NOTE
This symbol indicates danger to machine or
person.
Caution
This symbol indicates important information
about what you should observe when main-
taining your installation.
TIP
This symbol indicates tips on how to facilitate
using the product.
Safety precautions
NOTE
■Avoid the use and storage of flammable li-
quids near the climate unit.
■Never install electric equipment that does
not have IPX1 protection (protection against
vertical water drops), under the unit.
The manufacturer assumes no liability, if safety the
standards or protection preventive measures are not
complied with.
Special safety measures
During installation the cooling circuit must be connec-
ted first and then the electrical circuit. Perform in re-
verse order when removing the unit.
During repair
■Disconnect the voltage (via the main switch) before
opening the unit to check or repair the electrical
parts.
■Keep hands and clothing away from moving parts.
■Clean after completing the work, and check that no
metal residue or cable parts have been left inside the
unit.
■Vent the premises during the installation and the
cooling circuit test. Ensure that no refrigerant gas
has leaked out during the installation, as contact with
naked flames or heat sources can be toxic or danger-
ous.
AG-WT10Chapter 1 | Important information2
1 Important information
Read before starting the install-
ation
This heat pump complies with strict safety and function
standards.
It is very important that the installer or the service
technicians install or repair the system so that it works
safely and efficiently.
For a safe installation and good function the
following is required:
■Read this instruction manual carefully before starting
installation.
■Follow the installation and safety instructions exactly
as described and shown.
■Comply with local and national electrical regulations.
■Note all the warning and safety messages indicated
in this manual.
■The unit must be connected to a separate supply.
These instructions are sufficient for installation and
maintenance. If assistance is required for a particular
problem, contact our dealer for further information.
NIBE does not accept any responsibility for damage
that occurs in the event of incorrect installation or im-
proper maintenance.
Electrical requirements
NOTE
The electrical discharge can cause serious
personal injury or death. Only qualified electri-
cians may handle the electrical system.
■Before installation ensure that the mains supply for
the power supply is the same as that indicated on
the climate unit's rating plate.
■Each unit must be connected with approved groun-
ded cable.
■The electrical connections must be performed by a
specially trained and qualified electrician.
■Ensure a ground connection before the unit is
powered.
■Hazardous electrical voltage is used in this electrical
circuit. See electrical wiring diagram and its instruc-
tions below the connection. Incorrect connections
or unsuitable ground connection can cause accidents
or death.
■The yellow/green cable must not be used for connec-
tions other than ground.
■Tighten the cables securely. Incorrect connections
can cause overheating and fire.
■Electrical cables must not come into contact with the
cooling pipes, the compressor or fan's moving parts.
■Use separate cables for each type of cable.
3Chapter 1 | Important informationAG-WT10
Transport
Take care when lifting and moving the indoor and
outdoor unit. We recommend that you ask for assist-
ance and bend your knees when you lift to avoid injur-
ing your back. There is a risk of cutting yourself on the
sharp edges of the climate unit.
Assembly
We recommend that this climate unit be installed by
an authorised technician in accordance with the sup-
plied installation instructions.
NOTE
■Do not install this climate unit where there
are flue gases, flammable gases or a lot of
moisture, e.g. in a greenhouse.
■Do not install this climate unit where there
is equipment that generates too much heat.
■Do not install the unit in premises where it
may be subjected to water splashes (e.g.
laundry rooms).
■To protect the climate unit from corrosion,
the unit must not be installed where it can
be directly exposed to seawater splashes or
sulphur fumes.
Selection of installation location for indoor
unit
Caution
For optimum comfort, energy saving and
function the unit should be positioned as re-
commended below.
Prevent the following:
■Proximity to heat sources that can damage the unit's
cover.
■The presence of oil vapour (such as in a kitchen or
near industrial machinery) because oil contamination
can lead to malfunction or deform surfaces, especially
the unit's plastic surfaces.
■Premises with unstable surfaces can cause vibrations,
noise or water leaks.
■To drill holes in enclosed areas where there are elec-
trical parts or units.
The following is recommended:
■Select the appropriate position from which every
angle of the premises can be heated uniformly.
■Check that the surface is sufficiently stable to carry
the weight of the unit.
■Select a suitable position to ensure good ventilation
and maintenance space around the unit.

2 Delivery and handling
General
Only use refrigerant pipes that are seamless, degreased,
deoxidized and suitable for a pressure of at least 42
bar. The pipes must be supplied with at least 8 mm
vapour-proof insulation.

standard filling
15 mThe refrigerant pipes' total length with
additional filling1
1Additional filling of refrigerant can be done when the unit
runs in cooling operation:
For pipes 1/4" - 3/8" = 15g/m
For pipes 1/4" - 1/2" = 20 g/m
For information about pipe dimensions, see section
"Technical Specifications" on page 18.
Condensation drain
Any condensation removal line must have an internal
diameter of at least 16 mm and be of sufficient length
to transport the condensation to an external drain.
Connecting the cooling circuit
■Use the flare method to connect the pipes.
■Lubricate the contact surfaces and hand tighten, the
tighten the connections using a torque wrench to
obtain a good and secure connection.
■Check carefully that there is no risk of any leakage
prior to the function test.
Caution
For further information, see the installation
manual for the outdoor unit.

mounting and press on the hooks, which are
marked with triangles, for unhooking the panel.
2. The unit can be connected in four directions:
straight back (right and left) - right-hand side - left-
hand side.
3. Assess and mark the holes for the pipes and screws:
the centre point of the holes for the pipes must be
in line with the centre point of the holes for the
lower screws (see the figure for recommended hole
locations).
