With buffer tank(s)
It is proposed, for more stable heat pump operations, that the
sensors are placed in the buffer tank/tanks. Normally the heating
sensor should be placed in the upper section and the cooling
sensor in the lower section.
Circulation pump
• The unit has a built-in circulation pump, that can circulate
water in the heating system that the unit is connected to.
• In larger systems, or in systems with a large pressure drop,
the built-in circulation pump is not sufficient and a secondary
circulation pump is needed in the system.
• An external circulation pump can be controlled from the
heat pump.
POSITIONING
NOTE:
May only be carried out by an authorised refrigeration technician.
• The indoor and outdoor units should be placed as near to
each other as possible. Short connections save energy.
• Do not install the indoor and/or outdoor units where they
can be exposed to moisture. This can cause electric shock,
corrosion and/or material damage. Damp and/or corrosive
environments can reduce the useful life of the heat pump.
Indoor unit
• Place the indoor unit on a level and stable surface.
• It should be placed close to the water supply and drain.
• The indoor unit should be placed in a dry, well-ventilated area.
• Do not place the indoor unit in explosive environments, such
as in the vicinity of flammable liquids, gases or dust.
• Do not expose the control panel to direct sunlight.
• Make sure to keep the unit upright when moving. If the unit
is tilted more than 30° it can tip over and cause personal
injury and/or material damage.
• Leave enough free space around the unit for maintenance.
FIG. 5
Outdoor unit
• The outdoor unit must be placed so that it has sufficient air
exchange, not inside a shed, carport or the like.
• Do not allow uninsulated refrigerant pipes from the indoor
unit to come into contact with the wall – condensation that
forms on the pipes can damage the wall and floor. Use the
insulation in the enclosed installation kit.
• When choosing the place to install the unit, bear in mind
that rotating parts can produce some noise and create
resonance.
• The outdoor unit should be placed in a dry and well-
ventilated area.
• Do not place the outdoor unit in explosive environments,
such as in the vicinity of flammable liquids, gases or dust.
• Put a roof cover over the outdoor unit to protect the air inlet
from snow, ice, and leaves etc. Protect the outdoor unit from
direct sunlight, rain and snow, but do not interfere with its
ventilation.
• Make sure that defrost condensation is led off from the area.
• If the outdoor unit is installed in an area where there is a lot of
snow or high relative humidity and/or temperatures below
0°C, it should be placed at least 50 cm above the ground.

INSTALLATION
NOTE:
•
May only be carried out by an authorised refrigeration
technician.
• The installer is responsible to ensure that the pressure
drop in the heating system is not greater than what the
built-in circulation pump can handle.
• The installer can select other installation procedures than
the one described below. Some fundamental specifications
apply for all system variants.
GENERAL GUIDELINES
Without buffer tank
It is proposed, for more stable heat pump operations, that the
sensors are positioned on the return pipe and that the heating
curve or cooling temperature is adapted according to the normal
delta T for the heating/cooling system.
