3. GENERAL INSTRUCTIONS
A hazard analysis of the product has been carried out as provided in the Machine Directive. This
manual contains information for all personnel exposed to these hazards, with the aim of preventing
possible harm or damage due to faulty handling or maintenance.
All maintenance operations (ordinary and extraordinary) must be carried out with the machine
switched off and the electrical power supply disconnected.
To avoid a possible accidental start up, place a warning notice on the electrical control panel with
the following text:
“Attention: control disconnected for maintenance operations”
Before connecting the power supply cable to the terminal strip, make sure the mains voltage co-
rresponds to the voltage indicated on the specifications plate of the unit.
Regularly check the product labels. If, due to the passing of time, they are no longer legible, they
must be replaced.
4. UNIT LABELLING
The machine may come with several pictograms that must not be removed. These signs are divided
into:
• Prohibition signs: Do not repair or adjust when in operation.
• Danger signs: Warning of the presence of live elements inside the container bearing the sign.
• Identification signs: CE card, indicating product information and manufacturer’s address. The
CE mark indicates the product’s conformity with EEC standards.

5. HANDLING
The CADB/T-HE models 04 to 33 are delivered fixed with screws to the pallets.
The models 45 to 100 are equipped with a bed, due to its weight are supplied without pallets. The
unit can be handled by a pallet transporter, a forklift, or a crane.
The handling machines will be adapted to the load and the lifting conditions. In all cases, the lifting
will be done at the device’s base. The centre of gravity is located at the centre of the unit. The device
must be carefully manipulated only in the horizontal position.

6. INSTALLATION
6.1. INTRODUCTION
Horizontal models size 04, 08, 12, 16, 21, 27 and 33
These models are designed to be installed hanging from the ceiling or located behind a false ceiling.
When installing the unit, is mandatory to distribute the unit weigh between all the supports existing
in the units:
• CADB-HE 04: 4 supports (one in each corner)
• CADB/T-HE 08 to 33: 6 supports (one in each corner and 2 centered in each side)
Using studded rods (Ø 8 mm), it can be secured to the ceiling and levelled.

The installer must make sure that the ceiling structure and the securing elements can bear the
weight of the device, taking into account that it is a dynamic load.
To prevent the transmission of vibrations from the unit to the rest of the installation, it is necessary
that the installer use specific isolation elements, such as antivibration devices in the supports,
flexible sleeves between the unit and the ducts, and flexible couplings between the water connec-
tions and the pipelines.

The models size 4 to 33 are supplied with support feet, while the models size 45 to 100 are supplied
with a perimetral bed. This bed must be in contact with the ground or with a fl at surface. It is es-
sential that the weight of the equipment is distributed between all points of support to prevent unit
deformation.

Particularities in the installation of horizontal versions LH and RH
For a correct evacuation of condensation generated into the heat exchanger, it is necessary to ins-
tall the unit with a minimum slope of 3º to the side where the extraction fan is placed:

For all configurations
Once secured the device in correct position, the installer have to realise the connection with air

with closed circuit of hot water coil.
Inside of the unit are supplied the following accessories:

d) Vertical versions of CADB/T HE 45, 60 and 100
In these versions, the drainpipe and the siphon are supplied mounted in the unit.
6.1.1. Outdoor installation
Whenever possible, it is advisable to be mounted indoors. When it is installed outdoors,it is
preferable to place the unit under a cover which offers enough protection to prevent rain falling
directly to the unit, or install the corresponding rain canopy (TPP accessory). Due to its design
and the position of its registers, it is preferable to use vertical versions (LV / RV) for outdoor
installation. In addition, these versions have feet that allow direct placement on the ground.
In horizontal version, models 04 to 33, ensure the sufficient space below the unit, to install
a siphons in the drain pipe. If installed on the ground, sufficient space must be guaranteed
under the unit so that it is possible to install the corresponding siphons in the condensate
outlets of the unit.

Connected to the condensate line
There is a Kit composed of 6 feet, which facilitates the assembly on floor of these versions:

2x Central supports
4x Corner supports
Detail of a CADB-HE 04 to 33 after the assembly of the KIT PIES CADB-HE

Both in the case that the Kit feet is used, and if the unit is based on vibrators or supports
made on site, it is essential that the heat exchanger’s support is guaranteed on the 6 existing
support points and that all of them are in a same plane.
In the case of not supporting the unit on the central supports it is possible that deformation
occurs in the structure of the unit, making it impossible to disassemble the panels.

Avoid condensations in electrical cabinet
In units located in outdoor installation where the heat recovery units stop during the night or
during long intervals of time, it is necessary to:
a) Install isolation dampers in air inlet and air outlet.
b) Add anticondensation devices in the electrical cabinet as: cabinet heating elements that
prevent condensation formation on cabinet surfaces and electronic components.

6.5.2. Connecting the water coil piping. DC Versions
Connecting the unit to the water network
- Maximum pressure: 31.62 bar
- Maximum temperature: 150°C
• Water coils of DC versions have threaded con-
nections. Secure the coil manifold with the ap-
propiate tool when tightening the threads. This
will prevent the force from being transmitted to
the manifold, which can damage it.
• The following table indicate the size and type o thread used on water coils for DC versions:
CADB/T-HE MODEL THREAD
04, 08, 12, 16, 21, 27 and 33 1/2”
45, 60 and 100 1”
• To ensure the installation on a hand, it is essential that the installation includes the fo-
llowing elements:
- Unit intake pre-filter that traps suspended particulate matter.
- Bleed valves should be fitted at each of the high points in the installation.
- Auto-filter valve to keep water in the hydraulic system at all times.
- Pressure to detect the lack of water pressure.
- Shut-off valves must be installed at each connection on the water line to allow the unit to
be isolated if necessary (to clean filters, make repairs, replace parts, etc) and avoid the
need to completely drain the water circuit.
- Anti-vibration bellows should be installed at the inlet and outlet from the unit to prevent
the transmission of vibrations that could result in damage to the heat exchanger coil due
to excess stress on the circuits.
Once the installation is performed check that the heating water flow is adequate.

16
6.5.3. Condensate drainage
The units are supplied with 2 drains (one for each circuit). For added security it has to con-
nect two drains to the condensate discharge pipe. This connection must be made through a
pipe of 22 mm of inner diameter and a flange for secure fixation.
Drainage system
• To ensure the removal of draining condensate from the tray a siphon must be installed with
pressure head difference in mmWG greater than the pressure provided by the fan.
• The horizontal sections should have a minimum slope of 2%.
Condensation connection
6.6. ELECTRICAL CONNECTIONS
The CADB/T-HE ECOWATT range are supplied without a complete operating control integrated in
the unit, however the units include the electronic to control fan speed. The electrical components
included in the unit are supplied wired in a terminal box or in a terminal board located inside the
unit (depending on the version).
6.6.1. Connecting the motors
Horizontal versions CADB/T-HE 04 to 27 LH/RH
In these sizes the units have plug-fans with EC motors 230V supply voltage.

CADB/T-HE 45, 60 and 100 models
The models of sizes 45 to 100 have three phase motors EC. Three-phase power EC. All ver-
sions include a cut-out switch to which the fan power is wired.
In the case of -DI versions equipped with resistances of post electric heating. The current
cut-out control of the resistances must be carried out by the electric installer.
6.6.2. Connecting the By-pass
All heat recovery units of the CADB/T-HE ECOWATT range have an internal by-pass. The
by-pass damper is supplied with its actuator mounted (Supply voltage 230V). The actuator is
wired to an external terminal box or to the electrical board (depending on the version).
With the FC-REG accessory is possible to control the by-pass in free-cooling mode.
