GENERAL INFORMATION

Important before installation


Connection to the hydronic system may ONLY be carried out by an authorised specialist.

Refrigerant pipes with a radius of less than 15 cm must NOT be bent.

Never connect power before the pipes have been routed and the system's modules are
interconnected and

the system is properly connected to the vented hydronic system.

The units are heavy and aluminium chips/sharp edges can cause cuts on your hands. Bend your
knees when lifting, and wear gloves and goggles during installation.

Read through all the operating and assembly instructions before commencing the installation.

The plastic plugs on the ends of the pipe must not be removed until the pipes are to be connected.

Check and tighten the coupling after 24h. Tightening of refrigerant couplings min. 18 Nm. Use a
torque wrench when in doubt. Make sure you have been supplied with an indoor unit and outdoor
unit with the same model designation.
ELECTRICAL SAFETY
New installations and extensions to existing systems must always be performed by a qualified electrician.
If you have the necessary experience and knowledge, you may replace switches and wall sockets, fit
plugs, extension cords and lamp holders. If not, you should contact an electrician. Improper installation
may result in electric shock or fire.

Important information


The heat pump uses environmentally-friendly R410A refrigerant, which has one of the highest
energy efficiency values in the industry. The unit is inverter controlled, which means that the
compressor has a variable speed to ensure better efficiency.

The energy the inverter delivers is monitored at all times by the system and is adapted in line with
external, internal and ambient factors to be as energy efficient as possible. This also means that
the amount of energy inside the system is regulated constantly which means the best possible
energy savings for the unit.

The control system with microprocessor contains well-proven and developed software that
optimises and controls operations, regardless of the internal and external conditions.

Special anti-vibration mountings and bushings ensure the indoor and outdoor units operate very
quietly.

Indicators that show the status of the machine and make it easy to monitor the system.

Soft start function with low power consumption for each compressor start-up.

Optimised night reduction allows the unit to run quietly and unobtrusively at night.

The auto-restart function allows the unit to find its previous settings automatically following a power
failure.

The unit must be connected to an earthed power outlet (230V/50Hz, 10A) surge protection,
residual current device and must have its own fuse (minimum 10A).

Pre-heater and heating coil are mounted in the outdoor unit for operation at low outdoor
temperatures. These help the inverter to maintain the temperature of the outdoor unit, which
reduces wear and extends the life of the compressor and facilitates drainage during defrost cycles.
These functions are controlled electronically and are based on the temperature outdoors.

An adaptive defrost system controls the outdoor temperature and changes the defrosting interval in
line with this for optimised operation.

Programmable "time-on" and "time-off" feature allows time-dependent control of the system.

Acrylic coated aluminium fins on the outdoor units allow rainwater to run off more easily, defrost to
work faster and reduces the risk of corrosion.

The heat exchanger is designed using the latest heat pump technology. By increasing the surface
area of the pipes you raise the efficiency of the heat emission.

Make sure you choose the correct size heat pump. The pump will normally cover about 50% of
your maximum energy needs for heating and can be docked to an existing system.

Heat pumps draw their energy from the outside air and the effect is reduced when the outdoor
temperature drops. It is therefore necessary to have additional energy from your existing heating
system when it gets colder outside.

The maximum water temperature is 50°C, the maximum recommended operating temperature is
45°C. It is important to note that the pump will not be able to reach maximum temperature without
the necessary support at lower outside temperatures or during excessive energy output.
