This symbol indicates important information
about what you should consider when in-
stalling or servicing the installation.
TIP
This symbol indicates tips on how to facilitate
using the product.
Safety precautions
Caution
Install the system in full accordance with this installation
manual.
Incorrect installation can cause bursts, personal injury, water leaks,
refrigerant leaks, electric shocks and fire.
Pay attention to the measurement values before working on
the cooling system, especially when servicing in small rooms,
so that the limit for the refrigerant’s concentration is not ex-
ceeded.
Consult an expert to interpret the measurement values. If the refri-
gerant concentration exceeds the limit, there may be a shortage
of oxygen in the event of any leak, which can cause serious injury.
Use original accessories and the stated components for the
installation.
If parts other than those stated by us are used, water leaks, electric
shocks, fire and personal injury may occur as the unit may not work
properly.
Ventilate the working area well – refrigerant leakage may occur
during service work.
If the refrigerant comes into contact with naked flames, poisonous
gas is created.
Install the unit in a location with good support.
Unsuitable installation locations can cause the unit to fall and cause
material damage and personal injury. Installation without sufficient
support can also cause vibrations and noise.
Ensure that the unit is stable when installed, so that it can
withstand earthquakes and strong winds.
Unsuitable installation locations can cause the unit to fall and cause
material damage and personal injury.
The electrical installation must be carried out by a qualified
electrician and the system must be connected as a separate
circuit.
Power supply with insufficient capacity and incorrect function can
cause electric shocks and fire.
Use the stated cables for the electrical connection, tighten the
cables securely in the terminal blocks and relieve the wiring
correctly to prevent overloading the terminal blocks.
Loose connections or cable mountings can cause abnormal heat
production or fire.
Check, after completed installation or service, that no refriger-
ant leaks from the system in gas form.
If refrigerant gas leaks into the house and comes into contact with
an aerotemp, an oven or other hot surface, poisonous gases are
produced.
Use types of pipe and tools stated for this type of refrigerant.
Using existing parts for other refrigerants can cause breakdowns
and serious accidents due to process circuit bursts.
Switch off the compressor before opening/breaching the refri-
gerant circuit.
If the refrigerant circuit is breached /opened whilst the compressor
is running, air can enter the process circuit. This can cause unusually
high pressure in the process circuit, which can cause bursts and
personal injury.
Switch off the power supply in the event of a service or inspec-
tion.
If the power supply is not shut off, there is a risk of electric shocks
and damage due to the rotating fan.
Do not run the unit with removed panels or protection.
Touching rotating equipment, hot surfaces or high voltage parts
can cause personal injury due to entrapment, burns or electric
shocks.
Cut the power before starting electrical work.
Failure to cut the power can cause electric shocks, damage and in-
correct function of the equipment.
Care
Carry out the electrical installation with care.
Do not connect the ground lead to the gas line, water line, lightning
conductor or telephone line's ground lead. Incorrect grounding
can cause unit faults such as electric shocks due to short-circuiting.
Use main switch with sufficient breaking capacity.
If the switch does not have sufficient breaking capacity, malfunc-
tions and fire can occur.
GreenMaster-HPChapter 1 | Important information4
1 Important information

Always use a fuse with the correct rating in the locations where
fuses are to be used.
Connecting the unit with copper wire or other metal thread can
cause unit breakdown and fire.
Cables must be routed so that they are not damaged by metal
edges or trapped by panels.
Incorrect installation can cause electric shocks, heat generation
and fire.
Do not install the unit in close proximity to locations where
leakage of combustible gases can occur.
If leaking gases collect around the unit, fire may occur.
Do not install the unit where corrosive gas (for example nitrous
fumes) or combustible gas or steam (for example thinner and
petroleum gases) can build up or collect, or where volatile
combustible substances are handled.
Corrosive gas can cause corrosion to the heat exchanger, breaks
in plastic parts etc. and combustible gas or steam can cause fire.
Do not use the unit for specialist purposes such as for storing
food, cooling precision instruments, freeze-conservation of
animals, plants or art.
This can damage the items.
Do not install and use the system close to equipment that
generates electromagnetic fields or high frequency harmonics.
Equipment such as inverters, standby sets, medical high frequency
equipment and telecommunications equipment can affect the unit
and cause malfunctions and breakdowns. The unit can also affect
medical equipment and telecommunications equipment, so that
it functions incorrectly or not at all.
Take care when carrying the unit by hand.
All parts of the unit weigh more than 20 kg and must be carried
by at least two people. Wear safety gloves to minimise the risk of
cuts.
Dispose of any packaging material correctly.
Any remaining packaging material can cause personal injury as it
may contain nails and wood.
Do not touch any buttons with wet hands.
This can cause electric shocks.
Do not touch any refrigerant pipes with your hands when the
system is in operation.
During operation the pipes become extremely hot or extremely
cold, depending on the method of operation. This can cause burn
injuries or frost injuries.
Do not shut off the power supply immediately after operation
has start.
Wait at least 5 minutes, otherwise there is a risk of water leakage
or breakdown.
Do not control the system with the main switch.
This can cause fire or water leakage. In addition, the fan can start
unexpectedly, which can cause personal injury.
Especially for units intended for R407C and R410A
- Do not use other refrigerants that those intended for the unit.
- Do not use charging bottles. These types of bottles change the
composition of the refrigerant, which makes the performance of
the system worse.
- When filling refrigerant, the refrigerant must always leave the
bottle in liquid form.
- R410A means that the pressure is about 1.6 times as high as for
conventional refrigerants.
- The filling connections on units with R410A are different sizes, to
prevent the system being filled with the incorrect refrigerant by
mistake.
Recovery
Leave the disposal of the packaging to the in-
staller who installed the product or to special
waste stations.
Do not dispose of used products with normal household
waste. It must be disposed of at a special waste station
or dealer who provides this type of service.
Improper disposal of the product by the user results in
administrative penalties in accordance with current legis-
lation.
Environmental information
F-Gas Regulation (EU) No. 517/2014
This unit contains a fluorinated greenhouse gas that is
covered by the Kyoto agreement.
The equipment contains R407C and R410A, fluorinated
greenhouse gases with GWP values (Global Warming
Potential) of 1774 and 2088 respectively. Do not release
R407C or R410A into the atmosphere.

Transport and storage
GreenMaster-HP comes complete in assembled version
with a base frame permanently installed under the heat
pump section. On request, the unit can be supplied
without the liquid filled to allow easy dismantling and
reinstallation in properties where the transport route is
narrow, or where it is not possible to make holes to lift
in the unit. For further details, see under Separable ver-
sion due to narrow transport routes.
Loading, unloading and transport on site are managed
using forklift trucks, pallet trucks or cranes. Suitable lift-
ing straps must always be used.
The unit should be transported in the upright position
or at an incline of less than 30°.
Unloading and lifting with forklift truck or
pallet truck
The truck’s forks must be long enough to ensure there
is no risk of the unit’s underside being damaged. Make
sure that the forks reach through to the other side of
the unit.
Unloading and lifting with crane
If the unit comes on a pallet, it must be lifted off using
straps.
A unit that comes with the machine feet already fitted
has to be lifted with the straps on the inside of the ma-
chine feet and with the straps securely tightened.
A unit that come without machine feet has to be lifted
using flat beams and with the straps securely tightened.
The lifting beams have to be positioned so there is no
risk of the unit falling. Ensure that the beams are strong
enough to lift the load, and that the straps are not in
contact with and damaging the unit’s upper section. Use
beams or a lifting yoke to keep the straps away from the
unit’s upper section.
Storage before installation
The unit must be protected against the weather and
impacts. The packaging must be removed and the unit
covered with a tarpaulin or similar. To ensure that there
is as little condensation as possible, good circulation
must be guaranteed between the protective cover and
the unit.
Separable version due to narrow transport
routes
If the unit is to be moved into a fan room in properties
where the transport route is narrow, or where it is not
possible to make holes to allow lifting in, the unit can
be supplied without the refrigerant. This means that the
unit can be split into six parts and a base frame.
To split up the unit, read and follow the instructions un-
der Dismantling and assembly on page 9.
The weight of each part can be found in the relevant
unit specification for the installed unit.
Assembly
The surface below the unit has to be flat enough so the
unit’s final position is, and will remain, completely hori-
zontal. Using the machine feet, the frame can be adjus-
ted so the unit attains a horizontal position. The surface
must withstand the load from the unit. If the installation
uses lightweight structures or has especially sensitive
areas, the unit should be placed on a vibration-absorbing
base with the necessary properties.
Caution
Ducts must be insulated against vibrations and
noise, and must not be mounted directly on
beams, beam joints or other critical building
components.
Set-up for outdoor installation
The unit has no drip mouldings between unit and under-
carriage. A local fitter must install additional protection
and insulation for the frame, to ensure that water does
not run down under the unit. NIBE AirSite design as-
sumes that the unit is installed on a sealed roof, which
is not at risk of moisture damage due to drainage from
the condensate drip tray or external moisture such as
rain or snow.
GreenMaster-HPChapter 2 | Delivery and handling8
2 Delivery and handling

NOTE
Water seals placed outdoors must be protected
with heating cable (accessory set; electric
heating coil) to prevent freezing when it is cold
outdoors.
Installation area
A free space of at least 950 mm in front of the unit is
recommended. In order to make maintenance and in-
spection easier, this space should preferably be as large

GreenMaster-HPChapter 3 | Design of the exhaust air heat pump18

General
Pipe and ventilation installation has to be performed
according to applicable regulations.
GreenMaster-HP can operate with a return temperature
of up to approx. 58 °C and an outgoing temperature of
65 °C.
GreenMaster-HP is not equipped with external shut off
valves; these should be installed to facilitate any future
servicing. In addition, non-return valves and particle fil-
ters should be installed.
GreenMaster-HP when placed indoors, is equipped with
sheet metal guide connections for exhaust air and extract
air ducts. When located outdoors, GreenMaster-HP is
equipped with sheet metal guide connection for exhaust
air duct and ventilation grille on the extract air side.
Rectangular duct connections are standard on all models
of GreenMaster-HP. Connection dimensions for guide
connections can be found in the relevant unit specifica-
tion for the installed unit.
NOTE
The pipe systems have to be flushed clean be-
fore GreenMaster-HP is connected, to prevent
any contaminants from damaging the compon-
ents.
NOTE
Do not solder directly on the pipes in GreenMas-
ter-HP, because of internal sensors.
Compression ring coupling alternatively pres-
sure connection should be used.
NOTE
The heating system's pipes must be earthed to
prevent a potential difference between them
and the building's protective earth.
NOTE
The potential to clean the air ducts in the future
is required.
Ventilation flow
The ventilation flow must comply with the applicable
national standards.
Connect the property’s common exhaust air duct with
the guide connection to the unit’s filter side.
If flue gas extraction is required, an extra air duct with a
bypass damper has to be installed and connected to the
unit’s prepared fan-in-operation connection.
Adjusting ventilation
In order to achieve the necessary air exchange in the
property, the correct adjustment of the air flow in the
air treatment unit is required.
As soon as possible after installation, the ventilation
should be adjusted to ensure the air flow is set according
to the planned value for the property. Incorrect adjust-
ment can result in impaired function, recovery and
comfort.
System diagram
GreenMaster-HP consists of two cooling modules, circu-
lation pumps, air treatment unit, brine circuit and control
system, with the option for additional heat. GreenMaster-
HP is connected to the property’s heating medium circuit.
