100% GEOTHERMAL HEAT
INSTALLATION INSTALLATION
Heating connection
Heat distribution circuit surface sensors located on top of the storage
tank must be installed to the distance of approx. 0.5 m from the three-
way or four-way valve. Circuit HD1 is always the main heating circuit
(rooms, for example); it is used for higher temperature (radiator heating,
for example). In case of compressor malfunction, the electric heating
element heats the circuit HD1 more efficiently. Circuit HD2 is used in
radiator-heated buildings for the possible floor heating share or for other
purposes (e.g., humid rooms). In these cases the circuits can be con-
trolled individually. The heat distribution circuits can be unconnected
through Summer Fuctions for summer. In this case e.g. HD2 in humid
rooms can only be used.
The pipes in the heating network are connected to the ground source
heat pump using either textile hoses (network of radiators) or using a
fixed piping network (floor heating). These connections prevent sound
from passing into the network. All heating connections (for example, a
heating radiator for an air conditioner or a heated towel rail) must be
made to the heat distribution circuits, not domestic hot water. When the
network piping is in place, filling may commence.
NOTE! Maximum storage tank pressure is 1.5 bar!
NOTE! If renovating, ensure that the heat distribution piping has been
properly rinsed before connecting the geothermal heat pump. If renova-
ting, installing a mud separator to the heat ditribution circuit is
recommended.
Speed controlling of the heat circulation pumps of Esi series
Heat circulation pumps with EMi/ELi-series determined by demand of the
heatable estate. Heat circulation pumps will be adjusted according to
manufacturer’s instructions.
Grundfos UPM3 AUTO heat circulation pump which is used in a HD
circuit can be set in three different controlling modes: proportional
pressure mode, constant pressure mode, constant curve mode.
Factory
setting is proportional pressure mode 3. In radiator network constant
pressure mode 1 or 2 can be used if sound of the flow water is distur-
bingly high.

Storage tank and heating system filling and de-aeration
The storage tank is to be filled with special care through the group of fill
valves included in the system so that the storage tank pressure never
exceeds 1.5 bar. While filling the storage tank, the air inside it must be
allowed to escape freely and not through air valve or safety valve, for
example. Suomen Lämpöpumpputekniikka Oy cannot be held respon-
sible for any expenses resulting from storage tank breakage in situations
where the tank has not been filled with water pursuant to the above
instructions.
There must be a de-aeration valve in the same branch with the group of
fill valves. The expansion vessel may be in the same branch as well. The
pipes in the network are filled with water.
