3. GENERAL INSTRUCTIONS
A hazard analysis of the product has been carried out as provided in the Machine Directive. This ma-
nual contains information for all personnel exposed to these hazards, with the aim of preventing pos-
sible harm or damage due to faulty handling or maintenance.
All maintenance operations (ordinary and extraordinary) must be carried out with the machine swit-
ched 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 corres-
ponds 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 40 and 54 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 and 33
These models are designed to be installed hanging from the ceiling or located behind a false ceiling.
The 04, 08, 12, 16, 21 and 33 models have four metal brackets, one on each lower corner. 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 connections and the
pipelines.

Vertical models
The models size 4 to 21 are supplied with support feet, while the models size 40 and 54 are supplied
with a perimetral bed. This bed must be in contact with the ground or with a fl at surface. It is essential
that the weight of the equipment is distributed between all points of support to prevent unit deforma-
tion.
The installer must make sure that the ceiling structure and the securing elements can bear the
weight of the unit, taking into account that it is a dynamic load.

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 install
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 duct,
connection to the electric supply, and in the case of versions with water coil, the connection with closed
circuit of hot water coil.
Inside of the unit are supplied the following accessories:

In these versions, the drainpipe and the siphon are supplied mounted in the unit.
6.1.1. Outdoor installation
The CADB/T-HE PRO-REG range is designed to be mounted indoors. When it is installed
outdoors, it is necessary to place the equipment under a cover which offers enough protection
to prevent rain falling directly to the unit, or install the corresponding roof mounting.
In horizontal version, models 04 to 33, ensure the sufficient space below the unit, to install a
siphons in the drain pipe.

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 pre-
vent condensation formation on cabinet surfaces and electronic components.

6.5.1. Piping and duct connections
6.5.1.1. Connection with air duct
The fans are always blowing out with regard to the machine. Before making the connection of air
lines, verify existing identification labels in each mouth of the heat recovery units.

6.5.1.2. Connecting the water coil piping. DC Versions
Connecting the unit to the water network
- Maximum pressure: 10 bar
- Maximum temperature: 100°C
• Minimum temperature: -20ºC (with the addition of
the corresponding antifreeze).
• Water coils of DC versions have threaded connec-
tions. Secure the coil manifold with the appropiate
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, 16, 21 and 33 1/2”
40 and 54 1”
• To ensure the installation on a hand, it is essential that the installation includes the following
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.

6.5.1.3. Condensate drainage
The units are supplied with 2 drains (one for each circuit). For added security it has to connect
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
6.5.2. Electrical connection
In the recovery unit PRO-REG range, all components integrated into the device, are supplied into
the electrical panel (motors, pressure filters, motor pressure switches, temperature sensors,
batteries and by-pass damper).
The electrical connection is limited to the connection of control terminal (10 m. of supplied ca-
ble) and possible electrical accessories as such as CO2sensors or control valves for water coils,
and finally the connection of the power supply line.
Make electrical connection in accordance with the described in the corresponding wiring dia-
gram, found at the end of this manual.
6.5.2.1. External Touch Display (ETD) control connection
The ETD control must be connected to the controller with a 4 wires shielded twisted-wire pair
cable of 100 m max length. 4P4C connector is reserved for ETD.

17
ENGLISH
The ETD control has an electrical protection IP-20 degree, so it is valid; it is reserved exclusively
for an indoor usage sheltered from moisture.
It is equipped with an internal temperature probe.
In case of an outdoor mounting of the CADB/T-HE unit OI, you can also leave it inside the hou-
sing of the electrical box. Once the parameter setting is done, the remote control can be dis-
connected.
Placement of the support and the remote control:

6.6. CONFIGURATIONS
CADB/T-HE D/DI/DC PRO-REG standard configuration
From these configurations there are multiple variables that can be performed by the professional
installer quickly and easily.
Panel replacement process
The CADB-HE heat recovery units are available in two configurations LH and RH in the horizontal mo-
dels and LV, RV in vertical models.
