1 Important information
This appliance can be used by children aged from 8
⚠
years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience
and knowledge if they have been given supervision
or instruction concerning use of the appliance in a
safe way and understand the hazards involved.
Cleaning and user maintenance shall not be made by
children without supervision.
Children should be supervised to ensure that they
⚠
do not play with the appliance.
The installation must only be carried out by an
⚠
authorized installer with reference to applicable
rules and orders and these installation instructions.
This apparatus is not intended for persons (including
⚠
children) with reduced physical, sensory or psychological capacity, or who do not have knowledge or
experience, unless supervised or they have received
instructions on how the apparatus functions from a
safety qualified person.
The heat pump must be located in a frost-free envi-
⚠
ronment!
The floor must be able to support the gross weight
⚠
of the heating installation.
The heating installation must be placed on a stable
⚠
surface.
Before the heat pump is supplied with voltage you
⚠
must ensure that the heating system and coolant
system. incl. the heat pump. are filled and bled of
air otherwise the circulation pumps can be damaged.
If the electrician wishes to test his connections
⚠
before the above is carried out this should only
done when it has been checked that the heat
transfer fluid and coolant pumps have been disconnected.
When filling the coolant system the coolant pump
⚠
must be operating but one must ensure that the
compressor and the heat transfer pump cannot
start. The coolant pump can then be run manually
using a separate switch which is located on the
electrical cabinet.
When filling is complete the coolant pump must be
⚠
put in Auto mode.
The appliance is intended to be used by expert or
⚠
trained users in shops, in light industry and on farms
or commercial use by lay persons
⚠
Only spare parts approved by us may be used in this
appliance.
⚠
The power supply must be disconnected during
service and before changing parts in the appliance.
1 .1 Refrigerant
The heat pump’s cooling system (refrigerant circuit) is
filled with R407C or R134a (depending on version) refrigerant.
Work on the refrigerant circuit must only be carried
out by a certified engineer!
Toxicity
In normal use and normal conditions the refrigerant has
low toxicity. However. although the toxicity of the refrigerant is low. it can cause injury (or be highly dangerous) in
abnormal circumstances or where deliberately abused.
The refrigerant vapour is many times heavier than air and
in enclosed spaces. below the level of the door for example. and in the event of leakage. large concentrations can
occur with the risk of suffocation because of lack of oxygen. Spaces in which heavy vapour can collect below the
level of the air must therefore be well ventilated.
Refrigerant exposed to a naked flame creates a poisonous irritating gas. This gas can be detected by
its odour even at concentrations below its permitted
levels. Evacuate the area until it has been sufficiently
ventilated.
Anyone with symptoms of poisoning from the vapour
must immediately move or be moved into the fresh air.
Work on the refrigerant circuit
When repairing the refrigerant circuit. the refrigerant
must not be
destroyed at a special plant. Draining and refilling must
only be carried out using new refrigerant (for the amount
of refrigerant see manufacturer’s plate) through the service valves. All warranties from Danfoss Heat Pump´s AB
are void if. when filling with refrigerant other than R407C
or R134a. it has not been notified in writing that the new
refrigerant is an approved replacement refrigerant
together with other remedies.
Scrapping
When the heat pump is to be scrapped the refrigerant
must be extracted for destruction. The local regulations
for treatment of refrigerant must be followed. See the
relevant Swedish Environmental Protection Agency refrigerant statutes.
released from the heat pump – it must be
1 .2 Noise and vibrations
From the sound and vibration point of view it is important
that the pipe mountings in the ceiling and walls are made
with vibration damping fastenings and that the holes for
lead-ins in the walls are made as large as possible so that
sound and vibration do not spread.
If the house has poor acoustics. special care must be
taken so that the vibrations do not spread into the building.
In such cases no mountings may be made in the house
near the heat pump. All mountings must be in free standing constructions. which themselves are in vibration
damping material such as Solodyn.
In those cases where the coolant side must be mounted
to the building. flexible hoses should be used. although
not the same type as the heat transfer pipes. Flexible
hoses for the heat transfer and hot gas must be
long (600 mm or longer) and connected at 90°. If one
suspects that the floor on which the heat pump is located
may transfer vibration to the rest of the building. the heat
pump must be positioned on Solodyn pads. These pads
must be weight adapted. Always consult the representative from Danfoss Heat pump´s AB in these cases.

ing system, any hot water tanks and the coolant
circuit are filled. Otherwise the pumps can be damaged.
In addition, the following points must be checked before
starting operations:
• Check the rotation direction of the coolant pump. This is
most easily done by setting switch S2 to manual. There
is an indicator lamp, under the cover of the coolant
pump connection terminal box, which lights when the
rotation direction is correct.
• Check that all connections are sealed.
• Check the compressor’s direction of rotation by start-
ing the compressor and feel by hand if the pressure line
(upper pipe) is warm and the suction line (lower pipe) is
cold.
• If this is not the case, two of the phases in the power
supply must be switched (for example L1 and L3).
• Adapt the factory settings to the customer requirements.
