JÄSPI Inverter Nordic – An excellent
choice
JÄSPI Inverter Nordic is an air/water heat pump, specially designed for the
Nordic climate, which uses the outdoor air as its energy source.
The heat pump is intended for connection to water borne heating systems
and can both heat hot water effectively at high outdoor temperatures
and give a high output to the heating system at low outdoor temperatures.
If the outdoor temperature drops to a level below the stop temperature
all heating must then occur with external additional heat.
Excellent properties for JÄSPI Inverter Nordic:
■Efficient speed-controlled scroll compressor
Efficient speed-controlled scroll compressor that operates at temperat-
ures down to -25 °C.
■Intelligent control
JÄSPI Inverter Nordic connected to intelligent control for optimum
control of the heat pump.
■Fan
JÄSPI Inverter Nordic has automatic capacity regulation of the fan.
■Long service life
The material has been chosen for a long service life and is designed to
withstand the Nordic outdoor conditions.
■Many possibilities
JÄSPI Inverter Nordic is intended for combination with the indoor
module JÄSPI Theowatti Air / control module JÄSPI_MCU40. There is a
wide range of system solutions and accessories for indoor modules and
control modules.
■Silent operation
JÄSPI Inverter Nordic has a silent mode function that allows scheduling
when JÄSPI Inverter Nordic must operate at an even quieter noise level.

2 Installation function
An air/water heat pump installation uses the outdoor air to heat up a
home. The conversion of the outdoor air’s energy into residential heating
occurs in three different circuits. From the outdoor air, (1) , free heat energy
is retrieved and transported to the heat pump. The heat pump increases
the retrieved heat’s low temperature to a high temperature in the refriger-
ant circuit, (2) . The heat is distributed around the building in the heating
medium circuit, (3) .

JÄSPI Inverter NordicChapter 2 | Installation function8

Outdoor air
The outdoor air is sucked into the heat pump.
A
The fan then routes the air to the heat pump’s evaporator. Here,
the air releases the heating energy to the refrigerant and the air's
temperature drops. The cold air is then blown out of the heat
pump.
B
Refrigerant circuit
A gas circulates in a closed system in the heat pump, a refrigerant,
which also passes the evaporator. The refrigerant has a very low
boiling point. In the evaporator the refrigerant receives the heat
energy from the outdoor air and starts to boil.
C
The gas that is produced during boiling is routed into an electrically
powered compressor. When the gas is compressed, the pressure
increases and the gas's temperature increases considerably, from
0 °C to approx 80 °C.
D
From the compressor, gas is forced into a heat exchanger, condens-
er, where it releases heat energy to the indoor module, whereupon
the gas is cooled and condenses to a liquid form again.
E
As the pressure is still high, the refrigerant can pass an expansion
valve, where the pressure drops so that the refrigerant returns to
its original temperature. The refrigerant has now completed a full
cycle. It is routed to the evaporator again and the process is re-
peated.
F
Heat medium circuit
The heat energy that the refrigerant produces in the condenser is
retrieved by the indoor module's water, the heating medium,
which is heated to 55 °C (supply temperature).
G
The heating medium circulates in a closed system and transports
the heated water's heat energy to the house radiators/heating
coils.
H
The indoor module’s integrated charge coil is placed in the boiler
section. The water in the coil heats up the surrounding domestic
hot water.

3 Control of JÄSPI Inverter
Nordic
The heat pump is controlled in various ways, depending on your system.
You control the heat pump via your indoor module JÄSPI Theowatti Air
or control module JÄSPI_MCU40.
See the Installer Manual for the indoor module/control module.
During installation, the installation engineer adjusts the necessary settings
for the heat pump in the indoor module or control module, so that the
heat pump works optimally in your system.

4Maintenance of JÄSPI Inverter
Nordic
Regular checks
When your heat pump is located outdoors some external maintenance is
required.
NOTE
Insufficient maintenance can cause serious damage to JÄSPI Inverter
Nordic, which is not covered by the guarantee.
Checking grilles and bottom panel on JÄSPI Inverter Nordic
Check regularly throughout the year that the grille is not clogged by leaves,
snow or anything else.
You should be particularly vigilant during windy conditions and/or in the
event of snow, as the grille can become blocked.
Also check that the drain holes in the bottom panel are free from dirt and
leaves.
Regularly check that condensation is routed away correctly through the
condensation pipe. Ask your installer for assistance if required.

JÄSPI Inverter NordicChapter 4 | Maintenance of JÄSPI Inverter Nordic12

Cleaning the outer casing
If necessary the outer casing can be cleaned using a damp cloth.
Care must be exercised so that the heat pump is not scratched when
cleaning. Avoid spraying water into the grilles or the sides so that water
penetrates into JÄSPI Inverter Nordic. Prevent JÄSPI Inverter Nordic coming
into contact with alkaline cleaning agents.
In event of long power cuts
In the event of prolonged power failures it is recommended that the part
of the heating system located outdoors is drained. Your installer has in-
stalled a shut off and drain valve to facilitate this. Call and ask your installer
if you are unsure.
Silent mode
The heat pump can be set to "Silent mode", which reduces the heat pump’s
noise level. This function is useful when JÄSPI Inverter Nordic must be
placed in noise-sensitive areas. The function should only be used for limited
periods, because JÄSPI Inverter Nordic might not reach its dimensioned
power.
Updating the software
Information about updating software can be found in the Installer
Manual for your indoor module or control module.

5 Disturbances in comfort
In most cases, the indoor module/control module notes a malfunction (a
malfunction can lead to disturbance in comfort) and indicates this with
alarms and action instructions in the display.
NOTE
Work behind covers secured by screws may only be carried out by, or
under the supervision of, a qualified installation engineer.
Troubleshooting
If the operational interference is not shown in the display the following
tips can be used:
Basic actions
■Group and main fuses of the accommodation.
■The property's earth circuit breaker.
■Make sure that the air flow to JÄSPI Inverter Nordic is not blocked by
foreign objects.
■Check that JÄSPI Inverter Nordic does not have any external damage.
Ice build-up in the fan, grille and/or fan cone
Set the "Fan de-icing" function in the indoor module/control module. For
more information, see the section "Control – Heat pump EB101" in the
Installer Manual.
If problems arise, contact your installer.
Water below JÄSPI Inverter Nordic (larger amount)
■Fit an accessory KVR 11 to divert condensation from the air/water heat
pump.
■Check that the water drainage via the condensation pipe (KVR 11) is
working.
