  • Page 3: Pre-Installation

    Pre-Installation Pre-Installation Important Site Instructions The installation, commissioning, inspection, maintenance and repairs must only be carried out by a qualified person. All electrical wiring must be completed by a licensed electrical contractor in accordance with the appropriate standards. The drilling work requires a permit from your local council. The heating system and heat source must be properly designed and dimensioned to ensure an efficient operation.
  • Page 4 Pre-Installation Note: ensure the correct refrigerant gas is used to recharge the unit as an incorrect gas can cause damage beyond repair to the compressor. Do not use oxygen to purge lines or to pressurize a unit for any purpose. Oxygen gas reacts violently with oil, grease and other common substances.

  • Page 5: Installation Location And Positioning

    Installation Location and Positioning Installation Location and Positioning The unit must be installed in a protected area that is free from rain and water penetration. The unit must be installed on a solid level surface, preferably on a concrete pad not connected to the main house slab foundation.

  • Page 6: Buffer Tank

    Buffer Tank Buffer Tank A buffer tank is recommended to ensure a trouble free heat pump operation. A suitable buffer tank can avoid excessive heat pump cycling (switching on and off). The buffer tank provides a hydraulic separation from the volume flow in the heat pump and heating circuits.
