Do not block any passageways or thoroughfares.
Choose a location where the noise of the Air to Water Heat Pump when running and the discharged air do not disturb
any neighbours.
Choose a position that enables the pipes and cables to be easily connected to the other hydrauric system.
Install the outdoor unit on a flat, stable surface that can support its weight and does not generate any unnecessary noise
and vibration.
Position the outdoor unit so that the air flow directly stream towards the open area.
Place the outdoor unit where there are no plants and animals because they may cause malfunction of outdoor unit.
Maintain sufficient clearance around the outdoor unit, especially from a radio, computer, stereo system, etc.
