1. GENERAL INFORMATION
We thank you for your confidence in our products and congratulate you on making an excellent choice! You have
selected a long-lasting and environmentally friendly Lämpöässä geothermal heat system. We hope that you will enjoy
Lämpöässä’s heating system which will give you peace of mind for decades. It is important to read the user and
maintenance instructions carefully. Please retain this manual for future use and reference should problems occur.
1.1. Safety precautions
To ensure the Lämpöässä geothermal heat system operates in a trouble-free manner and in order to obtain the best
operating efficiency, the system must be transported and installed in accordance with the instructions provided by the
manufacturer. After installation is complete, the check list provided must be reviewed in order to minimise any instal-
lation errors. The manufacturer shall not be responsible for any breakages of equipment which is not installed correctly
or any costs incurred as a result of this.
The pipe and electrical installations for the Lämpöässä geothermal heating system can only be installed by qualified
persons. If problems occur during installation, we recommend that you contact your retailer or our maintenance
department. The telephone number for the maintenance department can be found in the documents delivered with the
Lämpöässä heat pump. Electrical connections for the installation of the Lämpöässä may only be set up by qualified
electricians.
In Lämpöässä T and P models – to prevent a compressor breakdown – the compressor and water in the storage tank
must be preheated for 6 hours before the heat pump is started for the first time. Press the motor protective switch down
and switch on the power. This stops the compressor starting and enables the electrical immersion to heat up the
compressor and water in the storage tank. The compressor can be started after 6 hours of preheating.
The warranty of the
Lämpöässä T
compressor is not
valid if preheating
is not carried out.
1.2. Transportation
The Lämpöässä heat pump must always be transported in a vertical position. If tilting the system is unavoidable, for
example to pass through a doorway, it may only be tilted to the left side or back as seen from the front of the heat
pump. The unit may be moved from beneath using a forklift, for example. Do not go underneath the equipment while
it is being lifted!
A transportation platform is fastened on both sides of the heat pump using screws. When the screws on the platform
are removed, the adjustable feet used for final installation can be found inside.
1.3. Installation area
We recommend that the Lämpöässä geothermal heat pump be installed in a warm space which has a floor drain. During
installation and when filling of the ground loop, some geothermal fluid mixture may be splashed on the floor. Glycol/water mixture
can be used as well. The chosen area does not have to be fireproof. The floor must be able to withstand the weight of the
heat pump and a full water tank. The floor must also be sufficiently even, because the heat pump must be as level as
possible. Final adjustments can be made using the adjustable feet underneath the equipment.
