100% GEOTHERMAL HEAT
INSTALLATION
Filling and de-aerating a heating system fitted with a pressure gauge:
• Open the fill valve on the heating network.
• Fill the network with water.
• De-aerate the storage tank and network until all the air has been
removed and leave the pressure at 1-1.2 bar (max. 1.5 bar).
• Maximum pressures:
• Heating network storage tank – 1.5 bar
• Domestic hot water circuit – 9 bar
Domestic hot water connections and circulation of water
If there is no domestic hot water circulation at the site, make connections
pursuant to HVAC diagrams annexed to these instructions. Domestic
water is connected to the ground source heat pump pursuant to the
picture in Section 4.2.1. The same picture is provided on top of the unit,
under the roof. The mixing valve is fitted to the hot water pipe in order to
prevent burns. The overflow pipe is joined to the floor drain as instructed
or to an overflow funnel if the distance to the floor drain is more than two
metres. The overflow funnel must be directed down towards the floor
drain. The backpressure valve is fitted to the cold water joint on the input
side (see the annexed HVAC connections diagram).
NOTE! External radiators or dryers may not be connected to domestic hot
water circulation!
If the heatloss of the DHW circuit is considerd great it is recommended
to install an ÄssäStream heater (see more in the ÄssäStream brochure).
HVAC checklist
Check that
• the joints are tight and there are no leaking valves
• the expansion vessel on the heating system and fill side is prop-
erly installed
• the overflow pipe on the safety valve and the pressure gauge on
the heating system have been properly installed
• the heating system has been filled and de-aerated appropriately
• the ground circuit has been installed, filled and de-aerated
appropriately
4.3. Electrical installation and outdoor sensors
Only qualified electricians are permitted to carry out electrical work on
the heat pump according to general regulations.

The Lämpöässä heat pump is connected to a 400 V (50 Hz) electrical
network. The Lämpöässä heat pump has been fitted with an integrated
electrical switchboard which is permanently powered. The location of
the protection switch for the motor and other tripping devices are in the
electrical switchboard that is inside the heat pump. The electrical
switchboard is located at the top of the heat pump, under the plastic
roof. The plastic roof of the product is removed by lifting it from the
edges. A plastic-coated wire is used as a supply line, which wire travels
to the master switch in a casing pipe. The electrical switchboard cover
can be removed by undoing four screws on top of the switchboard.
While using the superheat function in Esi-model the connection plug
(XP11) of superheat circuit pump (P11) needs to be mounted to the
connection box. The connection box can be found from behind of the
heat pump front plate. More details can be found from the annexed
electrical connections diagram.
In the electrical connection of heat distribution pump (P12/P13) must be
used plug-ins included in the package. See the annexed electrical con-
nections diagram.
4.3.1. Outdoor sensor
In order for the outdoor sensor to recognise weather conditions as effec-
tively as possible, it must be placed in the correct location. The outdoor
sensor should be placed on the north-western or northern side of the
building to avoid the effects of the morning sun. If the sensor cannot be
placed as recommended, ensure that this is protected from direct sun
light.
