Inspection of the installation
Current regulations require the heating installation to be inspected before it is commissioned. The inspection must
be carried out by a suitably qualified person. Fill in the page for information about installation data in the User
manual.

Transport
JÄSPI Inverter Nordic 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 JÄSPI Inverter Nordic 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 JÄSPI Inverter Nordic 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 JÄSPI Inverter Nordic is lifted with a crane, the
packaging must be untouched.
If a crane vehicle cannot be used the JÄSPI Inverter Nor-
dic can be transported on an extended sack truck.
JÄSPI Inverter Nordic must be taken from its heaviest
side and two people are required to lift JÄSPI Inverter Nor-
dic.
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!

2 Delivery and handling

Assembly
■Place JÄSPI Inverter Nordic 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.
■JÄSPI Inverter Nordic should not be positioned next
to noise sensitive walls, for example, next to a bed-
room.
■Also ensure that the placement does not inconveni-
ence the neighbours.
■JÄSPI Inverter Nordic must not be placed so that recir-
culation 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
JÄSPI Inverter Nordic protected from wind / against
the evaporator.
■A small amount of water may drip from the drainage
hole under JÄSPI Inverter Nordic. Make sure that this
water can run away by selecting a suitable material
underneath JÄSPI Inverter Nordic (see section "Con-
densation").
■Care must be exercised so that the heat pump is not
scratched during installation.

Do not place JÄSPI Inverter Nordic 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.

Installation area
The distance between JÄSPI Inverter Nordic 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 JÄSPI Inverter Nordic must be at least 1,000 mm.
The free space in front must be at least 1,000 mm for any future servicing.

JÄSPI Inverter NordicChapter 2 | Delivery and handling10

Compressor heater
JÄSPI Inverter Nordic is equipped with two compressor
heaters that heat the compressor before start-up and
when the compressor is cold.
The compressor heater (EB10) must have been active for
at least 3 hours before compressor operation can be
initiated. This is done by connecting control voltage.
JÄSPI Inverter Nordic permits compressor start after the
compressor has been warmed up. This can take up to 3
hours.
NOTE
The compressor heater must have been active
for approx. 3 hours before the first start, see
section “Start-up and inspection”.
Condensation
The condensate drain pan collects and leads away the
condensation 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
positioned so that it can cause damage to the
house.
Condensation run-off should be checked regu-
larly, especially during the autumn. Clean if
necessary.
■The condensation water (up to 50 litres/24 hrs) that
collects 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
condensation water trough is not included.
To ensure the function, the accessory KVR 11
should be used.
■Route the pipe downward from the heat pump.
■The 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).
■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
condensation water trough.

If the house has a cellar the stone caisson must be posi-
tioned so that condensation water does not affect the
house. Otherwise the stone caisson can be positioned
directly under the heat pump.
Drain indoors
Water seal
The condensation water is lead to an indoor drain (sub-
ject to local rules and regulations).
When routing pipes indoors, condensation water pipes
must be insulated against condensation.
Route the pipe downward from the heat pump.
The condensation water pipe must have a water seal to
prevent air circulation in the pipe.

General
Pipe installation must be carried out in accordance with
current norms and directives.
The pipe dimension should not be less than the recom-
mended pipe diameter according to the table. However,
each system must be dimensioned individually to man-
age the recommended system flows.
Minimum system flows
The installation must be dimensioned to manage at least
the minimum defrosting flow at 100% pump operation,
see table.

NOTE
An undersized system can result in damage to
the product and lead to malfunctions.
JÄSPI Inverter Nordic can only operate up to a return
temperature of about 55 °C and an outgoing temperat-
ure of about 65 °C from the heat pump.
JÄSPI Inverter Nordic is not equipped with shut-off valves
on the heating medium side, rather these must be in-
stalled to facilitate any future servicing. The return tem-
perature is limited by the return line sensor.
Water volumes
Depending on the size of your JÄSPI Inverter Nordic, an
available water volume is required to prevent short op-
erating times and to enable defrosting. For the optimum
operation of JÄSPI Inverter Nordic, a minimum available
water volume of 10 litres multiplied by the size number
is recommended. E.g. JÄSPI Inverter Nordic-12: 10 litres
x 12 = 120 litres. This applies individually to heating and
cooling systems.
NOTE
The pipe installation must be flushed out be-
fore the heat pump is connected so debris
cannot damage component parts.

ment of the products in relation to each other can
cause self-circulation.
Cascade installations: each heat pump must be fitted
with a non-return valve.
