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.

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.

If the house has a cellar the caisson must be positioned

so that it does not affect the house. Otherwise the caisson

can be positioned directly under the heat pump.

The outlet of the condensation water pipe must be at

frost free depth.

Drain indoors

:DWHU VHDO

The condensation water can be routed to a drain indoors

(with reservations for local rules and regulations).

Route the pipe downward from F2026.

The condensation water pipe must have a water trap to

prevent air circulation in the pipe.
