in a safe place in order to be able to use it as reference after installation. Remember to hand it over to the new owner if the heat pump

unit is sold or transferred. To prevent serious damage on the system and injuries to users, precautions and other notices shall be ob-

served.

Danger Risk of personal injury! Children are not permitted to play with the

product.

Danger Always disconnect a power supply of heat pump before servicing it or

accessing components inside the unit. (Have in mind that electrical

current is stored for a while in the condensator after you disconnect

the power supply)

Warning Verify that installation and testing operations must be performed by

qualified personnel.

Caution This manual explains how to install the air/water heat pump. The use

of other types of units with different control systems may damage the

units and invalidate the warranty. The manufacturer shall not be re-

sponsible for damages arising from the use of non compliant units.

Warning The manufacturer shall not be responsible for damage originating

from unauthorized changes or the improper connection of electric

and hydraulic lines. Failure to comply with these instructions or to

comply with the requirements set forth in the “Operating limits” table,

included in the manual, shall immediately invalidate the warranty.

Warning Do not use the units if you see some damages on the units, hear loud

noise, or the smell of burning.

Warning If the unit produces smoke, is very noisy or if any of the cables are hot

or damaged, always use the protection switch to turn off the unit and

contact the heat pump supplier.

tubes and protections regularly. These operations shall be performed

by qualified personnel only.

Warning The unit contains moving parts and electrical parts, which should al-

ways be kept out of the reach of children.

Warning Do not attempt to repair, move, alter or reinstall the unit by unauthor-

ized personnel, these operations may cause product damage, electric

shocks and fires.

Warning Do not touch the internal parts (water pipes, refrigerant pipes, heat ex-

changers, etc) while running the units. And if you need to adjust and

touch the units, have enough time for the unit to be cooled off and be

sure to wear protective gloves.

Warning In case of refrigerant leakage, try to avoid getting in contact with the

refrigerant because this could result in severe wounds.

Caution Inspect the product shipped and check if damaged during transport. If

the product has some damages, DO NOT INSTALL and immediately

discuss about the damages with the carrier or retailer (if the installer or

the authorized technician has collected the material from the retailer.)

Caution Always make sure that the power supply is compliant with local safety

standards.

Caution Install the power cable and communication cable of the indoor and

outdoor unit at least 1m away from the electric appliance.

any installation work!

Caution The heat pump must be installed by authorised installation engineers

and the installation must follow the applicable local rules and regula-

tions as well as these installation instructions.

Caution 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 un-

derstand the hazards involved. Cleaning and user maintenance shall

not be made by children without supervision.

Caution Make sure you wait before performing any work in the heat pump af-

ter turning off the power, because the unit contains capacitors which

may be charged.

Caution If there is a water heat tank it 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 wa-

ter tank. (DHP-iQ Maxi)

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, for exam-

ple copper. The safety valve overflow pipes must have an open con-

nection to the drain and visibly flow into this in a frost-free environ-

ment.

Caution Do not start the unit ( DHP-iQ Maxi) if there is a possibility of frozen

water in the immersion heater.

System solution DHP-iQ Mini

DHP-iQ Mini includes the control module with supply and return line sensors. The heat pump produces only heat or cooling. Two heat-

ing circuits can be connected, one using a shunt. The shunt is controlled by the heat pump control system. The flow line temperature is

controlled with reference to the outside temperature following a set heat curve. The additional heater starts automatically on demand.

Buffer tank is installed for equalisation of the temperature for the heating system and to guarantee sufficient energy when defrosting.

The buffer tank volume must be 20 l/kW heat pump output (for systems without water heaters).

During cooling, the shunt groups are controlled in the same manner in system solutions both with and without a buffer tank.

An addition to the system circuit is also implemented.

The by-pass valve for active cooling and buffer tank is controlled as follows:

When active cooling is activated, the valve does not release if heating of the buffer tank is required. Instead, the heat is sent to the

cooling circuit.

DHP-iQ Mini does not contain a water heater. Water heater is included in DHP-iQ Maxi.

For position explanations, see the chapter Symbol Key.

System solution DHP-iQ Maxi

DHP-iQ Maxi includes the control module with supply and return pipe sensors, circulation pump, 3-way valve, electric auxiliary heater

and water heater. The heat pump produces heat, cooling and hot water.

Production of heating and hot water cannot occur at the same time because the exchange valve for heating and hot water is positioned

after the heat pump and the auxiliary heater. Hot water production is prioritised ahead of heat and cooling. Two heating circuits can be

connected, one using a shunt. The shunt is controlled by the heat pump control system.

The flow line temperature is controlled with reference to the outside

temperature following a set heat curve. The additional heater starts automatically on demand. The auxiliary heater carries out peak heat-

ing charging (anti-legionella function) in those operating modes that permit auxiliary heat.

Buffer tank is installed for equalisation of the temperature for the heating system and to guarantee sufficient energy when defrosting.

The buffer tank volume must be 10 l/kW heat pump output (for systems with water heaters).

For postition explanations, see the chapter Symbol Key.

System solution intermediate exchanger

To safeguard against the pipes freezing an intermediate exchanger can be installed indoors. In such cases one must use glycol intended

for refrigerant applications in the circuit to the heat pump unit and an extra circulation pump.

Follow the supplier's instructions for mixing, but if none is given 35% is the lowest concentration recommended. To order and for more

information about the intermediate exchanger and the circulation pump, contact Danfoss.

Caution No glycol mixtures may be used in systems with hot zinc dipped pipes

or components.

4 Transporting, unpacking and setting-up

4.1 Transporting the heat pump

Caution During transportation and lifting of the entire heat pump, the front

panel must always be in place as it locks the other panels in position.

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 dur-

ing transportation.

Caution The heat pump must not be tilted more than 30° in any direction.

If the heat pump is tilted more, it may become seriously damaged as

the oil in the compressor can run out in the pressure pipe and there-

fore prevent normal function.

4.2 Unpacking

4.2.1 Unpack the heat pump

Warning Wear protective gloves to unpack, move, install, and service the unit to

avoid your hands being injured by the edge of the parts.

Caution Make sure to safely dispose of packing materials. Packing materials,

such as nails and other metal or wooden pallets may cause children

get injured.

N

All the materials used for the manufacture and packaging of the air to

water heat pump are recyclable.
