Important information

Inspection of the installation

Current regulations require the heating installation to undergo an installation inspection before it is commissioned. The

inspection must be carried out by a suitably qualified person. In addition, fill in the page for information regarding the in-

stallation data in the User Manual.

Transport

S2125 must be transported and stored vertically.

NOTE

Ensure that the heat pump cannot fall over during

transport.

Check that the heat pump has not been damaged during

transport.

LIFT FROM THE STREET TO THE SET UP

LOCATION

If the base allows, the simplest thing is to use a pallet truck

to move the S2125 to the set up location.

NOTE

The centre of gravity is offset to one side (see print

on the packaging).

LEK

C:a 180 kg

Approx. 180 kg

If S2125 needs to be transported across soft ground, such

as a lawn, we recommend using a crane truck that can lift

it to the installation location. When S2125 is lifted with a

crane, the packaging must be untouched.

If a crane vehicle cannot be used the S2125 can be transpor-

ted on an extended sack truck. S2125 must be taken from

its heaviest side and two people are required to lift S2125.

LIFT FROM THE PALLET TO FINAL POSITIONING

Before lifting remove the packaging and the securing strap

to the pallet.

Place lifting straps around each machine foot. Lifting from

the pallet to the base requires four persons, one for each

lifting strap.

SCRAPPING

When scrapping, the product is removed in reverse order.

Lift by the bottom panel instead of a pallet!

Delivery and handling

Assembly

•Place the heat pump in a suitable location outdoors to

prevent any risk of the refrigerant flowing in through

ventilation openings, doors or similar openings in the event

of a leak. It must also not constitute a hazard to people or

property in any other way.

•If the heat pump is placed in a location where any refriger-

ant leak could accumulate, for example below ground level

(in a dip or low-lying recess), the installation must satisfy

the same requirements that apply for gas detection and

the ventilation of engineering rooms. Requirements regard-

ing sources of ignition must be applied where appropriate.

•Place S2125 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.

•The lower edge of the evaporator must not be lower than

the level of the average local snow depth. The base should

be at least 70 mm tall.

•S2125 should not be positioned next to noise sensitive

walls, for example, next to a bedroom.

•Also ensure that the placement does not inconvenience

the neighbours.

•S2125 must not be placed so that recirculation of the

outdoor air is possible. Recirculation entails reduced power

and impaired efficiency.

•The evaporator must be sheltered from direct wind / ,

which negatively affects the defrosting function. Place

S2125 protected from wind / against the evaporator.

•A small amount of water may drip from the drainage hole

under S2125. Make sure that the water can run away by

selecting a suitable material underneath S2125 (see sec-

tion "Condensation").

•Care must be exercised so that the heat pump is not

scratched during installation.

Do not place S2125 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.

NIBE S2125Chapter 2 | Delivery and handling8

INSTALLATION AREA

The distance between S2125 and the house wall must be at least 350 mm, but not more than 500 mm in locations that are

exposed to the wind. The free space above S2125 must be at least 1,000 mm. The free space in front must be at least

1,000 mm for any future servicing.

Condensation

The condensate drain pan collects and leads away the con-

densation water.

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 posi-

tioned so that it can cause damage to the house.

Condensation run-off should be checked regularly,

especially during the autumn. Clean if necessary.

•The condensation water (up to 50 litres/24 hrs) that col-

lects in the trough should be routed away by a pipe to an

appropriate drain, it is recommended that the shortest

outdoor stretch possible is used.

•The section of the pipe that can be affected by frost must

be heated by the heating cable to prevent freezing.

TIP

Pipe with heating cable for draining the condens-

ation water trough is not included.

To ensure the function, the accessory KVR 11

should be used.

•Route the pipe downward from S2125.

•The outlet of the condensation water pipe must be at frost

free depth.

•Use a water trap for installations where air circulation may

occur in the condensation water pipe.

•The insulation must seal against the bottom of the con-

densation water trough.

good lead off of condensation water must be as-

sured.
