  • The pump should be installed in an outside area with good air flows
  • Both the air inlet and outlet must be unobstructed with 2m clear space in front of the unit
  • A drain must be provided to allows condensate to disperse without flooding
  • Mount on a smooth, solid base designed to support the weight of the unit, fixed with bolts and using anti-vibration pads
  • The unit must be mounted vertically
  • The unit should not be near sources of pollution, corrosion or dead leaves
  • Do not place near other heat sources


  • The drain and overflow pipes should be installed over a suitable drain
  • When using plastic piping, expansion and contraction should be considered between the heat pump and the hot water tank
  • Insulation should be used on all pipework to prevent frost damage and heat loss


  • Bends in pipework should be minimised to reduce frictional energy losses
  • All pipes should be checked for leaks during installation and in periodic maintenance
  • On completion of installation, the pipework should be pressure tested, vented and filled with clean water dosed with approved inhibitor


  • Prior to installation check requirement for single or three phase power and confirm availability on site
  • The connecting supply must be isolated and secured in the off position prior to installation
  • Grommets must be used where cables enter electrical boxes
  • Power supply:
    • 220V +/- 10% 1 Ph
    • 380V +/- 10% 3 Ph
    • 50Hz +/- 2%

The performance figures for Aquarius are truly impressive, the build quality is reassuringly high, and the price is unbeatable.
