Ground Source Heat Pumps Since 1983

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.
