2 Important information/Safety instructions
2.1 General safety precautions
Warning This appliance can be used by children aged 8 years and above, and
by persons with reduced physical, sensory or mental capabilities or
lack of experience or knowledge, provided that they are supervised or
have been instructed in the safe use of the appliance and understand
the hazards involved. Children must not clean or carry out user maintenance on the appliance except under adult supervision.
Warning Ensure that children do not play with the product.
Warning The installation must only be carried out by a qualified installation en-
gineer, following applicable rules and regulations in addition to these
installation instructions.
Caution The heat pump must be located in a frost-free environment!
Caution Installation and connection should be carried out in accordance with
the instructions, in order to avoid subjecting local residents to noise
disturbance.
Caution The heating appliance should be placed on a stable surface that can
support the gross weight of the heating appliance.
Caution Before the heat pump is powered, you must ensure that the heating
system and coolant system, including the heat pump, are filled and
bled; otherwise, their circulation pumps may be damaged.
Caution If the electrician wishes to test the electrical connections before the
above is carried out, this should only be done after ensuring that the
heat transfer fluid pump and coolant pump are disconnected.

Caution When filling the coolant system the coolant pump must be operating;
you must ensure that the compressor and the heat transfer pump cannot start.
Caution This appliance is intended for use by expert or trained users in shops,
in light industry and on farms, or for commercial use by lay people.
Caution In accordance with EN60335-2-40, this product is classified as "not
available to the general public." This means that the product is designed to be handled by trained staff and installed in an engine room
or similar.
Caution Isolate the power supply to the heat pump while servicing the appli-
ance or replacing parts.
Caution Only spare parts approved by Danfoss Värmepumpar may be used for
this appliance.
N
In normal operation the heat pump generates noise and vibrations.
The appliance should be set up and connected in accordance with the
instructions in order to avoid noise being spread to noise-sensitive
areas.
2.2 Refrigerant
2.2.1 Refrigerant
Caution Work on the refrigerant circuit must only be carried out by a certified
refrigeration engineer.
Although the heat pump's refrigerant circuit is filled with a chlorine-free and environmentally-approved refrigerant that will not affect
the ozone layer, work on this system may only be carried out by authorised persons.
The refrigerant circuit is hermetically sealed and is subject to the EC regulation 517/201. According to EC regulation 517/2014, for heat
pumps containing 10 tonnes of CO2 equivalent or more, with hermetically sealed fluorinated greenhouse gases, an annual inspection of
leakage must be carried out by qualified personnel.

2.2.2 Fire risk
The refrigerant is not combustible or explosive in normal conditions.
2.2.3 Toxicity
In normal use and normal conditions the refrigerant has low toxicity. Even though the toxicity of the refrigerant is low, it can cause injury
(or even death) in abnormal circumstances or if deliberately abused.
Warning Risk of personal injury! Spaces in which heavy vapor can collect below
the level of the air must be well ventilated.
Refrigerant vapour is heavier than air, and in enclosed spaces or in areas below the level of the door, for example, seepage can give rise
to high concentrations with a resultant risk of suffocation due to lack of oxygen.
Warning Risk of personal injury! Refrigerant exposed to a naked flame creates a
poisonous irritating gas. This gas can be detected by its odor even at
concentrations below its permitted levels. Evacuate the area until it
has been sufficiently ventilated.
2.2.4 Working on the refrigerant circuit
Caution When the refrigerant circuit is repaired, the refrigerant must not be re-
leased from the heat pump - it must handled appropriately.
Draining and refilling must only be carried out using new refrigerant (for the amount and type of refrigerant see manufacturer's plate)
through the service valves.
Caution All warranties will become void if a refrigerant, other than what Dan-
foss specifies, is used for refilling.
2.2.5 Scrapping
Caution When the heat pump is to be scrapped the refrigerant must be extrac-
ted for disposal. Local rules and regulations related to the disposal of
refrigerant must be followed.

2.3 Electrical connection
Warning Hazardous electrical voltage! The terminal blocks are live and can
cause death through electric shock. All power supplies must be isolated before electrical installation is started. The heat pump is connected internally at the factory, for this reason electrical installation consists primarily of the connection of the power supply.
Caution Electrical installation may only be carried out by an authorized electri-
cian and must follow applicable local and national regulations.
Caution The electrical installation must be carried out using permanently rout-
ed cables and must follow applicable local and national regulations. It
must be possible to isolate the power supply using an all-pole circuit
breaker with a minimum contact gap of 3 mm.
2.4 Water quality
This heat pump and its components is developed to reliable and efficient work with water qualities in line with VDI 2035. In practice this
means that some general precautions should be taken:
As a heating system often contains small amounts of suspended solids (rust) and sludge products from calcium oxide, precaution should
be taken to ensure that the water in the heating system is as clean as possible to ensure long lasting performance and minimize the risk
of reliability issues. If magnetite can be expected in the heating system, cleaning of system and /or installation of magnetite filters
should always be considered. Any filters supplied with the heat pumps should always be installed. The dirt strainer should be fitted on
the return line from the heating system, as close to the heat pump as possible.
Chemical and/or oil contamination shall always be avoided.
In areas where there are exceptional water conditions with regards to hard water, a softening filter may be necessary to use/install (applies to heating system, hot water and brine circuit). The softening filter softens the water, cleans any impurities and prevents the buildup of calcification.

3 Transport, unpacking and setting-up
3.1 Transporting the heat pump
Caution The heat pump must always be transported and stored upright in a
dry environment. Secure the heat pump so that it cannot tip over during transportation.
Caution If the heat pump is laid on the incorrect side it may become seriously
damaged, as the oil in the compressor may run out into the pressure
pipe and thereby prevent normal functioning.
3.1.1 Unpacking
1. Check that there are no transportation damages.
2. Remove the packaging.
3.1.2

3.2 Setting-up the heat pump
3.2.1 Recommended location
Positioning the heat pump
▪
The heat pump should preferably be placed against an outside wall (see chapter 'Heat pump data')
▪
Do not place the heat pump against walls facing noise-sensitive areas.
▪
Avoid placing the heat pump in the corner of a room.
Installation Guide
DHP-M
VIJSW102 Danfoss Heating Solutions

▪
If possible, choose a location where the surfaces nearest the heat pump are soft. Avoid placing the heat pump close to large plastered or tiled areas.
▪
The heat pump is fitted with internal vibration insulation. However, the degree of vibration insulation achieved depends on the
bearing strength of the surface the heat pump stands on. In order to achieve adequate vibration insulation, the heat pump should
be placed on a concrete floor with a thickness of at least 100 mm, or another surface with equivalent characteristics.
▪
In order to minimise noise generation from the heat pump, the sound plate (included) should be fitted when the heat pump has
been put into position.
▪
The heat pump must be level. Make sure to adjust feets in a way that the pump stands steady. If the feet is not adjusted correctly it
could cause some unwanted noise.
