5.2.2
Respect the distance between the domestic hot water
tank and the outdoor unit
A Domestic hot water tank
B Outdoor unit
1 Maximum number of elbows: 15
To ensure that the thermodynamic water heater functions correctly,
respect the minimum and maximum connection lengths between the
domestic hot water tank and the outdoor unit.
If the refrigerant connections are less than 2 m long, the following
disruptions may occur
Functional disruptions caused by a fluid overload,
Noise pollution caused by the circulation of the refrigerant.
1. Adhere to the dimensions opposite:
2. Make one or two horizontal loops with the refrigerant connections to
reduce disruption.
5.2.3
Selecting the location of the outdoor unit
To ensure the outdoor unit operates correctly, its location must meet
certain conditions.
1. Decide on the ideal location for the outdoor unit, bearing in mind the
space it requires and any legal directives and in relation to neighbours
as it is a source of noise.
2. Observe the IP24 protection rating of the outdoor unit during
installation.
3. Avoid the following locations:
Prevailing winds. Nothing must obstruct the free circulation of air
around the outdoor unit (intake and outlet).
Close to sleep zones,
Close to a terrace.
Opposite a wall with windows,
4. Ensure the support meets the following specifications:
Specifications
Examples
Flat surface that can support the
weight of the outdoor unit and its ac
cessories
Concrete base,
Sill,
Concrete blocks,
No rigid connection to the building served to avoid the transmission of vibration
Sufficient above ground elevation
(100 to 500 mm) to keep it above
water
Base with a metal frame to allow condensates to be discharged correctly.
The width of the base must not exceed the width of the outdoor unit.
The condensates discharge must be regularly cleaned in order to prevent any block
ages
Choosing the location of a noise abatement screen
When the outdoor unit is too close to neighbours, a noise abatement
screen can be fitted to reduce noise pollution.
