INTRODUCTION
Thank you for purchasing an IGLU® Aleut geothermal heat pump!
Our team hopes you will be satisfied with your new device and enjoy efficient heating, hot water and practically
free cooling for a long time.
In this manual you will find information on how to use and maintain the purchased geothermal heat pump
correctly. Keep this manual in a safe place for future reference.
IGLU® heat pumps are designed and selected for each facility to ensure maximum heating, cooling and hot
water preparation in the building.
IGLU® heat pumps are equipped with a convenient control system that allows to control the functions of the
heat pump, select individual settings and help to quickly find and eliminate faults. The device can also be
controlled via a mobile application. All you have to do is download the user-friendly IGLU® Home app (see,
page 8).
It is important to pay attention to the safety requirements that must be observed in order not prevent
injuries and enjoy the device for a long time.
CONCEPTS AND SYMBOLS
Water heater (boiler) is a device that performs a very important function –it prepares hot water.
Thermal disinfection (thermal shock) is a process in which the temperature of hot water in a water heater is
raised to at least 66°C and maintained for at least 1 hour. Thermal disinfection is used to prevent legionellosis,
i.e., to kill bacteria of the genus Legionella.
Glycol (heat carrier) –antifreeze that is used to fill up the heating system (outdoor circuit).
Heating water is a liquid harmless to the environment and health that is used to fill the indoor part of the heating
system (internal circuit).
Outdoor circuit is a part of a geothermal heating/cooling system located in the ground for the
collection/transmission of underground thermal energy. It can be horizontal or vertical (geothermal wells).
COP –coefficient of performance. The instantaneous ratio of thermal energy produced to electricity consumed to
produce that heat.
SCOP –seasonal coefficient of performance.
Electricity consumption –electricity consumption during the operation of the heat pump.
Thermal energy produced –heat energy produced during the operation of a heat pump.
“WARNING!” SYMBOL
Warning of minor heating system faults or parameter deviations. Errors are not critical, the system can continue
to operate.
“ATTENTION!” SYMBOL
System failure warning. The heat pump is stopped.

SAFETY
The device is safe to use as intended. The construction and design of the device comply with all safety
regulations. Prior to starting work, any person involved must read and be familiarised with the operating
instructions. This also applies if the person concerned has already worked on such or similar equipment or has
been trained by the manufacturer. Any person carrying out installation work must meet the health and safety
requirements. This is especially true when using personal protective equipment.
DANGER!
Danger of fatal injuries due to electric shock!
The electrical connection may only be installed by a qualified electrician.
Prior to opening the device, disconnect the system from the power supply
and prevent it from being switched on again!
WARNING!
Work on the device and its components may only be carried out by qualified specialists (heating,
refrigeration, coolant technicians and electricians).
WARNING!
Observe the safety signs on and inside the device.
WARNING!
The unit contains coolant!
If the coolant leaks, it poses risk to people
and the environment, therefore, you must:
– turn off the system;
– make sure the installation room is well ventilated;
– inform the manufacturer’s customer service.
ATTENTION!
For safety reasons, never disconnect the device from the power supply unless the device is open.
Do not use pure water in the outdoor circuit.
ENVIRONMENTAL PROTECTION
Environmental protection is a priority of IGLU TECH UAB. Product quality, cost-efficiency and environmental
protection are equally important to us. Therefore, we strictly adhere to environmental requirements. In order to
protect the environment and take into account financial possibilities, we use the best technologies and materials

PURPOSE
Geothermal heating is an alternative building heating system that uses free, underground heat. With the
help of a ground-to-water heat pump, this geothermal energy is extracted and used for heating, cooling and hot
water preparation in buildings.
Advantages of IGLU® Aleut heat pumps
Uses inexhaustible and ecological underground energy
Next-generation technologies and solutions ensure maximum efficiency and minimum cost
One device performs three functions –room heating, cooling and hot water preparation
Comfort at home can be controlled from anywhere in the world
HOW DOES A GEOTHERMAL HEAT PUMP WORK?
The principle of operation of a geothermal heat pump is similar to that of a refrigerator. Only in this case cold
output is directed outdoor or into soil, and the heat to the household.
The liquid (glycol) circulating in the outdoor circuit is heated by the heat accumulated in the ground, lake or
groundwater. As it flows through the heat pump, the liquid enters another closed system. It contains a coolant
called freon (refrigerant), which turns into gas at very low temperatures. The high-pressure compressor greatly
increases the temperature of the gaseous freon. The condenser supplies heat to the home heating system and
at the same time the freon becomes liquid again, ready to transform into gas again and store more thermal
energy.
PRODUCT PACKAGING AND TRANSPORTATION
IMPORTANT! After purchasing a heat pump:
Inspect the delivered product for external damage incurred during delivery;
In the event of delivery defects, submit a claim to the company that sold the device immediately.
The heat pump may only be transported and stored in an upright position. The device can only be temporarily
tilted, not laid down. The device can be stored at a temperature no lower than -10°C.

7
SELECTION OF THE INSTALLATION PLACE
When choosing the place of installation of the heat pump, mind that the heat pump produces a certain
level of noise (see, “Technical data according to European Commission Regulation No 813/2013”).
The device must be mounted on a flat and stationary surface with a permissible load of at least
300 kg/m2. Minor surface irregularities can be compensated by adjusting the feet of the device.
The ambient temperature near the heat pump must be between 10°C and 35°C, and the relative
humidity must not exceed 80%.
There must be no aggressive chemicals in the environment.
The heat pump should not be installed close to walls; the front of the unit should always be accessible
(see, Installation Manual “Heat pump installation drawing”).
A drainage system must be provided in the room where the unit is installed.
LOGO ILLUMINATION
The IGLU® Aleut heat pump has an illuminated IGLU®
logo on the front panel. The logo can be illuminated in
three different colours –blue, yellow or red. Each of them
has a corresponding meaning:
blue –heat pump on, normal operation;
yellow –warning about non-critical failure of the
heat pump or slight deviation of parameters from the
norm; the heat pump continues to operate, but it is
necessary to react promptly, within a reasonable
period of time;
red –heat pump failure, operation is stopped.
IGLU® HOME MOBILE APPLICATION
IGLU® Aleut geothermal heat pumps are controlled via the IGLU® Home
app. It allows to control the device and monitor the operating parameters
of the heating system, electricity consumption, thermal energy produced
and instantaneous or seasonal coefficient of performance in real time.

SYSTEM ERROR AND FAILURE INDICATIONS
If the symbol in the right corner of the main window is flashing or –
the system indicates a system error or fault. In the event of a system fault (bright
triangle), the heat pump will continue to operate, but every effort should be made to
rectify the fault. In the event of a system fault (dark triangle), the heat pump operation
will stop.
By clicking on the flashing symbol you will be redirected to the Active
Messages window (Window 6), where you will see a list of system errors and faults.
The full list of the meanings of these messages and possible causes is provided
below, as well as instructions on the actions the user should take.
When a non-critical issue is resolved, the error message disappears
automatically (without confirmation). After of elimination of other errors or a system
failure, they can only be confirmed from the local control panel. See, section Control
Panel on page 16. The fault is confirmed by pressing the Report button on the control
panel for >4 seconds.
