sulphurousacidgas)is produced.Corrosionof

copperpipes orsolderedparts maycause the

refrigerantto leak.

1.3.3 Refrigerant

If applicable.Seetheinstallationmanualofyour

applicationformore information.

WARNING

Duringtests,NEVER pressurize the product with

a pressurehigherthanthe maximum allowable

pressure (as indicatedon thenameplateofthe

unit).

Installation and user manual

WARNING

Take sufficientprecautions in caseofrefrigerant

leakage.If refrigerantgas leaks,ventilatethe

areaimmediately.Possiblerisks:



Excessive refrigerant concentrations in a

closed room can lead to oxygen deficiency.

Toxic gas maybe producedif refrigerant

gas comes intocontactwith fire.

DANGER: RISK OF EXPLOSION

Pump down –Refrigerant leakage.If you want

to pumpdown the system,andthere is a

leakageinthe refrigerantcircuit:

Do NOT usethe unit's automaticpump

down function, withwhich you can collectall

refrigerantfrom the system intothe outdoor

unit. Possible consequence: Self-

combustionand explosionofthe

compressorbecauseofairgoingintothe

operatingcompressor.

Use a separaterecoverysystem so that the

unit's compressordoesNOThave to

operate.

WARNING

Always recover the refrigerant.Do NOT release

them directlyinto the environment.Use a

vacuum pumpto evacuate the installation.

NOTICE

To avoid compressorbreakdown,doNOT

charge more thanthe specified amountof

refrigerant.

When the refrigerantsystem is tobe

opened, refrigerantmustbetreated

accordingto the applicablelegislation.

WARNING

Make sure there is no oxygen in the system.

Refrigerant may only be charged after performing

the leak test and the vacuum drying.

In case re-charge is required,refer to the

nameplateofthe unit. It states the type of

refrigerantandnecessaryamount.

The unit is factory charged with refrigerant and

dependingonpipesizes and pipelengths some

systems requireadditionalcharging ofrefrigerant.

Only usetools exclusivelyfor the refrigeranttype

usedinthe system,this to ensurepressure

resistance andpreventforeignmaterials from

enteringintothe system.

Chargethe liquidrefrigerantas follows:

Then

A siphontubeis present

(i.e., the cylinderis marked

with "Liquidfilling siphon

attached")

Chargewiththe cylinder

upright.

A siphontubeis NOT

present

Chargewiththe cylinder

upsidedown.

Open refrigerantcylinders slowly.

Chargethe refrigerantinliquidform. Addingit in

gas form mayprevent normal operation.

CAUTION

When the refrigerantchargingprocedure is done

or when pausing,close the valve of the

refrigeranttank immediately.If the valve is not

closedimmediately,remainingpressuremight

charge additional refrigerant.Possible

consequence:Incorrectrefrigerantamount.

Make sureto installearthwiring.DoNOT

earth the unitto a utilitypipe,surge absorber,

or telephoneearth.Incompleteearthmay

causeelectrical shock.

Make sureto useadedicated powercircuit.

NEVER useapowersupplysharedby

anotherappliance.

Make sureto installthe requiredfuses or

circuit breakers;

Make sureto installanearthleakage

protector. Failureto do somaycause electric

shockor fire.

When installingtheearthleakageprotector,

makesureit is compatible withtheinverter

(resistanttohighfrequencyelectric noise)to

avoid unnecessaryopeningofthe earth

leakageprotector.

NOTICE

Precautions whenlayingpowerwiring:



Do not connect wiring of different thicknesses

to the power terminal block (slack in the power

wiring may cause abnormal heat).

When connectingwiringwhich is the same

thickness,do as showninthe figure below.

For wiring,usethe designatedpowerwire

andconnect firmly, then secure to prevent

outsidepressurebeingexertedonthe

terminalboard.

Useanappropriatescrewdriverfor

tighteningtheterminalscrews.

A screwdriverwith a smallheadwill

damagethehead andmake proper

tighteningimpossible.

Over-tighteningthe terminalscrews may

breakthem.

Installpowercables atleast1 metreawayfrom

televisions orradios topreventinterference.Depending

on the radiowaves,a distanceof 1 metre maynotbe

sufficient.

WARNING

After finishing theelectrical work,confirm

that each electrical componentandterminal

2.4 Operating principle

The equipmentbelongingtothe 1.9 kW and 2.9 kW

series is capable ofproducingdomestic hotwater

mainlyby usingheatpumptechnology.A heatpump is

capable of transferringthermalenergyfrom a low

temperaturesourcetoanotherwith a higher

temperature and vice versa (heat exchangers).

The equipmentusesa water circuit consisting ofa

compressor,anevaporator,a condenseranda

lamination valve; a liquid/gas coolantflows insidethis

circuit (seeparagraph4.6).

The compressorcreates adifferenceinpressureinside

the circuit that allows a thermodynamiccycle to be

obtained:this sucks thecoolantfluid in throughan

evaporator, wherethe fluid itself evaporates at a low

pressure byabsorbingheat,it is compressed and

driven towards the condenserwhere the fluid

condensesata highpressurereleasingthe absorbed

heat. After the condenser,thefluidpassesthroughthe

so-called “laminationvalve”andby losingpressureand

the temperature starts to vaporise,it re-enters the

evaporator andthe cycle starts all over again.

Installation and user manual

Page9

Fig. 1 –Operatingprinciple

The operatingprincipleofthe equipmentis as follows

(Fig. 1):

I-II: The coolantfluid suckedinby the compressorflows

inside the evaporatorand while it evaporates,it absorbs

the “ecological” heat given by the air.

At the sametime,theambientairis suckedin by the

equipmentbya fan; the airloses itheat by passingover

the finned-tubebatteryof the evaporator;

II-III: The coolantgas passes inside the compressor

andit undergoes anincreaseinpressurethatcauses a

riseintemperature;transforming this intosuperheated

steam;

III-IV: Insidethecondenser,thecoolantgas releasesits

heat to the water insidethe tank (boiler).This exchange

process makesitpossibleforthecoolantto pass from

superheatedsteamtoaliquid stateby condensingata

constantpressureandundergoing a reductionin

temperature;

IV-I: The liquidcoolantpasses throughthelamination

valve, it undergoes asudden dropinbothpressureand

temperature andit partiallyvaporises bringingpressure

and temperature backto the initial conditions.The

thermodynamiccyclecan begin.

2.5 Available versions and

configurations

The heat pumpis available,in relationto the thermal

power(1.9 kW version),which can be setup in different

configurations,depending on the possibleintegrations

with otherheatingsources (e.g.solarthermal,biomass

power,etc.).

Positions permittedfortransporting andhandling:

WARNING!

During the product handling and installation stages,

it is forbidden to put the upper part of the device

under any kind of stress whatsoever due to the fact

that it is not of a structural nature.

WARNING!

The equipm ent can be transported horizontally

only during the last km according to what indicated

abov e (see “Positio ns permit t ed for transporting

and handling ”) and taking care of posit ionin g som e

supports on the lower side of the boiler in order

not to lean against the upper part, which is not of a

structural nature. When the equipment is

transported horizontally, the display must be

oriented toward the upper side.
