EFORE INSTALLATION
Installation and maintenance should be carried out by technical
personnel qualified for this type of machine, in compliance with
current safety regulations.
When receiving the unit please check its state, verifying if any
damage occurred during transport.
Refer to the relevant technical sheets for installation and use of
possible accessories.
Identify model and version of the unit from the indications stated on
the carton package.
U
SE AND OPERATING LIMITS
Daikin shall not be held liable
- if the unit has been installed by non-qualified personnel,
- if the unit has been used improperly,
- if the unit has been used under conditions that are not permitted,
- if maintenance operations specified in this manual have not been
carried out,
- if non original spare parts have been used.
Keep the unit in its packaging until it is ready to be installed, to
prevent dust getting inside.
Air sucked by the unit must always be filtered. Always use the
supplied air filter.
If the unit is not used during winter, drain the water from the system
to prevent damage caused by the formation of ice. If antifreeze
solutions are used, check the freezing point.
Do not change the internal wiring or other parts of the unit.
Operating limits are shown here below; all other uses are considered
improper:
■ thermal carrier: water/glycol
■ water temperature: 5°C~95°C
■ maximum operating pressure: 10 bar
■ air temperature: –20°C~40°C
■ voltage tolerance: ±10%
Selection of location:
■ do not install the unit in rooms where inflammable gases are
present
■ do not let water spray directly on the unit;
■ install the unit on ceilings that bear its weight. Leave enough
space all around for proper operation and maintenance of the
unit, taking into account all installed optional accessories.
■ never place the heating unit immediately under an electric plug-
socket.
D ESCRIPTION OF THE EQUIPMENT
The FWB range of air conditioning and hot-air heating units has been
implemented for conditioning rooms that require the installation of
ducted units.
Main components
■ Load bearing structure made of galvanized steel sheet of
suitable thickness, duly insulated with noise-proof/anti-
condensing material, self-extinguishing in class 1. The unit is
equipped with 4 anti-vibration isolators.
■ Fan unit with single, dual or triple fan wheel, dual intake
centrifugal type, with statically and dynamically balanced
impellers, coupled directly to the 7-speed electric motor,
equipped with permanently fit condenser and thermal safety
device
■ Switch box located at the side of the hydraulic connections in
order to reduce the service space. Electric connection by means
of screw terminal strip .
■ High efficiency 3, 4 or 6 row heat exchanger , made of copper
tube and aluminium fins secured to the tubes by mechanical
expansion. They are fit with brass manifolds and contain air
valves. The heat exchanger, normally supplied with left-hand
attachments, may be turned 180°.
■ System for collecting and discharging condensate ,
extending beyond the hydraulic connections, enabling collection
of condensate from regulating valves eventually. The off-centre
position considerably reduces the required installation space.
■ Air filter made of acrylic material, self-extinguishing in class 1,
with filtering class EU 2. The removable cassette-type filter is
positioned on the air suction inlet and can be pulled out from
below like a drawer.
■ Straight duct connectors on both the air intake and air outlet.
D
IMENSIONS
■ Standard unit (See figure 1)
■ Air filter (See figure 2)

INSTALLATION
Exploded view of the unit (See figure 3)
Configuration of the unit
The heat exchanger connections can be switched over to the
opposite side by carrying out the following procedure. (See figure 4)
Installing the unit
Insert the supplied anti-vibration isolators in the 4 slots indicated for
ceiling installation. Fix the standard unit to the ceiling or wall using at
least 4 of the 8 slots;
■For installation it is advised to use M8 threaded bars, screw
anchors suitable for the unit's weight and to arrange for the
positioning of the unit using 3 M8 bolts (2 in the lower part, and 1
in the upper part as shown in figure 5) and 2 washers the
diameter of which is suitable for inserting the slot and for then
fixing the unit.
Before tightening the lock nut, adjust the closing of the main nut
so that the unit will slant correctly, i.e. for facilitating the
discharging of the condensate (see figure 6).
The correct slant is achieved by tilting the inlet downwards as
compared to the outlet until a difference in level of about 10 mm
is obtained from one end to the other. Make the hydraulic
connections with the heat exchanger and, for cooling operations,
with the condensate discharge. Use one of the 2 drains of the
drip tray, visible on the outside of the unit's side panels.
■To connect the unit to the condensate discharge line, use a
flexible rubber tube and fix it to the chosen discharge tube (Ø3/8")
by means of a metal clamp (use the discharge that is located on the
hydraulic attachments side).
To assist the draining of the condensate, slant the discharge
tube downwards by at least 30 mm/m making sure that its entire
route is clear and free from bendsor blockages.
A few rules to follow
■Purge the air from the heat exchanger, with pumps stopped,
by means of the air valves located adjacent to the
attachments of the heat exchanger itself.
■The ducting, especially the outlet duct, must be insulated
with anti-condensation material.
■Provide an inspection panel adjacent to the equipment for
the maintenance and cleaning operations.
■Install the control panel on the wall. Choose a position that is
easy to access for the setting of the functions and for
detecting of the temperature. Try to avoid positions that are
directly exposed to sun rays, or positions subject to direct hot
or cold air currents. Do not place obstacles in the way that
would prevent the correct reading of the temperature.
FIELD WIRING
Carry out the electrical wiring after having turned the power off. For
options, refer to the appropriate manual.
Check that the power supply corresponds to the nominal power
supply stated on the unit nameplate.
Each unit requires a switch (IL) on the power supply with a distance
of at least 3 mm between the opening contacts and a suitable safety
fuse (F).
Power consumption is shown on the data plate fixed to the unit.
Make sure to carefully execute the wiring in function of the
combination unit/controller and this according to the correct wiring
diagram delivered with every accessory.
In order to make the electrical connections you must remove the
panel covering the switch box (see figure 3) to access the terminal
strip.
The power cables (power supply and control) must be routed to the
terminal strip through the pwer supply cable intake holders on the
side of the switch box.
Wiring diagrams
The motors of the units run at 7 speeds.
The FWB air conditioning and hot-air heating units, the
circuit breaker (IL) and/or the remote control must be
installed out of reach of persons who may be taking a bath
or shower.

5Adjust the position of the drip tray so that the sticking-out part
extends below the hydraulic connections and fix it in place again.
6Screw the straight duct connector back to the heat exchanger
module.
All field wiring and components must be installed by a
licensed electrician and must comply with relevant local
and national regulations.

TEST RUN
Check that the equipment has been installed so that it guarantees the
required slant.
Check that the condensate discharge is not clogged (by rubble
deposits, etc.).
Check the seal of the hydraulic connections.
Check that the electrical wiring is perfectly tight (perform this check
with voltage OFF).
Be sure that the air purge of the heat exchanger has been carried out
correctly.
Turn on the power supply and check the unit running.
USE
To use the unit, refer to the instructions in the installation and
operation manual of the controller. Dedicated controllers are
available as accessory.
MAINTENANCE AND CLEANING
For safety reasons before carrying out any maintenance or cleaning
operation, turn off the unit and cut the voltage by turning the line
switch to OFF.
Maintenance
The maintenance operations for the FWB air conditioner and hot-air
heating units are limited to the periodic cleaning of the air filter and
the heat exchanger, and the checking of the working efficiency of the
condensate discharge.
Only skilled personnel may perform the maintenance.
Pay utmost attention during the maintenance operations: accidentally
coming into contact with some of the metallic parts might cause
injuries, therefore use safety work gloves.
Every time the units are started after a long idle period, make sure
that air is NOT present in the heat exchanger.
The motor is maintenance-free since it is equipped with self-
lubricating bearings.
Cleaning the air filter
Cut voltage to the unit by turning the line switch to OFF.
For cleaning the air filter proceed as follows:
■Access the equipment through the inspection panel and remove
the air filter as shown in figure 7 by unscrewing the fixing knobs.
■Wash the filter with lukewarm water or, for dry powders, with
compressed air.
■Reassemble the filter after having it dried up.
Cleaning the heat exchanger
It is advisable to check the condition of the heat exchanger before the
start of the summer season. Also check if the fins are not clogged by
impurities.
To access the heat exchanger, remove the delivery panel and the
condensate tank. Upon having accessed the heat exchanger, clean
with compressed air or low pressure steam, without damaging the
fins of the heat exchanger.
Before operating it in the summer, check the condensate discharges
regularly.
DISPOSAL REQUIREMENTS
Dismantling of the unit should be done in accordance with the
relevant local and national legislation.
