  • Page 4: Introduction

    (indirect solar energy) and, using a cooling process, transfer heat to your boiler system, thereby providing you with inexpensive energy. The Mecaterm ArctiQ model is a very reliable heat pump that operates at temperatures as low as –15ºC and produces water temperatures of up to 60ºC. The effectively sound-insulated compressor and the optimized heat exchanger offer high operating efficiency.

  • Page 5: Aqua

    Aqua uses the same reliable components as the related ArctiQ and ArctiQ EVI models, as well as being fitted with extra-thick sound insulation to reduce disturbing noise levels.

  • Page 6: Delivery

    Check the following points when your pump has been delivered and when installing the pump: • The ArctiQ, ArctiQ EVI and Aqua pumps must be transported and stored in a vertical position. • Remove packaging and check that the product has not been damaged in transit. Report any transit damage to the freight agent.

    RINE MEDIUM Dimensioning The collector for earth/bedrock/ground water/lake heat, etc. is dimensioned according to a computerised calculation program. Mecaterm can assist with this type of calculation. Insulation The indoor brine medium piping must be insulated with a moisture barrier material to prevent condensation from dampness.
  • Page 16 P a g e | 16 Brine fluid The brine medium should contain antifreeze medium, such as propylene glycol, to maintain fluidity down to temperatures of -15ºC. Collector hose The collector hose, PEM 40 x 2.4 PN 6.3, is used as standard. Every metre of hosing holds about 1 litre of fluid.

  • Page 25 | 25 Outdoor sensor Outdoor sensor must always be installed for the air/water models ArctiQ and ArctiQ EVI. For the Aqua heat pump it’s only necessary to install it if the system should operate at floating condensation which is described later in his chapter.
  • Page 26 P a g e | 26 Adjust the heating curve There are 3 ways to control how the heat pump will operate against the tank with floating condensation. Heat at outdoor temperature -15°C Default setting for heat at -15°C is 50°C, i.e. when outdoor temperature is -15°C the set point for heat pump will be 50°C.

  • Page 27: Controlling Of External Heat Source

    P a g e | 27 Summer time charge The last adjustment is a setting that gives possibility to change to set condensation at a desired outdoor temperature, often referred as “summer charging”. At the set temperature the heat pump starts to charge until return temperature reaches maximum set flow temperature - 12°C .

    In rare cases, a thin coating may form on the stainless steel. If this occurs, there are special cleaning agents available for stainless steel, such as Avesta OriginalFinish, a rust remover. This agent can be ordered from Mecaterm.  Check once a year that the inspection glass in the heat pump is clean and not filled with bubbles when in use.
