1 MAIN FEATURES

PERFORMANCE AND COMPACTNESS IN RECESSED CEILING INSTALLATIONS

The FWB-C ducted unit has been conceived for air condition-

ing interiors where the installation of high-performance medi-

um-head units with reduced overall dimensions is required. The

range features 8 models with air ows of from 300 to 1200 m3/h

with over 70Pa available static pressure and cooling powers

from 2 to 8 kW.

The heat exchanger enables FWB-C to be used under a whole

variety of operating conditions. The weight-bearing structure in

fact houses a 3- or 4-rows exchanger which can be combined

with an additional 1- or 2-rows exchanger for exceptional perfor-

mance even with low temperature dierentials.

Heat exchanger can be optimized for centralized applications

such as district cooling. FWB-C was designed to ceiling horizon-

tal installation.

The main condensate drip tray is situated inside the structure of

the unit and is at a positive pressure relative to the drain outlet

to facilitate condensate drainage.

A wide range of wall-mounted controllers is available, includ-

ing microprocessor controllers with display. Heating elements

complete with safety devices are available to supplement the

hydronic system.

2 MAIN COMPONENTS

STRUCTURE

Built from galvanised steel sheet, heat and sound insulated by

means of Class 1 self-extinguishing panels. Reduced height to

facilitate installation in a horizontal position in a false ceiling. The

structure incorporates a drip tray and condensate drain outlet.

The bearing structure allows to combine a large range of acces-

sories in suction and air delivery in order to obtain the optimized

unit conguration.

ELECTRIC MOTOR

Single-phase asynchronous multi-speed electric motor with permanently connected capacitor and thermal protector, mounted on

vibration-damping supports.

AIR FILTER

Washable air lter, made of acrylic bre, ltration class G3, applied on the air intake; may be pulled out from below.

AIR INTAKE

Air intake from the front or bottom of the unit, according to system requirements.

HEAT EXCHANGER

High eciency standard with 3 rows, but also available with 4

rows upon request, heat exchanger made with copper piping

and aluminium ns blocked to pipings by mechanical expan-

sion, provided with brass manifolds and air vent valve.The heat

exchanger usually comes with water connections mounted on

the left, but it can be turned by 180°. High-eciency heat ex-

changers optimized for district cooling applications are availa-

ble on request.

FANS

Double suction centrifugal fans made with ABS or aluminium, with statically and dynamically balanced forward-curving blades,

directly coupled to the electric motor.

3 INSTALLATION

WARNING: unit installation and start-up must be entrusted

to competent personnel and performed in a workmanlike

manner, in accordance with current regulations.

WARNING: Install the ducted unit, the line switch (IL) and/or

all remote controls in a position out of the reach of persons

who are in the bathroom or in the shower.

DANGER: The unit may be used by children of at least 8

years of age and by persons with reduced physical, sen-

sory, or mental capabilities, or who lack experience or the

necessary knowledge, provided that they are supervised or

after they have received instructions relating to the safe use

of the unit and understand the inherent dangers. Children

must not play with the unit. Cleaning and maintenance to

be carried out by the user must not be performed by unsu-

pervised children.

IMPORTANT: It is advisable to install any accessories on the

standard unit prior to positioning the latter, making refer-

ence to the technical sheets. The air intake and outlet have

a rectangular cross-section, with pre-cut holes for fastening

the available accessories.

The heat exchanger connections can be switched over to the op-

posite side by carrying out the following steps:

 remove the upper closing panel.

 remove the collecting condensate tray.

 remove the heat exchanger module by taking out the fas-

tening screws (2 per side).

 turn the heat exchanger by 180° (on the vertical axis) and

screw it back into the unit again.

 reassemble the tray and the upper closing panel.

3.1 INSTALLATION REQUIREMENTS

Some rules to follow

 Vent air from the exchanger while the pumps are o. For

this purpose use the air vent valves situated next to the ex-

changer connections.

 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 cur-

rents 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, conden-

sation may form on the air outlet and on some external parts

of the unit.

To avoid such issues while always remaining within the oper-

ating limits envisaged for the unit, it is necessary to limit the

inlet temperature of the water inside the heat exchanger. In

particular, the dierence between the air dew point (TA,DP)

and the inlet water temperature (TW) must NOT exceed 14

°C, according to the following relationship: TW>TA,DP-14

°C

Example: in the case of ambient air at 25 ° C with 75% rela-

tive humidity, the dew point temperature is about 20 ° C and

therefore the inlet temperature of the water in the battery

must be greater then:

 20-14 = 6 °C in order to avoid condensation on a fancoil

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 peri-

od, 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 ow of water in

the coil when the fan is stopped.

During wintertime periods of shut down, 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.

3.2 TROUBLESHOOTING

If the unit is not working properly, before calling a service engi-

neer carry out the checks indicated in the table below.

If the problem cannot be solved, contact your dealer or the near-

est service centre.

3.3 ASSEMBLY OF UNITS

Mounting the unit

Insert the vibration dampers provided in the 4 slots indicated for

ceiling installation

Fasten the base unit to the ceiling or wall using at least 4 of the

8 slots provided.

 It is recommended to use 8MA threaded bars plus screw an-

chors of adequate capacity to bear the weight of the unit,

and to prepare the positioning of the unit using 3 8MA bolts

(2 in the lower part, 1 in the upper part as shown in g-

ure p.6) and two washers for each bar. Before tightening

the lock nut, adjust the main nut so as to assure that the unit

is properly inclined so as to facilitate condensate drainage

(gure p.6). To obtain the proper inclination, tilt the unit

so that the intake side is slightly lower (approximately 10

mm) than the outlet side. Make the plumbing connections

to the heat exchanger and, where the cooling function is to

be used, to the condensate drainage outlet. Use one of the

two tray drain outlets, which can be seen on the outside of

the unit side panels.

 To connect the unit to the drainage line, use a exible rub-

ber 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).
