Caution When filling the coolant system the coolant pump must be operating;
you must ensure that the compressor and the heat transfer pump can-
not 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 de-
signed 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 cooling system (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.
Commissioning DHP-M
Danfoss Heating Solutions VIJSE302 7

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.
Commissioning DHP-M

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 isola-
ted before electrical installation is started. The heat pump is connec-
ted internally at the factory, for this reason electrical installation con-
sists 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
Caution A normal heating system always contains a certain amount of corro-
sion particulates (rust) and sludge products from calcium oxide. This
comes from acid that is naturally occurring in the fresh water that the
system is filled with. It is not good practice to have to fill the heating
system regularly which is why any leakage in the heating system
should be repaired immediately. Normal filling should occur only once
or twice a year. The water in the heating system should be as clean as
possible, always position the dirt filter on the return line from the heat-
ing system to the heat pump, as close to the heat pump as possible.
Caution Hard water; Normally it is not a problem installing a heat pump in
areas with hard water because the normal operating temperature for
the hot water does not exceed 60°C. In areas where there are excep-
tional prevailing conditions with the water one can install a softening
filter, which softens the water, cleans any impurities and prevents the
build up of calcification.

Danfoss Heating Solutions VIJSE302 9

2.5 Commissioning
Caution The installation may only be commissioned if the heating system and
brine system have been filled and bled. Otherwise the circulation
pumps can be damaged.
Caution If the installation is only to be driven by the immersion heater during
the installation, ensure that the heating system is filled and the brine
pump and compressor cannot be started.

3 Checking piping and electrical installation
3.1 Checking piping installation
During transportation and installation there is a risk that the heat pump may be damaged and components may move or become bent,
and this can cause abnormal noise. It is therefore important to check that the heat pump is free from defects after installation and before
commissioning.
Before filling the heating system, check the pipe installation according to the checklist below.

5.4 Adjusting the indoor temperature
The heat curve is a graph that compares the outdoor temperature with the supply temperature. The colder the outdoor temperature is,
the more heat is supplied to the heating system. The heat curve is adjusted during installation. It must however be re-adjusted later to
obtain a pleasant indoor temperature in all weather conditions.
For an explanation of the factory pre-set heat curve, see Adjusting the Heat Curve.
At an outdoor temperature of 0°C the supply temperature should be 40°C. Note that this is only a benchmark. There are radiator sys-
tems, floor heating systems and other types of heating system which require either lower or higher temperatures.
At outdoor temperatures below 0°C, supply line water hotter than 40°C is supplied to the radiators. Supply line water colder than 40°C is
supplied if the outdoor temperature is above 0°C.
A correctly set heat curve reduces the need for maintenance, as well as making operation more energy-efficient.
The indoor temperature is adjusted by changing the heat curve of the heat pump. This curve is the control system's tool for calculating
the correct supply temperature of water for the heating system.
