NIBE™ F2026Chapter 1 | Important information4

Transport and storage
F2026 must be transported and stored vertically.
Assembly
႑Place F2026 outdoors on a solid level base that can
take the weight, preferably a concrete foundation. If
concrete slabs are used they must rest on asphalt or
shingle.
႑The concrete foundation or slabs must be positioned
so that the lower edge of the evaporator is at the level
of the average local snow depth, although a minimum
of 300 mm.
႑The F2026 should not be positioned next to sensitive
walls, for example, next to a bedroom.
႑Also ensure that the placement does not inconveni-
ence the neighbours.
႑F2026 must not be placed so that recirculation of the
outdoor air can occur. This causes lower output and
impaired efficiency.
႑The evaporator should be sheltered from direct wind.
Place F2026 protected from wind against the evapor-
ator.
႑Large amounts of condensation water as well as melt
water from defrosting can be produced. Condensation
water must be led off to a drain or similar (see page
6).
႑Care must be exercised so that the heat pump is not
scratched during installation.
LEK LEK
PLQ  PP
Do not place F2026 directly on the lawn or other non
solid surface.
If there is a risk of snow slip from roof, a protective roof
or cover must be erected to protect the heat pump, pipes
and wiring.
5Chapter 2 | Delivery and handlingNIBE™ F2026
2 Delivery and handling

Condensation water trough
The condensation water trough is used to collect and
lead away condensation water from the heat pump.
NOTE
It is important to the heat pump function that
condensation water is led away and that the
drain for the condensation water run off is not
positioned so that it may cause damage to the
house.
NOTE
Pipe with heating cable for draining the condens-
ation water trough are not included.
NOTE
To ensure this function the accessory KVR 10
should be used.
NOTE
The electrical installation and wiring must be
carried out under the supervision of an author-
ised electrician.
Caution
If none of the recommended alternatives is used
good lead off of condensation water must be
assured.
႑The condensation water (up to 50 litres/day) collected
in the trough should be routed by pipe to an appro-
priate drain, it is recommended that the shortest
outdoor stretch possible is used.
႑The section of the pipe that can be affected by frost
must be heated by the heating cable to prevent
freezing.
႑Route the pipe downward from F2026.
႑The outlet of the condensation water pipe must be
at a depth that is frost free or alternatively indoors
(with reservation for local ordinances and regulations).
႑Use a water trap for installations where air circulation
may occur in the condensation water pipe.
႑The insulation must be tight against the bottom of
the condensation water trough.

The condensation water can be routed to a drain indoors
(with reservations for local rules and regulations).

General
Pipe installation must be carried out in accordance with
current norms and directives.
F2026 can only operate up to a return temperature of
about 50 °C and an outgoing temperature of about 58 °C
from the heat pump.
F2026 is not equipped with external shut off valves on
the water side; these must be installed to facilitate any
future servicing. The return temperature is limited by the
return line sensor.
Water volumes
When docking with F2026 a minimum available system
volume of at least 20 litres per kW output on the heat
pump is recommended.
NOTE
The pipe work must be flushed before the heat
pump is connected, so that any contaminants
do not damage the components.
Pipe coupling heating medium
circuit
႑F2026 can be connected directly to the heating system
see the section "Docking" or according to one of the
system solutions that can be downloaded from the
website www.nibe.eu.
႑The heat pump must be vented by the upper connec-
tion (XL1, HM-out) using the venting nipple on the
enclosed flexible hose.
႑Install the supplied particle filter (HQ1) before the in-
let, i.e. the lower connection (XL2, HM-in) on F2026.
႑All outdoor pipes must be thermally insulated with at
least 19mm thick pipe insulation.
႑Install shutoff (QM40) and drain (QM1) valves so that
F2026 can be emptied in the event of prolonged
power failures.
႑The supplied flexible hoses act as vibration dampers.
The flexible hoses are fitted so a slight bend is created,
thus acting as vibration damping.
Charge pump
NOTE
The charge pump must be operational, even if
F2026 is not running, to prevent damage due
to freezing.
The charge pump can also be controlled directly from
F2026, terminal (X3), which takes the outdoor temperat-
ure into consideration. Alternatively, the heat pump is
connected to an intermediate circuit with a heat ex-
changer, pump and water with anti-freeze (does not apply
to docking with VVM 300/VVM 500).

Docking alternatives
F2026 can be installed in several different ways. The re-
quisite safety equipment must be installed in accordance
with current regulations for all docked options.
See www.nibe.eu for more docking options.
When docking with F2026 a minimum available system
volume of at least 20 litres per kW output on the heat
pump is recommended.

NOTE
When cable routing, sensor cables and commu-
nication cables must be separated (min 20 cm)
from high voltage cables to prevent interference.
NOTE
Check that you have a VVM 300 with version
1.30 or newer. If you have an earlier model of
VVM 300 the control card must be replaced in
the indoor module. The modular cable is then
connected directly to the outdoor module con-
trol card.
F2026 (slave) can be connected to VVM 300 (master).
F2026 is then controlled by VVM 300 and works with
floating condensing to the heating system and prioritises
hot water charging in VVM 300.
If F2026 cannot meet the heating requirement, additional
heat is shunted in from VVM 300. If the ambient temper-
ature drops below the set stop temperature, VVM 300
engages and takes over heating.

SMO 05 (master) is a simple control module that together
with F2026 (slave), a hot water heater and an extra heat
source create a complete installation.
F2026 works with floating condensing against the heating
system and prioritises hot water charging via the three
