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.

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 re-

frigerant leak could accumulate, for example below

ground level (in a dip or low-lying recess), the installa-

tion must satisfy the same requirements that apply

for gas detection and the ventilation of engineering

rooms. Requirements regarding 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 inconveni-

ence 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 section "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.

2 Delivery and handling

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

transported 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 or-

der. Lift by the bottom panel instead of a pallet!
