Distance between the domestic hot water tank and the outdoor
unit
Important
To ensure that the thermodynamic water heater functions
correctly, respect the minimum and maximum connection lengths
between the outdoor unit and the domestic hot water tank.

If the refrigeration connection between the outdoor unit and the domestic
hot water tank is less than 2 m, the following issues may arise:
Functional disruptions caused by a fluid overload,
Noise pollution caused by the circulation of the refrigerant.
Allow a refrigeration connection of at least 2 m by making one or two
horizontal loops in order to lessen these disruptions.
Position of the outdoor unit
Carefully choose the position of the outdoor unit in relation to neighbours
as it is a source of noise.
Warning
Nothing must obstruct the free circulation of air around the
outdoor unit (intake and outlet).
Do not place the outdoor unit close to where people sleep.
Do not place the unit opposite a wall with windows.
Avoid placing it close to a terrace, etc.
Choose a location away from prevailing winds.
Ensure sufficient above ground elevation (100 to 500 mm) to keep it above
water.
Always use a base with a metal frame sufficiently high off the ground to
allow correct condensates discharge. The width of the base must not
exceed the width of the outdoor unit.
Always install the outdoor unit sufficiently high off the ground to allow
correct condensates discharge.
Important
The condensates discharge must be regularly cleaned in order to
prevent any blockages.
Installing a noise abatement screen
In some cases, additional precautions are necessary owing to the fact, for
example, of too short a distance between you and your neighbours.
