4 INSTALLATION REQUIREMENTS

WARNING: the unit installation and start-up must be entrusted to competent personnel and performed in a workmanlike manner, in accordance with current regulations.
WARNING: It is advisable to install any accessories on the standard equipment, before positioning it, referring to the technical sheets.
WARNING: Thermal ventilating and conditioning FWN unit may be installed horizontal as in vertical configuration. Make sure that the desired configuration is corrected and matches with one of the figure 7 p.55. Configuration AA and AB are both suitable for heating and cooling operation.
WARNING: The units are always supplied in AA configuration, but the air intake position may be changed during the installation. If the installation differs from the supply terms, the layout must be changed by dismantling the unit. (See figure 1 p.49)

Warning for ducted units:

The unit must be installed on the basis of design and technical considerations, carrying out an aeraulic assessment and considering the BACK PRESSURE offered by the PILING applied to the outlet to avoid the problem of failure to change speed: this responsibility cannot fall on the product but on the installation;

Install the unit with the appropriate inspection hatches for routine and special maintenance of the fan coils: for mechanical, electrical and hydraulic replacement;

WARNING: First installation ensure that:

5 INSTALLATION

The sections of the intake and delivery pipes are rectangular, drilled with holes for fixing the available accessories. A round pre-sheared element ( 100mm) is present on both side panels of the unit for the direct inlet of the external air.

To implement the rectangular-section channel-type connection use accessory PRD, which may be fit either at intake or at delivery. 2 PRD accessory panels are required for implementing the intake and delivery with channels. See figure 5 p. 54.
To implement the flexible tube-type connection, use accessory PCIC, which is fitted directly on the machine's intake inlets, by means of drilling. 2 PCIC accessory panels are required for implementing the intake and delivery with flexible tubes. See figure 6 p.54.

1. The place of installation has sufficient space for containing the device and for performing installation and maintenance. See figure 2-3 p.50 and p.52.
2. The air inlet and delivery are not obstructed.
3. The hydraulic connections are positioned and dimensioned as requested by the device. See figure 2-3 from p.50 and p.52.
4. The electric power supply line has the features requested on the fan coil's data plate.

WARNING: Install the unit, circuit breaker (IL) and/or any remote controls in a place out of reach of persons who may be taking a bath or shower.

The exchanger connections can be switched over to the opposite side, is recommended to do this before installation, by carrying out the following steps (figure 12 p.57):

remove the upper and lower closing panels.
remove the condensate tank for the horizontal installation.
loosen the 4 fixing screws of the motor support, without unscrewing them all the way.
remove the heat exchanger by unscrewing the 4 fastening screws.

turn the heat exchanger by 180^ (vertical axis), eliminate the presheared elements on the opposite side panel, reinsert the heat exchanger on the unit.
reassemble the previously listed components.
stop the outlet holes of the previously used manifolds with anticon-densing insulating material.

Some rules to follow:

—Vent air from the exchanger while the pumps are off. For this purpose use the air vent valves situated next to the exchanger connections.
- When implementing a channel-type system, it is advisable to place the vibrationdamping joints (available as accessory GA) between the channeling and the unit.
If you wish to install an electrical resistance module (KER) as accessory, the delivery vibration-damping joint should be heat-resistant (accessory GA-T).
All ducts, especially the outlet ducts, must be insulated with anti-condensation material.

An inspection panel must be provided in proximity to the unit to enable maintenance and cleaning operations.

Install the control panel on the wall; choose an accessible position from where functions may be easily set and which is suitable for taking temperature readings, where applicable. Avoid positions directly exposed to sunlight or direct currents of hot or cold air and make sure there are no obstacles which may preclude a correct temperature reading.

WARNING:

In normal operation, particularly with the fan at minimum speed and ambient air with high relative humidity, condensation may form on the air outlet and on some external parts of the unit.

To avoid such issues while always remaining within the operating limits envisaged for the unit, it is necessary to limit the inlet temperature of the water inside the heat exchanger. In particular, the difference between the air dew point (TA,DP) and the inlet water temperature (Tw) must NOT exceed 14^ , according to the following relationship: TW>TA,DP-14°C

Example: in the case of ambient air at 25^ with 75% relative humidity, the dew point temperature is about 20^ and therefore the inlet temperature of the water in the battery must be greater then:

• 20 - 14 = 6^ in order to avoid condensation on a fanoil equipped with a valve.

20-12 = 8 °C If the valve kit accessory can not be installed.

In the event the indoor unit is stopped for a prolonged period, with the fan stopped and circulation of cold water in the heat exchanger, condensation may also form on the unit's exterior. In this case it is advisable to install the 3-way (or 2-way) valve accessory in order to stop the flow of water in the coil when the fan is stopped.

During wintertime periods of quiescence, drain water from the system, to prevent ice from forming. If anti-freeze solutions are used, check for their freezing point using the table below.

% Glycol by weight	Freezing temperature (℃)	Capacity adjustment	Pressure drop adjustment
0.01,001,00
10	-4	0.971,05
20	-10	0.921,10
30	-16	0.871,15
40	-24	0.821,20

5.1 ASSEMBLY OF UNITS

Fix the standard unit to the ceiling or wall using at least 4 of the 6 slots; For horizontal installations (ceiling-mounting) it is advisable to use 8MA threaded bars, screw anchors suitable for the machine's weight, and to arrange for the positioning of the machine using 2

8MA bolts and a washer the diameter of which is suitable for inserting the slot and for then fixing the unit.

Before tightening the check nut, adjust the closing of the main nut so that the equipment will slant correctly, i.e. for facilitating the discharging of the condensate.
In case of wall installation, to favour the drainage of condensate, the drain hose should be inclined downward, at least 3 / 5mm provide for the correct drainage of the condensate drain pipe according to need. The two condensate discharge tubes of the main tank are located inside the side panels and may be accessed through a membrane type raceway that should be etched for passing the discharge tube through it. It is advisable not to remove the aforesaid raceway because it prevents the sharp edge of the hole on the side panel from damaging the condensate discharge tube over time.
In case of ceiling installation, in particular when the EDDPH accessory is present, install the unit with a slight slope (10 mm), in order to facilitate the condensate drainage. (See figure 10 p. 56). The condensate discharge could be on left side or right side, at the choice of the installer. Slope towards the chosen side, then close the unused side with the cap and place the pipette on the side of the chosen drain, see dimensional drawings p. 50 and p. 52.
Make the plumbing connections to the heat exchanger and, where the cooling function is to be used, to the condensate drainage outlet.
- To connect the unit to the drainage line, use a flexible rubber hose and secure it to the pre-selected drain pipe (Ø 3/8") using a metal clamp (use the drain outlet situated on the plumbing connection side).
To assist the draining of the condensate, slant the discharge tube downwardsby at least 30mm / m making sure that its entire route is clear and free from bends or blockages.

The 3 way valve kit includes hydronic kit, drain pan and valve body insulating shell
(1) for sizes 12 + 18 , only the valves and the corresponding servomotor are supplied. For these series it is preferable to install units and valves together with the associated servomotors, not at the back of the units, but in a position adjacent to the main hydraulic circuit.
(^*) For sizes 12 + 18 the drain pan is not included in the kit. Always insulate the valve to avoid condensate formed on the valves
