of the device.
■It is mandatory to follow the instructions in this manual, particularly concerning safety rules.
■In no case will Systema be responsible for any direct or indirect damage to humans, animals, or property, resulting from
user’s failure to follow the instructions given in this manual.
■This Operation Manual is an important and integral part of the device and should be stored carefully the installation for
further reference.
■Please, carefully read the instructions and warnings contained in this manual before installation and use of the device, as
they provide important information regarding safety, installation, operation, and maintenance.
■If the manual is lost, please contact the manufacturer immediately.
■In case of change of owner or new tenant, please provide all the documentation related to the heating device to the new
owner/tenant.
■When transferring the product to a new user please check the integrity and completeness of the device and its compo-
nents. If the device and/or its components do not comply with the requirements, contact the seller.
■When installation work is complete, the installer should provide the owner with the necessary documentation to certify
that installation has been carried out in a workmanlike manner and complies with the applicable country regulations.
■Excessively high temperatures in a heated space may be harmful to health and are a waste of energy. We recommend
using your device reasonably.
■The manufacturer is responsible for the compliance of its product with the applicable rules at the time of the product
selling.
■Compliance with the current legislation and regulations for the design of the systems, its installation, operation, and
maintenance are the sole responsibility of the designer, installer and user.
■Distribution of this product without prior notice to the manufacturer is prohibited. In the country where the device was
nally installed specic documentation is required, depending on the country of destination of the product.
■Additional devices installed in the same room or directly communicating rooms are considered as a single system, with
a heat output equal to the sum of the thermal ows of the individual devices.
WARNING
■To ensure proper behavior of devices, it is important to strictly follow the manufacturer's instructions, to use original ac-
cessories and spare parts and to have the system maintained by qualied personnel (at least once a year).
■Do not install devices in areas, intended for trade or industrial activities, where the storage of materials and processing
thereof pose the risk of gas, vapor or dust generation, which can cause res or explosions.
■It should be possible to exchange air regularly in sites where the devices are installed, according to the current regula-
tions.
■Installation, routing of gas pipes, electrical connection, the initial startup, and maintenance should be carried out by qua-
lied personnel, following the instructions in this manual and should comply to the current national and local regulations
of the country where the system is installed.
■Gas supply and electrical connections should comply with the current national and local regulations of the country where
the system is installed. Where required, they should be designed by a qualied professional.
■The systems (gas pipes, power sources, etc.) should be designed without creating obstacles or risks to personnel.
■Do not use gas pipes for grounding of electric devices.
■Before starting devices, please check:
– that the parameters of the electric power supply and gas supply networks are compatible with the instructions given in
this manual and on the devices’ nameplates;
– that tightness of the gas supply system complies with the applicable standards and dimensions, and is equipped with
all the necessary safety and control devices required by current regulations;
– the proper routing and operation of gas exhaust and air intake pipelines;
– the correct realization and operation of the delivery conduit of the condensate drain.
■This device should be used for its intended purpose only. Any other use is considered improper and therefore dangerous.
■In no case will the manufacturer be subjected to civil or criminal liability for any damage to humans or animals due to
incorrect installation, adjustment and maintenance, modications and tampering, use of non-original spare parts and
accessories, incorrect and/or improper use of the device, noncompliance with the manufacturer’s instructions and inter-
vention of unqualied personnel.
■If the device is not used for long periods, it is recommended to perform the following operations:
– turn the device main power switch and system master switch to OFF;
– close the main shut-o󰀨 gas valve.
■After long periods when the device was not used we recommend to contact the technical support or qualied technical
personnel to put the device back into operation.
■If the device is stopped and/or malfunctioning, please turn it o󰀨. Any repair or replacement of components should be

GENERAL RULES
carried out only by qualied personnel using only original spare parts. Failure to follow these rules may compromise the
safety of the device.
■Do not leave packaging elements (nylon, polystyrene foam, wood, staples, etc.) within the reach of children and/or unat-
tended, as they can be potential sources of danger and pollution. Collect and keep them in a special place.
Keep in mind that the use of electricity and gas-operated products must comply with some basic rules:
■The product shouldn't be used by disabled persons without assistance and children.
■If there is a smell of gas, do not operate electrical devices (such as switches), electrical appliances, etc. In such cases
proceed as follows:
– open the doors and windows to ensure air change in the premises;
– close the main shut-o󰀨 gas valve.
– in case of a breakdown do not try to manage it by yourself, but immediately call qualied personnel or technical support.
■Do not touch the device barefoot and with wet or moist parts of the body.
■Do not attempt to clean or service the device when it is connected to the electric power supply. To carry out these opera-
tions it is rst necessary to set the system master switch to OFF and close the supply of the fuel gas.
■It is strictly prohibited to tamper with or modify the safety and control systems without authorization and specic in-
structions from the device manufacturer.
■Do not pull, detach or twist the device’s electrical cables, even when they are disconnected from a power source.
■Do not open the device while it is in operation, rst set the main power switch to OFF.
■Do not place objects on top of the device, or insert them in exhaust and combustion air intake pipes.
■Do not touch the combustion chamber, exhaust pipe or other hot parts during the device operation, as hot surfaces can
cause burns. These surfaces may remain hot even after the device is turned o󰀨. Turn o󰀨 the system in case of activities
conducted near the equipment and continuously monitor the control panel to prevent it from being turned on.
■Do not tamper with the device control system at the control panel during maintenance. During maintenance, the service
technician must place a warning sign on the system control panel with the following message: “The device is under main-
tenance. DO NOT operate the device control panel!”.
■Do not use the xing system to support the weight of other devices or equipment. Specications for the xing system in
this manual take into account only the weight of one device with the exhaust and air intake pipes.
■Do not use the device as a support base and/or walkable surface.
■Do not block/cover the blower intake or air supply inlet.
Note
To switch o󰀨 the device, always use the room thermostat, not the main switch on the ground
control panel. The reason is that overheating of the combustion chamber can occur with sub-
sequent damage to the device itself.
1.1 EXPLOITATION
The condensing gas unit EOLO LX series are heat generators designed to be used as a module for
heating inside the air handling units and roof-tops.
The power is regulated automatically, modulating the heat input from minimum to maximum.
Thanks to the use of a premixed burner, specially designed for this specic application, high combustion e󰀩-
ciency is obtained.
In order to function, the unit must be connected to a gas supply system, to the electricity network, as well as
to a ue gas discharge pipe and a condensate drain pipe.
Note
Insert the EOLO LX series gas units in a system with an adequate air ow rate (see the nomi-
nal air ow rate indicated in tables 2.1 and 2.2)
