3. Product Description
A. General Information
This User’s Guide is intended to provide the necessar information for the use of
TOTEM units. TOTEM micro cogeneration units are appliances that allow for the
combined production of electricit and heat at the user’s site, thus optimizing the use
of the fuel’s primar energ and reducing grid distribution and separate generation
losses.
CHP units, indeed, can be easil integrated into an technological environment,
enabling fulfillment of the heating requirements of different users in a variet of
sectors:
hospitalit ;
wellbeing;
catering;
health-care;
housing;
public;
agri-food;
distribution chains.
Using a micro cogeneration unit allows to achieve significant economic savings and
environmental benefits.
The unit consists of an endothermic engine originall devised for the automotive
industr , coupled to an as nchronous generator.
The heat produced in the endothermic engine’s combustion process is almost full
recovered b means of a high-efficienc heat exchangers s stem and made available
to users as hot water.
Thanks to its modern propellers manufactured b FCA, speciall engineered to run on
gas and optimized to work under stead -state, the unit allows for optimized
performance and longer maintenance intervals. Moreover, its modern Euro 6
technolog enables a significant reduction of nitrogen oxides - NO
x
- and carbon
monoxide - CO - emissions as compared to conventional condensing boilers.
TOTEM® units’ compact size and versatilit allows installation in tight equipment
rooms and their use on existing premises, including with environmental or
architectural constraints.
Its control s stems allow to monitor and log data for power and heating load profiles,
including remotel . Moreover, it enables service staff to monitor an alarm signal
detected thus enabling emergenc service in case of breakdown or malfunctioning.

exhaust duct. It is equipped with a lambda sensor for injected mass control as well
as with a sensor checking gas temperature right at the engine outlet.
The manifold is efficientl insulated so as to minimize heat dispersion along this
section. Gases then go through the coaxial heat exchanger where a first cooling
stage takes place, after which the are sent to the three-wa catal st where
emissions are lowered. The ceramic substrate catal st simultaneousl reduces CO,
NO
x
and HC emissions. It is fitted with a sensor at the inlet to check the right
operating temperature for the catal st, plus a lambda sensor downstream for a
second level titration control. The catal st is thermall insulated, too. The gases
leaving the catal st reach the tube bundle exchanger where the are cooled down
until condensation occurs (T<70°C).
Before being discharged, gases go through an exhaust gas silencer, specificall
devised to lower the noise emissions from the micro-cogenerator for the given rev
number.
-Electrical and Control Switchboard
The Electrical Switchboard complies with current applicable standards and it contains
all the electrical safet devices as well as all control devices governing the unit’s

E. Safet Instructions
The TOTEM is equipped with EN ISO 13849 compliant safet s stems so as to
protect machine operators and maintenance staff against hazards linked to the
micro-cogenerator operation.
Risk anal sis has identified the following hazards:
Exhaust gas emissions
Lack of water flow
Spark advanced with temperature increase
Methane gas leak
The s stem is composed of a chain of safet sensors: an electromechanical
thermostat, a methane gas sensor, and an emergenc pushbutton.
Methane gas leakage hazard
The TOTEM is fitted with a catal thic methane gas sensor for gas leaks. The sensor
features a two-threshold calibration that trigger safet s stem activation when gas
leaks are detected inside the unit’s enclosure. The first threshold value is set to 20%
of LEL. Values exceeding threshold are sent to the ARYA PLC that will command the

unit to turn off thus restoring safet conditions. The second threshold value is set to
50% of LEL, exceeding of this values is reported directl to the safet rela that is
actuated even in the event of PLC malfunctioning, closing the gas suppl valve and
turning the unit off.The electrical switchboard terminal block includes a contact for
connection to the natural gas solenoid of the central heating s stem. In the event of
a gas leak, the rela opens this circuit, too, b commanding valve closure.
Exhaust Gas Emission Hazard, Lack of Water Flow Hazard, Timing variation
Hazard
The above mentioned occurrences can pose a danger b causing an increase in
temperature which ma cause some of the unit’s parts to become hot thus putting
the operator at risk of burns, or b causing a discharge of exhaust gases that
upstream of the catal st feature a high carbon monoxide content.
These anomalies can be detected b a safet thermostat fitted inside the unit’s
enclosure and calibrated to actuate the emergenc rela upon reaching 75°C, which
willl switch the unit off. This is a certified s stem guaranteeing high reliabilit even in
the event of a failure of all other control s stems fitted onto the TOTEM.
Emergency Pushbutton
The Operator Panel features an emergenc pushbutton that can be pressed in the
event of an risk situation. The emergenc pushbutton actuates the emergenc rela
that will switch the micro cogenerator off thus restoring safet .
In order to ensure proper functioning of the safet devices and, consequentl ,
Totem’s operation under full safe conditions, the following requirements must
mandatoril be met upon installation:
-The central heating s stem solenoid must be connected to the speciall
devised terminal block located on the TOTEM electrical switchboard;
-Proper room ventilation – at least 600 m
3
/h must be ensured or,
alternativel , enough windows must be provided in the room so as to
ensure an equivalent ventilation rate according to volumes, or a CO sensor
must be installed in the central heating s stem.

I. Noise Emissions and Vibrations
Thanks to its high-qualit technical solutions and its high-performing sound insulation
materials, the TOTEM® units feature low noise emissions.
The data shown in the technical datasheet are measured at 1 m distance, free-field,
as per standards.
Despite its carefull selected sound-insulating, vibration-damping materials, when in
operation the TOTEM® unit can generate small vibrations that ma in some cases be
transferred to surrounding structures.
For extremel sound sensitive applications, additional solutions ma be necessar to
further reduce noise and vibrations.
4. Use of the Micro Cogenerator
A. Preparing the Unit for Use
Before starting the unit, ensure that all connections described in the Installation
Guide have been performed correctl .
All installation procedures must be performed solel b Qualified Technicians.
A description of said procedures is provided in the Installation Guide.
In all cases, commissioning must be performed solel b authorized Totem Energ
personnel b calling the Technical Support Service. Carr ing out commissioning
without the supervision of Totem Energ authorized personnel will nullif the
warrant .
In the event that the unit has to be restarted after prolonged inactivit , we
recommend calling the Technical Support Service.
Once all connections to the User s stems have been checked, it is possible to
operate the Main Switch thus powering the Electrical Board and switching the
Touchscreen Operator Panel on. the Panel’s displa will become operational after a
few minutes.
TOTEM units use air for combustion. The proper amount of air for recirculation in the
room - 600 m
3
/hour - must also be provided through suitabl sized openings in the
building envelope. Such airflow inlets must not interfere with pre-existing openings, if
an , created for other devices or heat generators.
To ensure the unit’s proper functioning, the ambient operating temperature must
range between 1°C and 40°C.
For applications with ambient temperatures that ma , even occasionall , be equal to
or lower than 0°C, it is mandator to treat the user s stem’s water properl and add
an anti-freeze solution in suitable concentration.
For applications in areas with ambient temperatures that ma , even occasionall , get
lower than -15°C, it is mandator to properl treat the micro cogenerator’s internal
circuit coolant, too. Please contact TOTEM ENERGY’s Technical Support Service.
