BA_OCHSNER AIR EAGLE_414_717_V06_EN.docx Page 6 of 76

2.4 Function

Heat is extracted from the outdoor air via the
heat exchanger (evaporator) on the air side. The
refrigerant is evaporated and compressed by a
compressor. This requires electrical energy. The
refrigerant is now at a higher temperature level
and releases the heat from the air to the heating
system via another heat exchanger (condenser).
During this, the refrigerant expands and the
process begins again. At air temperatures below

approx. + 7 °C air humidity condenses as ice on
the evaporator fins. This ice is automatically
removed (defrosting). In the defrost phase, the
fan shuts down and the heat pump circuit is
reversed. The heat required for defrosting is
drawn from the buffer tank or the heating circuit.
At the end of the defrost phase the heat pump
automatically returns to heating mode.

2.5 System overview

The heat pump consists of a split outdoor unit and
an indoor unit which is installed in the boiler room.
The connection to the heating system is made via

the flow and return of the heat sink side of the
heat pump.

3 Outdoor unit

Figure 2: EAGLE outdoor unit

The EAGLE outdoor unit is installed outdoors on a
plinth provided on site. The outdoor unit consists
of a sound-insulated casing for the horizontal fan
and refrigerant circuit components, such as the
evaporator, compressor, expansion valves and
others. It should be installed as closely as possible
to the indoor unit. The minimum clearances to
walls and recesses should be observed for
installation.

CAUTION Risk of injury!

Never remove the grille from the fan.

3.1 Choosing the installation location

The heat pump can be installed at altitudes of up
to 1000 m above sea level.

High wind loads on the outdoor unit can cause
problems with defrosting in defrosting mode.

Avoid installation in an open and exposed location
with high expected wind loads (e.g. flat roof of a
house in a raised location).

Select an installation location where the appliance
is on the side of the building facing away from the
wind (leeward side).

Avoid acoustic reflections when installing the
EAGLE outdoor unit:

• Avoid installation on reverberant floors.

• Installation between two walls can lead to

increased sound levels.

• Avoid installation next to bedrooms.

• Plants and planted areas can reduce sound

levels.

Provide a frost-free drain for any condensate to
drain away. A gravel bed with drainage connection
underneath the evaporator is sufficient. In winter,
ice may form around the drain.

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

• The outdoor unit must be installed at least

1 km away from the sea.

• The installation location selected should

always be on the leeward side of the building
(the side facing away from the sea).

3.5 Foundation for the outdoor unit

A permanent foundation is required beneath the
outdoor unit. The foundation must meet the load
bearing requirements of the outdoor unit (see
section 13, Specification).

• Provide for frost-free drainage (e.g. a gravel

bed with a frost-free connection to a drain)
for condensation that forms on the outdoor
unit.

• Where refrigerant lines are to be laid in the

ground, ensure correct positioning of the
pipe liner when laying the foundations.

• Use rigid underground sewage pipes or

flexible, double-skinned cable ducts (smooth
on the inside) for the pipe liner.

• This must be done in accordance with the

relevant Building Codes of Practice and
regulations.

Take the expected wind loads at the
installation site into consideration.
Ensure that the outdoor unit is
adequately secured to the foundation
to prevent it from tipping over due to
wind loads.

CAUTION: Slipping hazard

If drainage for condensation is
inadequate, ice can build up in winter
in the area around the outdoor unit.

- Ensure drainage for

condensation is sufficient even
at low temperatures.

- Ensure that no ice is formed,

especially around walking
surfaces and entrances around
the outdoor unit.

NOTE

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

occupational safety in your
region.

• Always be aware of the open

edge.

Loads and stresses on roof structure

Note that when outside temperatures are very
low, ice can form beneath the outdoor unit.

In terms of roof structure loads, allow for an ice
load of 400 kg/m² in addition to the dead weight
of the outdoor unit.

When installing the EAGLE outdoor unit on top of
a freestanding car port, a garage or a storage
space, please note the following:

• Provide a suitable plinth for roof installation.

• Take the concentrated load arising from the

dead weight of the outdoor unit (subject to
the type of plinth) and the surface load
caused by possible build-up of ice into
consideration.

• Ensure suitable sound insulation between the

outdoor unit and the installation points on
the plinth.

• Use suitable anti-vibration pads between the

plinth and the outdoor unit legs (OCHSNER
accessory no. 290698) – see Figure 11.

• Provide sound insulation between the

outdoor unit legs and the plinth – see
Figure 11.

CAUTION
Close the valve cap after venting.

Safety valve

NOTE

Water will escape when the safety
valve is opened. Route the drain hose
into the sewage drain at the rear of the
indoor unit. The drain must not be
permanently connected to the sewage
drain! A funnel with a siphon must be
provided.

- Size the drain hose to ensure water can drain

freely when the safety valve is fully open.

- Ensure that the safety valve drain hose is open

to the atmosphere.

- Route the safety valve drain hose with a

continuous slope to the drain.

- Secure the drain hose to prevent movement

when water is running out.

Expansion vessel/system pressure

Preparation for filling:

A 24 l expansion vessel is installed in the heat
pump Golf-Midi indoor unit. In buffer systems or
systems with higher capacity, this expansion
vessel should be checked. If required, install an
additional expansion vessel in the system
(externally, not inside the appliance).

Figure 20: Draining and filling detailed view

Before filling the system, check the pre-charge
pressure in the expansion vessel. This must be
matched to the building height.

- Static head: Difference between highest and

lowest points in the system.

- Pre-charge pressure = static head + 0.3 bar

- System charge pressure = pre-charge pressure

+0.5 bar (when cold)

- Max. permissible operating pressure: 2.6 bar.

Select a safety valve with 3.0 bar.

See EN ISO 4126-1:2013-10-15, part 1: Safety
valves.

- Flush the heating system thoroughly before

filling.

- Only fill with water of potable quality.

Figure 21: T200 hydraulic schematic

The appliance is fitted with a plastic foam outer
casing and a removable front panel. The appliance
is connected hydraulically and electrically to the
heat pump. All hydraulic connections are at the
top.

Further system components are integrated
alongside the DHW tank and the buffer tank:
Heat pump manager, tank charging pump, high
efficiency circulation pump for one direct heating
circuit, multifunctional assembly with safety valve
and 3-way switching valve, emergency/booster
heater for mono energetic operation.

4.2.1.1 DHW tank

The steel tank is fitted internally with a special
direct enamel and a sacrificial anode. The anode
with wear indicator protects the inside of the tank
against corrosion.

The heating water heated by the heat pump is
pumped through an internal indirect coil in the
DHW tank. The internal indirect coil transfers the
absorbed heat to the DHW. The integral heat
pump manager controls DHW heating to the
required temperature.

4.2.1.2 Buffer tank

The steel tank serves to hydraulically separate the
flow rates of the heat pump and the heating
circuit. The heating water heated by the heat
pump is transported to the buffer tank by the tank
charging pump. When there is a demand, the
heating water is supplied to the heating circuit by
the integral heating circuit circulation pump.

4.2.1.3 Heat pump manager (OTE)

The system is controlled via the integral OTE3 heat
pump manager. For adjustment options, see the
controller operating manual.

6 Electrical connection

6.1 Preparation

CAUTION!

Before starting any wiring, isolate the
heating system from the power
supply.

DANGER of electric shock

All electrical connection and
installation work must be carried out
according to the relevant national and
regional regulations.

Connection work may only be carried
out by an approved contractor
according to this manual!

The listed fuse protection ratings and cable cross­sections are guideline values only! The electrician
connecting up the heat pump is responsible for
selecting the correct safety devices. Cables should
be selected by the electrician taking into account
the output and cable lengths.

WARNING

Before commissioning, the necessary
fault protection measures on the

system and the earth connection must be checked
by a certified electrician. The main power circuit

for the compressor motor has no upstream
power contactor on the machine side. Control

devices and equipment to disconnect and shut
down all supply voltages across all poles, which
must be provided on the system side, must meet
the technical safety requirements of EN 60204-1
sections 5 and 13.4.5, as well as the international
regulations in the IEC 60947 series.
During maintenance or service work, shut down all
heat pump supply voltages on the system side and
observe safety regulations to EN 50110-1.
Failure to observe the technical safety
requirements or precautions may result in serious
injury or death.

Checklist:

• The specified voltage must be consistent with

the grid voltage. Pay attention to the
information on the type plate!

• For connection of the appliance, approval

must be obtained from the relevant power
supply utility.

• Fuse protection for the main power circuit

230 V/400 VAC should be provided via a
circuit breaker, which triggers a shutdown
across all poles in the event of a fault.

• If RCDs (FI) are used, they must trigger an

AC/DC-sensitive shutdown.

• The supply lines must be protected against

surges and short circuits.

• It is essential that the regulations of the

responsible PSU (power supply utility) and
the applicable EN standards are observed.

Table 1: Cable selection

6.3 Power connection details

According to the wiring diagram (see section 6.15,
Wiring diagrams) the 400 VAC and 230 VAC power
supplies should be provided separately. The
following power supplies must be provided:

Figure 45: Power supply

A

400 V (230 V) compressor supply

B

PSU signal contact (indoor unit control box)

C

230 V controller supply (indoor unit control
box)

D

400 V (230 V) electric booster heater (indoor
unit control box)

E

Option: 400 V (230 V) DHW auxiliary heater for
anti-legionella function.

The 230 VAC controller power supply to the
outdoor unit is via terminal strip X2 in the indoor
unit control box (L N PE). This ensures that the
outdoor unit and the indoor unit are in phase.

If it is not possible to comply with the
100 mm minimum clearances between
sensor leads and 230 V/400 V, then
screened cables should be used.

The listed fuse protection ratings are guide values
only! The electrician connecting up the heat pump
is responsible for selecting the correct safety
devices.

OCHSNER does not accept liability for faults
resulting from incorrectly designed safety devices!

*PSU = power supply utility

B C D

E

BA_OCHSNER AIR EAGLE_414_717_V06_EN.docx Page 34 of 76

6.4 PSU signal contact

CAUTION!

There is a 230 VAC control voltage
present on the PSU signal contact!

Figure 46: PSU signal contact

Remove the jumper and insert cables as shown in
the drawing. If the PSU signal contact is
interrupted, the compressor and the booster
heater (if installed) will immediately shut down.

6.5 Uninterrupted tariff

In the case of tariff switching without interrupted
power supply, the heat pump is temporarily shut
down by the power supply utility. The PSU signal
contact on the EAGLE indoor unit (terminal
strip X3) should be used for this. To enable the
function, remove the jumper and connect the
cables.

6.6 Shutdown by tariff contactor

In case of shutdown by a tariff contactor (sealed
by the PSU, installed on site), the heat pump
compressor power supply is disconnected. In this
case, the PSU signal contact must be switched via
an auxiliary contact on the tariff contactor
(N/C contact) (otherwise ERROR).

6.7 Night tariff

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

6.8 Modbus wiring

A Modbus connection is required between the
EAGLE outdoor and indoor units. Communication
between the bus subscribers requires a twisted
cable. Cables of type Y(ST)Y 2x2x0.8 mm² have

proved to be suitable.

CAUTION!

Always use a twisted wire pair.

MODBUS = A/B
eBus = SIGNAL/GND

Do not connect GND to the screen!

6.9 Sensor wiring

Never apply voltage to the sensor
terminals! This would destroy the
controller.

The type NTC5K temperature sensors of the OTE
controller are supplied with a cable length of

4.0 m. If this length is not sufficient, the leads can
be extended to the required dimension. Please
use 2x 1.0 mm² flexible cable.

During installation of the sensor cable, ensure that
the cable is not routed parallel to cables with
AC voltage >230 VAC.

Outdoor sensor TA

Install the outdoor sensor of the controller at a
height of approx. 2.5 m on the outside of the
building wall (facing north-west). Make sure that
the outdoor sensor is not exposed to direct
sunlight or wind, as this will impair the control
characteristics. Also avoid positioning it close to
the evaporator. There may be a risk of influence
on the control.

Mixer sensor TMK

If a mixer circuit is installed in addition to the
direct heating circuit, a mixer sensor must be
installed. The mixer sensor is a contact sensor and
is supplied with the heat pump including a band
clamp and heat conducting paste. Install the mixer
sensor directly downstream of the mixer circuit
pump. When using multi-skin or plastic pipes,
provide a suitable large metal bridge.

Remove jumper

230 VAC

BA_OCHSNER AIR EAGLE_414_717_V06_EN.docx Page 35 of 76

Buffer sensor (TPO, TPM)

Two buffer sensors are required in the buffer tank.
The heat pump is switched on based on readings
from the TPO and switched off based on those
from the TPM.

- Install a sensor pocket in the female socket

provided for the upper buffer sensor (TPO)

- Install a sensor pocket in the female socket

provided for the lower buffer sensor (TPM)

NOTE

In systems with direct heating circuit,
install the TPO sensor in the heating
flow of the heat pump indoor unit.

- Install the TPO sensor in the indoor

unit at the marked location on the
heating flow pipe, downstream
from the electric booster heater
(MFA).

- The required controller parameters

are set by OCHSNER customer
service or specialist personnel
authorised by OCHSNER.

In systems with a buffer tank, a bypass
or a low loss header or a heating
circuit with mixing valve, the TPO
sensor must not be installed in the
indoor unit.

Figure 47: Pipe marking in the heat pump indoor unit

DHW sensor TB

The DHW sensor is included in the delivery of the
heat pump. OCHSNER DHW tanks are fitted with
appropriate female sockets for installing the
sensor.

Install the DHW sensor in the top one-third of the
DHW tank (or at the very least in the top half). The
lower the selected location of the DHW sensor,

the larger the switching hysteresis (5-15 K) will
need to be.

NOTE

Ensure that the DHW sensor is correctly
positioned and extends beyond the
tank insulation into the interior of the
DHW tank. This is the only way in which
the temperature can be measured
correctly.

6.10 Pumps, drives 230 VAC

Pumps (heating circuit pumps, DHW charging
pump) and drives (mixer valves, etc.) are
connected directly to the controller.

A test run may only be carried out on a system that
has been prepared for commissioning! A relay test
can be performed on the OTE controller to check
the relevant outputs (actuators).

6.11 HLSC on the heating circuit

If an on-site high limit safety cut-out (HLSC) is
installed, it can be connected to the HLSC contact
on terminal strip X3. This shuts down the feed
pump. This only applies for hydraulic connection
versions 7.1 and 7.2. In all other versions, the HLSC
must be installed directly in the power supply of
the on-site heating circuit pump.

6.12 DHW booster heater

A separate contactor must be provided in the
electric distribution box for the optional electric
auxiliary heater in the DHW tank (anti-legionella
function). See electrical wiring diagram in section
13, Specification. This function is an option and
therefore not supplied with the heat pump.

7 Heating system

The heating water and system pressure should be
checked regularly by the system operator and
corrected in case of deviations (pressure too
high/low). The flow rates at the heat sink system
(WNA) are monitored by the integral flow sensor.
The specified system maintenance intervals and
system checks must also be observed.

If major modifications or pipe breakages require
draining and subsequent replacing of a large
proportion of the heating water, this should be
done in the presence of OCHSNER customer
service or by an authorised OCHSNER authorised
partner (see enclosed logbook). In the case of non­routine refilling (e.g. after modifications or pipe
breakages), a current water assessment must be
prepared, and, on the basis of this, the heat sink
system must be refilled, with additives if required,
by the installer.

7.1 Quality of heating water

Use the correct fill water that is suitable for the
components of your heating system. We
recommend fill water prepared according to
Guideline VDI 2035-2.

A high pH value and low electrical conductivity in
the fill 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 (calcification).

Fill water characteristics

pH value at 25°C

8.5-10

Electrical conductivity at
25°C

< 100 μS/cm
Oxygen content

< 0.05 mg/l

Chloride

< 30 mg/l

Unsuitable fill water can damage your
system due to scaling and corrosion. If

necessary, ensure that the fill water is
professionally softened and
demineralised.

7.2 Pressure maintaining system

For the operational reliability of your
system in defrosting or cooling mode, it
is important that the hydraulic safety
and pressure maintaining devices are
sufficiently sized and inspected annually
according to the relevant standards.

CAUTION

The closures provided are only for

transport. Replace them with suitable

plugs if the DHW flow or return is not
being used!

BA_OCHSNER AIR EAGLE_414_717_V06_EN.docx Page 46 of 76

8 Commissioning

8.1 Before starting

The heat pump has no separate ON/OFF switch. In
an emergency, the system must be shut down via
the specified circuit breaker. The circuit breaker
must be accessible so that an emergency
shutdown can be performed at any time.

Caution - risk to life

First-time start-up of electrical systems
is permitted only in the presence of a

qualified electrician.

Do not turn ON (or OFF) the power to the system,
until:

• Nobody can be put at risk

• All installation work on the heat pump is

completed

• All wiring is completed

• Voltages have been checked according to

the documentation

• The hydraulic system has been filled with

water

• The system has been fully vented

The supply voltage for the compressor must not
be turned on, until the refrigerant circuit and the
hydraulics have been filled with the correct
medium.

Once all conditions above have been checked and
met, the controller voltage of 230 VAC (fuse F1)
can be switched on for checking individual
functions.

Carefully check all sensors and their measurement
values for plausibility and all outputs used in your
hydraulic system for correct function.

CAUTION

Operating the heat pump with too little
or no refrigerant will damage the
appliance. Operating circulation
pumps without water in the system will
destroy the pump.

The heat pump must be commissioned by
OCHSNER customer service or an authorised
OCHSNER partner. The OCHSNER commissioning
guidelines apply. Operating the system without it
having been properly commissioned by factory
customer service will void all guarantee and
warranty rights.

8.2 Persons required on site

The electrician, installer and future system
maintainer or operator must be present during
commissioning for instruction.

Information for the system installer:

• The OCHSNER customer service engineer /

customer service partner makes the user
specific adjustments according to the
information in the system datasheet. 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 liability for
any faulty operation (heating curve too low,
bivalent point too high, etc.). Any claims
resulting from this will be charged to the
system installer.

• For the system to operate efficiently, it is

essential that hydraulic balancing is carried
out and the controller is adjusted according to
the system requirements.

• Special work, such as venting, electrical

connections, renewed instruction, etc., not
included in the scope of work provided by
OCHSNER will be charged separately.

BA_OCHSNER AIR EAGLE_414_717_V06_EN.docx Page 47 of 76

8.3 Setting the flow rate

The nominal flow rate must be ensured in each
operating mode (DHW charging, heating or
cooling mode via separate cooling/buffer tank,
etc.). The flow rate is measured via the installed
flow sensor and shown on the OTE controller
display. On the supplied circulation pumps, the
flow rate is adjusted via the adjusting screw.

To enable hydronic balancing according to the
relevant standards, in particular during combined
heating or heating/cooling and DHW heating
modes, the appropriate balancing valves must be
installed and the system regulated accordingly.

The measured flow rate is displayed on the heat
pump display and must correspond to the nominal
flow rate.

9.2 Appliance function

Heating circuit

The heating circuits operate fully automatically
with weather compensation and summer/winter
changeover.

DHW

DHW heating is according to the default target
value. The efficiency of the system can be
increased with a DHW time program.

Anti-legionella function

To prevent legionella, the DHW has to be
periodically heated to a temperature of at least
60°C. The anti-legionella function is automatic and
can be controlled via a time program. Depending
on the system version, the electric booster heater
is activated.

Second heat generator

OCHNSER AIR EAGLE heat pumps are supplied
with an electric emergency/booster heater as
standard. The electric immersion heater is built
into the MFA module and is required to ensure the
operational reliability of your heating system.
Protect the supply voltage in the main distribution
box across all poles. The voltage is supplied via the
KM3 contactor and is automatically switched on
by the system.

Effect of the electric emergency/booster heater
in the heat pump flow:

• Mono energetic operation

The electric emergency/booster heater
guarantees heating mode and the provision of
high DHW temperatures when the bivalent
point is not reached.

• Emergency mode

Should the heat pump fail due to a fault, the
heating output is provided by the electric
emergency/booster heater.

For the operational reliability of your heating
system, ensure the power supply to the electric
booster heater at all times!

Screed drying program

In case of return temperatures <25°C (room
temperatures) the heat for drying has to be
provided by the electric emergency/booster
heater! At these low system temperatures the
heat for drying must not be provided by the heat
pump as the frost protection of the appliance can
no longer be guaranteed during the defrost cycle.
At the end of the drying out program, the electric
emergency/booster heater can be disconnected
as long as it is not required for the operation of the
appliance. Note that emergency operation is not
possible in the screed drying program.

9.3 System operation

Running costs

Depending on the residual building moisture,
increased running costs of up to 50% are to be
expected.

Flow temperatures

To ensure energy saving operation of the heat
pump, try to keep the heating flow temperature
(and also DHW temperatures) as low as possible.
For EAGLE heat pumps, the max. system
temperature should be limited to 60°C.

NOTE

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

10.2 Dealing with faults

Various Faults "Er. XXX" as well as troubleshooting
options are displayed on the OTE controller. In the
event of a fault, your installer is your first point of
contact. The installer must be notified of the faults
and can provide you with valuable information for
troubleshooting. Your installer knows your
hydraulic system and how it operates. The causes
of faults can be found in the settings or hydraulics.

If it is nevertheless not possible to identify or
rectify the causes, OCHSNER customer service is
available to help.

10.3 Rectifying minor causes
independently

Your heat pump is extremely maintenance
friendly. To operate the heat pump efficiently and
without faults, you can remedy minor causes
simply on site.

Before you start:

• Disconnect the system from the power supply,

• Safeguard against unauthorised reconnection,

• Ensure it is voltage-free,

• Before carrying out any further work, wait at

least 4 minutes after switching off the power
supply!

• Do not reach into the fan!

• Do not remove the protective grille from the

fan.

Ensure that:

• the evaporator is free from leaves and twigs or

other foreign bodies.

• condensate can drain away.

• there is sufficient water in the heating circuit.

• the system pressure is adequate.

You can optimise your system by checking the
heating circuit and DHW heating settings. Keep
records and only adjust 1-2 settings in a day.

10.4 Cleaning and care

Protect the appliance from dust and dirt during
building work. A large plastic bag is provided for
this purpose. A damp cloth is sufficient to look
after plastic and sheet metal parts. Do not use any
abrasive or corrosive cleaning materials.

Ensure that no ice is formed, especially around
walking surfaces and entrances around the
outdoor unit.

BA_OCHSNER AIR EAGLE_414_717_V06_EN.docx Page 53 of 76

11 Maintenance

For maintenance work, disconnect the
power supply to the indoor unit and
the outdoor unit of your heat pump.

NOTE

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-flammable, non-toxic and ozone neutral.
However, 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. For

more information, see www.ochsner.com.

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

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

We recommend monitoring the flow rate of the
heat sink system (WNA) and if necessary the heat
source system (WQA) using the flow meters
specified by OCHSNER.

We recommend that when non-routine work
takes place requiring refilling (e.g. system
alteration or pipe breakage), a current water
assessment be prepared and the heat sink system
be refilled on the basis of this.

11.1 Customer service

Once a date has been agreed with or requested
from OCHSNER customer service, repairs to your
heat pump are carried out by a trained customer
service specialist on site. In order for service work
to be carried out, the accessibility of the heat
pump and auxiliary equipment must be ensured at
all times!

Please observe the minimum
clearances when installing the
equipment.

12 Environment and recycling

12.1 Disposal of transport packaging

The transport packaging for the heat pump
consists of recyclable raw materials. Waste
transport packaging should be sorted and
recycled. Leave disposal of transport packaging to
the authorised contractor who has installed the
appliance.

12.2 Decommissioning

Before decommissioning, all 'live'
connections should be isolated from
the power supply by an authorised
contractor.

Appliances with refrigerant should only be
decommissioned by an authorised contractor
(refrigeration/air conditioning/heating). The
refrigerant should be emptied/removed and
recycled or disposed of by the contractor.

Improper disposal of refrigerant can
cause significant environmental
damage and carries a penalty!

12.3 Disposal of the appliance

The old heat pump should be disposed
of at regional waste collection facilities
in accordance with applicable regional

environmental regulations and standards.

Parts of the heat pump must not be disposed
of as domestic waste!
