2 Important information/Safety regulations

Warning! Risk of personal injury! Children are not permitted to play with the product.

Warning! As the water temperature in DHP-H Opti Pro and DHP-L Opti Pro becomes extremely hot, a mixer valve must be installed between the cold water and hot water pipes to ensure a lower domestic hot water temperature.Alternatively the maximum hot water temperature must be reduced in the Service menu.

Warning! Danfoss SP (1-phase) heat pumps have a factory installed safety valve for temperature and pressure, (10 bar 90-95°C), in accordance with the requirements in Great Britain. This valve is located in the water tank and may not be used for any purpose other than connecting the outlet pipe. Also note that for heat pump DHP-H Opti Pro SP and DHP-L Opti Pro SP it is imperative that the hot water temperature is changed from default setting 95°C to 85°C.

Caution! The heat pump must be installed by authorised installation engineers and the installation must follow the applicable local rules and regulations as well as these installation instructions.

Caution! This product 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.

Caution! The heat pump must be located in a frost-free environment!

Caution! The heat pump must be placed in an area with a floor drain.

Caution! The heat pump must be located on a stable base. The floor must be able to support the gross weight of the heat pump with filled hot water tank (see Technical data).

Caution! To prevent leaks, ensure that there are no stresses in the connecting pipes!

Caution! It is important that the heating system is bled after installation.

Caution! Bleed valves must be installed where necessary.

6 – Installation instructions VMBMA1002

Caution! The hot water tank must be equipped with an approved safety valve.

Caution! Heating systems with closed expansion tanks must also be supplied with approved pressure gauges and safety valves.

Caution! Cold and hot water pipes and overflow pipes from safety valves must be made of heat resistant and corrosion-resistant material, e.g. copper. The safety valve overflow pipes must have an open connection to the drain and visibly flow into this in a frost-free environment.

Caution! The connecting pipe between the expansion tank and the safety valve must slope continuously upwards. A continuous upwards slope means that the pipe must not slope downwards from the horizontal at any point.

Note! If there is any risk of groundwater infiltration at wall lead-ins for brine pipes, watertight grommets must be used.

Note! In addition to applicable local rules and regulations the installation should be carried out in a manner that prevents vibrations from the heat pump being transmitted into the house causing noise.

2.1 Refrigerant

Caution! Work on the refrigerant circuit must only be carried out by a certified engineer!

Although the heat pump cooling system (refrigerant circuit) is filled with a chlorine-free and environmentallyapproved refrigerant that will not affect the ozone layer, work on this system may only be carried out by authorized persons.

2.1.1 Fire risk

The refrigerant is not combustible or explosive in normal conditions.

2.1.2 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.

Warning! Risk of personal injury! Spaces in which heavy vapour can collect below the level of the air must be well ventilated.

Refrigerant vapour is heavier than air and, in enclosed spaces below the level of a door for example, and in the event of leakage, concentrations can arise with a resultant risk of suffocation due to a lack of oxygen.

Installation instructions VMBMA1002 – 7

Warning! Risk of personal injury! 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.

2.1.3 Work on the refrigerant circuit

Caution! When repairing the refrigerant circuit, the refrigerant must not be released from the heat pump, it must treated in the appropriate way.

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 from Danfoss are void if, when filling with refrigerant other than Danfoss A/S specified refrigerant, if there has not been written notification that the new refrigerant is an approved replacement refrigerant together with other remedies.

2.1.4 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.

2.2 Electrical connection

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. It must be possible to isolate the power supply using an all-pole circuit breaker with a minimum contact gap of 3 mm. (The maximum load for externally connected units is 2A).

DANGER! Hazardous electrical voltage! The terminal blocks are live and can be highly dangerous due to the risk of 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 mainly of the connection of the power supply.

2.3 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.

8 – Installation instructions VMBMA1002

Caution! If the installation is only to be driven by an auxiliary heater during the installation, ensure that the heating system is filled and the brine pump and compressor cannot be started. This is carried out by setting the operating mode to AUX. HEATER.

4 Transport, unpacking and setting-up

4.1 Transporting the heat pump

Caution! During transportation or lifting of the entire heat pump, the front panel must always be installed as it locks the other panels construction.

Caution! The heat pump must always be transported and stored in a dry area. Secure the heat pump so that it cannot tip over during transportation.

When transporting indoors to the installation location it may be necessary to place the heat pump on its back. The time that the heat pump is transported on its back should be as short as possible. After the heat pump has been lifted up again it must stand upright for at least an hour before commissioning.

4.2 Unpacking heat pump

4.2.1 Delivery check

1. Check that there is no transport damage. The heat pump is packaged in cardboard.

2. Remove the packaging and check that the delivery contains the following components.

4.3 Setting-up the heat pump

4.3.1 Recommended location

Part number 4-10 kW 12-16 kW

Caution! To avoid condensation problems for the brine lines, as short a brine line as possible is recommended indoors.

The heat pump should be located on a stable floor, preferably made of concrete. When locating the heat pump on a wooden floor this should be reinforced to take the weight of the heat pump including a filled water heater, see technical data for relevant heat pump. One solution is to place a thick metal plate, at least 6mm, under the heat pump. The metal plate should cover several joists spreading the weight of the heat pump over a larger area. If the heat pump is being installed in a newly-built house, this has normally been taken into account during construction, and the joists where the heat pump will be located have been reinforced. Always check that this has been carried out when installing into a newly-built house.

Avoid positioning the heat pump in a corner as the surrounding walls may amplify its noise. It is also important to adjust the heat pump using the adjustable feet so that it is horizontal to the base.

4.3.2 Space requirement

Caution! The heat pump must not be enclosed as the temperature inside the cabinet becomes extremely high.

To facilitate the installation and subsequent testing and maintenance there must be sufficient free space around the heat pump in accordance with the following image:

4.3.3 Setting up

Note! The heat pump has feet that can be adjusted to compensate for irregularities in the surface on which it is sitting. If the surface is so irregular that the feet cannot compensate for it, the installation engineer must remedy this.

Note! It is recommended that the condensation drain is installed from the drip tray’s drain pipe by lying the heat pump down. The drain pipe opens through a hole in the base plate and has a Ø10 mm hose connection.

Note! If the heat pump has been laid down it is recommended that it stands upright for at least an hour before commissioning.

4.3.4 Removing the front cover

Caution! Do not damage the electrical wiring for the display when the front cover is removed!

5.2.2 System solution 2

In system solution 2, the heat pump can produce both heat and hot water and an external auxiliary heater (oil boiler, electric boiler, district heating or similar) supports heat production but not hot water production. The exchange valve for heating/hot water is located ahead of the external auxiliary heater, which allows the production of heating and hot water at the same time.

The integrated auxiliary heater can be used for heating and hot water production as well as for antilegionella. The values of the integrals, A2 and A3 are used to select if the external auxiliary heater is to step in before or after the integrated electrical auxiliary heater.

The heat pump control computer also controls an additional shunt located after the external addition. For system solution 2, select in menu SERVICE\AUX. HEATER\EXTERNAL ADDITION: EXT.AUX.HEATER = ON REV.V. HOT WATER = INT

The brine pipes must be insulated from the heat pump, through the walls and outside the house all the way to the collector so as to avoid condensation and prevent heat loss.

If the brine pipes are to be routed above ground, drill holes in the walls for them. If the brine pipes are to be routed below ground see the instructions below.

Symbol explanation

1 Insert pipe 2 Brine pipe 3 Mortar 4 Sealant

Figure 32. Making holes

1. Drill holes in the wall for the insert pipes (1) for the brine pipes. Follow the dimension and connection diagrams. If there is any risk of groundwater infiltration at brine pipe lead-ins, watertight grommets must be used.

2. Position the insert pipes (1) in the holes sloping downwards. The inclination must be at least 1cm every 30cm. Cut them at an angle (as illustrated) so that rain water cannot get into the pipes.

3. Insert the brine pipes (2) into the insert pipes in the installation room.

4. Fill in the holes around the lines with mortar (3).

5. Ensure that the brine pipes (2) are centred in the insert pipes (1) so that the insulation is distributed equally on all sides.

6. Seal the insert pipes (1) with a suitable sealant (foam) (4).

5.3.6 Installing brine pipes

1. Determine to which side the brine pipes are to be connected.

2. Route the out pipe for brine in through the corresponding hole (with rubber collar) in the heat pump side.

3. Install all necessary components on the pipe. Remember to install the filler cock with the filter cover upwards.

4. Route the pipe for brine out through the corresponding hole (with rubber collar) in the heat pump side.

Caution! When the brine lines are connected to the right for DHP-A, the brine out line must be routed over the brine pump, under the compressor’s vacuum pipe and under the condenser’s flexible hose, see figure below.

Installation instructions VMBMA1002 – 35

Figure 33. The brine's supply line

1. Install the out pipe with all the accompanying components.

2. Install the expansion tank with the safety valve.

3. Fit both brine pipes with anti-diffusion insulation running all the way from the heat pump to the lead-in in the wall. The brine pipes running outside the house to the collector can be buried, however they must be well insulated.

Caution! Applies to DHP-A:Bear in mind that the outdoor unit may move during defrosts, use flexible hoses to connect the pipes from the heat pump and pipes on the outdoor unit.

5.3.7 Connection to outdoor unit

Connection for the brine circuit from the heat pump to the outdoor unit can be carried out using pipes or hoses. Depending on what connection is selected and what diameter the connection has, there is a maximum length that the connection may be. The maximum lengths in the table below are based on ethylene glycol (which is mixed to anti-freeze protection down to -32±1°C) at 0°C.

5.4 Noise information

5.4.1 Flexible hoses

Caution! The press sleeves may never be used as a counterhold when tightening connections.

All pipes should be routed in such a way that vibrations cannot be transmitted from the heat pump through the piping and out into the building. This also applies to the expansion pipe. We recommend that flexible hoses are

36 – Installation instructions VMBMA1002

used for all pipe connections to avoid the transmission of vibrations. Flexible hoses are available to purchase as accessories. The figures below show how appropriate and inappropriate installations look using this type of hose.

To avoid noise caused by pipe mounting, a rubber-coated pipe clamp should be used to prevent the transmission of vibrations. However, installation should not be too rigid and the pipe clamp must not be too tight.

Figure 34. Do not twist the flexible hoses as they are installed. At threaded connections, use a counterhold spanner

Figure 35. Cut the hose to the correct length to avoid excess bowing-out or stretching at bends.

10.7 Commissioning

10.7.1 Starting circulation pumps manually

If any of the circulation pumps do not start, it may need to be helped as follows:

Figure 47. Location of the bleed screw

Caution! When bleeding the circulation pumps, water can come into contact with electrical components. Therefore, protect the electric panel against water.

1. Open and remove the bleed screw on the front of the pump. Ensure to catch the water that runs out when the screw is removed.

2. Insert a flat blade screwdriver and turn it in the direction of rotation of the pump (clockwise).

3. Reinstall the bleed screw with its rubber seal.

10.7.2 Adaptation to the heating system

Adjust the heat pump settings to the applicable heating system, for instance an underfloor heating or radiator system. The delta temperature must be at least 8°C above the heat pump. The delta temperature should be 3–5°C for the brine system. If one of the ΔT is not reached, the flow of the circulation pumps may need adjusting depending on the applicable heating system.

Installation instructions VMBMA1002 – 69

10.7.2.1 Noise check

During transportation and installation there is a certain risk that the heat pump can be damaged, components may move or get bent and this can cause noise. Because of this it is important to check the heat pump when it has been installed and is ready to be commissioned to ensure that everything is in order. The heat pump should be tested in both heating and hot water modes to ensure that there is no abnormal noise. While doing this, check that there is no abnormal noise in other parts of the house.

Noise is produced from the outdoor unit when the fan is in operation, check during that manual operation that there is no disturbance in your own home as well as to any neighbours. A noise kit is available for purchase for the outdoor unit for DHP-A 10 and 12 if it is necessary to reduce the noise.

10.7.2.2 Select operating mode

Set the heat pump to the desired operating mode in the menu INFORMATION -> OPERAT. If necessary, set certain parameters in the control system, such as ROOM and CURVE.

10.7.3 Installing the front cover

Caution! Take care not to damage the front cover or display cables!

1. Hook on the lower edge of the front cover.

2. Carefully press the front cover’s upper edge towards the heat pump.

3. Turn the catch in the top panel 90 degrees clockwise.

10.7.4 After start up

Note! Remember that it takes time for the heat pump to heat a cold house. It is best to let the heat pump work at its own pace and NOT raise or alter any values in the control system to try to heat it up more rapidly.

Caution! If there is an alarm in conjunction with commissioning it usually means that there is air in the system.

10.8 Trimming the heating system

To obtain a heating system balance and obtain an even and comfortable indoor temperature, you must adjust your heating system according to the example below.

Note! Adjust the heating system during the winter to obtain the greatest possible output.

Note! Trimming must be carried out over a few days as the inertia in the heating system causes the indoor temperature to change slowly.

1. Choose one of the house’s rooms as a reference room for the indoor temperature, where the highest temperature is required, 20-21°C.

2. Place a thermometer in the room.

3. Open all the heating system’s radiator valves fully.

4. Leave the heat pump’s ROOM value set at 20°C. See Setting ROOM values for more information.

5. Note the temperature in the reference room at different points in time over a 24 hour period.

70 – Installation instructions VMBMA1002

6. Adjust the ROOM value so that the reference room reaches your required indoor temperature of 20-21°C. Remember that other rooms will have different temperatures during trimming, but these are adjusted later.

7. If the ROOM value must be adjusted more than 3°C upwards or downwards the CURVE value must be adjusted instead. See Adjusting CURVE values for more information.

8. If the indoor temperature varies several degrees despite trimming, a specific part of the heat curve may need adjusting. Check at what outdoor temperature the variation is greatest and adjust the curve at the corresponding value (CURVE 5, CURVE 0, CURVE -5). See Adjusting a specific part of the heat curve for more information.

9. When the reference room has an even temperature of 20-21°C over a 24 hour period, you can adjust the radiator valves in the other rooms so that their indoor temperatures are the same temperature or lower than the reference room.

10.9 Customer information

After commissioning is complete, the customer must be informed about their new heat pump installation. Below is a checklist regarding the information that the installer must give the customer:
