3. Appliance description

The appliance is an air/water heat pump consisting of an indoor unit and an outdoor unit. The appliance can be used to heat a building and provide domestic hot water (DHW).

3.1 Functionality

An air/water heat pump extracts thermal energy from the ambient air (low temperature) and transmits it together with electrical drive energy in the form of useful heat (higher temperature) to a heating and/or DHW circuit.

The heat pump consists of separated circuits linked together via heat exchangers:

► Heat source circuit (extracting heat)

► Refrigerant circuit

► Heat sink circuit (supply of heat to the central heating

and/or DHW)

The operating principle of an air/water heat pump:

1 Evaporator (n heat exchanger) 2 Compressor 3 Condenser (plate heat exchanger) 4 Expansion valve 5 Heat sink (heating, DHW) 6 Air as heat source

3.2 Appliance components

3.2.1 Indoor unit

6 www.ochsner.com | 982000-AIR-M2-M4-EN03.1

The indoor unit is intended to be installed only inside the building. The indoor unit contains the compressor, which in terms of sound technology is acoustically decoupled a number of times from the casing. The casing is acoustically optimised and allows particularly quiet operation.

OPERATION | Appliance description

i

11_02_200_214_01_004

Compressor

The fully hermetically sealed compressor is designed for high efciency heat pump applications. A suitable starting current limiter for the compressor is installed in the indoor unit.

Electric booster heater

The appliance is tted with an electric booster heater

(immersion heater). At low outdoor temperatures, the appliance operates in bivalent-parallel mode. The appliance can also be combined with an additional heat generator.

Condenser

The condenser takes the form of a plate heat exchanger, which is built of stainless steel and insulated on all sides against condensation and heat loss.

3.2.2 Outdoor unit

The outdoor unit is intended to be installed outside. The outdoor unit is designed as a horizontal split evaporator. The indoor unit is connected to the outdoor unit with refrigerant lines, along with electrical control and power supply cables.

► 1x direct circuit (heating and/or cooling)

► 1x mixed circuit (heating and/or cooling)

► 1x directly heated DHW cylinder (with electric booster

heater)

► 1x heat pump (heating and cooling)

► 1x additional heat generator (electric booster heater

or enable contact for external heat generator)

3.3 Name plate

Two name plates are attached to the indoor unit to identify your heat pump. In addition, a label with the serial number is attached to the right-hand casing panel of the appliance.

2

Evaporator

The evaporator is a part of the outdoor unit and consists

of copper pipes in a set of aluminium ns.

Information

With an air/water heat pump, frost may form on

the evaporator ns of the outdoor unit, depending

on the air temperature (below approx. +7°C), air humidity and the operating point. The evaporator

ns are automatically de-iced again in the cyclical

defrosting mode of the heat pump.

Fan

The outdoor air is blown across the evaporator by a quiet fan.

3.2.3 Heat pump control unit

The OCHSNER heat pump controller includes devices for controlling heat pump heating systems with a cooling function as well as DHW heating. In its standard version, the heat pump control unit consists of the OTE controller and the master controller, both of which are installed in the indoor unit.

the specied safety devices.

Ensure easy access to the safety devices. It

»

must be possible to perform an emergency shutdown at all times.

8 www.ochsner.com | 982000-AIR-M2-M4-EN03.1

4.1 Operating costs

In the rst two heating seasons, higher running costs are

to be expected (up to 50% more, depending on residual moisture in the building). Enabling the screed drying program will also increase operating costs further.

4.1.1 Flow temperatures

For optimum operation of your heat pump, you should aim

for the lowest possible heating ow temperatures (and also

DHW temperatures). The maximum system temperature for your heat pump should be restricted to 60°C.

Information

Increasing the room temperature by 1°C results in an increase in consumption of 5-7%.

4.1. 2 Ventilation

Any ventilation should be intermittent, especially during the heating period, and according to your own require-

OPERATION | Maintenance and care

i

ments. Intermittent ventilation is considerably more energy

efcient than permanent ventilation, and therefore saves

money. Avoid permanent ventilation.

4.1. 3 Heating setback program

From an energy efciency point of view, using a time pro-

gram to reduce the heating ow temperature is especially

not recommended for air/water heat pumps with low tem-

perature heating systems (such as underoor heating).

These systems are slow to respond and, due to the addi-

tional output from the system required following the end

of the setback phase, it is possible that the second heat

generator (boiler, electric immersion heater) will cut in. This

can lead to higher operating costs.

5. Maintenance and care

We recommend an annual inspection and if necessary

have your heat pump serviced by OCHSNER Customer

Service.

Material damage

Maintenance work on electrical components of the

heat pump may be carried out only by qualied

contractors.

Material damage

Abrasive tools must not be used to clean the evap-

orator ns in the outdoor unit.

Any dirt on the ns should be blown away

»

using compressed air (max. 8 bar), in the di-

rection of normal air ow. If the ns are very dirty, contact your OCHS-

»

NER system partner or OCHSNER Customer Service.

If it is necessary to clean the casing sections of the

»

indoor or outdoor unit, use only a damp cloth (with water or a weak soapy solution). Do not use any abrasive or aggressive cleaning materials.

During the building phase, protect the indoor and

»

outdoor units from dirt and dust with a suitable cover. Use the plastic cover provided.

Ensure that the heating circuit is lled with sufcient

»

water.

Ensure that any condensation beneath the outdoor

»

unit can drain away without freezing all year round.

Information

If the outdoor unit is covered with a thick layer of snow, this can reduce system efciency.

Remove snow on and around the outdoor unit

»

as necessary. If required, install the snow cover available as

»

an accessory for the outdoor unit.

Information

Ensure that the refrigerant circuit of your heat pump is tested for leaks once a year (in acc. with Regulation (EU) no. 517/2014).

Ensure year-round access to soldered joints in

»

the refrigerant circuit. Document the results of the leakage test in the

»

system test report.

6. Problem solving

Problem Cause Solution

Too little DHW is available or the central heating system is too cold.

The appliance is leaking water.

If you have a problem that you cannot resolve, contact

the system installer, a qualied contractor or OCHSNER

Customer Service.

Faults are displayed as”Er XXX”on the master controller of the OTE control unit. If a fault occurs, contact your system installer. The system installer knows your hydraulic system and how it operates. The causes of faults can often be found in the settings or in the hydraulics.

Before contacting the installer, make a note of the serial number and the heat pump model. The serial number and heat pump model of your appliance are shown on the name plate. The name plates are attached to the back of the appliance on the outside and behind the front appliance casing panel (control box outer side).

9. Preparing to install the appliance

Before installing the indoor and outdoor units, preparatory

work needs to be carried out by qualied contractors.

9.1 Indoor unit installation location

Material damage

The indoor unit is intended to be installed only inside the building. It must not be installed in rooms with high levels of humidity (permanently above 70%).

Information

Plan the installation sites for the outdoor and indoor units such that the pipework carrying the refrigerant is as short, straight and simple as possible.

B

A ≥ 1000 mm B ≥ 500 mm C ≥ 500 mm D ≥ 50 mm E ≥ 500 mm

D

E

C

A

The installation location for the indoor unit must meet the following requirements:

► A dry and frost-free room

► Sound optimised environment

► A horizontal, adequate load bearing oor (for weight

of indoor unit, see „Specication“ on page 50)

► Not situated directly below or above bedrooms

► Max. room temperature 30°C

► The installation room must not be subject to a risk of

explosions arising from dust, gases or vapours.

9.1.1 Keep minimum clearances

Observing the specied minimum clearances for the indoor

unit ensures:

► Correct installation of the appliance

► Fault-free operation

► Ability to carry out maintenance on the appliance.

9.2 Outdoor unit installation location

Information

Plan the installation sites for the outdoor and indoor units such that the pipework carrying the refrigerant is as short, straight and simple as possible.

Information

When laying refrigerant lines in the ground, schedule the work so that the pipe liner can be laid together with the already inserted refrigerant lines in the trench between the outdoor and indoor units.

- If the pipe liner is laid empty, inserting the re-

frigerant lines afterwards will be difcult if not

impossible.

The outdoor unit is intended to be installed only out of doors. Please note the following with regard to the installation location of the outdoor unit:

► Select the outdoor unit installation location such that

the appliance is safely accessible from all sides all year round.

► Avoid installing it in a hollow or ditch (a “pool” of cold

air).

► An optional snow cover is available to protect the

outdoor unit fan in case of heavy snowfall. Where necessary, ensure that a snow cover is installed (according to installation site and local weather conditions).

982000-AIR-M2-M4-EN03.1 | www.ochsner.com 13

INSTALLATION | Preparing to install the appliance

i

Material damage

The air ow through the evaporator must not be

obstructed by surrounding buildings. A reduced air

ow rate can lead to loss of efciency in the system.

Please note the following with regard to installation in coastal areas:

► The standard design of outdoor unit must be installed

at least 1 km from the sea.

9.4 Preparing the refrigerant lines

Information

If the appliance, the refrigerant lines, the pipe xings and the wall outlets are not installed correctly, structure-borne sounds can be transmitted to the building.

Ensure that the refrigerant lines are in-

»

11_06_200_202_006

stalled in a way that ensures insulation from structure-borne noise. The system installer carrying out the work is responsible for this.

Material damage

Use only copper pipes suitable for refrigerant (D IN 12735-1). Thin-walled pipes run the risk of bursting.

Please observe the stipulated diameters and

»

wall thicknesses of the copper pipes.

Material damage

Incorrect or premature opening of the pipe connections and cutting of the refrigerant lines can allow dirt and moisture to enter the refrigerant circuit.

Do not open the connections on the indoor

»

or outdoor units until just before installing the refrigerant lines. Cut the refrigerant lines with a suitable pipe

»

cutte r. Prevent swarf from contaminating the pipe

»

connections and refrigerant lines. Once cut, ll the refrigerant lines with a sub-

»

stance such as nitrogen. Keep the refrigerant lines closed until just be-

»

fore installation.

Pipe connections for the refrigerant lines (suction gas and liquid lines) are supplied soldered closed, both for the indoor unit and the outdoor unit. Appropriate copper pipes for refrigerant lines are supplied sealed at both ends and

lled with nitrogen.

Please note the following with regard to routing of the refrigerant lines:

Keep to a minimum the distance between the indoor

»

and outdoor units, in order to minimise heat loss from the refrigerant lines.

Select the installation sites for the indoor and outdoor

»

units such that the maximum permissible line lengths and height differentials are not exceeded.

Avoid routing the lines in the vicinity of bedrooms.

»

The refrigerant in the lines can generate noise under certain operational conditions.

9.4.3 Preparing the wall outlets

Whether the refrigerant lines between the indoor and outdoor units are to be routed above or below ground, ap-

propriate and plant-specic wall outlets need to be created

through the outer wall of the building.

Ensure that the wall outlets are constructed in an ap-

»

propriate, plant-specic manner.

Take the construction of the wall (tiles, concrete) into

»

account.

Take the prevailing groundwater situation into

»

account.

Material damage

Incorrectly created wall outlets can cause signicant damage to property, due to water (seepage, condensation, floodwater) penetrating into the building or stonework. Where the wall outlets are created below ground level, the breach must be appropriate to local conditions at the site (e.g. non-accumulating or accumulating seepage water, groundwater under pressure).

Use a suitable pipe liner or wall sleeve for the

»

wall outlet. Tie the external end of the wall outlet in to the

»

external waterproof seal of the building. Ensure that the pipe liner is arranged with a

»

slight fall (at least 2%) to the outside. On both the outside and inside edge of the

»

wall, use appropriate ring seals to seal the space between the wall sleeve and the refrigerant lines and electrical cables passing through.

Shutdown by means of a tariff contactor

In the case of shutdown by means of a tariff contactor installed on behalf of the customer (sealed by the PSU), the power supply to the heat pump compressor is disconnected. Here, it is essential to connect an auxiliary contact to the tariff contactor (N/C contact) of the PSU signal contact on the indoor unit.

Night tariff

Where tariff switching takes place within the meter (night tariff), the PSU signal contact is not connected.

Information

Ensure that the guard is easy to clean for maintenance purposes. A heavily soiled strainer can lead to a high pressure safety shutdown or to a malfunc-

tion shutdown based on ow metering (heat sink).

Information

Ensure that the ow velocity in the pipe network

does not exceed 0.8 m/s, as this can cause increased noise emissions.

10 . 3 .1 Connecting the heating water

Before connecting the heat pump, ush the pipework

»

through with ltered ushing water in accordance with

standard procedures. Foreign bodies such as rust, sealing material and swarf will impair the operational reliability of the heat pump.

10.3 Connecting the heat sink system

Information

The hydraulic connection from the heat sink system (WNA) to the heat pump may be made only by a

qualied contractor.

Information

For maintenance purposes, a cut-off valve should be tted to every hydraulic line close to the connection point on the heat pump.

In the case of air/water heat pumps, an appropriately dimensioned heat pump buffer tank is essential, in order to provide the necessary energy for defrosting the outdoor unit.

► The pipe network and the pumps should be correctly

dimensioned for your heating system and according to the technical data for your heat pump.

► A (manual) air vent valve must be tted at the highest

point in the pipework.

► At the lowest point in the pipework, t a drain pipe to

allow the system to be drained.

Quality of heating water

Use the corre ct ll water that is suit able for the compone nts

of your heating system. We recommend ll water prepared

according to Guideline VDI 2035-2.

A high pH value and low electrical conductivity in the ll

water will reduce to a minimum the risk of corrosion to iron

and copper materials, as long as there is also low oxygen

content. This will also minimise scaling (calcication).

► Ensure that no foreign bodies (dust, dirt etc.) can en-

ter the pipework.

► A guard (strainer) can be installed in the return line of

the heat pump to catch dirt.

10.3.2 Safety valve drain

Information

The indoor unit has an internal safety valve (DHW, heating).

Observe national and regional regulations re-

»

garding the design of the drain and prescribed regular operational tests.

Information

The maximum operating pressure of the heat transfer medium is 3 bar. However, due to closing pressure differences, the safety valve may begin to open from a pressure of 2.4 bar.

If the valve is triggered, the water exits via a hose on the rear of the indoor unit.

The safety valve drain should be dimensioned such

»

that the water can drain unobstructed via an open and readily visible waste water drain.

10.3.6 Cooling version

When used for cooling, all system components (pipes,

ttings) must be insulated against condensation build-up

using appropriate insulating materials. This is particularly

important on the ow line from the heat pump to the heat

pump buffer tank.

Especially in relation to cooling mode and defrost

mode, ensure adequate sizing of the hydraulic safety devices.

Allow for a pressure maintaining device with appro-

»

priate charge pressure, adjusted for the operating conditions.

Ensure that in cooling mode the appliance casing on

the indoor unit is fully and correctly installed (see „Assembling the appliance casing“ on page 27).

10.3.7 Connecting the DHW

11_02_200_202_01_029

The indoor unit is tted with a 3-way switching module for

switching between the DHW circuit and the heating circuit.

When conguring a DHW charging pump, take into account

the internal pressure differences in the plate heat exchang-

er (see „Specication“ on page 50).

10.3.4 Diaphragm expansion vessel (DEV)

► The indoor units for the AIR 7, AIR 11 and AIR 18

heat pumps are factory-tted with a 24 l diaphragm

expansion vessel for the heat sink system.

► The factory-set pre-charge pressure on the DEV is

1.5 bar.

Information

The set charge pressure on the DEV must not be taken as correct but must be adjusted for the particular system.

Set the charge pressure on the DEV accord-

»

ing to the height of your system and the lling

pressure of your heating system.

10.3.5 Flow metering

A ow meter is installed on the heat sink side inside the

indoor unit of your heat pump. This unit measures the ow rate in your heating system. Too low a ow rate will lead to a safety shutdown of the heat pump.

seals on the wall outlets are correctly tted.

Material damage

Incorrect or premature opening of the pipe connections and cutting of the refrigerant lines can allow dirt and moisture to enter the refrigerant circuit.

Do not open the connections on the indoor

»

or outdoor units until just before installing the refrigerant lines. Cut the refrigerant lines with a suitable pipe

»

cutte r. Prevent swarf from contaminating the pipe

»

connections and refrigerant lines. Flush the refrigerant lines fully with nitrogen.

»

The refrigerant circuits on both the outdoor and indoor

units are lled with nitrogen at the factory. Please note the

following when installing the refrigerant lines:

Use the largest possible pipe bends to avoid high

»

pressure losses.

Use suitable sound-insulating pipe xings to secure

»

the refrigerant lines.

Do not install the pipe xings in the vicinity of bends

»

in the pipes.

Ensure that no strain can be exerted on soldered

»

joints.

Material damage

Operating the heat pump with too little or no refrigerant will damage the appliance.

10.5.4 Insulating the refrigerant lines

11_02_200_202_01_018

Insulate refrigerant lines with suitable insulating mate-

»

rial wherever they are still exposed to the air between

the indoor and outdoor units, to prevent formation

of condensation. When passing through open air

outside, the insulating material must also have UV

protection.

Information

Insulation used beneath the soil must be made of a closed-cell material. Otherwise, the thermal insulation of the material will be impaired.

When soldering, ensure that neither moisture nor dirt

»

can penetrate into the refrigerant lines. When soldering, always use forming gas.

Ensure that soldered joints are properly sealed.

»

10.5.2 Checking for leak tightness

After the refrigerant lines have been installed, the leakage test on the refrigerant circuit is carried out.

Information

Nitrogen can become trapped in magnetic valves and expansion valves in the refrigerant circuit.

Before carrying out the leakage test, open all

»

magnetic valves and expansion valves in the refrigerant circuit.

Evacuate the refrigerant lines.

»

Use a suitable medium to carry out the leakage test

»

according to standard regulations.

i

11. Commissioning

OCHSNER Customer Service or an authorised customer service partner must be requested to commission the system. In order to be allocated an appointment, a completed and signed commissioning form must be provided. Commissioning appointments must be requested at least two weeks in advance.

11.1 Before switching on for the rst time

The heat pump has no separate on/off switch. In an emer-

gency, the system must be shut down via the specied

safety equipment. The safety equipment must be accessible so that an emergency shutdown can be performed at any time.

WARNING: Electrocution

First-time start-up of electrical systems is permitted

only in the presence of a qualied contractor.

Make sure that no persons can be put at risk during

»

the rst start-up.

Make sure that the heat sink system (heating and

»

DHW production) has been connected to the heat pump.

11.3 Adjusting the ow rate

The nominal ow rate of the heat sink system must be

determined in each operating mode (DHW charging, heat-

ing, cooling mode via separate cooling heat pump buffer

tanks etc.). The ow rate is measured using the installed

ow met er. The measured values can be read off from the

master controller display on the indoor unit.

The ow rate of the heat sink system is adjusted using the

adjusting screw on the heat generator pump (HGP). To

enable correct hydraulic adjustment, in particular during

combined heating or heating/cooling and DHW heating

modes, the appropriate balancing valves must be installed

and the system regulated accordingly.

Make sure that the hydraulic system is lled with

»

water.

Make sure that the system has been fully vented.

»

Make sure that the electrical installation has been

»

carried out and completed professionally.

Material damage

Operating the circulation pumps without water in the system will destroy the pumps.

The power supply to the main power circuit (compressor) must not be switched on until the refrigerant circuit has

been lled with refrigerant and the hydraulic system with

the correct medium.

11. 2 Testing the control circuit

Once all the above conditions have been checked, the power supply to the control circuit (OTE controller, 230 VAC) can be switched on so that the individual functions can be tested.

Check all of the sensors and their values for

»

plausibility.

If the system installer is not present during commissioning or if a fully completed system datasheet is not available, the system is put into operation using the control factory settings. OCHSNER will accept no responsibility for any faulty operation (too low a heating curve, too high a bivalent point, etc.). Any additional work required will be charged to the system installer.

11. 6 Commissioning the system

Before commissioning, the requirements set out in section

11.5 “Necessary conditions for commissioning” must be met.

Commissioning is carried out by OCHSNER Customer Service or by a customer service partner authorised by OCHSNER. The OCHSNER commissioning guidelines apply.

Information

If the system is operated without technically correct commissioning in accordance with the OCHSNER guidelines, all warranty claims will be invalid.

Information

Special work such as system venting, connecting electrical cables, additional training etc., which is not included in OCHSNER‘s scope of delivery, will be invoiced separately.

Activities carried out by OCHSNER:

► Checking that the system has been installed accord-

ing to OCHSNER guidelines. In commissioning the system, OCHSNER offers no warranty regarding the ability to meet the heat demand of the building to be heated.

► Functional testing of the heating circuit (system

pressure, function of diaphragm expansion vessel, quantity settings). Responsibility for the system remains with the system installer.

► Checking ow rates.

► Checking that all shut-off valves are open.

► Checking the electrical connections to the system

components including all required safety devices.

► In the case of air/water and direct evaporation/water

heat pumps (depending on contractual terms):

► Version 1:

Where connecting lines have been laid as contractually agreed by the system installer. OCHSNER Customer Service is responsible for:

- Connecting the previously laid refrigerant lines.

- Conducting leakage tests on the refrigerant lines.

- Emptying the refrigerant lines.

- Insulating the refrigerant lines around the connection points on the indoor and outdoor units.

- Filling the system with the correct refrigerant according to OCHSNER guidelines.

11.7 Decommissioning

You do not need to switch off your heat pump system in the summer. The heat pump control unit changes over automatically between summer and winter.

Material damage

If the power supply to your heat pump system is switched off, frost protection of the system cannot be guaranteed.

You should not switch off the power supply

»

to your heat pump, even outside the heating period.

Should you wish to deactivate your heat pump system, then switch off the system using the master controller. This way, safety functions such as frost protection remain enabled.

Material damage

If the power supply to the heat pump system is interrupted and there is a risk of frost, drain the system on the water side.

Information

OCHSNER Customer Service will provide an explanation of the basic functions of the heat pump system (controller operation, etc.). If the system user is not present on commissioning, the system installer will assume responsibility for this explanation. Instruction on the functionality of the overall system is the responsibility of the system installer.

Check whether the high limit safety cut-out has

»

triggered.

Check the ow rate of the heating water.

»

Remedy the source of the fault.

»

Press the reset button on the rear of the appliance to

»

reset the high limit safety cut-out. The reset button can be reached by hand from the left-hand side.

13. Appliance maintenance

WARNING: Electrocution

For maintenance work, cut off the power supply to the indoor and outdoor units of your heat pump.

Information

Ensure that the refrigerant circuit of your heat pump is tested for leaks once a year (in acc. with Regulation (EU) no. 517/2014).

Ensure year-round access to soldered joints in

»

the refrigerant circuit. Document the results of the leakage test in the

»

system test report.

We recommend arranging for an inspection and if necessary a service on the heat pump to be conducted once a year. We draw your attention to the fact that statutory regulations require regular testing of heating systems by the system user.

The refrigerants used in OCHSNER heat pumps are non-ammable, non-toxic and ozone neutral. Heat pumps are refrigeration equipment and are subject to the provisions of the F-gas Regulations (Regulation (EU) no. 517/2014). OCHSNER Customer Service will be pleased to help in carrying out maintenance and testing, in particular as required by the F-gas Regulations. You can nd more information at www.ochsner.com.

1 Reset button for high limit safety cut-out on rear of

appliance

We recommend testing the heating water system pressure and correcting it if necessary (pressure too high/low).

We recommend adjusting the charge pressure in the diaphragm expansion vessel (DEV) on the system accordingly (system height).

We recommend monitoring the ow rate of the heat sink

system (WNA) and if necessary the heat source system

(WQA) using the ow meters specied by OCHSNER.

We recommend that when non-routine work takes place

requiring relling (e.g. system alteration or pipe breakage),

a current water assessment be prepared and the heat sink

system be relled on the basis of this.

13 .1 Testing safety valve
