3. Heat source systems 3.1 General Information The given required area for geothermal heat pumps is related to average ground conditions (Soil, clay). The required collector size and therefore the area has to be increased for poor grounds (gravel). Contact your IDM-partner for further consultation. A pump trial run for 48 hours at the end of February and a water analysis is recommended for the use of groundwater. -

Page 21: Advice For The Installation
7. Advices for the Installation The heating and brine resp. groundwater circuits ha- ve to be pressure tested, neatly flushed, filled and ca- refully vented before the TERRA heat pump is put in- to operation. Requirements for system start up: The heating system as well as the buffer tank has to be filled and vented. -
Page 22: Operation
8. Operation The TERRA heat pump is switched on and off fully au- tomated by the Multi talent control. For a proper operation of the controls the manual has to be looked up. An annual service and maintenance of the installati- on by a customer service is recommended in con- cern of warranty claims. -
