GENERAL INFORMATION
Important before installation
Refrigerant pipes with a radius of less than 15 cm must NOT be bent.
Never connect the power before the pipes have been routed and the system modules are
connected.
The units are heavy and aluminium chips/sharp edges can cause cuts on the hands. Bend your
knees when lifting, and wear gloves and safety glasses 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.
Retighten couplings after 24 h. Tightening torque for 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 operation, 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) with surge protection and
a residual current device, and must have its own fuse (minimum 10A).
A 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.
Acrylic coated aluminium fins on the outdoor units allow rainwater to run off more easily, defrosting
to work faster, and reduces the risk of corrosion.
Make sure you choose the correct size of heat pump. The pump will normally cover about 50% of
your maximum energy needs for heating and is an extra unit that does not replace 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.
In the event of disruption or indication of an error code, always start by turning off the heat pump
and cutting the power for 5 minutes.
Pull out the plug during thunder storms. Lightning can damage the heat pump. Do not, however,
leave the plug unplugged for long periods, especially during the winter, even if the unit has stopped
by itself.
Never use water, detergent, thinner or other cleaners to clean the indoor unit. We recommend
using a dry cloth.
