1. General instructions
• Carefully read the instructions contained in this instruction
booklet.
• After hot water tank installation, inform the user regarding
its operation and give him this manual, which is an integral
and essential part of the ECOUNIT F and must be kept with
care for future reference.
• Installation and maintenance must be carried out by profes-
sionallyqualiedpersonnel,accordingtocurrentregulations
and the manufacturer's instructions. Do not carry out any
operation on the sealed control parts.
• Incorrect installation or inadequate maintenance can result
in damage or injury. The Manufacturer declines any liability
for damage due to errors in installation and use or failure to
follow the instructions.
• Before carrying out any cleaning or maintenance operation,
disconnect the unit from the electrical power supply using the
system switch and/or the special cut-off devices.
• In case of a fault and/or poor operation, deactivate the unit
and do not try to repair it or directly intervene. Contact pro-
fessionallyqualiedpersonnel.Anyrepair/replacementof
theproductsmustonlybecarriedoutbyqualiedpersonnel
using genuine parts. Failure to comply with the above can
compromise the safety of the unit.
• This unit must only be used for its intended purpose. Any
other use is deemed improper and therefore hazardous.
• The packing materials are potentially hazardous and must
not be left within the reach of children.
• The unit must not be used by people (including children) with
limited physical, sensory or mental abilities or without expe-
rience and knowledge of it, unless instructed or supervised
in its use by someone responsible for their safety.
• The unit and its accessories must be appropriately disposed
of, in compliance with the current regulations.
• Theimagesgiveninthismanualareasimpliedrepresen-
tation of the ECOUNIT F. In this representation there may
be slight and insignicant differences with respect to the
ECOUNIT F supplied.
2. Introduction
ECOUNIT F is a vertical hot water storage tank with single coil (vers. 1C) or with double coil (vers. 2C).
This unit is designed for heating domestic hot water to a temperature below boiling point at atmospheric pressure and must
be connected to an energy source and a DHW system, compatibly with its performance characteristics and power.
PLACE OF INSTALLATION
The place of installation must be protected against frost.
The hot water storage tank must be placed in the immediate vicinity of the heat generator, to avoid pointless heat loss. Suitably
insulate the feed pipes.
PLUMBING CONNECTIONS
Carry out the relevant connections according to the cover diagram and the symbols given on the unit.
It is advisable to install the unit near the main hot water drawing point, in order to avoid heat loss along the pipes, and possibly
near a drain to facilitate any emptying operations.
The unit is arranged for connection to a recirculation pipe (ref. 20ing.5andg.6):thispipemustbeinsulated.Forrecircula-
tion, it is necessary to install a pump equipped with an operation timer or a minimum contact thermostat, to obtain its activation
on cooling of the recirculation water.
Iftheunionisnotused,tasuitableplug.
A relief valve (ref. 11ing.5andg.6)withsettingequaltoorgreaterthanthemax.DHWpressuregiveninthetechnical
data tablesonpagina26mustbeinstalledonthecoldwaterfeedpipeupstreamofthehotwatertank.
The connection pipe between the hot water tank and relief valve must absolutely not be shut off, as damage to the hot water
tank could occur due to overpressure.
 Thereliefvalveoutletmustbeconnectedtoafunnelorcollectionpipetopreventwaterspurtingontotheoorincase
ofoverpressureinthehotwatertankcircuit.Otherwise,ifthedischargevalvecutsinandoodstheroom,theboiler
manufacturer cannot be held liable.
Slight dripping from the relief valve is normal in the heating phase; therefore it is advisable to connect it to a drain with trap.
In case of a mains pressure near the valve setting values, a suitable pressure reducer (ref. 15ing.5andg.6)mustbetted
as far away as possible from the unit.
DHW expansion tank
The DHW expansion vessel must be sized according to the capacity of the hot water tank and the cold water pressure.
If the system has a pressure reducer, for the reason described above, and/or a check valve, it is necessary to install an expan-
sion tank (ref. 14ing.5andg.6)havingacapacitynotlessthan5%ofthehotwatertanknominalcapacity.
Do not install a check valve between the relief valve and the expansion tank. In general, to safeguard the unit and the system,
itisadvisabletoinstalltheexpansiontankwiththecharacteristicsdenedabove.
Fill the special expansion tank diaphragm chamber according to the manufacturer's instructions.

ELECTRICAL HEATING ELEMENT (1500W - 230V)
The heating element can be used as an auxiliary DHW heating system or as an antifreeze system. In the latter case, set the
heating element adjustment knob (“A”-“g.1”)tomin.(15°).Touseitforheatingwater,thethermostatknob“A” adjusts the
heatingtemperature(setpoint)oftheheatingelement,adjustablebetween15and75°C.
Theelectricalsystemmustbeinstalledbyaqualiedtechnicianaccordingtothelocalregulationsandinaccordancewiththe
applicable regulations in the building.
The system heating element must not be activated with the hot water tank empty! In this case the heating element
warranty is voided.
Fortheheatingelementelectricalconnection(see“g.1”):
- Remove the cover "D" by removing the screws.
- For the connection of the hot water tank heating element to the power supply, a cable “B” 3 x 2.5 mm2 (for 1.5 kW heating
element) is required.
- Run the end of the cable from the cable gland to the electrical part.
- Connect the wires to the terminals of the thermostat “C”. Reassemble everything.
Make sure the thermostat is properly applied to the heating element.
Thethermostattemperatureadjustmentrangeisfrom15°Cto75°C.Thethermostathasasafetydevicewhichintervenesif
thetemperatureexceeds93°C.

4. Maintenance and cleaning
Empty the unit before carrying out any maintenance operation.
GENERAL INSTRUCTIONS
To clean the external parts of the hot water tank, just use a cloth moistened with water, with the addition of liquid soap if necessary.
Do not use detergent powders and solvents (abrasives of any type, petrol and similar products).
Check the protection anode at least once a year (see next section).
If installed in places with risk of frost, the unit must be kept operating or completely emptied.
INSPECTION AND CLEANING INSIDE THE TANK
To clean the inside of the tank, empty the unit, and remove the cover (“D”-“g.1”)byundoingthescrews.
Removetheange(“F”-“g.1”).Duringcleaningbecarefulnottodamagethetankandexchanger(coil)enamel.
Cleaning can be done with a jet of water and, if necessary, with the aid of a suitable tool in plastic and wood to eliminate
stubborn sedimentation.
Rettheangesontheinspectionopeningswithrespectiveseals,checkingtheircondition(useanewsealifnecessary).
Relltheunitaccordingtothestartupinstructionsandcheckitstightness.
ANODE CHECK
The unit is protected against corrosion by a vitreous enamel coating of the inner surface and the exchange coil.
The hot water tank also has an anticorrosion magnesium anode to protect against the effect of eddy currents which could
damageit:thedurationdependsonoperationandthequalityofthewater.
The anode can be inspected (it is advisable to do this at least once a year) and is replaceable.
Tocheckand/orreplaceit,rstlyemptythehotwatertankasdescribedabove,thenremovetheblackplasticcoveronthe
upper end-plate of the hot water tank.
Toremovetheanode,itisnecessarytounscrewtheange“F”-“g.1”(tighteningtorque25-30Nxm).Afterinspectionand/
or replacement, the tightness of the hot water tank must be checked.
Replacement must be done with original parts.
