Repair

  • if you know who installed the unit and they hold the appropriate qualifications, call them back to fix the unit to the manufacturer’s requirements

  • heat pump installation should only be carried out by experienced installers who are licensed to carry out the electrical work and hold the required certificate for handling refrigerants

  • the unit must be fixed on a firm base so it sits level, cannot fall over and has a minimum clearance of 100 mm underneath it. To reduce noise disturbance, units can be mounted on isolation mounting blocks or pads to absorb vibration. Fixings must be corrosion resistant – typically stainless steel

  • there is a Good practice guide for heat pump installation downloadable from the EECA website
