2.APPLICATION

Heat pumps Neore are intended for heating of houses or small industrial buildings. The product shall be
connected to low-temperature heating system, such as floor heating, wall or ceiling heating. Connecting of wall
heating convectors is possible but maximum temperature of heating water is limited to 50 °C. (60 °C at type HP)
However, efficiency is worse at this temperature (COP decreases). Heat pump can be also used for cooling.
At cooling mode is output water temperature limited to condensing temperature. Heat pump is not suitable for
cooling with water temperature under condensing temperature e.g. fancoil. Low temperature water causes
condensation on inner equipment of indoor unit and thereby the damage. Suitable cooling system cooling ceiling,
where condensation does not occur.

6. PRINCIPLE OF OPERATION

A heat pump is a device gaining low-temperature energy from a selected source and transforming it to a higher
temperature level. A heat pump air-water system utilizes heat of surrounding air. Its core is a high-performance
compressor which presses down the refrigerant in a hermetic circuit and expands it while using convenient
features of the cooling medium. We use ecological refrigerant R410. On the input side (outdoor unit and the
exchanger) outdoor air is pushed through heat transfer surface of exchanger by a fan. Inside of this exchanger
criculates refrigerant, which passes through expansion valve, and rapidly cooled to a temperature lower than the
ambient air. Refrigerant in exchanger heats up (e.g. from minute 17 to minute 10) and heat recovered is stored in
refrigerant. Then is "compressed" by a compressor and distributed to the condenser (indoor unit). Inside of plate
condenser of indoor unit refrigerant condenses and it transfers the heat into heating medium (heating water).
Thereafter condensed refrigerant goes into expansion valve and the cycle repeats itself.

7. INSTALATION

The device has to be mounted by an authorized company otherwise the device can be damaged or an injury can
be caused.The indoor unit shall be fixed on the wall. Free access to the controlling and protection elements has to
be provided (see the picture below). The outdoor unit shall be fixed by screws to the steel base supplied by the
producer. The steel base is required for a proper defrost of the exchanger. The base shall be fixed to ideally to a
concrete ground whose dimensions avoid falling the unit over during a gale.
Free circulation of air and maintenance access shall be provided (see the picture below). Be aware that outdoor
unit noise might disturb in the surrounding area and avoid it following proper standards.

BASE FOR OUTDOOR UNIT

The outdoor unit is recommended to be placed on a concrete base. The gap between breeze blocks shall be filled
with pebbles. It allows defrosted liquid to leak deep enough and avoids frozen lumps. If you have impermeable
ground, you can improve the condition by using a drainage pipe and spreading the liquid to a larger area.

8. CONNECTING OF REFRIGERATION CIRCUIT

Only authorized service can connect he refrigeration circuit (see Instalation).

WARNING!

Do not try to connect the circuit on your own! There is a threat of a serious injury. The refrigerant is under pressure
of 4,5MPa and temperature is up to -50 °C.

BIVALENT SOURCE

Heat pumps Neore contain integrated electric boiler of capacity 6kW. The boiler compensates power loss of the
heat pump at extreme conditions. When external bivalent boiler is used, it is necessary to equip it with all safety
elements (temperature protection, pressure valve, el. protection). The added bivalent source is controlled by the
heat pump only passively. It means it must contain its own regulation so that heating water temperature is not
exceeded, e.g. for the floor heating.

9. FIRST START OF THE HEAT PUMP

It is necessary to put water into the circuit before you launch the heat pump. Reach basic pressure 1 - 1.5 bar.
According to water column add 0.1 bar for every meter height of the heating system. Next, it is necessary to bleed
the circuit thoroughly. The bleeding is done by the bleeding screw of the circuit pump or, alternatively, on the upper
threaded piece of the board exchanger. When the circuit pump is switched on, the board exchanger shall be bled
thoroughly. After that its noise is decreased. The circuit pump shall run for 10 minutes at least before the
compressor is switched on. After watering and bleeding electric equipment shall be used.

Prim. equitherm. T - actual temperature computed by equithermal curve for primary circuit and access to equithermal

Equithermal curve - name explanation

Equithermal regulation is the kind of temperature regulation, where output water temperature from heat source

(heat pump) is set by outdoor temperature. The lower outdoor temperature means higher output water
temperature. It deliver significant savings in conjuction with a heat pump, which quickly lose effeciency as the
heating water temperature rises. If the equitermal regulation is properly set up guarantees temperature comfort
in the rooms in the form of temperature stability without fluctations.

In Neore heat pump are used two tools for comfort settings of equithermal curve:

1. Neo Equitherm - Automatic correction write down desired adjustment of heating water temperature without you
have to think about which value and how much to change.

2. IQ Equitherm - Automatic fine tuning of equithermal curve by difference of required and actual temperature of living
space. This tool is suitable for heating systems with good dynamics (radiators, fancoils, ceiling heating, etc.) At
heating systems with bad dynamics (floor heating, wall heating) is recommended to use regulation by standard
equithermal curve only .

The recommended procedure for setting equithermal curve:

1. Set default values of heating water of equitremal curve approximately as follows:

2. For example, if the room temperature is 2 degrees higher than required, enter the automatic correction eq. curve in
object section to -3°C. When the difference in room temperature eg about 1°C lower than required, enter the
correction + 2°C and so on. The maximum correction is +/- 3°C for one insertion. Controller itself modifies
equithermal curve by actual outdoor temperature. If another correction is needed, you enter it the same way. In
this manner you set all the equithermal curve and another change will not be necessary. Remember that change
takes effect after a certain time.

3. If the equithermal curve is set correctly, you can use IQ equitherm, which monitors set and actual temperature of
room and in case of difference automatically changes heating water temperature. It is suitable to cover
unexpected temperature gain (sun, fireplace, more people in room, etc.) or losses (wind, higher humidity of
outdoor air, etc.).

Correct settings of equithermal curve of heat pump is very important and benefit for really noticeable cost savings for

heating.

12. MAINTENANCE

This heat pump because of its construction requires really low maintenance. The basic maintenance will be
provided by service company once a year. During this service will be checked all crucial parts of the heat pump.
Especially the amount of refrigerant in circuit and refrigerant circuit function.

It´s important to check outdoor unit exchanger. You can clean it using garden washer with hot water. This way you
will clean it from raid of insects and any ice.

Don´t use high-pressure cleaners and any mechanical aids like brush etc. The exchanger is very soft
and could be damaged. Before cleaning of exchanger switch off the main circuit breaker in inside unit

The inside unit needs minimal maintenance. Use a damp cloth for cleaning its top cover and follow caution if the
heat pump is running and energized. We recommend to do indoor unit maitenance outside the heating season.

Check an activity of circulator before the heating season. Especially if it is not jammed. Once a year let
checked expansion vessel function, safety valve and heating water filter clogging.

You should better leave all these jobs to service company..

Disconnect heat pump from the mains voltage before you remove its cover. In other case threatening
injuries and eventually death because of electric shock.

For authorized person

This air conditioner uses new refrigerant HFC (R410A).

The instalation of the device is the same like instalation of devices with R22, R407, R134 refrigerant etc.
It´s necessary to keep these rules:

1 The pressure is about 1,6x higher than pressure with convectional refrigerants. Therefore is necessary to use

special instruments and measure equipment. It´s necessary to use copper pipeline with homologation for R410A
refrigerant for connection of inside and outside unit. If you work with refrigeration technology, you should
use protective equipment such as glasses, gloves etc.

2 This device with R410A refrigerant uses different service connection from convection refrigerants, which prevents

against connection of unapproved service tool. The connection for R410A refrigerant is 1/2 UNF (standard R410
accessories).

3 Don´t use pipeline which was used with another refrigerant or lubricating oil. The pipeline must be extremely clean

and dry. Storage and transportation of pipeline must be in closed state.

4 Filling and exchange of refrigerant must be in liquid state when the refrigerant is stable and both parts are added in

the correct ratio. The R410A refrigerant consists of two parts.

Special tool for R410A refrigerant

Description

The pressure is 1,6x higher. Using of these manometers for convection refrigerants may lead to their
destruction. These manometers have also different connection.

Service hose must be specially designed for R410A refrigerant.
It´s used convection vacuum pump with adapter for connecting to R410A refrigerant.
Leak detector must be homologated for R410A refrigerant.

This air conditioner uses new refrigerant HFC (R410A).

The instalation of the device is the same like instalation of devices with R22, R407, R134 refrigerant etc.
It´s necessary to keep these rules:

1 The pressure is about 1,6x higher than pressure with convectional refrigerants. Therefore is necessary to use

special instruments and measure equipment. It´s necessary to use copper pipeline with homologation for R410A
refrigerant for connection of inside and outside unit. If you work with refrigeration technology, you should
use protective equipment such as glasses, gloves etc.

2 This device with R410A refrigerant uses different service connection from convection refrigerants, which prevents

against connection of unapproved service tool. The connection for R410A refrigerant is 1/2 UNF (standard R410
accessories).

3 Don´t use pipeline which was used with another refrigerant or lubricating oil. The pipeline must be extremely clean

and dry. Storage and transportation of pipeline must be in closed state.

4 Filling and exchange of refrigerant must be in liquid state when the refrigerant is stable and both parts are added in

the correct ratio. The R410A refrigerant consists of two parts.

This device contains new HFC refrigerant (R410A)

HEAT PUMP CONNECTION TO HEATING SYSTEM

Designing
The heating system design quality is very improtant, as well as quality of heating water and used materials.
Insufficient flow of heat transfer medium causes increase in condensing temperature and thereby significant
reduction of COP (Coeficient Of Performance). Badly designed regulation system has the same effect. On the
other hand, too high flow causes erosion corrosion attack. Insufficient size of expansion tank is directly related
with possibility of corosion of heating system.

Installation and commissioning
Seemingly insignificant differences between project and realization may lead to malfunction of heating system.
Quality joints, soldering process, rinsing of heating system and first heating are good prerequisite for customer
satisfaction. Cost savings by installing heating system without people with appropriate qualification is intolerable
risk.

Used materials and devices
This problem is associated to project of heating system. Designer should avoid solutions where are used more
materials e.g. copper pipes, aluminium radiators and steel boiler. Such a system can not be protected against
various types of corrosion. Use of certified materials is always preferred. The same applies to seal, flux, solder
etc.. Total corrosion of heating system is very often caused by use of plastic pipes without oxygen barrier for floor
heating.

Heating water quality
Quality of heating water is decisive for long-term and trouble-free operation of heating system. Properties of used
water as heat transfer medium depends on location and type of water supply. It is important to note that water
with properties of drinking water mostly is not suitable to use as heating water without preparation. For heating
systems are important parameters like hardness, salinity, acidity and the content of dissolved gases.

Hardness of water means amount of Ca2+ and Mg2+ salt which during operation conditions changing solubility
and creates practically insoluble carbonates. Limescale forms mostly on bivalent source and negative effects
performs by the following mechanism. Initially creates thin thermal insulating layer. This layer decreases power
of source and also occur local overheating. From unequal dilation at the spot of overheating, compactness layer
is breached. Chipped limescale pieces get into the water and gradually clog refrigerant exchanger and regulation
valves. Carbon dioxide arises during the build up of limescale and causes occurence of air inside of system and
surface corrosion, if the conditions are good. Moreover it is necessery to fill water missing.That is not mostly
adapted and it brings the system into further adverse effects.

Salinity expresses amount of all dissolved salt in water. In practise it is the cations Na+, K+, Fe2+ and anions
Cl- and SO42-. Ions of Fe2+, Cl- a SO42- does not support corrosion of heating system. Water salinity is directly
proportional to its elecctrica conductivity. High values of water salinity helps to electrolytic corrosion especially
when are used more different types of material in heating system (copper, steel).

Acidity of water (pH) is significant criterion for corrosion behavior of system. Because of minimizing corrosion
efficiency, the value of pH of used water should match used materials. It is important to note that pH suitable
for steel is not suitable for example for aluminium etc..

Amount of dissolved gases in water depends on its temperature and pressure of gases. At heating water it is
mainly about dissolved air contains primarily N2, O2 and CO2. From chemical point of view nitrogen in heating
sstem is harmless. But from operation point of view affects adversely. Decreases thermal capacity of water,
increases the compression work and causes cavitation noise. Oxygen and carbon dioxide active corrosion and it
is needed to remove from the water. The most of dissolved gases could be removed from heating system by
bleeding. But it is not possible to remove gases from heating water completely.
If the system is bleeded correctly, a rest of gases in water have do not have got underlying influence to long-term
lifetime and reliability of heating system. Residual oxygen is consumed during corrosion and than corrosion is
stopped. The biggest danger is repeated intrusion of oxygen into system. In practise is this fact the most often
cause of corrosion of system. The reason could be bad tightness of system, wrong parametres of expansion tank,
quality of sealing elements and used plastic parts. Keep in mind that etc. floor heating made from plastic with an
oxygen barrier conforming to norm is not 100% resistent against the diffusion of oxygen. In this case occurs the
oxygen intusion repeatedly corrosion never stops spontaneously. Use of oxygen absorbing component is needed.

27

Principles of commissioning and operation of heating systems
In modern heating systems is important to take care of heating water quality, install, commisioning and operation.
Otherwise rapidly and clearly show problems. The aim of this part is to warning about rules which are related to
this problematic.

1) The quality of filling and heating water
Valid norm dealing with water quality ČSN 07 7401 is binding for heating systems with heating power below 60kW
and maxima heating water temperature of 115°C. Water adapted by this norm perfectly responds to heating
systems with lower power. Water modification by the norm is not realistic at small heating systems (flats, family
house).
It is advisable to follow the following recommendations:
* use of water with hardness lower than 5,6 N0 and conductivity lower than 0,5 mS/cm
* circulation water pH set by corrosion resistance of used materials in heating system

Steel corrosion:

- at pH higher than 8,5 is satisfactory

- at pH higher than 10 is insignificant
Copper corrosion:

- at pH higher than 10 is consiredable

- at pH from 8,5 to 9 is reasonable
Aluminium corrosion:

- at pH higher than 7,5 is considerable

- at pH from 6,5 to 7,5 is acceptable

* when drinking water is used, it is necessary to apply anto-corrosion chemicals for water hardness stabilisation
* if there are used more kinds of material inside of heating system (copper, aluminium, steel) is required use of
special chemicals for a specific system
*at least once a year (before heating season starts) is needed to check chemicals content and replenish
as needed

2) Rinsing of new heating system
Norm ČSN 06 0310 about design and install of central heating according to article 132 prescribes rinsing of
system before testing and commisioning. Sense of this obligation is to remove impurities from heating system.
That means mainly mechanical impurities, fats,oils, residual products after welding and soldering. The exact
procedure is not defined and therefore we recommend:

* for rinsing use softened water (max. 5,6 N0), if it is possible; drinking water without treatment is usable as well
* add suitable, not foaming, degreasing detergent into water for remove of fats and oils (only cold or hot water is
not able to remove fats and oils)
* set maximal water flow (all reduction valves are open, maximal circulator power)
* heat the heating system by half-power of boiler to ca. 6°C (slow heating up is particularly important when is not
used softened water for minimization of limescale)
* after heating up keep system in operation for 30 minutes
* when system cools down under 40°C, you can drain water in compliance with the law on waste water
* clean up filters of mechanical impurities
* immediately begin to ful fulfilling the system by permanent filling

3) Settings of pressure parameters of expansion tank
Chosen volume and pressure parameters of expansion tank are very important for long-term and trouble free
operation of heating system. Necessary volume of expansion tank is selected by ČSN 06 0830. Insufficient
volume and pressure ratios leads to repeated aeration and corrosion of heating system. The heating system
designer should guarantee the right volume of expansion tank. To installation company we recommend to set
pressure parameters as following. User should to check this parameters once a year.

Gas overpressure (Pn) in expansion tank

* overpressure setting must be done with empty expansion tank (without water)
* pressure Ps of expansion tank is defined as sum of pressure of static water column Pst and 0,2bar
(pressure Pst is defined as difference betweeen expansion tank and highest point of system -> 1m = 0,1bar)

Heating (filling) water pressure (Pf) settings

* enable seamless filling of system by opening all regulation valves
* filling water pressure Pf should be about 0,3 - 0,5bar higher than gas pressure Pn in expansion tank; filling water
pressure is checked in cold state by manometer at water side after bleeding

28

Settings of safety relief valve (Psv)

* presssure of safety valve Psv should be about 0,5bar higher than operation pressure Pe; it is pressure inside
of system when is heated to its maximum; this condition suits for pressure Psv < 5bar; for pressure Psv > 5bar
suits Pe + 0,9 Psv

4) Heating system bleeding
Bleeding is carried out when heating system is filled, commisioning and operated
We recommend to comply wiht the following:

* during filling heating system do the bleedinf continuously
* final bleeding do with maximal operating temperature of heating water
* bleed at all bleeding points ca. 5 minutes after curculator is stopped
* repeat bleeding after a few days of operation

5) Heating system commisioning
Fill the heating system with permanent filling (modified by step 1) and after successfull leak test you could start
commisioning. We adhere to the following principles:

* first heating is needed to do with slow power increace
* bleed by the previous step
* make the operational tests in the agreed scope (between the investor and implementer)

6) Heating system operation
First heating season is mostly connected with heating test and regulation system. We recommend sticking to
these principles:

* check tightness of the system; do not fix defects by water adding
* check filters and clean up if needed
* drain system just in case of needed repair and keep empty for shortest possible time
* use antifreeze liquid as filling medium in case of danger of frost; do not drain the system
* periodically check and maintain all parts of system (circulator, boiler, regulating elements, expansion tank)
* check the heating water quality and add chemical substance if needed at the beginning of the heating season

Technical possibilities and chemical protection of hot water heating systems

Influence of hard, not modified water and related corrosion process in heatiting system is generally known. There
are a lot of manufacturers of "heating chemistry and equipments" for modification of heating water, anticorrosive
protection and cleaning of heating systems

Selection can not recommend the manufacturer. User and manufacturer are joinly responsible for selection,
method of application and technical effect. Select "heating chemistry" carefully and your selection consult with the
manufacturer. Proper selection can be made only if you know all parameters of heating system as hardness and
acidity of heating water, material composition of heating system (steel, copper, etc.), type of heating system
(gravitation system, forced circulation with expansion tank, floor heating, etc.). It is also important to abide dosing
for first and the following doses. Professional product should be supplied together with methodology for
determination of the actual concentration in water.

Heating water can be also modified by cation ion exchanger or by reverse osmosis, but it is economically too
denanding. Cause of the same reason is practically used for small systems only magnetic modification, which
prevent of limescale only.

Frequently asked question is how to put "heating chemistry" into system. Except resourcefulness of instalation
companies there are professional vessels for dosing.

Hydraulic circuit design documents

The Neoré heat pump is designed according to the simple installation. All important elements of the hydraulic
circuit are integrated in the indoor unit. The indoor unit contains efficient circulator, exchanger, 3-way valve for
heating DHW, 8 l expansion tank, 6 kW backup electric heating, DN20 / 2,5bar safety valve. In the hydraulic circuit
design is neccessary to take into account high demand of heat pumps on sufficient flow of heating water. The heat
pump NeoRé can operate without accumulation tank.
In this case is neccessary to keep following demands. The heat pump musn´t be exclude from the heating system.
The heat pump has to have enough amount of thermal energy which will be taken back during defrosting of the
outdoor unit. It is not recommended to use thermostatic or mixing valve (typically 4-way valve). Regulation of
heating water is determined by equitherm regulation which is contained in the inside unit control system. In the
case of need to use flow regulation element, it is necessary to install accumulation tank into system. We do not
recommend to use hydraulic dynamic pressures flattener (anuloid) for heat pump connection to the heating
system. If you use it, the efficiency of heat pump becomes worse because of its temperature gradient. Anuloid use
only for connecting bivalent source to the heating water circuit (if is needed). In case of use accumulation tank is
necessary to ensure the same flow between primary and secondary side of hydraulic circuit (at least at full load).
The size of accumulation tank is recommended at least 14,6 l on 1 kW of heat pump power.

The heat pump contains circulator with variable power. Minimal water flow which is required to heat pump
operation is shown in following graph.

Freeze
protection

Static (output water
temperature lower than 5°C)

If the indoor unit is connected to power
supply, output water temperature
is monitored. When it is lower then 5°C,
so circulator and first stage of bivalent
(2 kW) are switched ON. When temperature
exceeds 5°C, protection is switched OFF.
This protection is active also when heating /
cooling is not switched ON. Protection is solid
and works only when indoor unit is connected
to power supply and breaker of technology
is switched ON. Outdoor unit is not used.

During operation (adjustable
in service access)

When during heating temperature become
lower than set temperature (15°C default),
outdoor unit is shut down. Output water
heating takes over bivalent source. After
exceeded output water temperature of 15°C,
bivalent source continues in heating for
another 30 minutes. Then heating control
continues in the usual manner. This protection
is mostly activated when defrost and water
flow is insufficient (eventually when is low
energy accumulated inside of system).

For compliance declared effectivity
and ensuring safe operation sufficient water
flow is necessary. Minimal water flow
is defined by relationship among outdoor unit
power and required power of circulator.
