Caution

Caution

Before the heat pump is powered, you must ensure that the heating system and coolant system, including the heating pump, are full and bled; otherwise, their circulation pumps may be damaged.

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.

VIJSE302 Danfoss Heating Solutions

Commissioning DHP-M

Caution

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.

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

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.

Isolate the power supply to the heat pump while servicing the appliance 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.

Danfoss Heating Solutions VIJSE302 7

8

Commissioning DHP-M

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 released 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 Danfoss specifies, is used for refilling.

2.2.5

Scrapping

Caution When the heat pump is to be scrapped the refrigerant must be extracted for disposal. Local rules and regulations related to the disposal of refrigerant must be followed.

VIJSE302 Danfoss Heating Solutions

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 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 electrician and must follow applicable local and national regulations.

Caution The electrical installation must be carried out using permanently routed 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 corrosion 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 heating 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 exceptional 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.

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.

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 systems, 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.
