connection could damage the
connections inside the unit and cause water leaks during
operation;
